Area forecast discussion, from the National Weather Service, Norman

DISCUSSION…
MAIN FOCUS WAS ON THE PRECIPITATION TONIGHT THROUGH THURSDAY WITH
WINTRY MIX AND RAIN/STORMS.

A MID-LEVEL IMPULSE WILL MOVE ACROSS THE REGION TONIGHT INTO
WEDNESDAY MORNING LEADING TO PRECIPITATION. THE PRECIPITATION WILL
CONTINUE WEDNESDAY THROUGH THURSDAY AS THE MAIN UPPER SYSTEM MOVES
ACROSS THE SOUTHERN ROCKIES INTO THE CENTRAL/SOUTHERN PLAINS. RAIN
MAY BEGIN THIS EVENING IN SW PARTS OF THE FA. HOWEVER… THE
PRECIPITATION WILL INCREASE AFTER MIDNIGHT AND BE SCATTERED TO
WIDESPREAD WEDNESDAY/WEDNESDAY NIGHT. DRY AIR WILL THEN MOVE INTO
THE REGION THURSDAY WITH THE PRECIPITATION ENDING SOUTHWEST TO
NORTHEAST.

WINTRY MIX WILL BE POSSIBLE ACROSS APPROXIMATELY THE NORTHERN HALF
OR SO OF THE FA. HOWEVER… IN SOME LOCATIONS… THERE WILL LIKELY
BE A TIME PERIOD WEDNESDAY WHEN THE PRECIPITATION TRANSITIONS TO
JUST RAIN. FAR NORTHERN OK WILL HAVE THE BEST CHANCE TO STAY WITH
SOME SORT OF WINTER PRECIPITATION THROUGH THURSDAY. HOWEVER… THERE
ARE STILL QUESTIONS ON HOW FAR NORTH THE WARMER TEMPS WILL GO WHICH
WILL AFFECT THE LIKELIHOOD OF SNOW/SLEET OR MAYBE EVEN A BRIEF
PERIOD OF FREEZING RAIN. WHERE TEMPS STAY WARM ENOUGH WIDESPREAD
RAIN AND THUNDERSTORMS WILL AFFECT THOSE LOCATIONS BRINGING SOME
MUCH NEED RAINFALL TO THE REGION. SNOWFALL AND SLEET AMOUNTS OF 3 TO
5 INCHES ARE EXPECTED IN PARTS OF NORTHWEST OK SO WILL ISSUE A
WINTER STORM WARNING IN THESE AREAS. WITH SNOW AND SLEET POSSIBLE
FOR AREAS ALONG AND NORTH OF I-40 THAT DO NOT INCLUDE THE WARNING
AREA WILL ISSUE A WINTER WEATHER ADVISORY. DESPITE THE POSSIBILITY
OF PRECIP TRANSITIONING TO ALL RAIN FOR A BRIEF PERIOD OF TIME FOR
SOME AREAS… WILL KEEP THINGS SIMPLE AND HAVE BOTH PRODUCTS RUN
FROM 12Z WEDNESDAY TO 18Z THURSDAY AND LATER SHIFTS CAN ADJUST AS
NEED.

WITH THE MAIN FOCUS TODAY ON THE RAIN/WINTER PRECIPITATION OVER THE
NEXT COUPLE OF DAYS… DID NOT MAKE ANY CHANGES PAST THURSDAY.
