.DISCUSSION...
HAZARDOUS DRIVING CONDITIONS MAY DEVELOP EARLIER THAN ANTICIPATED
FROM SW OK/NW TX THROUGH CENTRAL OK...INCLUDING THE OKC
METRO...THROUGH EARLY THIS EVENING. AN AREA OF LIGHT TO MODERATE
WINTRY PRECIPITATION CONTINUES TO EXPAND FROM WEST TEXAS THROUGH
NW TX THIS AFTERNOON...AND WILL IMPACT SW OK VERY SOON. LIGHT
SLEET AND FREEZING RAIN IS ALSO BEING OBSERVED/REPORTED ACROSS OK.
THE STRONGEST LIFT ASSOCIATED WITH THIS FIRST APPROACHING
SHORTWAVE TROUGH MOVING OUT OF WEST TEXAS IS EXPECTED TO IMPACT
CENTRAL AND SOUTH CENTRAL OK AROUND 21 TO 00Z. THE GFS AND HRRR
ARE PICKING UP NICELY ON THIS FEATURE...AND ALTHOUGH GFS QPF
APPEARS A BIT TOO AGGRESSIVE...IT WONT TAKE MUCH SLEET
ACCUMULATION TO CAUSE PROBLEMS AROUND OR JUST BEFORE THE RUSH HOUR
COMMUTE. SOME LOCATIONS ALONG AND WEST OF I44 SW OF
OKC...INCLUDING THE OKC METRO...COULD RECEIVE UP TO 0.25 TO 0.50
INCHES OF SLEET BEFORE SUNSET.

SOME SNOW COULD ALSO FALL NORTH OF THE I44 CORRIDOR AS THE DEPTH
OF THE COLD AIR INCREASES ALONG WITH WETBULBING...BUT SNOW
ACCUMULATIONS SHOULD REMAIN BELOW 0.5 INCH UNTIL LATER TONIGHT.
MORE DISCUSSION ON TONIGHT WITH THE STANDARD FORECAST
PACKAGE...BUT RIGHT NOW IT APPEARS THE FORECAST IS IN GOOD SHAPE
WITH MEAN ACCUMULATIONS AROUND 3 TO 5 INCHES ALONG AND JUST NORTH
OF THE I44 OK CORRIDOR BY LATE TOMORROW MORNING. FREEZING RAIN
WILL ALSO INCREASE WITH THIS INITIAL WAVE ACROSS S/SE OK BEFORE
00Z. SOME ICE ACCUMULATIONS THERE COULD APPROACH 0.25 INCHES
BEFORE SUNSET. ALL UPDATED PRODUCTS ARE IN THE PROCESS OF BEING
SENT.
