DISCUSSION
KEY MESSAGE 1: MAINLY DRY FOR TODAY, THOUGH DAILY CHANCES
FOR SHOWERS AND THUNDERSTORMS RETURN ON MONDAY.
ONE AREA OF STRONG STORMS JUST SOUTHWEST OF SOMERSET CO.
THESE SHOULD PASS TO THE SOUTH OF OUR AREA, BUT COLD FRONT
WELL TO THE NORTHWEST STILL. MODELS BRING IN LOWER DEWPT
AIR INTO CENTRAL PA LATER TODAY, SO WILL GO WITH THE DRY
MODEL SOLUTION FOR NOW, BUT WOULD NOT BE SURPRISE SOMETHING
POPS UP TODAY.
AS THE AIRMASS DRIES OUT A BIT THIS AFTERNOON, TEMPERATURES
WILL LIKELY BE WARMER THAN IN PAST DAYS.
WARM AND MORE HUMID AIRMASS WORKS BACK INTO THE AREA ON
MONDAY, GIVEN RISE TO MORE SHOWERS AND STORMS.
AT THIS POINT, LOOKS LIKE THE MAIN CHANCE FOR STRONG STORMS
AND HEAVY RAIN WOULD BE MAINLY TO THE SOUTHWEST, MORE LIKE
OHIO INTO WV. NAM LOWERS DEWPOINTS AGAIN ON TUESDAY,
SUPPORTING MORE IN THE WAY OF DRY WEATHER AFTER EARLY TUE.
COOLER FOR LATE WEEK, BUT WITH WEAK SYSTEMS MOVING SOUTHEAST
IN A NORTHWEST FLOW PATTERN, COULD STILL BE WET AT TIMES.
AVIATION /07Z SUNDAY THROUGH THURSDAY/
OVERNIGHT, SCATTERED SHOWERS/THUNDERSHOWERS WILL CONTINUE ALONG
A SW-NE AXIS OF ENHANCED MOISTURE (AROUND 1.5" PWATS) AS A WEAK
COLD FRONT MOVES ACROSS THE NORTHEASTERN US, WITH CONVECTIVE
ACTIVITY DOWNTRENDING AS WE HEAD INTO THE DIURNAL MINIMUM &
UPPER-LEVEL SUPPORT IN LEFT EXIT OF WEAKENING JET STREAK AT 250
MB. AMPLE MOISTURE (SURFACE TD AROUND 70F REGIONWIDE) MAY RESULT
IN LOW STRATUS (MAINLY MVFR-IFR) ACROSS THE HIGHER ELEVATIONS
AT KBFD/KJST (08Z-14Z SUNDAY). AS DIURNALLY DRIVEN CUMULUS FIELD
DEVELOPS IN THE MORNING, MVFR CEILINGS ARE POSSIBLE (PRIMARILY
NORTHERN TIER AND CENTRAL MOUNTAINS, KBFD/KJST/KAOO/KUNV/KIPT)
GIVEN LOW-LEVEL MOISTURE IN PLACE, WITH REGIONWIDE VFR &
WESTERLY WINDS OF 5-10 KTS EXPECTED DURING THE
AFTERNOON/EVENING.
VFR CONDITIONS REMAIN FAVORED FOR MUCH OF SUNDAY NIGHT, WITH
MAINLY CLEAR SKIES GIVING WAY TO INCREASING CLOUDS OVERNIGHT

OUR NORTHERN TERMINALS (KBFD/KIPT) CLOSER TO THE SURFACE LOW,
