559 PM CDT THU APR 2 2015

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
FOR THE 0Z TAFS... VFR CONDITIONS WILL PREVAIL AT ALL SITES
OVERNIGHT TONIGHT. HOWEVER... STRONG THUNDERSTORMS ARE EXPECTED TO
DEVELOP ACROSS MUCH OF THE REGION EARLY THIS EVENING AND MAY EVENTUALLY
ENCROACH ON THE VICINITY OF ANY TERMINAL. CEILINGS WILL LOWER
DURING THE NIGHT... WITH MVFR CONDITIONS PREVAILING DURING THE
EARLY MORNING HOURS. THUNDERSTORMS DIRECTLY AFFECTING ANY SITE
WILL LIKELY CREATE TEMPORARY IFR CONDITIONS WITH STRONG AND
UNPREDICTABLE WINDS.

&&

.PREV DISCUSSION... /ISSUED 340 PM CDT THU APR 2 2015/

DISCUSSION...
A VERY UNSTABLE ENVIRONMENT IS IN PLACE JUST AHEAD OF A SURFACE
BOUNDARY THAT CURRENTLY EXTENDS FROM SRN MO THRU SE KS AND INTO NC OK.
A STRONG CAP REMAINS IN PLACE...AND TO THIS POINT HAS NEGATED
CONVECTIVE INITIATION ACROSS THE AFOREMENTIONED AREAS. A FEW
SUBTLE FEATURES IN THE FORM OF AN UPPER DISTURBANCE AND MID LEVEL
WIND SPEED MAX ARE EXPECTED TO AID IN ERODING THE CAP. TIMING OF
THIS REMAINS IN QUESTION...AND ITS QUITE POSSIBLE STORM
DEVELOPMENT ACROSS NE OK AND NW AR HOLDS OFF UNTIL THE 00Z-02Z
TIME FRAME. THE INSTABILITY...AND STEEP LAPSE RATES THAT WILL BE IN
PLACE WHEN INITIATION OCCURS WILL ALLOW STORMS TO QUICKLY BECOME
SEVERE...WITH THE POTENTIAL FOR PRODUCING SIGNIFICANT SEVERE HAIL.
A TORNADO RISK WILL ALSO ACCOMPANY DISCRETE CELLS AS AMPLE
DIRECTIONAL AND SPEED SHEAR WILL BE IN PLACE. THE SURFACE FRONT
WILL EXHIBIT A FASTER FORWARD MOTION AS THE UPPER DISTURBANCE
DRAWS CLOSER LATER TONIGHT. THE SEVERE WEATHER RISK WILL DIMINISH
QUICKLY ACROSS NE OK AND NW AR ONCE THE FRONT PASSES LATER
TONIGHT.

COOLER CONDITIONS WILL SETTLE ACROSS THE AREA FRIDAY AND SATURDAY.
AS UNSEASONABLY COOL HIGH PRESSURE SETTLES OVERHEAD FRIDAY NIGHT
AND SATURDAY MORNING...LOW TEMPERATURES SATURDAY MORNING MAY FALL
AS LOW AS THE LOWER AND MIDDLE 30S ACROSS PARTS OF NORTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS. HIGH PRESSURE WILL SCOOT EAST
SATURDAY...AND MOISTURE WILL BEGIN TO RETURN AHEAD OF THE NEXT
SYSTEM THATS POISED TO MOVE ACROSS THE SRN PLAINS SUNDAY. THIS
WILL OFFER AREAWIDE RAIN AND THUNDER CHANCES...WITH THE BEST
CHANCES ANTICIPATED ACROSS SE OK AND WC AR AT THIS TIME.

SWLY UPPER FLOW WILL CONTINUE INTO THE MIDDLE OF NEXT WEEK. EARLY
NEXT WEEK...THE BETTER MOISTURE PROFILE WILL REMAIN ACROSS SE OK
AND NW AR...SO WILL SHADE SLIGHTLY HIGHER POPS IN THOSE AREAS. A
MORE SIGNIFICANT SYSTEM LOOKS TO IMPACT THE REGION BY THE MIDDLE
OF NEXT WEEK...AND WILL CARRY WITH IT ADDITIONAL STORM CHANCES
ALONG WITH A FRONTAL PASSAGE.
