AL...NORTHWEST FL AND PARTS OF SOUTHEAST MS THROUGH TONIGHT. LATEST
RADAR AND SATELLITE TRENDS CONTINUE TO SHOW A LARGE AREA OF MODERATE
TO HEAVY RAIN MOVING NEAR AND ALONG A STALLED FRONTAL BOUNDARY THAT
IS CURRENTLY LOCATED OVER AREAS THAT WERE HARDEST HIT FROM PREVIOUS
FLOODING IN THE LAST WEEK. HOURLY RAINFALL RATES UP TO 1.5 INCHES
HAVE BEEN OBSERVED TO THE SOUTHWEST IN THE LAST COUPLE OF HOURS. WITH
THIS...RAINFALL TOTALS WILL LIKELY EXCEED THE 3 HR FLASH FLOOD

32/EE

&&

.MARINE...EXPECT PATCHY FOG THROUGH TONIGHT POSSIBLY LOCALLY DENSE
AT TIMES. PERIODS OF HEAVY RAIN WILL ALSO BE LIKELY THROUGH TONIGHT
REDUCING VISIBILITIES AT TIMES. 32/EE

&&

.AVIATION...

.PREV DISCUSSION... /ISSUED 540 AM CST WED DEC 30 2015/

NEAR TERM /NOW THROUGH WEDNESDAY NIGHT/...MAIN CONCERN FOR THE NEXT
24 HOURS WILL BE THE ONSET ON MORE RAIN POSSIBLY HEAVY AT TIMES
OCCURRING OVER AREAS THAT WERE HARDEST HIT FROM RECENT RAINS IN THE
LAST WEEK. SOME OF THE HI RES DATA SUGGESTS 2 TO 3 INCHES (LOCALLY 3
TO 5 INCHES) OF RAIN POSSIBLE ACROSS THE CENTRAL GULF COAST REGION
WITH THE HIGHEST AMOUNTS OCCURRING ALONG A STALLED FRONTAL STRETCHING
FROM THE MS COAST TO NE PARTS OF THE FCST AREA THIS MORNING. ALL THE
GUIDANCE SUGGESTS THIS BOUNDARY WILL DRIFT EAST THROUGH TONIGHT WITH
THE BEST MOISTURE CONVERGENCE POOLING ALONG THE FRONT SLOWLY SHIFTING
EASTWARD TO EASTERN AND COASTAL PARTS OF THE FCST AREA THROUGH 12Z
THU. LATEST FLASH FLOOD GUIDANCE IN THE WORST AREAS MENTIONED ABOVE
SHOW 3 HOUR AMOUNTS OF LESS THAN 3 INCHES FOR POSSIBLE FLASH FLOODING

NOW WILL CONTINUE TO MENTION LOCALIZED FLOODING POSSIBLE AND MONITOR
THIS SITUATION CLOSELY FOR ADVISORIES OR WARNINGS. THANKS AGAIN TO
SURROUNDING OFFICES AND WPC/HPC FOR YOUR COMMENTS ON THIS SITUATION.
OTHERWISE...SEVERE WEATHER IS NOT EXPECTED THROUGH TONIGHT DUE TO
LIMITED FORCING AND INSTABILITY AS COOLER AIR CONTINUES TO UNDERCUT
A LARGE MOIST LAYER...SETTING UP A WELL DEFINED OVERRUNNING EVENT
ACROSS THE REGION THROUGH TONIGHT. SORRY FOR THE LATENESS THIS
MORNING BUT THIS HAS BEEN A RATHER TOUGH FORECAST DUE TO THE HEAVY
RAIN AND ANTECEDENT CONDITIONS ACROSS THE FCST AREA ESPECIALLY TO
THE NORTH AND EAST. AS FOR TEMPS WILL USE A BLEND MAV AND CURRENT
FORECAST TEMPS FOR BETTER CONSISTENCY WITH SURROUNDING WFOS. HIGHS
TODAY WILL BE IN THE UPPER 50S TO LOWER 60S MAINLY WEST OF THE
STALLED FRONT AND THE MID 60S TO LOWER 70S TO THE EAST AND ALONG THE
COAST. LOWS TONIGHT WILL RANGE FROM THE UPPER 40S TO LOWER 50S TO THE
WEST AND THE MID 50S TO LOWER 60S TO THE EAST. 32/EE

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...DEEP GULF MOISTURE
WILL CONTINUE TO OVERSPREAD THE CENTRAL GULF COAST REGION.
CONVERGENCE ALONG STALLED FRONTAL BOUNDARY ALONG THE COAST WILL
CONTINUE OVER THE REGION THURSDAY AND THURSDAY NIGHT...THEN LIKELY
SLIP JUST OFFSHORE TO THE SOUTH FRIDAY AND FRIDAY NIGHT. THIS WILL
FOCUS THE HIGHEST RAIN CHANCES OVER THE EASTERN AND SOUTHERN PORTIONS
OF THE FCST AREA THROUGH THE SHORT TERM PERIOD. EXPECT LIKELY POPS
GENERALLY ALONG AND EAST OF A WIGGINS...LEAKESVILLE...GROVE HILL...
CAMDEN LINE THURSDAY AND THURSDAY NIGHT AND THEN SHIFTING DOWN
TOWARD THE COAST ON FRIDAY WITH CHANCE POPS DOWN ALONG THE COAST
FRIDAY NIGHT. POTENTIAL FOR HEAVY RAINFALL WILL CONTINUE ACROSS MOST
OF THE AREA THROUGH THE PERIOD...WITH 1 TO 2 INCHES LIKELY AND DOUBLE
THAT IN SOME LOCATIONS POSSIBLE. WILL HAVE TO CONTINUE TO MONITOR FOR
FLOODING PROBLEMS AND MAKE ADJUSTMENTS TO ANY FLASH FLOOD WATCHES
THAT MAY BE ISSUED...DEPENDING ON WHERE AND HOW MUCH RAINFALL OCCURS
DURING THE NEAR TERM PERIOD (AS MENTIONED ABOVE). MOSTLY SHOWERS
EXPECTED...BUT IN THE VICINITY OF WHEREVER THE FRONT IS LOCATED AND

UPPER 30S OVER NORTHERN INTERIOR ZONES AND IN THE LOWER 40S DOWN
CLOSER TO THE COAST. 12/DS

LONG TERM /SATURDAY THROUGH TUESDAY/...ON SATURDAY AND SUNDAY THE
