HEAVY RAIN CONTINUES TO BE THE MAIN THREAT FROM STRONGER STORMS WITH MOST LIKELY AREA FOR THIS BEING EAST OF THE MTNS INTO THIS EVENING. ANY FLOODING THAT MIGHT OCCUR SHOULD REMAIN RATHER LOCALIZED. SOME HAIL THREAT STILL THERE AS WELL THOUGH UPPER SUPPORT NOT ALL THAT GREAT. ACTIVITY WILL DECREASE OVERNIGHT THOUGH SOME MAY HANG ON OVER NORTHEAST PARTS OF THE CWA THROUGH THE NIGHT. SIMILAR SCENARIO EXPECTED FOR SATURDAY AS SFC UPSLOPE FLOW BEHIND A WEAK SFC FRONT THAT WILL PASS ACROSS DURING THE DAY ALLOWS FOR REDEVELOPMENT OF CONVECTION. INSTABILITY NOT PROGGED TO BE AS GREAT THOUGH SO ACTIVITY LIKELY TO BE MORE SHOWERY IN NATURE. TEMPS JUST A LITTLE COOLER OVER THE PLAINS. ACTIVITY WILL DIE OUT SAT EVENING. A STRONGER FRONT WILL THEN PUSH SOUTH ACROSS THE CWA SUNDAY WITH SCTD SHOWERS AND A FEW STORMS ONCE AGAIN. .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY) ISSUED AT 312 PM MDT FRI JUL 11 2014 A DEEP UPPER LEVEL TROUGH WILL MAINTAIN HOLD OVER THE EASTERN CONUS THROUGH THE EXTENDED PERIOD...WITH A STRONG UPPER HIGH SITUATED OVER THE WEST.

WILL SEE A FEW SHOWERS/TSTORMS OVER THE MOUNTAINS ON MONDAY WITH THE FRONT...WITH MINIMAL CHANCE FOR CONVECTION FURTHER EAST IN THE MORE STABLE POST-FRONTAL ENVIRONMENT. A RATHER POTENT SHORTWAVE WILL ROUND THE TOP OF THE RIDGE AND WILL MOVE SOUTHEAST ACROSS THE HIGH PLAINS ON TUESDAY AND TUESDAY NIGHT. THIS WAVE WILL CARRY ALONG PLENTIFUL PACIFIC MOISTURE...THUS WILL SEE A MUCH BETTER CHANCE FOR CONVECTION ON TUESDAY WITH THE UPPER WAVE AND UPSLOPE FORCING. GFS IS PRODUCING BULK SHEAR VALUES OF 40 TO 50 KTS OVER THE CWA WITH THE JET OVERHEAD SO WOULD NOT BE SURPRISED IF A FEW STORMS ORGANIZE TO BECOME STRONG/SEVERE. BOTH GFS AND ECMWF KEEP SHOWERS/STORMS ONGOING THROUGH THE NIGHT...WITH ACTIVITY GRADUALLY SHIFTING WEST TOWARD THE MOUNTAINS FOR WEDNESDAY.
