Area forecast discussion, Jul 13, 3:33 PM CDT, 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 333 PM CDT FRI JUL 13 2012 .DISCUSSION... ORGANIZED CLUSTER OF SHOWERS AND THUNDERSTORMS SNEAKING UP ON OK/KS BORDER PRESENTLY CONTINUES TO SHOW TENDENCY OF DEVELOPMENT ON THE WESTERN FLANK AS THE WHOLE COMPLEX DIVES SOUTH. THESE STORMS SHOULD CONTINUE TO PUSH SOUTH THIS AFTERNOON THROUGH AXIS OF HIGHEST INSTABILITY ORIENTED NEAR I-44. A LIMITED THREAT WILL EXIST OF DAMAGING DOWNBURSTS WITH DCAPES AROUND 1000 J/KG PRESENT THROUGHOUT EASTERN OK. OTHER TERRAIN FORCED STORMS WILL REMAIN POSSIBLE THROUGH THE LATE AFTERNOON AS WELL. WILL NEED TO INCLUDE A PRE FIRST PERIOD WITH HIGH POPS ACROSS SOME OF NE OKLAHOMA LATE THIS AFTERNOON. TREND SHOULD BE FOR THIS ACTIVITY TO DECREASE AFTER 00Z BUT THERE IS A SHOT AT LEAST OF SOME MAKING IT INTO SE OKLAHOMA AS WELL. MOST IF NOT ALL SHOULD BE GONE AFTER 06Z. UPPER LEVEL LOW ALONG THE TX/LA GULF COAST EXPECTED TO SLIDE WEST THE NEXT COUPLE OF DAYS AND KEEP SMALL CHANCES OF AFTERNOON/EVENING THUNDERSTORMS MAINLY ACROSS SOUTHERN AND EASTERN SECTIONS. THIS ALSO LEADS TO A MODEST BREAK DOWN IN THE UPPER RIDGE AND WILL KNOCK A DEGREE OR TWO OFF AFTERNOON TEMPS IN MOST AREAS. BEYOND THAT STRONG RIDGE EXPECTED TO BUILD BACK OVER THE AREA WITH TRIPLE DIGIT HEAT BOOMING WIDESPREAD NEXT WEEK. OUTSIDE OF URBAN AREAS THE OVERNIGHT LOWS SHOULD REMAIN BELOW 75 THROUGH MID WEEK BUT BY LATE NEXT WEEK HEADLINES MAY BE NEEDED...AND RECENT BIAS ADJUSTMENT TO MEX GUIDANCE SUGGESTS HIGHS WELL OVER 100 BY END OF THE WEEK. && .PRELIMINARY POINT TEMPS/POPS...
