DISCUSSION
KEY MESSAGE 1...
ANOTHER FAIRLY CLEAR NIGHT AS HIGH PRESSURE DEPARTS. FOG LOOKS
TO BE A BIT MORE CONFINED TO THE VALLEYS TONIGHT. OUR REGION
WILL BE BETWEEN LOW PRESSURE SYSTEMS SATURDAY. WITH SOUTHEAST
FLOW, CLOUDS WILL START TO INCREASE WITH ENOUGH MOISTURE TO
PRODUCE SOME SHOWERS SATURDAY NIGHT. THE MAIN COLD FRONTAL
PASSAGE LOOKS TO BE ANYWHERE FROM LATE MORNING TILL MID-
AFTERNOON. THIS WILL LIMIT THE OVERALL INSTABILITY DESPITE
MODEST SHEAR IN PLACE FOR ANY THUNDERSTORMS TO BE STRONG TO
SEVERE. HOWEVER, ENOUGH INSTABILITY LOOKS TO BE PRESENT FOR A
FEW THUNDERSTORMS TO DEVELOP IN ADDITION TO ANOTHER ROUND OF
SHOWERS DURING THIS TIMEFRAME. GENERAL QPF DOES NOT LOOK
SUFFICIENT EITHER FOR ANYTHING OTHER THAN LOCALIZED PONDING OF
WATER IN URBAN AREAS AND SOME RISES ON SMALL STREAMS.
TEMPERATURES LOOK TO BE FAIRLY TYPICAL WITH LOWS NEAR 60 AND
HIGHS NEAR 80 THROUGH THE WEEKEND THEN TREND COOLER EARLY NEXT
WEEK. THIS WILL BE DUE TO NORTHWEST FLOW UNDER A BROAD UPPER
LEVEL TROUGH. WEST TO NORTHWEST FLOW MAY RESULT IN SOME LAKE
EFFECT SHOWERS AS WELL ON BOTH MONDAY AND TUESDAY. TEMPERATURES
THEN REBOUND FOR THE REMAINDER OF THE WEEK. ENSEMBLE GUIDANCE IS
KEYING ON THURSDAY AND FRIDAY FOR THE NEXT CHANCE OF SHOWERS AND
THUNDERSTORMS.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
VFR CONDITIONS EXPECTED AT ALL TERMINALS THROUGH THE 18Z TAF
PERIOD. THE ONLY EXCEPTION WILL BE KELM, WHO IS EXPECTED TO
DEVELOP IFR/LIFR RESTRICTIONS BETWEEN 08Z AND 12Z TOMORROW, AND
COULD LAST A LITTLE BEYOND 12Z, BUT CONFIDENCE AS TOO LOW
CURRENTLY.
