DISCUSSION
WEATHER PATTERN OVERVIEW:
MONDAY WILL BEGIN WITH QUIET WEATHER CONDITIONS, BUT A TROUGH TO
THE WEST WILL QUICKLY MOVE EASTWARD WITH INCREASING SHOWERS AND
THUNDERSTORMS OVERNIGHT INTO EARLY TUESDAY MORNING. HREF GUIDANCE
SHOWS THE BEST SUPPORT FOR THIS AFTER ABOUT 3AM AND ESPECIALLY
ACROSS THE EASTERN ZONES. THIS IS WHERE THE BEST INSTABILITY AND
SHEAR PROFILES MAY ALSO SUPPORT AN ISOLATED STRONG STORM.
THE UPPER LOW WILL CONTINUE TO REMAIN PARKED OVER THE REGION
THROUGH THE WEEK.THIS WILL CONTINUE TO GENERATE FREQUENT CHANCES
FOR SHOWERS AND THUNDERSTORMS. IN ADDITION, THIS PATTERN WILL TEND
TO MAINTAIN SEASONABLY COOL TEMPERATURES EACH DAY THROUGH THE
PERIOD.
FORECAST CONFIDENCE & DEVIATIONS:
NBM WAS USED FOR THE FORECAST PERIOD WHICH HANDLED LARGE SCALE
TRENDS WELL. CONFIDENCE IS ABOVE AVERAGE ON THE OVERALL DEPICTION
THIS WEEK FOR SEASONABLY COOL CONDITIONS AND FREQUENT CHANCES FOR
SHOWERS AND THUNDERSTORMS. CONFIDENCE IS A BIT MORE MODERATE ON
EXACT TIMING AND PLACEMENT OF THE STORMS GIVEN UNCERTAINTIES
SURROUNDING MESOSCALE DETAILS AT LARGER TIME SCALES. AS THESE
DETAILS BECOME BETTER RESOLVED, ADJUSTMENTS FOR NEAR TERM POPS MAY
MAKE BETTER SENSE OVER THE COURSE OF THE WEEK.
