AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC 758 PM EDT SUN SEP 1 2013 .SYNOPSIS... A LOW PRESSURE SYSTEM OVER LAKE SUPERIOR WILL MOVE EAST INTO SOUTHERN QUEBEC EARLY THIS WEEK. A COLD FRONT ASSOCIATED WITH THIS LOW WILL MOVE THROUGH THE MID-ATLANTIC MONDAY NIGHT AND TUESDAY. A REINFORCING COLD FRONT MOVES THROUGH ON THURSDAY... WITH HIGH PRESSURE BUILDING IN FOR THE END OF THE WEEK. && .NEAR TERM /THROUGH MONDAY/... WATER VAPOR IMAGERY INDICATES SHORTWAVE EXTENDS FROM CENTRAL PA TO CENTRAL WV. CONVECTION AHEAD OF THIS SHORTWAVE IS FOCUSED ON THE EASTERN WV PANHANDLE AND NRN MD. WITH LITTLE STEERING FLOW AND MOIST AIR...THESE STORMS HAVE BEEN MOVING SLOWLY AND DROPPING SIGNIFICANT AMOUNTS OF RAINFALL. LOCALIZED FLOODING/FLASH FLOODING WILL BE POSSIBLE WITH ANY STORMS. ISOLATED SEVERE THREAT CONTINUES AS WELL...PRIMARILY FOR DAMAGING WINDS. CONVECTION IS EXPECTED TO DIMINISH THROUGH THE EVENING HOURS AS THE BOUNDARY LAYER BECOMES MORE STABLE. SHORTWAVE WILL MOVE ACROSS THE FORECAST AREA TONIGHT. MODELS CONTINUE TO INDICATE POTENTIAL OF SHOWERS AND A FEW TSTMS REDEVELOPING...SO PERSISTING WITH FCST THAT RAISES POPS BACK TO CHANCE CATEGORY ROUGHLY NORTH OF US HIGHWAY 50. MODEL SOUNDINGS SHOW PLENTY OF MID- LEVEL DRYING WITH LOW- LEVEL MOISTURE AND LIGHT WINDS...SO FOG FORMATION IS EXPECTED AGAIN...ESPECIALLY WHERE LOW-LEVEL MOISTURE IS ENHANCED FROM SUNDAY AFTERNOON/EVENING CONVECTION. FOR LABOR DAY...MODELS SHOW NOT MUCH IN THE WAY OF UPPER DISTURBANCES...WITH MOST OF THE WEAK WAVES PASSING TO THE NORTH OF THE AREA. MODEL POPS ARE SURPRISINGLY LOW /20-ISH/ IN MOST AREAS. JUST NOT WILLING TO BUY THAT...BUT WILL BACK DOWN FROM LIKELY POPS TO HIGH-END CHANCE. SPC MAINTAINS A 5 PERCENT SEVERE RISK IN OUR NORTHERN COUNTIES...AND WILL RETAIN THE MENTION IN THE HWO. SBCAPE AND PWATS ARE SIMILAR TO TODAY WITH A BIT MORE SHEAR. && .SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/... AS MENTIONED IN THE NEAR TERM SECTION...POPS IN THIS FORECAST PACKAGE ARE WELL ABOVE ALL GUIDANCE THROUGH MONDAY EVENING AS PCPN SHOULD DEVELOP ALONG/AHEAD OF THE SFC TROUGH AND SFC FRONT...AND PUSH THROUGH THE METRO AREAS. LARGE HAIL AND DAMAGING WINDS REMAIN THREATS THROUGH THE EVENING...ESPECIALLY NORTH AND EAST. THE REAL FORECAST QUESTION IS HOW FAR DOES THE FRONT MAKE IT GIVEN THAT THE LONGWAVE TROUGH AXIS LAGS BEHIND. I HAVE CONTINUED THE TREND OF INCREASING POPS ON TUESDAY...IN FACT THIS MAY BE THE MOST CERTAIN I AM OF PRECIP OCCURRING IN ANY GIVEN LOCATION FOR THE ENTIRE FORECAST PERIOD...LIKELY SOUTH AND EAST OF I-95. ALSO...WITH LOW- LEVEL MOISTURE SLOW TO DROP...COULD EVEN SEE SOME UPSLOPE SHOWERS ON THE ALLEGHENY FRONT MONDAY NIGHT INTO TUESDAY MORNING. TEMPS RETURN TO SEASONABLE BY TUESDAY AFTERNOON. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... DRY CONDITIONS AS HIGH PRESSURE DOMINATES THROUGH FRIDAY. WEAK SFC TROUGH DROPS SOUTH INTO THE CWA WEDNESDAY NIGHT...PUSHING SOUTH THURSDAY. PROBABLY JUST SOME MID LEVEL CLOUDS ASSOCIATED WITH THIS DISTURBANCE. MAX TEMPS CLOSE TO NORMAL...LOW 80S WED-FRI. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... TSTM ACTIVITY IS FOCUSED ON KMRB EARLY THIS EVENING. ONCE THIS ACTIVITY MOVES OUT OR WEAKENS...EXPECTING GENERALLY DRY/VFR LATE EVENING AND EARLY OVERNIGHT HOURS. PATCHY FOG POSSIBLE AGAIN LATE TNGT...ESPECIALLY AT THE FOG-PRONE LOCATIONS AT CHO AND MRB. MVFR VSBYS ALSO PSBL AT THE BALTIMORE/WASHINGTON TERMINALS EARLY MONDAY MORNING. THUNDERSTORMS INCREASE MONDAY AFTERNOON/CONTINUE THROUGH THE NIGHT AS A COLD FRONT DRIFTS EAST ACROSS THE TERMINALS. SLY FLOW AROUND 10 KT...THOUGH DAMAGING WINDS ARE POSSIBLE IN THUNDERSTORMS. HIGH PRESSURE THEN BUILDS TUESDAY AND DOMINATES REST OF THE WORK WEEK WITH VFR CONDITIONS. && .MARINE... SLY WINDS AROUND 10 KTS...WITH POSSIBLE GUSTS AROUND 15 KTS...WILL CONTINUE THROUGH TONIGHT. SCTD STORMS POSSIBLE OVER THE WATERS BUT CHANCES ARE ACTUALLY LOWER THAN FURTHER WEST. STILL... LOCALLY STRONG WINDS WITH THESE STORMS COULD BECOME HAZARDOUS TO MARINERS AND HOLIDAY BOATERS...SO STAY WEATHER AWARE. COULD SEE SOME WIND GUSTS TO SMALL CRAFT ADVISORY CRITERIA IN THE TANGIER SOUND AGAIN TONIGHT...BUT DID NOT ISSUE AN ADVISORY YET. SIMILAR FLOW CONTINUES AHEAD OF A COLD FRONT ACROSS THE WATERS MONDAY. SPECIAL MARINE WARNINGS POSSIBLE FROM THUNDERSTORMS LATE MONDAY AFTERNOON THROUGH THE NIGHT. FLOW BECOMES NWLY BY TUESDAY EVENING...SOME CHANNELING GUSTS MAY APPROACH 18 KT. VARIABLE FLOW AND HIGH PRESSURE WEDNESDAY THROUGH FRIDAY. && .LWX WATCHES/WARNINGS/ADVISORIES... DC...NONE. MD...NONE.
