.SYNOPSIS...
LOW PRESSURE WILL TRACK ACROSS THE AREA THIS AFTERNOON, RESULTING IN
SCATTERED SHOWERS AND THUNDERSTORMS, PRIMARILY THIS AFTERNOON.
SOME OF THE SHOWERS WILL BE HEAVY AT TIMES. SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS ARE EXPECTED AGAIN ON MONDAY AS A SECONDARY

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
LOW PRESSURE IS TRACKING TO THE NORTH OF THE CWA, WITH A WARM AND
COLD FRONT OVER THE CWA ATTM. THIS, TOGETHER WITH PWATS UP TO 2
INCHES IS CAUSING SOME HEAVY RAIN IN THE AREA. THIS AREA OF RAIN
WILL MOVE EASTWARDS THROUGH THE EVENING HOURS. WITH SOME CLEARING
BEHIND THE COLD FRONT, DAYTIME HEATING HAS CAUSE SOME ISOLATED
STORMS TO DEVELOP. THE 0-6KM BULK SHEAR COMBINED WITH CAPE OF
AROUND 1000J MAY ALLOW AN ISOLATED SEVERE STORM DEVELOP, AND
ACTUALLY ALLOWED ONE TO DEVELOP TO THE NORTH OF THE CWA THIS
AFTERNOON, WHICH MEANS THEY ARE POSSIBLE.

BEHIND THE FRONT AND WITH THE LOSS OF DAYTIME HEATING, STORMS
SHOULD BEGIN TO SUBSIDE. THERE WILL STILL BE SOME POSSIBLE SHOWERS
THOUGH THROUGH THE NIGHT. ALSO, ANY CLEARING TONIGHT WILL LIKELY
RESULT IN SOME DENSE FOG AROUND THE AREA.

&&

MONDAY...SECONDARY TROF WILL PASS THROUGH THE REGION UNDER
NORTHWEST FLOW. DUE TO DRIER AIR ADVECTING OVER THE AREA ALONG

FOR SHOWERS WILL DECREASE IN THE NRN CWA AS BOUNDARY PASSES
THROUGH. HIGHS WILL RANGE FROM THE UPPER 70S TO AROUND 80 AND WITH
DEW POINTS IN THE LOWER 60S IT WILL FEEL MORE COMFORTABLE.

MONDAY NIGHT...BRIEF UPPER LEVEL RIDGING ALONG WITH SFC HIGH PRES
NOSING DOWN FROM THE UPPER GREAT LAKES WILL PROVIDE A DRY PERIOD

VALLEY AND PASS SOUTH OF THE REGION DURING THE EVENING. LATE
TUESDAY NIGHT THE NEXT SFC TROF WILL APPROACH THE REGION BY EARLY
WEDNESDAY MORNING. WILL CONTINUE WITH LOW CHC POPS FOR THESE
FEATURES TUESDAY AFTERNOON THROUGH TUESDAY NIGHT.

TROF IN PLACE ACROSS THE NORTHEAST U.S. SHORTWAVES MOVING THRU THE
MEAN FLOW WILL BRING CHCS FOR SHRA/TSRA...WITH EXACT TIMING FOR BEST
PERIODS OF PRECIP DIFFICULT THIS FAR OUT.  MODELS ALSO CONTINUE TO

DEGREES BELOW AVG FOR EARLY/MID AUGUST.
