TNT THRU THU NIGHT...

TSTMS ARE ONGOING ATTM OVER OUR WRN COUNTIES AND EXPECTING THESE TO
MOVE TO THE ENE AROUND 15 MPH.  HAVE KEPT A CHANCE OF SHOWERS AND
TSTMS OVERNIGHT GIVEN THAT RADAR IS BEGINNING TO FILL OUT PRETTY
NICELY AND WITH LOTS OF INSTABILITY AVAILABLE THINK THESE WILL TAKE
LONGER TO DISSIPATE.  LOTS OF CLOUDS AND SOME WIND OVERNIGHT WILL
KEEP TEMPS FROM DROPPING TOO MUCH.  MAX TEMPS TOMORROW COULD BE A
COUPLE OF DEGREES COOLER THAN TODAY DUE TO LOTS OF CLOUDS AROUND THE
AREA...BUT TEMPS SHOULD REACH 90 AND WITH VERY MOIST AIR MASS IN
PLACE...HEAT INDICES COULD APPROACH ADVISORY CRITERIA. SO THIS HAS
TO BE EVALUATED ONCE AGAIN. SHORTWAVE TROUGH ROTATING AROUND GREAT
LKS TROUGH WILL CONTINUE TO SHIFT TO THE EAST AND FORCE A COLD FRONT
INTO OUR AREA.  FRONT WILL BEGIN TO APPROACH OUR NRN COUNTIES BY 06Z
FRI AND HAVE RAISED POPS TO LIKELY ON THURS NIGHT.  SINCE COLD FRONT
WILL NOT CLEAR OUR CWA UNTIL AFTER 12Z FRI...AND WITH PRECIP STILL
AROUND THE AREA...MIN TEMPS WILL LIKELY BOTTOM OUT ONLY INTO THE LOW
70S.  DRIER AIR WORKS IN BEHIND THE FRONT WITH A NICE WEEKEND ON TAP.
