.SHORT TERM...VALID FOR THU AND FRI...

OVERALL PACKAGE IN GOOD SHAPE THIS EVENING. CONVECTION CONTINUES
ACROSS NORTHERN ZONES AS EXPECTED. A SMALL AREA OF CONVECTION
STILL MOVING THROUGH CARTER COUNTY THIS HOUR. THIS IS REMNANTS OF
STORMS THAT MOVED THROUGH THE WESTERN PORTION OF THE FORECAST
AREA THIS AFTERNOON. A COLD FRONT IS PROGRESSING THROUGH THE
CENTRAL CWA. THERE COULD STILL BE AN ISOLATED SHOWER OR
THUNDERSTORM WITH THIS FEATURE ACROSS SOUTHERN ZONES
TONIGHT...HOWEVER MODELS CONTINUE TO INDICATE BEST CHANCES OF
PRECIPITATION WILL REMAIN NORTH OF THE I-90...I-94 CORRIDOR AS
INSTABILITY AND BETTER JET DYNAMICS REMAIN OVER THIS AREA.
INCREASED POPS IN NORTHERN ZONES TO SCATTERED FOR THE REST OF
TONIGHT TO HANDLE THIS. SOME CLEARING OCCURRING OVER SOUTHERN
ZONES IN AREA OF ENHANCED SUBSIDENCE ALOFT....THUS TWEAKED SKY GRIDS
FOR THIS. WITH SOMEWHAT CLEARER CONDITIONS EXPECTED...AND THE
ARRIVAL OF COOLER AIR BEHIND THE FRONT...SHOULD SEE TEMPERATURES
A FEW DEGREES COOLER THAN GOING FORECAST...ESPECIALLY WEST WHERE
HIGHS WERE ONLY IN THE 70S..AND THE LIVINGSTON VICINITY IS ALREADY
AROUND 60 DEGREES. WINDS MAY BECOME GUSTY FOR A TIME OVERNIGHT AS
MIXING BEHIND THE FRONT AND TIGHTENING PRESSURE GRADIENT WORK
TOGETHER TO INDUCE NORTHERLY WINDS ACROSS THE FORECAST AREA.

.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...

CONTINUED THE DRY EXTENDED FORECAST. MODELS WERE IN GENERAL
AGREEMENT WITH PATTERN THROUGH TUE...THEN HAD DIFFICULTY RESOLVING
POSITION OF PACIFIC TROUGH ON WED. GENERALLY ZONAL FLOW WITH WEAK
SHORTWAVES WILL BE OVER THE REGION SAT AND SUN. AIRMASS PROGGED TO
BE DRY SO NO POPS NEEDED. UPPER RIDGING WILL BUILD INTO THE AREA
FOR MON AND TUE. HOWEVER...BOTH GFS AND ECMWF HAD A SHORTWAVE
OVER ALBERTA/SASKATCHEWAN ON TUE WHICH MAY AFFECT THE AREA AS IT
MOVES SE. WILL WAIT TO SEE HOW THIS SITUATION EVOLVES IN FUTURE
RUNS BEFORE MAKING ANY CHANGES. WILL ALSO NEED TO WATCH EVOLUTION
OF PACIFIC TROUGH FOR THE MIDDLE OF NEXT WEEK. FORECAST FEATURED A
WARMING TREND. ONLY TEMPERATURE ADJUSTMENTS WERE TO NUDGE MAXES UP
A LITTLE ON SAT AND TUE. ARTHUR
