MBS

&&

.PREV DISCUSSION... /ISSUED 238 PM CDT FRI APR 3 2015/

DISCUSSION...
WINDS WILL BECOME LIGHT TONIGHT AS SFC HIGH MOVES INTO THE
REGION. THE COLDER AIR THAT HAS MOVED INTO THE AREA BEHIND THE
FRONT ALONG WITH LIGHT WINDS AND MOSTLY CLEAR SKIES WILL ALLOW
TEMPS TO FALL INTO THE 30S AND LOW 40S BY SATURDAY MORNING. SOME
LOCATIONS IN NORTHERN OK COULD SEE TEMPS AT OR A FEW DEGREES
BELOW FREEZING FOR A COUPLE OF HOURS TOMORROW MORNING. SOME LIGHT
FROST IS ALSO NOT OUT OF THE QUESTION ACROSS THE NORTHERN HALF OR
SO OF THE FA BUT DEWPOINT SPREADS ARE CURRENTLY EXPECTED TO BE
ENOUGH THAT IT WILL BE DIFFICULT FOR FROST TO DEVELOP SAT MORNING
SO WILL LEAVE A MENTION OUT OF THE FORECAST FOR NOW.

WINDS WILL GRADUALLY SHIFT TOWARDS THE SOUTH/SOUTHEAST SATURDAY
AND COULD BECOME BREEZY IN NORTHWEST PARTS OF THE AREA. MOISTURE
WILL BEGIN TO GRADUALLY SPREAD NORTH INTO PARTS OF THE FA DURING
THE DAY SATURDAY BUT HUMIDITIES WILL STILL BE LOW SAT AFTN...
ESPECIALLY IN NW OK. SO WITH LOW HUMIDITIES... HIGHS IN THE MID
60S... AND POSSIBLY BREEZY WINDS WILL CONTINUE WITH THE FIRE
WX WATCH FOR SAT AFTN. HOWEVER... THERE IS STILL A QUESTION OF
WHETHER THE WIND SPEEDS WILL REACH RED FLAG CRITERIA. IN
SOUTHWEST OK AND WESTERN NORTH TEXAS... WINDS ARE EXPECTED TO
REMAIN BELOW CRITERIA SO WILL CANCEL THE WATCH IN THESE AREAS.

MOISTURE WILL SPREAD BACK NORTH MORE AGGRESSIVELY SATURDAY NIGHT
INTO SUNDAY AS WAA DEVELOPS. THE WAA WILL PROVIDE LIFT FOR A
CHANCE OF SHOWERS/STORMS IN PARTS OF THE FA WITH THE BEST CHANCE
IN SOUTH CENTRAL/SE OK.

NEXT WEEK... THE DRYLINE WILL LIKELY BE IN OR NEAR PARTS OF THE
AREA THROUGH AT LEAST THURSDAY WHICH ALONG WITH DAYTIME HEATING
AND ANY UPPER LEVEL DISTURBANCES WILL BRING A CHANCE OF STORMS TO
AT LEAST PARTS OF THE FA PRETTY MUCH EVERY DAY. MODELS ALSO SHOW
A FRONTAL BOUNDARY NEAR OR IN PARTS OF NORTHERN OK WHICH COULD
ALSO PROVIDE SOME LIFT FOR CONVECTION. MODELS THEN SHOW UPPER
TROUGH FINALLY MOVING ACROSS THE CENTRAL U.S. LATE NEXT WEEK WITH
A COLD FRONT MOVING ACROSS PARTS OF THE AREA ALTHOUGH THERE IS
STILL A GREAT DEAL OF UNCERTAINTY WITH TIMING ETC. SOME SEVERE
STORMS WILL BE POSSIBLE NEXT WEEK. IN ADDITION... PARTS OF THE
AREA COULD SEE MULTIPLE DAYS OF ELEVATED FIRE WX CONCERNS...
ESPECIALLY IN WESTERN PARTS OF THE FA WHICH WILL HAVE THE BEST
CHANCE TO BE BEHIND THE DRYLINE AT TIMES.

&&

.OUN WATCHES/WARNINGS/ADVISORIES...
OK...FIRE WEATHER WATCH FROM SATURDAY AFTERNOON THROUGH SATURDAY
     EVENING FOR OKZ004>006-009>011-014>016-021-022.
