DISCUSSION...
LIFT CONTINUES TO INCREASE ACROSS WESTERN AND SOUTHERN PORTIONS OF
THE FA LATE THIS AFTERNOON AHEAD OF THE APPROACHING UPPER TROUGH.
THE DRIER AIR THROUGH THE DENDRITIC LAYER THAT WAS OBSERVED
THROUGH MOST OF THE AFTERNOON FROM AROUND OKC SOUTHWESTWARD IS NOW
STARTING TO FILL IN AS ANTICIPATED. STILL EXPECT SNOW AND SLEET
TO INCREASE OVER CENTRAL/SW OK NOW THROUGH THE EVENING COMMUTE.
ROADWAYS WILL BECOME SLICK DURING THIS TIME PERIOD...ESPECIALLY
JUST WEST AND SOUTHWEST OF THE OKC METRO. TOTAL SNOW AND SLEET
ACCUMULATIONS THROUGH LATE TONIGHT WILL RANGE FROM 1-3 INCHES FOR
MOST LOCATIONS...WITH THE POSSIBILITY OF SOME LOCALLY HIGHER
AMOUNTS MAINLY ALONG AND SOUTH OF I40 NEAR WEATHERFORD TO AROUND
ELK CITY. SOME PORTIONS OF THE OKC METRO COULD RECEIVE A LITTLE
OVER 2 INCHES OF SNOW AND SLEET COMBINED THROUGH LATE TONIGHT.

THE WINTER PRECIP WILL SLOWLY COME TO AN END FROM NW TO SE FROM
AROUND 06 TO 09Z. WE DID CONSIDER EXTENDING THE ADVISORY THROUGH
09Z ACROSS PORTIONS OF SE OK WHERE SOME HIGHER ICING AMOUNTS (JUST
LESS THAN 0.25 INCHES) MAY OCCUR...BUT WILL PASS THIS ON TO THE
EVENING SHIFT FOR NOW AS IT APPEARS THE TROUGH AXIS/MOISTURE
SHOULD SHIFT SE OF US BY THEN. OVERNIGHT...SKIES WILL BEGIN TO
CLEAR FROM NORTH TO SOUTH AND TEMPS WILL CONTINUE TO FALL INTO THE
TEENS. ROADS WILL REMAIN SLICK FOR THE MORNING COMMUTE THURSDAY.
THE HIGH TEMP FORECAST TOMORROW WILL BE TRICKY DEPENDING ON THE
LOCATION OF THE HEAVIEST SNOW BANDS...BUT HIGHS WILL LIKELY
STRUGGLE TO GET OUT OF THE 30S FOR MOST LOCATIONS. TEMPS WILL
CLIMB INTO THE 40S AND 50S BY FRI AFTERNOON UNDER CLEAR SKIES SO
ANY LINGERING SNOW LEFT ON THE GROUND THROUGH EARLY FRIDAY MORNING
WILL QUICKLY MELT. A WARMING AND DRYING TREND IS EXPECTED SAT
THROUGH MID NEXT WEEK.
