.PREV DISCUSSION... /ISSUED 342 AM CDT SUN MAR 29 2015/

SHORT TERM...TODAY THROUGH THURSDAY NIGHT

THE LAST SUNDAY OF THE MONTH IS STARTING OUT A BIT ON THE CHILLY
SIDE WITH WIDESPREAD 30S TO A FEW LOWER 40S SHOWING ON THE LATEST
SURFACE OBSERVATIONS. CLOUDS ASSOCIATED WITH A WEAK UPPER WAVE THAT
BROUGHT LIGHT PRECIPITATION TO THE STATE SATURDAY HAVE FINALLY
CLEARED...LEAVING IDEAL RADIATIONAL COOLING CONDITIONS IN PLACE.
STILL CAN NOT TOTALLY DISCOUNT SOME FROST OVER THE NORTHEAST AND
WILL LET THE FROST ADVISORY CONTINUE AS IS ALTHOUGH IT WILL BE
PATCHY IN NATURE.

SHORT TERM MODELS REMAIN IN GOOD AGREEMENT THIS MORNING BOTH WITH
THE CURRENT FORECAST AND WITH EACH OTHER. THAT BEING SAID...WILL NOT
BE MAKING ANY REAL VALUE ADDED CHANGES TO THE GENERALLY UNSETTLED
FORECAST THIS MORNING.

HIGH PRESSURE CENTERED OVER THE OHIO VALLEY WILL BE MOVING TO THE
EAST TODAY PROVIDING THE AREA WITH SOUTHERLY WINDS AND TEMPERATURES
ON THE REBOUND IN RESPONSE. CLOUDS WILL BEGIN TO STREAM BACK IN
TONIGHT AS A SHORTWAVE TROUGH PROGRESSES EASTWARD ACROSS THE GREAT
LAKES WITH ITS ASSOCIATED SURFACE COLD FRONT STRADDLING THE
ARKANSAS/MISSOURI BORDER BY THE END OF THE DAY. NO PRECIPITATION
TODAY IS EXPECTED AT THIS TIME.

PRECIPITATION BEGINS TO DEVELOP ALONG THE BOUNDARY BUT NOT UNTIL IT
GETS TO THE CENTRAL AND SOUTHERN SECTIONS OF THE STATE. THE BOUNDARY
LOOKS TO SETTLE OVER THE SOUTHERN PART OF THE STATE WHERE IT WILL
BRIEFLY STALL BEFORE WASHING OUT. A COUPLE OF WEAK DISTURBANCES
WILL MOVE ALONG THE BOUNDARY FOR ONGOING PRECIPITATION CHANCES
BEFORE THE NEXT COLD FRONT APPROACHES THE AREA AS THE PERIOD
CONCLUDES. EVEN THOUGH PRECIPITATION CHANCES ARE IN THE FORECAST
MOST OF THE PERIOD...ACTUAL RAINFALL AMOUNTS WILL BE ON THE LIGHT
SIDE. TEMPERATURES WILL AVERAGE SLIGHTLY ABOVE NORMAL.

LONG TERM...THURSDAY THROUGH SATURDAY...

AN UPPER LEVEL WAVE WILL BE MOVING EAST OF THE STATE AT THE START
OF THE LONG TERM PERIOD...WITH SOME LINGERING RAIN CHANCES ACROSS
ERN SECTIONS OF THE STATE. HOWEVER...A COLD FRONT TO THE NW OF THE
STATE WILL DROP SLOWLY SE TOWARDS AR...AND WITH THE APPROACH OF
ANOTHER UPPER DISTURBANCE...HAVE INCREASING POPS FROM THE NW THU
AND THU NIGHT. THIS FRONT WILL DROP SOUTH THROUGH THE STATE FOR
FRI...BEING SOUTH OF THE STATE FRI NIGHT. POPS WILL REMAIN UP
THROUGH FRI...THEN DECREASE POPS FRI NIGHT AS THE DRIER AIR MOVES
INTO THE STATE FROM THE NORTH. HIGH PRESSURE WILL MOVE OVER THE
STATE FOR THE END OF THE FORECAST PERIOD...WITH PRECIP CHANCES
REMAINING LOW. TEMPS WILL REMAIN AT OR ABOVE NORMAL THU AND
FRI...THEN DECREASE BELOW NORMAL FOR SAT BEHIND THE FRONT. AT THIS
TIME...NO ORGANIZED SVR WX IS EXPECTED THROUGH THE PERIOD...BUT
WITH TEMPS ABOVE NORMAL SOUTH OF THE FRONT...COULD SEE AN ISOLATED
STRONG TO SVR STORM THU AND FRI.
