AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1149 AM CST MON MAR 2 2015

.AVIATION...
18Z TAFS...VFR CONDITIONS MAY PREVAIL AT MANY TERMINALS FOR A FEW
HOURS TODAY...BUT BY 00Z TO 06Z...LOW LEVEL MOISTURE WILL
INCREASE...RESULTING IN WIDESPREAD MVFR TO IFR CEILINGS. THESE
WILL CONTINUE INTO THE DAY ON TUESDAY. IN ADDITION...PATCHY
DRIZZLE AND FOG WILL LIKELY RESULT IN REDUCED VSBYS FROM KSPS/KLAW
TO KOKC/KOUN AND KPNC. SOME LIGHT RAIN MAY ALSO OCCUR...BUT MUCH
OF THIS ACTIVITY LOOKS TO REMAIN SOUTH AND EAST OF TERMINALS.
STILL CANNOT RULE OUT A STRAY SHOWER OR TWO...BUT CONFIDENCE IS
TOO LOW TO WARRANT MENTION IN THIS TAF ISSUANCE.

.PREV DISCUSSION... /ISSUED 1032 AM CST MON MAR 2 2015/

UPDATE...
CHANGES TO WEATHER TYPE THIS MORNING.

DISCUSSION...
WE HAVE REMOVED THE MENTION OF FREEZING DRIZZLE THIS MORNING.
TEMPERATURES ACROSS THE SOUTHERN HALF OF OKLAHOMA ARE APPROACHING
OR HAVE REACHED 32 DEGREES. BY THE TIME WE GET DRIZZLE OR LIGHT
SHOWER DEVELOPMENT TEMPS SHOULD BE ABOVE THE FREEZING MARK.

PREV DISCUSSION... /ISSUED 255 AM CST MON MAR 2 2015/

DISCUSSION...
LOW CLOUDS ARE EXPECTED TO HOLD ACROSS OKLAHOMA AGAIN TODAY WHILE
TEMPERATURES WILL CLIMB A BIT HIGHER THAN YESTERDAY`S. LIGHT
DRIZZLE WILL OCCUR IN SOUTHEAST OKLAHOMA THIS MORNING. MODELS
INDICATE THAT VERY LIGHT RAIN MAY MOVE SOUTHWEST TO NORTHEAST
ACROSS THE AREA TODAY. THERE ARE CURRENTLY RADAR ECHOES ACROSS
WEST TEXAS. AMOUNTS WOULD BE LIGHT. TUESDAY WILL BE A BIG
TRANSITION DAY. DEVELOPING SOUTHWEST WINDS ARE EXPECTED TO MOVE
OUT THE COOL AIR FROM WEST TO EAST; HOWEVER, A COLD FRONT IS STILL
SET TO ENTER NORTHERN OKLAHOMA AROUND MID-DAY BRINGING GUSTY NORTH
WINDS. RESIDENT MOISTURE AHEAD OF THE FRONT WILL BRING THE BETTER
CHANCES FOR RAIN AND THUNDERSTORMS TO AREAS EAST OF I-35. THIS
WILL QUICKLY BE REPLACED BY COLDER AIR AND A TRANSITION TO
FREEZING RAIN/SLEET/ SNOW NORTH TO SOUTH. LIGHT AMOUNTS ARE
FORECAST AND PRESENTLY POPS IN THE MIXED PRECIP AREAS ARE LESS
THAN 50 PERCENT FOR TUESDAY NIGHT AND WEDNESDAY. HOWEVER, THE
APPROACH OF A FAST-MOVING WAVE IN THE NORTHERN BRANCH OF
WESTERLIES ON WEDNESDAY MAY GIVE BETTER CHANCES FOR ACCUMULATIONS,
BUT THE INFILTRATION OF DRIER AIR WILL PRESENT A TIMING ISSUE.
BEYOND WEDNESDAY, THE WESTERLIES RETREAT TO THE NORTH OF OKLAHOMA
AND THE AIRMASS WARMS AND DRIES.
