Area forecast discussion, Aug 10, 9:00 AM EST, 4 hours 20 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAY ME
1000 AM EDT SUN AUG 10 2008
.SYNOPSIS...
LOW PRESSURE CENTERED NEAR LAKE HURON WILL DIVE SOUTHEAST AND
REFORM ALONG THE NEW JERSEY COAST EARLY MONDAY MORNING. THIS LOW
WILL MOVE THROUGH THE GULF OF MAINE TUESDAY AND INTO THE CANADIAN
MARITIMES WHERE IT WILL REMAIN NEARLY STATIONARY INTO FRIDAY. HIGH
PRESSURE WILL CREST OVER THE AREA FRIDAY AND SATURDAY. LOW
PRESSURE WILL APPROACH THE AREA SUNDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
FORECAST PACKAGE IS IN PRETTY GOOD SHAPE THIS MORNING. TWEAKED SKY
COVER A LITTLE BIT TO ACCOUNT FOR SLOWLY ERODING FOG AND STRATUS.
NEXT FOCUS FOR THE DAY WILL BE ON SEVERE WEATHER POTENTIAL. GFS IS
MUCH MORE AGGRESSIVE WITH CONVECTIVE POTENTIAL TODAY THAN THE NAM.
NAM IS INDICATING A VERY STRONG 700MB CAP DEVELOPING BY MID-
DAY...INHIBITING MUCH OF THE CONVECTIVE POTENTIAL. GFS NOT SHOWING
THIS FEATURE AT ALL. THE RESULT IS SBCAPE VALUES APPROACHING 2000
J/KG ACROSS MOST OF THE REGION THIS AFTERNOON. ALMOST NO SHEAR IN
PLACE...SO PRIMARY THREAT SHOULD BE HEAVY RAIN AND SMALL HAIL. OF
THE TWO...HEAVY RAIN IS DEFINITELY THE PRIMARY CONCERN. LOCATIONS
OVER NH ARE ALREADY SATURATED AND 1 TO 2 INCHES OF RAIN COULD
BEGIN TO POSE SOME MAJOR PROBLEMS. ADDITIONALLY WEAK UPPER LEVEL
FLOW WILL ONLY ALLOW AROUND 15KTS FOR STORM MOTION. THE SLOW
MOVING STORMS WILL ONLY MAKE THINGS WORSE. DECENT LINE ALREADY IN
PLACE OVER CENTRAL/EASTERN NY STATE. COMPARING THE ALY AND GYX 12Z
SOUNDINGS SHOWS DISTINCTLY DIFFERENT CONVECTIVE ENVIRONMENTS.
EXPECT ISOLATED SEVERE ACTIVITY OVER NH AND PERHAPS WESTERN ME
THIS AFTERNOON. THE TRULY ORGANIZED CONVECTION SHOULD REMAIN
PRIMARILY TO OUR WEST AND SOUTH.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
MODELS HAVE SHIFTED FURTHER SOUTH WITH THE 500 MB LOW THIS
RUN...WHICH HAS ALSO SHIFTED THE HEAVIES QPF SOUTH AND WEST. MAIN
DYNAMIC CAUSE FOR PRECIP SEEMS TO BE AN UPPER LEVEL DIFLUENT
ZONE...WHICH CAN CAUSE CONVECTION TO LINGER OVERNIGHT.
NAM/GFS/UKMET/GEM BLEND ALL KEEP HEAVIEST PRECIP SOUTH AND
WEST...THOUGH FEEL THERE STILL IS A LITTLE WIGGLE ROOM ON THE
TRACK OF A 500 MB LOW. FOR NOW...EXPECT SOUTHERN NEW HAMPSHIRE
WILL GET CLIPPED BY THE REMAINDER OF A CONVECTIVE COMPLEX LATE
TONIGHT. DO NOT HAVE ENOUGH CONFIDENCE IN QPFS OVER AN INCH TO
EXTEND ANY SORT OF WATCH FOR TONIGHT BASED ON THIS...AS THE
DYNAMICS COULD JUST AS EASILY SLIP JUST SOUTH OF OUR CWA.
OTHERWISE...USE NAM/GFS BLEND ON LOWS. EXPECT STRATUS TO MOVE IN
AGAIN...WITH MOSTLY CLOUDY SKIES AND PATCHY FOG.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
NAM/GFS/ECMWF ALL SIMILAR IN BRINGING GREAT LAKES LOW SOUTHEAST
TO THE JERSEY COAST AND THEN MOVING IT NE THROUGH THE GULF OF
MAINE. SFC LOW WILL THEN BECOME NEARLY STATIONARY OVER THE
CANADIAN MARITIMES. MODELS ALSO MOVE A COUPLE OF SYSTEMS TO OUR
SOUTH DURING THE WEEK.
MONDAY LOOKS LIKE A DREARY SHOWERY DAY WITH HIGH TEMPS 10 DEGREES
OR MORE BELOW NORMAL. RAIN/SHOWERS MAY LINGER INTO TUE MORNING
WITH ECMWF/NAM BEING THE SLOWER OF THE MODEL TO MOVE THE SFC LOW NE
INTO CANADA.
WE WILL CONTINUE TO BE IN A CYCLONIC CIRCULATION WITH UPPER LVL
ENERGY ALOFT EXPECT TO SEE SHOWERS EACH AFTN WITH THE CHC OF
THUNDER. HOWEVER TEMPERATURES SHOULD REACH NEAR THE NORMAL HIGHS
FOR THE TIME OF YEAR.
&&
.AVIATION /14Z SUNDAY THROUGH THURSDAY/...
SHORT TERM...RADATION FOG TO CAUSE WIDESPREAD VLIFR CONDITIONS
THROUGH 12Z...WITH FOG BURNING OFF BETWEEN 12Z AND 15Z. EXPECT
STRATUS MAY LINGER LONGER AT PWM-PSM...PERHAPS ALL DAY. EXPECT
IFR IN STRATUS TONIGHT...WITH VSBY HIGHER AS IT WILL BE MORE
ADVECTION FOG THAN THE RADIATION FOG WE/RE SEEING THIS MORNING.
ALSO...FOR THIS AFTERNOON...EXPECT SCATTERED THUNDERSTORMS...WITH STRONGER
STORMS PERHAPS PRODUCING SMALL HAIL.
LONG TERM...EXPECT MOSTLY MVFR/IFR MONDAY THROUGH TUESDAY MORNING
IN SHOWERS AND FOG. TUESDAY EXPECT IMPROVEMENT TO VFR WITH BRIEF MVFR
CONDITIONS IN THE AFTN IN -SHRA/-TSRA. TUESDAY NIGHT AND WED NIGHT EXPECT
IFR IN FOG. WED AND THU EXPECT VFR EXCEPT IN -SHRA.
&&
.MARINE...
SHORT TERM...WINDS VERY LIGHT TODAY AND TONIGHT...WITH MAIN ISSUE
DENSE FOG EARLY THIS MORNING.
LONG TERM...COULD APPROACH SCA WINDS AND SEAS BRIEFLY LATE MON
EARLY TUES AS SFC LOW DEVELOPS AN LIFTS NE.
