ONLY A FEW TWEAKS WITH THE MORNING UPDATE. AREA OF SHOWERS IS
PASSING ACROSS THE NW EDGE OF THE FA...WITH JUST AND ISOLATED CELL
S OF KILN. ALTHOUGH THE FA IS IN THIS GENERAL LULL ATTM...
DESTABILIZATION WILL OCCUR WITH DAYTIME HEATING. H5 S/W AND SFC

AREA THIS EVENING AS SHORT WAVE ENERGY SHIFTS OFF TO OUR EAST.
MODELS ARE IN SOME DISAGREEMENT TO HOW MUCH WEAK MID LEVEL
RIDGING WILL BE ABLE TO BUILD UP FROM THE SOUTHWEST THROUGH THE
WEEKEND AND IT LOOKS LIKE WE MAY STAY IN MORE OF A NORTHWEST FLOW
PATTERN ALOFT. THERE ARE SOME SUGGESTIONS OF A FEW WEAK MID LEVEL
IMPULSES DROPPING DOWN ACROSS THE AREA THROUGH THE WEEKEND...BUT
TIMING AND PLACEMENT VARIES BY MODEL. DUE TO THE UNCERTAINTY AND

ACROSS THE AREA THROUGH MONDAY.  SOUTHERLY FLOW ON MONDAY WILL ALLOW
FOR THE WARMEST DAY OF THE LONG TERM WITH HIGH TEMPERATURES IN THE
MIDDLE 80S TO AROUND 90.

A COLD FRONT WILL APPROACH THE AREA MONDAY NIGHT AND MOVE THROUGH ON
TUESDAY.  MODELS ARE IN DECENT AGREEMENT WITH THIS FEATURE AND
THEREFORE INCREASED PRECIPITATION CHANCES INTO THE LIKELY CATEGORY.

KEEPING PRECIPITATION CHANCES IN THE FORECAST.  PRECIPITATION WILL
TAPER OFF BY WEDNESDAY EVENING.  HIGH PRESSURE AND COOLER
TEMPERATURES WILL WORK INTO THE REGION FOR THE REMAINDER OF THE LONG

DEVELOP. THE FORCING FROM THESE FEATURES WILL GRADUALLY PUSH E OF
THE TAFS BY 00Z. HAVE CARRIED TEMPOS WITH MVFR/IFR CONDITIONS IN
THE TSTM FOR THE FIRST 4 TO 5 HOURS OF THE PERIOD.
