AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
400 AM CDT MON APR 11 2005

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT
UPPER TROF SLOWLY MOVING TOWARD THE AREA BUT THINGS STILL APPEAR TO
BE ABOUT ON SCHEDULE AS ADVERTISED BY THE MODELS OVER THE PAST FEW
DAYS. SHOWERS AND THUNDERSTORMS INCREASING TO THE SOUTHWEST AT ISSUE
TIME ABOUT AS EXPECTED AND RAIN SHOULD OVERSPREAD THE CWA THIS
MORNING AND CONTINUE THIS AFTERNOON WITH THE HEAVIEST IN THE SOUTH.
EVENING RAOBS SHOWED A SUBSTANTIAL CAP OVER THE AREA BUT THAT SHOULD
WEAKEN AS COLDER TEMPS ALOFT MOVE IN WITH THE APPROACH OF THE UPPER
TROF. INSTABILITY THIS MORNING WILL BE MARGINAL BUT MAY INCREASE
THIS AFTERNOON WITH A LITTLE HEATING AND POSSIBLY AN INCREASE IN
DEW POINTS. STARTED OUT WITH POPS RANING FROM 60 IN THE NORTHEAST
TO 90 IN THE SOUTHWEST BUT HAVE CATEGORICAL POPS IN ALL AREAS BY
MIDDAY THEN DECREASE POPS IN THE WEST LATE THIS AFTERNOON AS A SHORT
WAVE MOVES INTO THE AREA AND CLEARS OUT MOISTURE IN THE WEST. SEVERE
THREAT SHOULD NOT BE TOO HIGH THIS MORNING WITH LITTLE INSTABILITY
ALTHOUGH ISOLATED HAIL OR BOW ECHOES WITH WIND DAMAGE WILL BE
POSSIBLE. CHANCE OF SEVERE WILL INCREASE THIS AFTERNOON WITH MORE
INSTABILITY AND APPROACH OF THE SHORT WAVE. WENT WITH SEVERE WORDING
IN ZONES FOR THIS AFTERNOON. LARGE HAIL AND DAMAGING WINDS SHOULD BE
MAIN SEVERE WEATHER BUT ISOLATED TORNADOES CANNOT BE RULED OUT
ESPECIALLY IN THE SOUTH. ALSO WITH BEST UVVS IN THE SOUTH...HEAVIER
RAINS ARE LIKELY THERE AND MENTIONED HEAVY RAINS IN THE SOUTH HALF.
THE MAIN ACTIVITY SHOULD SHIFT TO THE EAST TONIGHT AND THE MAIN
SEVERE WEATHER AND HEAVY RAIN THREAT SHOULD BE OUT OF THE CWA BY 06Z
IF NOT SEVERAL HOURS SOONER. KEPT SEVERE WORDING FOR A COUPLE OF
HOURS THIS EVENING AND HEAVY RAIN WORDING FOR THE SOUTHEAST FOR
A COUPLE OF HOURS THIS EVENING. ALSO LEFT POPS AS THEY WERE FOR
TONIGHT WITH POPS DECREASING FROM THE WEST. UPPER LOW REMAINS JUST
TO THE NORTH THROUGH TUESDAY THEN IT SLOWLY SHIFTS TO THE EAST BY
WEDNESDAY. CLOSE PROXIMITY OF THE UPPER LOW TO THE CWA WARRANTS
KEEPING SMALL POPS IN THE NORTH TUESDAY THROUGH WEDNESDAY. COOLER
AND DRIER AND RESULTINGLY MORE STABLE AIR WILL BE IN PLACE...SO
WENT MAINLY WITH SHOWERS...BUT DUE TO COLD AIR ALOFT AND STEEP
LAPSE RATES...PUT ISOLATED THUNDER IN FOR THE AFTERNOON HOURS.
AS FOR TEMPS...LOOK FOR LITTLE RISE IN TEMPS TODAY WITH CLOUDS AND
RAIN DOMINATING THE AREA THROUGH THE MORNING. SOME AREAS IN THE
WEST MAY SEE TEMPS RISE SOME MORE THIS AFTERNOON AS RAIN DECREASES.
PRETTY MUCH FOLLOWED GUIDANCE FOR TEMPS BEYOND TODAY WITH LOWER
MINS LIKELY DUE TO DRIER AIR...MINS MOSTLY IN THE MID AND UPPER 40S.
MAXES SHOULD BE A LITTLE LOWER THAN IN RECENT DAYS ESPECIALLY IN THE
NORTH WHERE THE UPPER LOW MAY PRODUCE MORE CLOUDS. WENT WITH MAXES
TUESDAY AND WEDNESDAY NEAR OR A LITTLE ABOVE 60 IN THE NORTH AND
UPPER 60S TO AROUND 70 ELSEWHERE.
&&

.LONG TERM...THURSDAY THROUGH SUNDAY
EXTENDED RANGE SOLNS IN SLIGHTLY BETTER AGREEMENT THIS MORNING.
PERIOD STARTS OF WITH WANING MOISTURE OVER NORTHEASTERN
ARKANSAS...AS UPPER LOW FINALLY HEADS TOWARD THE ATLANTIC
COAST...AND H5 RIDGE BEGINS TO PUSH IN FROM THE PLAINS. MID-SOUTH
WILL BE IN BETWEEN TWO SYSTEMS...WITH SURFACE LOW OFF THE ATLANTIC
COAST...AND ANOTHER SURFACE SYSTEM DEVELOPING OFF THE ROCKIES. THIS
WILL KEEP FLOW NORTHEAST/EASTERLY FOR SEVERAL DAYS...WHICH WILL KEEP
TEMPERATURES TOLERABLE FOR THE MIDDLE OF SPRING /LOWS IN THE
50S...HIGHS IN THE 70S/.

BY LATE IN THE WEEKEND...RETURN FLOW WILL SET UP...WITH MOISTURE
INCREASING FROM THE SOUTH. COLD FRONT WILL APPROACH THE AREA FROM
THE NORTHWEST. HOWEVER...WITH A MID LEVEL RIDGE STRENGTHENING OVER
THE GULF OF MEXICO...THE SYSTEM WILL SLOW DOWN AND LIKELY STALL
INVOF THE MID OR LOWER MISSISSIPPI VALLEY. FOR NOW...CONTINUED WITH
A CONSERVATIVE APPROACH FOR THE LATTER PERIODS...WITH INCREASING
CLOUDS IN THE NORTH AND WEST...AND SLIGHT CHANCE POPS. GOING
FORECAST HANDLES TEMPERATURES VERY WELL...SO MADE VERY LITTLE
CHANGES WITH THAT PORTION OF THE FORECAST.

AN UPPER LEVEL LOW WILL CONTINUE IN MISSOURI TUESDAY INTO WEDNESDAY

OF SHOWERS. ISOLATED THUNDERSTORMS COULD DEVELOP DURING THE AFTERNOON
DURING THE HEAT OF THE DAY. PRESENT INDICATIONS ARE THE AIR WILL BE
LACK THE NECESSARY INSTABILITY FOR SEVERE THUNDERSTORMS BUT A FEW
THUNDERSTORMS WITH HAIL COULD DEVELOP TUESDAY AND WEDNESDAY
