FRONT SAT. UNTIL THAT FRONT MOVES ACROSS...WE WILL REMAIN IN AN
OVERRUNING PATTERN...TRANSITION TO A SHOWERY NATURE FRIDAY NIGHT.
THE FRONT SHOULD BE OUT OF OUR CWA SAT EVENING.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
FOR THE FORECAST HAVE MADE USE OF THE HPC GUIDANCE WHICH FOLLOWS
BEST WITH THE 00Z ECMWF SOLUTION REGARDING BOTH PRECIPITATION
TIMING AND CHANCES AND TEMPERATURES. HOWEVER MADE SOME TWEAKS TO
SAT NIGHT/SUNDAY TO REFLECT A BIT MORE PROGRESSIVE NATURE TO
LATEST MODEL RUNS...WITH SHRA EXITING A BIT FASTER SAT NIGHT AT
THIS POINT.

BEHIND THE FRONT POPS GRADUALLY TAPER OFF BUT NOT TO ZERO AS WE
WILL STILL HAVE THE UPPER LOW PASSING NORTH OF THE AREA AND
