ALABAMA...SOUTHWEST ALABAMA...THE COASTAL WATERS OF ALABAMA AND
NORTHWEST FLORIDA...NORTHWEST FLORIDA AND SOUTHEAST MISSISSIPPI.
.DAY ONE...TONIGHT AND WEDNESDAY
SOME AREA RIVERS REMAIN IN ACTION OR FLOOD STAGE THROUGH FRIDAY.
PLEASE REFER TO THE LATEST RIVER FORECASTS FOR MORE SPECIFIC
INFORMATION ON RIVERS IN YOUR AREA.
AS A COLD FRONT HAS SINCE PASSED...A FREEZE IS IN STORE TONIGHT.
MINIMUM TEMPERATURES TONIGHT WILL RANGE FROM THE MID 20S INLAND TO
THE LOWER 30S ON THE BEACHES. THESE TEMPERATURES ARE DETRIMENTAL TO
OUTDOOR TENDER VEGETATION. THE LOW TEMPERATURES COMBINED WITH THE
FORECAST WINDS WILL MAKE IT FEEL EVEN COLDER...WITH WIND CHILLS
DIPPING DOWN INTO THE MID TEENS. THE DURATION OF THE FORECAST LOW
TEMPERATURES...IN THE MID 20S...DOES NOT APPEAR LONG ENOUGH TO
SUPPORT A HARD FREEZE WARNING AT THIS TIME. CONDITIONS WILL CONTINUE
TO BE MONITORED.
OVER THE MARINE AREA...STRONG OFFSHORE FLOW AND HIGH SEAS ARE
FORECAST OVERNIGHT. SEE THE LATEST MARINE WEATHER MESSAGES FOR MORE
SPECIFIC INFORMATION ON WINDS AND SEAS.
.DAYS TWO THROUGH SEVEN...WEDNESDAY NIGHT THROUGH TUESDAY
LOW TEMPERATURES INTO THE MID 20S TO AROUND 30 ARE EXPECTED AGAIN
THURSDAY MORNING.
SNOWFALL ACCUMULATION IS EXPECTED ACROSS OUR REGION BY WEEK`S END AS
A SURFACE LOW PRESSURE SYSTEM DEVELOPS AND MOVES EASTWARD ACROSS THE
NORTHERN GULF OF MEXICO THURSDAY NIGHT AND FRIDAY. PRECIPITATION
WILL LIKELY BEGIN AS A MIX OF LIGHT RAIN AND SLEET OVER THE INTERIOR
COUNTIES THURSDAY NIGHT...ESPECIALLY ALONG AND NORTH OF HIGHWAY

AFTERNOON BEFORE ENDING FROM THE WEST. CLOSER TO THE COAST...RAIN
WILL BEGIN FALLING THURSDAY NIGHT AND A CHANGEOVER TO SLEET AND SNOW
MIX COULD OCCUR AS EARLY AS MID MORNING FRIDAY BEFORE CHANGING TO
ALL SNOW BEFORE ENDING.
IT IS CURRENTLY BEYOND THE STATE OF THE SCIENCE TO PIN-POINT EXACT
SNOWFALL TOTALS BECAUSE IT IS TOO FAR OUT IN TIME PRIOR TO THE EVENT
MANY UNCERTAINTIES REMAIN. HOWEVER...CURRENT TRENDS INDICATE
SEVERAL INCHES OF SNOW COULD FALL OVER INTERIOR SOUTHWESTERN AND
SOUTH CENTRAL ALABAMA THURSDAY NIGHT THROUGH MIDDAY FRIDAY WITH
LIGHTER AMOUNTS CLOSER TO THE COAST. THE CONFIDENCE FOR
ACCUMULATING SNOW IN OUR AREA CONTINUES TO INCREASE...PARTICULARLY
INLAND.

BY TOMORROW AFTERNOON FOLLOWED BY EITHER AN ADVISORY OR A POSSIBLE
WINTER STORM WARNING BY SUNRISE THURSDAY. EVERYONE IS URGED TO STAY
UP TO DATE ON THE LATEST FORECAST AND OUTLOOKS CONCERNING THIS
POTENTIAL SNOW EVENT. ALTHOUGH PRECIPITATION WILL BE ENDING LATER
IN THE DAY FRIDAY...SUBFREEZING LOW TEMPERATURES FRIDAY NIGHT
SUGGESTS THAT LINGERING MOISTURE ON ROADS AND OVERPASSES WILL
REFREEZE...CREATING SLICK SPOTS AND HAZARDOUS DRIVING CONDITIONS.
NO HAZARDOUS WEATHER IS ANTICIPATED SUNDAY AND MONDAY.
.SPOTTER INFORMATION STATEMENT...
ACTIVATION OF STORM SPOTTERS AND EMERGENCY MANAGEMENT OFFICIALS FOR
SEVERE WEATHER WILL NOT BE REQUIRED THROUGH THURSDAY AFTERNOON.
