AVIATION...
IFR CONDITIONS ARE WITH LOW CEILINGS ARE EXPECTED IN SNOW THIS
MORNING IN WESTERN AND CENTRAL OKLAHOMA. LIGHT SNOW WILL GIVE WAY
TO PERIODS OF LIGHT SLEET AND FREEZING RAIN THIS AFTERNOON AND
OVERNIGHT. FREEZING FOG IS EXPECTED TO DEVELOP EARLY SUNDAY.

PREV DISCUSSION... /ISSUED 416 AM CST SAT FEB 28 2015/

DISCUSSION...
ANOTHER AREA OF LIGHT SNOW IS MOVING THROUGH WESTERN AND NORTHERN
OKLAHOMA THIS MORNING, LIKELY TO GIVE 1 TO 3 INCHES. LESSER SNOW
AMOUNTS ARE EXPECTED FARTHER SOUTH WHERE SNOW WILL MIX THROUGH THE
TRANSITIONS TO SLEET AND FREEZING RAIN AS STRONG WARMING OCCURS
ABOVE THE BOUNDARY LAYER AND WORKS IT WAY TOWARD THE SURFACE
THROUGH THE DAY. AS THE MAIN WAVE HELPING MORNING SNOW PRODUCTION
IN THE NORTH MOVES OFF TO THE NORTHEAST, LESS SYNOPTIC LIFT WILL
EXIST IN SOUTHERN AREAS, BUT THE WARM ADVECTION WILL STILL CREATE
A GOOD CHANCE THROUGH THE AFTERNOON FOR THE PRECIPITATION
TRANSITION. A WINTER WEATHER ADVISORY REMAINS EFFECTIVE THROUGH
THE DAY IN MOST AREAS. CURRENTLY WE EXPECT A CHANCE FOR FREEZING
RAIN SATURDAY NIGHT TRANSITION TO ALL RAIN BY MID-DAY SUNDAY.
BECAUSE POPS ARE RELATIVELY LOW, THE ADVISORIES WILL EXPIRE AT 6
PM TODAY.

A WEAK FRONT LATER SUNDAY WILL BRING A WIND SHIFT, BUT NOT MUCH
COLDER AIR. STRONG WARMING ALOFT AND MIXING TO THE SURFACE WILL
BRING TEMPERATURES INTO THE 60S TUESDAY AFTERNOON. MOISTURE AND AN
UPPER LEVEL WAVE WILL BRING RAIN TO SOUTH CENTRAL AND SOUTHEAST
OKLAHOMA AND A CHANCE ELSEWHERE BEFORE A COLD FRONT MOVES ACROSS
LATER IN THE DAY. AFTER A COLD DAY WEDNESDAY, DOWNSLOPE FLOW AND
THE EVENTUAL PASSAGE OF THE LINGERING UPPER LONG-WAVE TROUGH
SHOULD BRING DRIER AND WARMER CONDITIONS AFTER WEDNESDAY.
