.DISCUSSION...

VERY DRY AIR IN THE 850-700MB LAYER HAS BEEN PERSISTENT THIS
EVENING...PREVENTING RAIN FROM REACHING THE GROUND ACROSS THE VAST
MAJORITY OF THE CWA. CLOUD BASES REMAIN QUITE HIGH AND THE FAR
SOUTHEASTERN COUNTIES HAVE OBSERVED SOME VERY LIGHT RAINFALL.
TRIMMED POPS SIGNIFICANTLY FOR THE OVERNIGHT WITH A TIGHT GRADIENT
ACROSS THE SOUTHEAST PART OF THE CWA. THE BACK EDGE OF MID TO
UPPER-LEVEL CLOUDS ARE ENTERING THE NORTHWEST COUNTIES AT THE
CURRENT TIME AND SHOULD CLEAR THROUGH THE CWA BY DAYBREAK. HAVE
DROPPED OVERNIGHT LOWS A COUPLE OF DEGREES ACROSS THE WESTERN HALF
AS A RESULT.

.AVIATION...
06Z TAF DISCUSSION.

COLD FRONT HAS NOW PASSED THROUGH TOI AND WILL CONTINUE TO CLEAR THE
AREA THROUGH 10Z. MOISTURE DID INCREASE OF THE SOUTHEAST...BUT WAS
ONLY ABLE TO 0.01 INCHES OF RAIN AT BEST. REMOVED THE RA FROM TOI
AND LEFT IN VCSH FOR THE TIME BEING ALTHOUGH ANY RAIN WOULD BE
EXTREMELY LIGHT. ALSO REMOVED THE MENTION OF MVFR CIGS AS THE
MOISTURE LEVELS JUST HAVE NOT BEEN MATERIALIZING THIS EVENING AND
THE BMX SOUNDING FROM 00Z SHOWS AN EXTREME DRY SLOT JUST BELOW THE
CLOUD DECK OF 10KFT.

WINDS WILL INCREASE FROM THE NORTHWEST AT 7-10KTS WITH SOME
VARIABILITY TO THE SOUTHWEST IN THE AFTERNOON...BEFORE SWITCHING
BACK TO THE WEST AFTER 3Z IN THE NORTH AND 6 TO 8Z IN THE SOUTHEAST.
