.AVIATION /14Z FRIDAY THROUGH TUESDAY/...
AS OF 745 AM EDT THURSDAY...
THE MAIN CONCERN FOR THIS TAF PERIOD WILL BE GUSTY NW WINDS AS
THE PRESSURE GRADIENT INCREASES TO AROUND 8 MB ACROSS THE FORECAST
AREA THIS MORNING IN THE WAKE OF THE STRONG COLD FRONT THAT MOVED
THROUGH THE REGION LAST NIGHT. AS SUCH...WILL BE LOOKING AT WIND
GUSTS AS HIGH AS 30-35 KTS FOR ROA AND UP TO 25-30KTS FOR
BCB/DAN/BLF. WINDS OVERALL WILL BE THE STRONGEST AT ROA GIVEN THE
PATTERN. WINDS SHOULD DECREASE QUICKLY AFTER SUNSET AS TURBULENT
MIXING ENDS AND THE PRESSURE GRADIENT BEGINS TO RELAX AS STRONG
HIGH PRESSURE BUILDS SEWD FROM THE PLAINS.
WITH A NEAR WINTERLIKE PATTERN IN PLACE THROUGH THE TAF VALID
PERIOD...EXPECT IFR-LMVFR CIGS IN THE UPSLOPE TAF SITES ACROSS SE
WV...WITH DECREASING CLOUDS EAST OF THE ALLEGHANYS AS THE
DOWNSLOPE NW WINDS TAKE EFFECT AFTER DAYBREAK. CLOUDS SHOULD SCT
OUT TO SKC AFTER MID-MORNING EAST OF THE ALLEGHNYS...WITH SLOWLY
DECREASING CLOUDS THROUGH EARLY AFTERNOON IN SE WV. ALL SITES
SHOULD BE VFR BY LATE AFTERNOON. ISOLD -RA MAY PERSIST ACROSS SE
WV THROUGH MID-MORNING.
.EXTENDED AVIATION DISCUSSION...
HIGH PRESSURE TO KEEP US VFR THROUGH THE WEEKEND. MOISTURE
INCREASES AGAIN NEXT WEEK AS THE SFC HIGH MOVES EAST AND THE UPPER
RIDGE STRENGTHENS OVER THE MISSISSIPPI VALLEY. WILL BE GETTING TO
MORE HUMID WEATHER AGAIN WITH SOME THUNDERSTORM THREAT BY TUESDAY
AND FOG ISSUES AT NIGHT IN THE VALLEYS.
