605 AM EST Fri Nov 10 2017

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through
1100 UTC.

...ITCZ/MONSOON TROUGH...

The monsoon trough extends from Guinea Bissau on the African
coast near 12N16W to 09N17W. The Intertropical Convergence Zone
continues from 09N17W to 05N29W to 07N39W to French Guiana on the
coast of South America near 05N52W. Scattered moderate and
isolated strong convection is observed from 04N to 07N between
11W and 26W and from 04N to 06N between 41W and 46W.

...DISCUSSION...

GULF OF MEXICO...

A mid to upper-level trough extending SW from the Florida Big
Bend to the Bay of Campeche is supporting a cold front which
crosses the Gulf from near Tampa Florida at 27.5N83W to 24.5N94W.
The front then continues as a nearly stationary front to low pres
1016 mb centered near 24.5N96W to 22N94.5W to 18.5N95W. Convergent
upper-level winds over the Gulf are suppressing deep convection
in the vicinity of the front. Cloudiness, patchy rain and drizzle
are the result to the lee of the front. Gentle to moderate NNE
winds prevail south of the frontal boundary, while fresh to strong
N to NE winds are noted north and west of the front. Expect for
the front to move slowly SE and gradually weaken through Sat. The
front should stretch from southern Florida into the southwest Gulf
waters Sat evening. Moderate to fresh northeast winds are
expected on Saturday across much of the basin with the exception
of N to NW winds within 90 nm of the coast of Mexico south of 22N.
High pressure will build across the southeast CONUS over the
weekend and introduce a reinforcing shot of cold air into the
Gulf, causing NE winds to increase across the eastern Gulf and
Florida peninsula until early next week.

CARIBBEAN SEA...

A broad area of low pressure covers much of the basin, anchored
by a 1007 mb low centered S of Jamaica near 15N77W. A surface
trough curves NNE from low pres on the coast of Colombia near
12N75W to the low S of Jamaica, then through the Windward
Passage. Another trough curves NW from the low S of Jamaica to the
Yucatan Channel. Water vapor imagery indicates the surface low
and trough are supported aloft by a mid to upper-level low
centered near 16N81W. Low- level convergence primarily east of
the surface trough and upper level divergence east of the upper-
level low are combining to generate scattered moderate and
isolated strong convection from 10N to 20N between 70W and 77W.
Satellite-derived wind data show gentle to moderate N to NE winds
west of the surface trough while fresh to occasionally strong E
to SE winds prevail east of the trough. This broad area of lower
pressure across the basin is expected to persist and slowly lift N
through the upcoming weekend.

...HISPANIOLA...

Surface troughing extends from the Windward Passage to low pres
centered Caribbean S of Jamaica near 15N77W. The surface trough is
supported aloft by an upper-level low centered farther SW near
16N81W. Scattered showers and thunderstorms continue to develop
over the island. This activity will likely persist during the next
48 hours and maintain the threat of localized flooding and life-
threatening mud slides, especially if stronger convection develops
during peak daytime heating and instability.

ATLANTIC OCEAN...

A cold front extends SW from 32N78W to just north of Cape
Canaveral Florida near 29N81W, but there is no significant
convection associated with this boundary. A surface trough
extending SSW from the E coast of Florida near 28N81W to 24N81.5W
is supporting scattered showers over the Straits of Florida
between 80W and 84W. To the east, the surface trough continuing
NNE from the Caribbean through the Windward Passage to 29N67W is
providing the focus for scattered moderate and isolated strong
convection N of the Dominican Republic and NW of Puerto Rico in an
area bounded by 19N67W to 22N67W to 24N70W to 20N74W to 10N67W.
Upper-level troughing over the central Atlantic has induced a
surface trough extending from 19N48W to 30N48W. Scattered moderate
convection is seen from 17N to 25N between 43W and 48W. The
remainder of the basin remains under the influence of a broad
surface ridge, anchored by a 1041 mb high centered NE of the
Azores near 45N21W.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1247 AM CST Fri Nov 10 2017 Valid 111200Z - 121200Z ...NO CRITICAL AREAS... ...Synopsis... Quasi-zonal flow will continue across much of the CONUS Saturday. An upper shortwave trough will track east from the central and northern Rockies to the Mid/Upper MS Valley region. In response to this upper shortwave trough, deep layer westerlies will strengthen over the central and southern Rockies, and some breezy downslope winds are expected over NM into the southern High Plains. This will lead to lowering RH conditions during the afternoon with a deeply mixed boundary layer. However, surface wind speeds are forecast to remain less than 15 mph with some occasionally higher gusts. Additionally, RH values will remain marginal, precluding the need for any fire weather outlook areas. ..Leitman.. 11/10/2017 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1247 AM CST Fri Nov 10 2017 Valid 101200Z - 111200Z ...NO CRITICAL AREAS... ...Synopsis... Fire weather conditions are not expected to be a concern across the country today. Strong surface high pressure will dominate much of the eastern U.S. where seasonally cool and dry conditions can be expected. A low-amplitude upper shortwave trough over the Pacific Northwest will migrate east/southeast toward the Rockies and weak lee surface troughing will develop across the High Plains. This will result in some breezy conditions across the southern High Plains, but cool temperatures and unfavorable RH conditions will negate fire weather concerns here. ..Leitman.. 11/10/2017 ...Please see www.spc.noaa.gov/fire for graphic product...

Based on 0000 UTC surface analysis and satellite imagery through
0500 UTC.

...ITCZ/MONSOON TROUGH...

The monsoon trough extends from Guinea Bissau on the African
coast near 12N16W to 08N19W to 07N24W. The Intertropical
Convergence Zone continues from 07N24W to 07N38W to French Guiana
on the coast of South America near 05N52W. Scattered moderate and
isolated strong convection is observed from 04N to 08N between 14W
and 25W and from 04N to 06N between 41W and 46W.

...DISCUSSION...

GULF OF MEXICO...

A mid to upper-level trough progressing eastward over the NW Gulf
waters supporting a cold front extending SW from the Florida Big
Bend region near 28.5N82.5W to 25.5N90W to low pres 1016 mb
centered near 24.5N94.5W. The front then curves SW over the Bay of
Campeche to near Veracruz on the coast of Mexico near 19N96W.
Convergent upper-level winds over the Gulf are suppressing deep
convection in the vicinity of the front. Cloudiness, patchy rain
and drizzle are occurring to the lee of the front. A weak surface
trough possessing no significant deep convection extends from
23N92W to 20N93W. Gentle to moderate NNE winds prevail south of
the frontal boundary, while fresh to strong N to NE winds are
noted north of the front. Expect for the front to move slowly SE
and gradually weaken through Sat. The front should stretch from
southern Florida into the southwest Gulf waters Sat evening. Fresh
to occasional strong northeast winds are expected on Saturday
across much of the basin with the exception of northwest winds
within 90 nm of the coast of Mexico south of 25N. High pressure
will build across the southeast CONUS over the weekend, causing NE
winds to increase across the eastern Gulf and Florida peninsula
until early next week.

CARIBBEAN SEA...

A broad area of low pressure covers much of the basin, anchored
by a 1007 mb low centered S of Jamaica near 15N77W. A surface
trough extends from the low to the Windward Passage. Water vapor
imagery indicates the surface low and trough are supported aloft
by a mid to upper-level trough with an axis extending from over
the southern Bahamas and eastern Cuba to a base near 12N83W. Low-
level convergence primarily east of the surface trough and upper
level divergence east of the upper-level feature are combining to
generate scattered moderate and isolated strong convection from
11N to 20N between 69W and 76W. To the south, the monsoon trough
extends E along 10N to 79W, but all the significant convection
associated with this feature lies over the Pacific Ocean.
Satellite- derived wind data show gentle to moderate N to NE winds
west of the surface trough while fresh to occasionally strong E
to SE winds prevail east of the trough. This broad area of lower
pressure across the basin is expected to persist and slowly lift N
through the upcoming weekend.

...HISPANIOLA...

Surface troughing extends from the Windward Passage over the
SW Caribbean. The surface trough is supported aloft by an upper-
level trough with an axis extending from over the southern
Bahamas southwestward to a base near 12N83W. Scattered showers
and thunderstorms are occurring almost all of the island. This
activity will likely persist during the next 48 hours with the
potential for localized flooding and life-threatening mud slides,
especially if stronger convection develops during peak daytime
heating and instability.

ATLANTIC OCEAN...

A cold front extends SW from 32N77W to the coast of Florida near
29.5N81W, but there is no significant convection associated with
this boundary. A surface trough extending SSW from the E coast of
Florida near 27N80W to 24N81W is supporting scattered showers over
the Straits of Florida between 80W and 83W. To the east, another
surface trough extending from 29N64W to 22N70W is providing the
focus for scattered moderate convection N of the Dominican
Republic from 20N to 22N between 67W and 70W. An upper level low
across the central Atlantic is reflected at the surface as a
trough extending from 32N48W to 24N49W. Scattered moderate
convection is seen within 60 nm either side of a line from 18N44W
to 23N45W to 26N45W. The remainder of the basin remains under the
influence of a broad surface ridge, anchored by a 1041 mb high

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1645 UTC.

...SPECIAL FEATURES...
Tropical Storm Rina is centered near 47.0N 45.5W at 09/1500 UTC
or about 310 nm E of Cape Race Newfoundland and about 1285 nm SW
of Reykjavik Iceland moving NE at 35 kt. Estimated minimum
central pressure is 998 mb. Maximum sustained wind speed is 40 kt
with gusts to 50 kt. Scattered moderate convection is from 46N-
49N between 40W-44W. See the latest NHC Forecast/Advisory under
AWIPS/WMO headers MIATCMAT4/WTNT24 KNHC for more details.

...ITCZ/MONSOON TROUGH...
The monsoon trough extends from the African coast near 10N14W to
09N18W. The Intertropical Convergence Zone axis extends from
09N18W to 08N24W to 10N28W then resumes near 10N34W to 07N40W to
06N56W. Isolated moderate convection is from 03N-06N between
05W-14W...and from 03N-07N between 33W-40W. Scattered moderate
convection is from 09N-16N between 18W-32W.

...DISCUSSION...

GULF OF MEXICO...
A middle to upper level trough is progressing eastward over the
lower Mississippi River valley and NW Gulf waters this afternoon
supporting a cold front extending from the Florida Big Bend region
near 30N83W into a weak 1016 mb low centered near 26N96W then
southward to the Mexico coast near 21N97W. Widely scattered
showers and isolated tstms are occurring within 90 nm either side
of the front and across the SW Gulf in the vicinity of a surface
trough analyzed from 24N95W to 20N92W. Otherwise...gentle to
moderate northerly winds prevail S of the frontal boundary...
while fresh to strong N-NE winds are noted N of the front and N-NW
winds are noted W of the front. The front will be slow to move
southeastward through tomorrow and likely stall from the southern
Florida peninsula into the SW Gulf waters near 18N94W. Fresh to
occasional strong NE winds are expected on Saturday across much
of the basin with the exception of N-NW winds within 90 nm of the
coast of Mexico S of 25N. High pressure will build in through the
weekend across the SE CONUS...increasing E-NE winds across the
eastern Gulf and Florida peninsula into early next week.

CARIBBEAN SEA...
Generally broad lower pressure is noted across much of the
Caribbean this afternoon focused on a 1007 mb low centered near
12N76W off the coast of northern Colombia. A surface trough
extending N-NE from the low to the Windward Passage near 20N74W.
Water vapor imagery indicates the surface low and troughing is
supported aloft by a middle to upper level trough with axis
extending from over the SE Bahamas and eastern Cuba to a base
near 16N81W. Low-level convergence primarily E of the surface
trough and upper level divergence E of the upper level feature is
generating scattered showers and tstms from 13N-18N between 63W-
76W. In addition...scattered showers and tstms are occurring
across the SW Caribbean S of 12N between 74W-84W. Otherwise...W of
the surface trough...gentle to moderate northerly winds prevail
while moderate to fresh E-SE winds prevail E of the surface
trough. This overall broad area of lower pressure across the basin
is expected to persist through the upcoming weekend.

...HISPANIOLA...
Surface troughing extends from the Windward Passage region S-SW
into the SW Caribbean Sea supported aloft by an upper level trough
with axis extending from over the SE Bahamas southwestward to a
base near 16N81W. Low-level moisture convergence is maximized E of
the surface troughing with scattered showers and tstms occurring
across a large area from 13N-24N between 63W-74W. This convection
will likely persist for the next 48 hours with the potential for
localized flooding and life-threatening mud slides...especially if
stronger convection develops during peak daytime heating and
instability.

ATLANTIC OCEAN...
Water vapor imagery indicates a couple locations of mid-level
shortwave trough energy extending from over the mid-Atlc coast SW
to over Alabama and finally the NW Gulf of Mexico waters. The
troughing supports a cold front analyzed from 32N73W to the
Florida coast near Jacksonville and into the northern Gulf of
Mexico. A weak pre-frontal surface trough extends from the cold
front near 30N79W to near Port Everglades with isolated showers
and tstms occurring N of 28N W of 72W. Farther east...another
surface trough extends from 23N67W to 28N64W within the southern
periphery of a ridge anchored by a 1019 mb high near 30N63W.
Scattered showers and isolated tstms are occurring from 19N-24N
between 62W-72W. Across the central Atlc...an upper level trough
axis extends along 47W supporting a surface trough extending from
22N51W to 26N48W to 31N48W with widely scattered showers and
isolated tstms occurring N of 25N between 43W-46W. To the NE of
this convection...a surface ridge holds anchored by a strong 1042
mb high centered N-NE of the Azores near 45N22W. The influence of
the ridging covers much of the eastern Atlc N of 15N with NE
winds.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1253 AM CST Thu Nov 09 2017 Valid 101200Z - 111200Z ...NO CRITICAL AREAS... ...Synopsis... Progressive upper-level flow pattern will persist on Friday, though lower-amplitude and with weaker deep-layer flow. Weak lee troughing is expected across the southern and central High Plains as a subtle upper shortwave trough tracks across the Rockies and northern Great Plains. This will lead to some breezy southerly return flow across portions of the southern Plains with modest increases in surface dewpoints. Given expected cool afternoon temperatures, RH values will not be a concern and fire weather concerns are not expected. Further east, strong surface high pressure with light winds and seasonally cool temperatures will encompass the eastern U.S. and fire weather concerns are not anticipated. ..Leitman.. 11/09/2017 ...Please see www.spc.noaa.gov/fire for graphic product...
