AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
629 PM CDT FRI MAR 27 2009

.AVIATION...
LOW PRESSURE CONTINUES TO APPROACH FROM THE SOUTHWEST WITH A COLD
FRONT. THUNDERSTORMS WILL INCREASE ACROSS THE AREA THIS EVENING
AND CONTINUE OVERNIGHT. MVFR CONDITIONS ARE EXPECTED BUT IFR CAN
NOT BE RULED OUT. THE UPPER LOW WILL MOVE ACROSS CENTRAL ARKANSAS
SATURDAY AND KEEP RAIN IN MAINLY THE NORTHWEST HALF OF THE STATE.
RAIN MAY MIX WITH SNOW SATURDAY IN THE NORTH. THE UPPER LOW THEN
MOVES INTO INDIANA SATURDAY NIGHT.

&&

.PREV DISCUSSION... /ISSUED 249 PM CDT FRI MAR 27 2009/

SHORT TERM...TONIGHT THROUGH MONDAY NIGHT
UPPER LEVEL LOW PRESSURE AREA OVER THE PANHANDLES REGION WILL GIVE
THE SURFACE LOW PRESSURE SYSTEM OVER NORTH TEXAS AND ITS
ASSOCIATED BOUNDARIES A PUSH INTO THE MID SOUTH REGION TONIGHT.
SHOWERS AND THUNDERSTORMS WILL DEVELOP AND OVERSPREAD MUCH OF THE
FORECAST AREA THROUGH THE EVENING. THE SURFACE LOW IS CURRENTLY
NEAR DURANT OKLAHOMA. IT WILL HEAD NORTHEAST TONIGHT...AND WILL
DRAG THE WARM FRONT FURTHER INTO ARKANSAS THIS EVENING...AS WELL
AS THE COLD FRONT.

AS FAR AS THE SEVERE WEATHER THREAT...GREATEST SHOT AT TORNADIC
STORMS/WIND DAMAGE WILL BE SOUTH OF A LINE FROM MURFREESBORO TO
DE WITT...WHICH WILL BE IN THE WARM SECTOR OF THE SYSTEM. NORTH OF
THE WARM FRONT...ISOLATED ELEVATED HAILERS WOULD BE THE PRIMARY
THREAT.

THUNDER WILL BE WINDING DOWN AFTER ABOUT 06Z...AND DRY SLOTTING
WILL CUT OFF PRECIP FROM THE SOUTHWEST TO NORTH. SATURDAY
MORNING...THE UPPER LOW WILL BE MOVING INTO NORTHWEST ARKANSAS...
WITH PRECIP RETURNING. TEMPERATURES IN THE NORTHWEST WILL ACTUALLY
LEVEL OFF EARLY...AND WILL FALL THROUGH THE DAY. LITTLE CHANGE IN
TEMPERATURES WILL BE NOTED FROM SATURDAY MORNING THROUGH THE
AFTERNOON...WITH DIURNAL VARIATION LIKELY LESS THAN 10 DEGREES IN
MOST AREAS.

STILL LOOKING AT A RAIN/SNOW MIX ACROSS THE NORTHWEST AND NORTH
CENTRAL...BEGINNING DURING THE AFTERNOON SATURDAY. LOOKS LIKE
THERE WILL BE A CHANGEOVER IN THE EVENING...WITH PRECIP GRADUALLY
COMING TO AN END AROUND/SHORTLY AFTER MIDNIGHT. AS FAR AS
ACCUMULATIONS GO...STILL NOT LOOKING AT MUCH BUT MAYBE A FEW
TENTHS OF AN INCH IF ANYTHING AT ALL. AND...THAT WOULD BE LIMITED
TO GRASSY AREAS AND ELEVATED SURFACES...AND MAINLY IN THE HIGHER
ELEVATIONS.

UPPER LOW WILL BE PUSHING INTO THE OHIO VALLEY SUNDAY MORNING...
WITH SURFACE HIGH PRESSURE MOVING INTO THE REGION ON NORTHWEST
FLOW ALOFT.

COLDEST PERIOD WILL BE SATURDAY NIGHT/EARLY SUNDAY MORNING...AS
THE HIGH WILL BE OVER US. NORTHERN AND WESTERN ARKANSAS WILL
LIKELY SEE A FREEZE...WITH MID AND UPPER 20S POSSIBLE IN THE
WESTERN ARKANSAS RIVER VALLEY.

AS THE HIGH MOVES EAST SUNDAY NIGHT AND MONDAY...TEMPERATURES WILL
WARM BACK UP. TEMPERATURES WILL BE BACK IN THE LOWER 60S TO LOWER
70S BY MONDAY AFTERNOON. NEXT SYSTEM WILL MOVE THROUGH THE AREA
MONDAY NIGHT...BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS BACK
TO THE FORECAST.

LONG TERM...TUESDAY THROUGH THURSDAY
VIGOROUS UPPER LEVEL PATTERN CONTINUES THROUGH NEXT WEEK...BRINGING
A COUPLE SHORTWAVE TROUGHS ACROSS THE REGION. FIRST WAVE EXITS THE
REGION AT THE BEGINNING OF THE LONG TERM PERIOD...LIFTING NORTHEAST
INTO THE GREAT LAKES REGION. HAVE POPS DECREASING TUESDAY TO REFLECT
THIS SYSTEM EXITING THE REGION. WENT WITH A BLEND OF ECMWF/MEX
GUIDANCE FOR TEMPS...WHICH PUT HIGHS GENERALLY IN THE 60S FROM MID
TO LATE WEEK.

ANOTHER SHORT WAVE IS EXPECTED LATER IN THE WEEK...HOWEVER
CONFIDENCE IN THE TIMING AND STRENGTH ARE LOWER THAN THE MID WEEK
SYSTEM. GFS HAS A STRONGER SHORTWAVE MOVING A FURTHER SOUTH AND
SLOWER THAN THE ECMWF...WHICH PUSHES THE SHORTWAVE THROUGH BY MIDDAY
THURSDAY. THE GFS SOLUTION WILL GIVE BETTER POPS AND BETTER
POTENTIAL FOR STRONGER THUNDERSTORMS ACROSS THE STATE...BUT HAD HELD
THE SLIGHT CHANCE POPS FOR NOW GIVEN THE CONTINUING UNCERTAINTY WITH
THE LATE WEEK SYSTEM.

HAVE ALSO COMPARED TO BOTH THE GFS AND CANADIAN ENSEMBLES...AND THE
GENERAL CONSENSUS IS A CONTINUING LARGE SCALE TROUGH OVER THE
CENTRAL UNITED STATES...WITH SMALLER SCALE WAVES EMBEDDED IN THE
FLOW. HOWEVER...THE UNCERTAINTY REGARDING THE SMALLER SCALE SHORT
WAVES IS NATURALLY MUCH HIGHER. IN ANY CASE...EXPECTING THE ACTIVE
PATTERN TO CONTINUE THROUGH AT LEAST THE NEXT WEEK OR SO.
