Area forecast discussion, Apr 5, 3:33 PM CDT, 2 hours 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
333 PM CDT THU APR 5 2012

.DISCUSSION...
SCATTERED SHOWERS AND THUNDERSTORMS THAT RECENTLY FORMED ACROSS
PARTS OF NORTH CENTRAL ALABAMA AND SOUTHERN MIDDLE TENNESSEE HAVE
MOVED FURTHER NORTH INTO MIDDLE TENNESSEE. OTHER ACTIVITY WAS TRYING
TO FORM OVER NW ALABAMA AND ESPECIALLY NORTHERN MISSISSIPPI. THE
LATTER WAS ASSOCIATED WITH THE COLD CORE UPPER LOW MOVING ACROSS THE
MID SOUTH. EARLIER...12Z ANALYSIS OF 500MB NOTED -20C TEMPS OVER
WESTERN MISSOURI/ARKANSAS ASSOCIATED WITH THAT LOW.

THIS ACTIVITY FORMED ON A FRONTAL BOUNDARY...THAT AS OF THIS WRITING
WAS NOTED APPROXIMATELY FROM NEAR NASHVILLE AND WINCHESTER...WEST OF
FORT PAYNE...AND NEAR BIRMINGHAM. ANOTHER MCS CONTINUED MOVING TO
THE SE FROM THE GULF COAST. A SIMILAR FEATURE YESTERDAY DELAYED
STORM DEVELOPMENT HERE. DRY SLOTTING WEST OF THIS BOUNDARY AND
FURTHER SURFACE DESTABILIZATION OVER THE TENNESSEE VALLEY MAKES FOR
A VERY CHALLENGING FORECAST OVER THE NEXT FEW HOURS.

THE APPROACHING UPPER LOW...WITH 700MB TEMPS -2 TO -4C WILL FURTHER
DESTABILIZE OUR LOCAL ATMOSPHERE...AND HELP BRING MORE BROAD SCALE
UPWARD MOTION/OMEGA. GIVEN STEEP ELEVATED LAPSE RATES...DESPITE
RATHER SLIM SURFACE MOISTURE AVAILABILITY...IT IS LIKELY THAT MORE
STORMS WILL FORM DURING THE LATE AFTERNOON AND EARLY EVENING. IN THIS
ENVIRONMENT...THE MAIN THREAT POSED BY THE SEVERE STORMS WILL BE
LARGE HAIL AND MARGINALLY SEVERE WIND GUSTS. THE STORM THREAT WILL
END FROM WEST TO EAST AS THE UPPER LOW EXITS THE AREA. COLDER AIR
MOVING BEHIND THE EXITING SYSTEM WILL PRODUCE SOMEWHAT COOLER
CONDITIONS THAT WE'VE EXPERIENCED AS OF LATE. LOWS TONIGHT AND FRIDAY
NIGHT/SATURDAY MORNING WILL FALL INTO THE LOW/MID 40S...WITH HIGHS
GOOD FRIDAY IN THE MID/UPPER 60S.

DESPITE THE COOLER SHOT...HIGH TEMPERATURES WILL MODERATE NICELY...
WARNING BACK INTO THE 70S FOR SATURDAY AND EASTER SUNDAY. THIS
WARMUP WILL SHORT LIVED...AS AN EVEN STRONGER COLD FRONT IS POISED
TO MOVE ACROSS THE AREA LATE MONDAY/EARLY TUESDAY. THIS WILL REDUCE
HIGH TEMPERATURES BACK INTO THE 60S. LOWS WILL FALL INTO THE UPPER
30S NE ALABAMA AND SOUTHERN MIDDLE TENNESSEE TO LOWER 40S NEAR THE
TENNESSEE RIVER AND SOUTH. THIS AGAIN IS SUGGESTIVE THAT PATCHY
FROSTING AND/OR A LIGHT FREEZE COULD OCCUR TUESDAY NIGHT/WEDNESDAY
MORNING. LAST NIGHTS GFS ENSEMBLE NUMBERS FOR HUNTSVILLE GO AS LOW
AS 39 TUESDAY NIGHT...WITH THE MODEL ITSELF SHOWING 40...AND THE
MORE RECENT 12Z RUN...41. TEMPERATURES AFTER THE MIDDLE OF THE WEEK
SHOULD GRADUALLY RECOVER INTO THE UPPER 60S...A TAD BELOW RUNNING
SEASONAL NORMS IN THE LOWER 70S.

.AVIATION...
/ISSUED 1241 PM CDT THU APR 5 2012/
FOR 18Z TAFS...VFR CEILING HEIGHTS AOA 20K FT WILL PERSIST THROUGH
20Z BEFORE LOWER CEILINGS AROUND 4K FT OVERSPREAD THE AREA FROM W TO
E. UPPER LOW/WEAK COLD FRONT PUSHING INTO THE LOWER MS VALLEY WILL
ALSO RESULT IN CLUSTERS/BANDS OF SHRA/TSRA DEVELOPING ALONG/AHEAD OF
THE SFC BOUNDARY. IFR VIS/ADDITIONAL FUEL REQUIREMENTS MAY DEVELOP
IN/NEAR THE HEAVIER TSRA MAINLY THIS AFTERNOON. VFR CEILING HEIGHTS
WILL THEN GRADUALLY BEGIN TO CLIMB THIS EVENING/AFTER 00Z FRI...WITH
SHRA/TSRA DIMINISHING WITH THE PASSAGE OF THE COLD FRONT. SFC WINDS
WILL ALSO BE TURING TOWARD THE N AOA 10KT LATER TONIGHT.
