AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
1115 PM CST FRI FEB 20 2015

.AVIATION...
COLD FROPA CONTINUES TO ACCELERATE FASTER THAN EXPECTED AND IS
WILL CLEAR PVW MOMENTARILY...CDS BEFORE 06Z AND LBB AROUND 06Z.
SUSTAINED NLY WINDS ARE EXPECTED TO REMAIN SHY OF AWW CRITERIA
AT LBB /30 KNOTS/...HOWEVER AN HOUR OF GUSTS NEAR 40 KNOTS WITH
SOME BLDU IS LIKELY BEFORE WINDS SCALE BACK MARKEDLY TOWARD
DAYBREAK.

EARLIER THREAT OF LOW VISBYS IN FOG AT CDS IS QUICKLY DIMINISHING
GIVEN A FASTER FROPA...BUT WE STILL EXPECT IFR CONDS FROM LOW CIGS
TO ENVELOP CDS IN THE HOURS AHEAD. IFR CIGS ARE NOTED FROM HHF-
HBR AND CONTINUE EXPANDING SW. DRIER AIR BY DAYBREAK SHOULD
QUICKLY RESTORE VFR CONDS WITH DIMINISHING NELY WINDS.

.PREV DISCUSSION... /ISSUED 902 PM CST FRI FEB 20 2015/

UPDATE...
QUICK UPDATES TO INCREASE SKY COVER TONIGHT...ACCELERATE COLD
FROPA BY 1-2 HOURS...RAISE POST-FRONTAL WINDS...AND INTRODUCE
SOME FOG MENTION ACROSS OUR FAR NERN COUNTIES OVERNIGHT. FRONT
AS OF 830PM HAD ALREADY PUSHED THROUGH DUMAS WITH NORTHERLY
GUSTS TO 40 KNOTS AND AT THIS PACE SHOULD ENTER OUR NWRN ZONES
BY 11 PM. FARTHER EAST...FOG AND LOW STRATUS ARE QUICKLY EXPANDING
THROUGHOUT SWRN OK ON MOIST ELY WINDS AHEAD OF THE FRONT. SEE
LITTLE REASON WHY THESE LOWER VISBYS WON/T CONTINUE TO ADVECT
WEST INTO THE CHILDRESS AREA BEFORE FROPA IMPROVES VISBYS WITH
TIME.

&&

.LUB WATCHES/WARNINGS/ADVISORIES...
NONE.
