.PREV DISCUSSION... /ISSUED 310 PM CDT FRI APR 18 2014/

DISCUSSION...
IN THE WAKE OF YESTERDAYS FRONT...WINDS HAVE SHIFTED BACK TO THE
SOUTH AND EAST...MAKING FOR A MILD AND PLEASANT AFTERNOON. SIMILAR
CONDITIONS WILL BE FELT TOMORROW AS SHORTWAVE RIDGING BECOMES
ESTABLISHED OVER THE SOUTHERN PLAINS. LOW LEVEL MOISTURE WILL
CONTINUE TO INCREASE THROUGH THE FIRST PART OF THE WEEKEND. A
LARGE UPPER TROUGH WILL BEGIN TO AFFECT OKLAHOMA AND NORTH TEXAS
LATE SATURDAY INTO SUNDAY. THIS WILL BRING A DECENT CHANCE OF
SCATTERED THUNDERSTORMS. MOST MODELS CONTINUE TO SUGGEST SOME
POTENTIAL FOR SEVERE STORMS ON SUNDAY...WHEN INSTABILITY AND WIND
SHEAR WILL BE MOST SUPPORTIVE. HOWEVER...THIS WILL NOT BE A
WIDESPREAD SEVERE WEATHER EVENT...AND HAIL AND WIND ARE THE ONLY
EXPECTED HAZARDS. THE UPPER TROUGH WILL MOVE EAST LATE SUNDAY INTO
MONDAY...BRINGING AN END TO SHOWERS AND STORMS BY MONDAY
AFTERNOON. HEADING INTO THE FIRST PART OF NEXT WEEK...WARM AND DRY
CONDITIONS WILL PREVAIL AS UPPER LEVEL RIDGING MOVES IN PLACE ONCE
AGAIN. LONG RANGE GUIDANCE CONTINUES TO SHOW A LARGE UPPER TROUGH
OVER THE WESTERN STATES. THIS ALONG WITH A DEEPENING LEE TROUGH
WILL INDUCE VERY WARM AND WINDY CONDITIONS BY WEDNESDAY. A WIND
ADVISORY MAY BE NEEDED AS WE NEAR THE MIDDLE OF NEXT WEEK. FIRE
DANGER WILL ALSO BECOME HEIGHTENED BOTH WEDNESDAY AND THURSDAY AS
A DRYLINE/PACIFIC FRONT MOVE THROUGH OKLAHOMA. WHILE THERE DOES
APPEAR TO BE SOME SEVERE THREAT BY LATE WEDNESDAY INTO
THURSDAY...MUCH UNCERTAINTY REMAINS IN TERMS OF TIMING/LOCATION
AND SUFFICIENT RETURN OF LOW LEVEL MOISTURE FOR MORE WIDESPREAD
SEVERE WEATHER. WILL MAINTAIN SLIGHT CHANCE POPS WED/THU UNTIL
MODEL AGREEMENT IMPROVES.
