(FRIDAY THROUGH NEXT THURSDAY)

A WEAK DISTURBANCE ALONG THE GULF COAST TODAY WILL GENERATE THE
POTENTIAL FOR SCATTERED SHOWERS AND A THUNDERSTORM OR TWO ACROSS FAR
EASTERN CENTRAL ALABAMA. ACTIVITY SHOULD BEGIN THIS AFTERNOON ACROSS
SOUTHEASTERN AREAS AND SLOWLY SHIFT NORTH OVER THE FOLLOWING 12-18
HOURS, WITH ISOLATED TO SCATTERED SHOWERS FORMING PERIODICALLY
THROUGH THE EVENING AND OVERNIGHT. HIGHS WILL CLIMB BACK INTO THE
MID 80S TODAY AND SATURDAY, AHEAD OF AN APPROACHING COLD FRONT.
AN UPPER LOW OVER THE INTERMOUNTAIN WEST WILL MARCH EASTWARD TOWARD
THE GREAT LAKES OVER THE NEXT COUPLE DAYS. AN ASSOCIATED SURFACE LOW
OF COLORADO ORIGIN WILL JET NORTHEASTWARD ACROSS THE PLAINS AND INTO
NORTHERN MICHIGAN BY SATURDAY AFTERNOON. A TRAILING COLD FRONT WILL
EXTEND SOUTHWESTWARD INTO TEXAS AND WILL SLIDE EASTWARD AS SATURDAY
BECOMES SUNDAY. AHEAD OF THIS COLD FRONT, A LINE OF RAIN AND
THUNDERSTORMS WILL REACH THE MISSISSIPPI RIVER ACROSS MS/TN BY EARLY
SATURDAY AFTERNOON. A SEVERE RISK AREA IS CURRENTLY OUTLINED BY THE
SPC TO COVER MOST OF MISSISSIPPI AND WEST/NORTHWEST ALABAMA FOR
SATURDAY EVENING. AS THE LINE OF THUNDERSTORMS MAKES ITS WAY INTO
NORTHWEST CENTRAL ALABAMA BY SATURDAY EVENING, THIS LINE IS EXPECTED
TO POSE A DAMAGING WIND RISK BEFORE IT DECAYS AS IT REACHES THE I-65
CORRIDOR OVERNIGHT. LATEST CAMS SHOW POTENTIAL FOR CAPE VALUES AS
HIGH AS 800-1000 J/KG OVER WESTERN CENTRAL ALABAMA. INSTABILITY
WANES WITH THE LOSS OF DAYTIME HEATING ACROSS CENTRAL COUNTIES BUT
MAY STILL BE ON THE ORDER OF 500 J/KG. WITH THE SURFACE LOW WELL
REMOVED TO THE NORTH, IN ONTARIO BY LATE SATURDAY NIGHT, THE LACK OF
SUPPORT WOULD TEND TO SUPPORT THE NOTION OF A WEAKENING TREND DURING
THE OVERNIGHT HOURS.
MODELS ARE SHOWING POTENTIAL FOR WIDESPREAD 1-1.5" RAINFALL TOTALS
ACROSS MUCH OF CENTRAL ALABAMA SATURDAY INTO SUNDAY. UNFORTUNATELY,
THE LOWEST AMOUNTS WILL BE ACROSS SOUTHEASTERN AREAS THAT ARE
DEALING WITH MORE SERIOUS DROUGHT CONDITIONS. NBM PROBABILITIES
CONTINUE TO HINT AT THE POSSIBILITY FOR OVER 2" ACROSS NORTHERN AND
NORTHWESTERN COUNTIES, HOWEVER. THIS WILL NEED TO BE MONITORED IN
THE EVENT ANY ISOLATED FLOODING CONCERNS DEVELOP.
RAIN SHOULD CLEAR OUT OF THE AREA BY SUNDAY MORNING, WITH
DRASTICALLY LOWER DEW POINTS TAKING HOLD FOR MUCH OF THE WEEK.
SUNDAY THROUGH WEDNESDAY WILL FEEL MUCH MORE SEASONAL AS A SURFACE
HIGH WORKS EASTWARD ACROSS MUCH OF THE EASTERN UNITED STATES. HIGHS
WILL BE IN THE 60S TO 70S THROUGH MIDWEEK, STARTING TO CLIMB AGAIN
BY THURSDAY AS HIGHER DEW POINTS RETURN FROM THE SOUTHWEST.
