352 AM CDT THU JUN 18 2009

.DISCUSSION...
MCS/MCV MOVING ACROSS NORTHEAST CWA AND SHOULD BE OUT BEFORE LONG
AND WE WILL AWAIT THE NEXT ROUND THIS AFTERNOON AND EVENING. TWO
MAIN FEATURES IN WATER VAPOR THAT WILL BE PLAYERS FOR NEXT 24HRS OR
SO WILL BE THE SOUTHERN STREAM TROF THAT WILL BE SHEARING APART AND
NORTHERN STREAM TROF CROSSING MOVING TOWARD THE NORTHERN ROCKIES
ATTM. SEEMS TO BE A DISTINCT SPIN SHOWING UP IN SE UTAH WHICH SHOULD
RIDE THE MODERATELY FAST SW FLOW INTO HIGH PLAINS THIS AFTERNOON AND
LOOKS TO INTERACT WITH SFC BOUNDARY/WEAK COLD FRONT THAT WILL BE
MOVING SE INTO NEB. LARGE SCALE ASCENT FROM THIS WAVE...APPROACHING
ROCKIES TROF AND FAVORABLE UPPER JET MAXIMA. FAIRLY DRY AIR BEHIND
FRONT WILL LIMIT STRONGER LLVL INSTABILITY WITH MOISTURE POOLING
AHEAD OF FRONT IN EASTERN CWA MAY BE AROUND 2500-3000 J/KG. STRONG
SHEAR ALOFT SHOULD BE SUPPORTIVE OF A FEW SUPERCELLS BUT OVERALL
THREAT SEEMS TO BE LESS THAN WED WITHOUT THE STRONGLY BACKED LLVL
WINDS...WHICH SHOULD BE WELL NORTHEAST OF CWA AHEAD OF WARM FRONT.
UPPER TROF WILL PUSH ACROSS CWA OVERNIGHT AND EXPECT CONVECTION TO
HOLD IN THROUGH EARLY MORNING HOURS SIMILAR TO CURRENT CONDITIONS
BUT SEVERE THREAT LOOKS TO BE FAIRLY SMALL. DID MAKE SOME TWEAKS TO
POPS FOR THIS ANTICIPATED SCENARIO OVER NEXT 24 HOURS. BEYOND THIS
QUIET WX SHOULD RETURN FOR FRIDAY AS RIDGE BUILD IN OVHD AND LARGER
TROF BEGINS TO SWING INTO WESTERN CONUS. LOOKS TO BE STRONG MOISTURE
FEED FROM SUBTROPICS AND WESTERN GULF SO ACTIVE WEATHER LIKELY TO
RETURN FOR THE WEEKEND. TEMPS THROUGH NEXT 5 DAYS GENERALLY AT OR
ABOVE SEASONAL LEVELS.
