AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
556 PM CST MON MAR 2 2015

.AVIATION...
MAINLY MVFR CEILINGS WILL GRADUALLY LOWER TO NEAR IFR CONDITIONS THIS
EVENING/OVERNIGHT. A BETTER CHANCE OF DRIZZLE WILL BE SOUTH AND
EAST OF ALL TAF SITES...BUT WILL MENTION A CHANCE AT
LAW/SPS/OKC/OUN OVERNIGHT. THIS ALONG WITH SOME FOG...MAY REDUCE
VISIBILITY TO AROUND 2-3SM. WINDS WILL VEER AHEAD OF A STRONG
FRONT ON TUESDAY...WHICH WILL PROMOTE A BETTER CHANCE OF SUNSHINE
AND VFR CONDITIONS. THE FRONT WILL ENTER NORTHERN OKLAHOMA DURING
THE AFTERNOON HOURS TUESDAY.

.PREV DISCUSSION... /ISSUED 319 PM CST MON MAR 2 2015/

DISCUSSION...
THE MAIN CONCERNS THIS FORECAST ARE CENTERED ON ANOTHER ROUND OF
WINTRY WEATHER EXPECTED LATE TUESDAY THROUGH WEDNESDAY. WIDESPREAD
SNOW...SLEET...AND FREEZING RAIN ACCUMULATIONS WILL BE POSSIBLE
OVER MUCH OF OKLAHOMA AND NORTH TEXAS.

FOR THE REST OF TODAY AND TONIGHT...LOW LEVEL MOISTURE WILL
CONTINUE TO SURGE INTO THE SOUTHERN PLAINS...RESULTING IN
WIDESPREAD LOW CLOUDS...DRIZZLE...AND FOG. VISIBILITIES OVERNIGHT
INTO THE MORNING HOURS MAY FALL TO LESS THAN A MILE AT TIMES WHERE
MORE DENSE FOG DEVELOPS...BUT THIS SHOULD BE FAIRLY LOCALIZED.

TOMORROW...A COLD FRONT WILL APPROACH...AND WITH SOUTHWESTERLY
WINDS FOR THE FIRST PART OF THE DAY...RELATIVELY WARMER
TEMPERATURES ARE EXPECTED DURING THE DAY. HIGHS MAY FINALLY CLIMB
INTO THE 50S AND EVEN 60S IN SOME LOCATIONS. BUT DONT BE FOOLED!
OLD MAN WINTER IS SET TO REVISIT THE SOUTHERN PLAINS TUESDAY NIGHT
INTO WEDNESDAY AS AN ARCTIC FRONT SURGES SOUTH...REACHING CENTRAL
OKLAHOMA BY EARLY TUESDAY EVENING...AND MOVING SOUTH OF THE RED
RIVER BY MIDNIGHT.

WITH THE LARGE SCALE TROUGH HANGING BACK TO THE WEST...PLENTY OF
LIFT WILL FILL IN BEHIND THE FRONT...RESULTING IN WIDESPREAD
WINTRY PRECIPITATION TUESDAY NIGHT AND WEDNESDAY. PRECIPITATION
WILL GRADUALLY TRANSITION FROM RAIN...TO FREEZING RAIN...TO
SLEET...AND FINALLY SNOW OVERNIGHT TUESDAY NIGHT INTO WEDNESDAY.
THIS TRANSITION LOOKS TO OCCUR RELATIVELY QUICKLY...IDEALLY
PREVENTING SUBSTANTIAL ICE ACCUMULATIONS. HOWEVER...ICE
ACCUMULATIONS OF A TENTH OF AN INCH OR MORE WILL BE
POSSIBLE...ESPECIALLY OVER PORTIONS OF SOUTHERN AND EASTERN
OKLAHOMA SOUTH AND EAST OF I-44. SNOW ACCUMULATIONS WILL BE MOST
LIKELY OVER PORTIONS OF NORTHERN AND WESTERN OKLAHOMA...WITH
PERHAPS 1 TO 3 INCHES BY WEDNESDAY AFTERNOON. ELSEWHERE...FROM
WESTERN THROUGH CENTRAL AND SOUTHERN OKLAHOMA AND WESTERN NORTH
TEXAS...SNOW AND SLEET ACCUMULATIONS OF UP TO A HALF INCH LOOK
POSSIBLE. GIVEN THAT TEMPERATURES WILL FALL INTO THE MID 20S TO
LOW 30S IN THE POST FRONTAL AIR...ACCUMULATIONS OF SNOW/SLEET/AND
FREEZING RAIN WILL BE LIKELY ON ROADS...LEADING TO HAZARDOUS
TRAVEL CONDITIONS. AS THERE REMAINS CONSIDERABLE UNCERTAINTY IN
TIMING AND LOCATIONS OF MORE SUBSTANTIAL ACCUMULATIONS...WILL HOLD
OFF ON ANY ADVISORIES OR WATCHES FOR NOW...BUT AS CONFIDENCE
INCREASES...ADVISORIES WILL LIKELY BE NEEDED.

PRECIPITATION WILL END EARLY WEDNESDAY EVENING WITH DRY
CONDITIONS EXPECTED FOR THE REMAINDER OF THE WEEK INTO THE
WEEKEND. A NOTED WARMING TREND IS ALSO FORECAST...WITH
TEMPERATURES RISING INTO THE UPPER 50S AND LOWER 60S BY THE
WEEKEND.
