.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT

HIGH PRES WAS CENTERED TO THE E OF AR THIS AFTN...WITH A DVLPG SFC
LOW OVR THE NRN PLAINS. THIS RESULTED IN A BREEZY S/SELY WIND FLOW
OVR THE NATURAL STATE. MID AFTN TEMPS WERE A FEW DEGREES COOLER THAN
THIS TIME ON TUE...WITH READINGS RANGING FM THE 50S OVR ERN AR TO
THE 60S AND LOWER 70S ELSEWHERE.

THE AFOREMENTIONED SFC LOW TO THE N OF THE REGION WL CONT TO TRACK
EWD TNGT AND THU. MEANWHILE...A CDFNT TRAILING SWD FM THE LOW WL
SWEEP THRU AR LATE TNGT AND ON THU. WINDS WL SHIFT TO THE NW BEHIND
THE FROPA. MOISTURE LVLS RMN LIMITED WITH THIS SYS...SO NO RAINFALL
IS EXPECTED. COOLER AIR WL GRADUALLY FILTER SWD ON THU...WITH MILD
TEMPS STILL ANTICIPATED OVR CNTRL AND SRN AR.

THE COOLER AIRMASS WL BE MORE NOTICEABLE ACRS THE FA ON FRI...WITH
MOST LOCATIONS SEEING TEMPS FAIRLY CLOSE TO SEASONAL NORMS. CLOUDS

ORGANIZES OVR THE SWRN PART OF THE NATION.

.LONG TERM...SUNDAY THROUGH WEDNESDAY

LEFT HIGH END POPS IN FOR SUNDAY AS MODELS ARE IN GOOD AGREEMENT
WITH TIMING ON THE FROPA ENTERING THE REGION. THERE IS SOME
DISCREPANCY AS WE GET INTO SUNDAY NIGHT/MONDAY WHERE THE ECMWF WANTS
TO HOLD ONTO MOISTURE LONG AFTER THE COLDER AIR ARRIVES...MEANWHILE
THE GFS HAS MOST OF THE MOISTURE PUSHED SOUTH. WENT WITH A MODEL
BLEND FOR NOW WITH MENTION OF A BRIEF TRANSITION PERIOD OF RAIN/SNOW
SUNDAY NIGHT. MONDAYS HIGHS WILL CLIMB ABOVE FREEZING WITH LITTLE TO
NO ACCUMULATION EXPECTED FROM THIS SYSTEM.

MONDAY WILL BE THE COLDEST DAY OF THE WEEK...WITH TEMPERATURES
CLIMBING BACK UP TO SEASONAL AVERAGES BY TUESDAY WITH HIGHS IN THE
40S/50S.

IN THE MEANTIME THE NEXT WEATHER SYSTEM OF INTEREST WILL BE BREWING
IN THE GULF...PROGGED TO MOVE INTO THE MIDSOUTH TOWARDS THE END OF
THE PERIOD. THE ECMWF KEEPS THIS STORM SYSTEM JUST TO OUR SOUTH
WHILE THE GFS HAS A TRACK FURTHER NORTH. WENT WITH ANOTHER MODEL
BLEND APPROACH CONSIDERING HOW FAR OUT THIS IS...AND THE FLIP
FLOPPING THAT WILL LIKELY TAKE PLACE BEFORE EARLY NEXT WEEK.
