AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
1013 AM EDT SUN JUL 15 2007

.SYNOPSIS...
COLD FRONT WILL CROSS THE REGION THIS AFTERNOON/EVENING...
FOLLOWED BY A WEAK AREA OF HIGH PRESSURE LATER TONIGHT AND
MONDAY. ANOTHER BOUNDARY WILL TRANSIT THE REGION MONDAY NIGHT...
THOUGH MODELS NOT IN AGREEMENT ABOUT POSITION/TIMING. PATTERN OF
WEAK DISTURBANCES MOVING THROUGH REGION IN FAST FLOW CONTINUES
INTO THE WEEKEND. THERE ALSO CONTINUES TO BE MUCH UNCERTAINTY IN
THE TIMING AND LOCATION OF THESE SYSTEMS.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE FORECAST PROBLEM FOR TODAY WILL BE THUNDERSTORMS.

THE LOW CLOUDS AND FOG IS LIFTING...ALLOWING CLEARING TO OCCUR
ACROSS SOUTHEAST NEW HAMPSHIRE AND SOUTHWEST MAINE. AN INITIAL
LINE OF CONVECTIVE LOOKING RAIN IS CROSSING NORTHERN AND CENTRAL
NEW HAMPSHIRE...WITH DEEPER CLOUDS ACROSS THE MOUNTAINS.

IT APPEARS AS THOUGH THE MOUNTAINS WILL STAY IN THE FRONTAL CLOUD
BAND AREA TODAY...AND THE CONVECTIVE POTENTIAL HERE IS SOMEWHAT
LIMITED. FURTHER SOUTH...AFTER THE PASSAGE OF THE INITIAL RAIN
BAND...THE AIRMASS WILL GET A CHANCE TO DESTABILIZE AGAIN. THIS
SHOULD ALLOW A MODERATE UNSTABLE AIRMASS TO MATERIALIZE...WITH A
GOOD SHEAR PROFILE. THIS AREA SHOULD EVENTUALLY COVER THE FOOTHILLS
AND INTERIOR PORTIONS OF WESTERN MAINE AND INTERIOR NEW HAMPSHIRE
THIS AFTERNOON.

MODEL SOUNDINGS SHOW LITTLE IN THE WAY OF CAPPING AND A GOOD WIND
PROFILE WITH TURNING IN THE LOWER LEVELS. THE INSTABILITY MAY
NOT BE PRESENT FOR SUPER CELL DEVELOPMENT...BUT MULTIPLE STRUCTURE
IS LIKELY WITH LINE SEGMENTS AND BOW STRUCTURES CAPABLE OF PRODUCING
WIND DAMAGE. THE WORDING FOR THESE AREAS HAS BEEN ENHANCED TO
INCLUDE DAMAGING WINDS.

CLOSER TO THE COAST...THE AIRMASS LOOKS CAPPED IN THE LOWER LEVELS
(AS SEEN ON THE GYX 12Z SOUNDING). IT APPEARS TO BE DUE PRIMARILY
TO THE MARINE LAYER IN PLACE THIS MORNING. THIS COULD LIMIT THE
CONVECTIVE POTENTIAL TO SOME DEGREE...AND MODEL SOUNDINGS SHOW
THIS FEATURE PERSISTING INTO THE AFTERNOON. WILL CONTINUE WITH THE
PREVIOUS ENHANCED WORDING IN THESE AREAS.

THE CONVECTION SHOULD BE LIMITED THIS MORNING...INCREASING THIS
AFTERNOON WITH INCREASED INSTABILITY. A SURFACE TROUGH ACROSS
EAST CENTRAL NEW YORK WILL SERVE AS A FOCUS FOR THE CONVECTION...
WITH THE PRIME THUNDERSTORM ACTIVITY EXPECTED BETWEEN 17Z AND 22Z
THUS AFTERNOON. WIND DAMAGE IS THE MAIN THREAT...WITH LARGE HAIL
PROBABLY BEING LIMITED TO SUPER CELLS OR MINI SUPER CELLS...AS THE
WET BULB ZERO VALUES ARE HIGH.

CLEANED UP THE SKY COVER FOR THIS AFTERNOON...BUT THE REMAINDER OF
THE NEAR TERM REMAINS INTACT.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
FRONT MOVES OFFSHORE THIS EVENING FOLLOWED BY CLEARING TREND
OVERNIGHT AS WEAK HIGH PRESSURE WORKS ITS WAY ACROSS FORECAST
AREA. HAVE ONCE AGAIN USED BLEND OF CURRENT FORECAST/ MAV/MET DATA
FOR TEMPERATURES AND BLEND OF CURRENT FORECAST/MAV DATA FOR POPS.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
EASTERN TROUGH REMAINS IN TACT THROUGH THE LONG RANGE PERIOD. WEAK
IMPULSES WILL CONTINUE TO CIRCULATE AROUND THIS TROUGH THROUGHOUT
THE UPCOMING WEEK.

A VERY WEAK FRONT PASSES THROUGH THE REGION FROM MONDAY AFTERNOON
THROUGH MONDAY NIGHT. MODELS HAVE BEEN GETTING FASTER WITH THIS
FRONT AND BECOMING WEAKER SO NOT EXPECTING MUCH IN THE WAY OF
PRECIPITATION WITH THE FRONT. GFS SHOWING WEAK
DISTURBANCE...RATHER SHEARED OUT...MOVING EAST ALONG FRONTAL
BOUNDARY OVERNIGHT MONDAY NIGHT. GENERALLY EXPECTING ONLY WIDELY
SCATTERED SHOWERS/ISOLATED TSTMS WITH FRONT WITH GREATEST THREAT
DURING OVERNIGHT PERIOD IN SOUTHERN AREAS AS DISTURBANCE PASSES
EAST.

NAM QUITE DIFFERENT FROM OTHER MODELS...SO HAVE DISCOUNTED
SIGNIFICANT PRECIP EVENT THAT IT IS ADVERTISING FOR TUESDAY.
PREFER GFS SOLUTION WHICH BRINGS RIDGE ACROSS AREA DURING DAY.

MODELS CONTINUE TO SHOW A SERIES OF DISTURBANCES MOVING AROUND THE
UPPER TROUGH. TIMING AND IMPACT OF THESE DISTURBANCES IS UNCERTAIN
AT THIS TIME.

&&

.AVIATION /14Z SUNDAY THROUGH THURSDAY/...
THE LAST OF THE MORNING STRATUS AND FOG IS LIFTING...AND SHOULD BE
GONE BY 15Z. AFTER THIS...VFR CONDITIONS ARE EXPECTED TO PREVAIL.
SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED IN THE TERMINAL
LOCATIONS...AND ARE BEING ADDED TO THE FORECAST AS NEEDED THIS
MORNING. DEPENDING ON THE STRENGTH OF THE CONVECTION...MAY NEED TO
ADD WIND INFORMATION WITH THUNDERSTORMS THIS AFTERNOON.

BECOMING MOSTLY VFR TONIGHT THOUGH SOME MVFR IN PATCHY FOG EXPECTED.
VFR CONDITIONS EXPECTED MONDAY...ALTHOUGH SOME MVFR CONDITIONS POSSIBLE
IN WIDELY SCATTERED SHOWERS/ISOLATED THUNDERSTORMS MOVING
SOUTHEAST FROM MOUNTAINS TO COAST FROM MONDAY AFTERNOON THROUGH
TUESDAY MORNING. WEAK DISTURBANCES WILL IMPACT REGION PERIODICALLY
THROUGH THURSDAY...HOWEVER STRENGTH AND TIMING OF THESE
DISTURBANCES IS UNCERTAIN AT THIS TIME.

&

.MARINE...
SHORT TERM...WINDS ARE ALREADY STARTING TO INCREASE WITH THE
GRADIENT AND PASSAGE OF THE SURFACE WARM FRONT. THE DEPTH OF THE
MIXED LAYER IS STILL VERY LOW...AND THE STRONGEST WINDS WILL BE
OBSERVED AT THE C MAN STATIONS. WILL CONTINUE TO ADVERTISE NEAR
SMALL CRAFT LEVEL WINDS FOR THIS AFTERNOON...UNTIL THE PASSAGE OF
THE SURFACE TROUGH.

SEAS SHOULD RESPOND FURTHER TO THE INCREASED FETCH...ATTAINING
SMALL CRAFT LEVELS THIS AFTERNOON. THE SWELL SHOULD DROP BACK
BELOW SMALL CRAFT LIMITS LATER TONIGHT OR MONDAY MORNING.

LONG TERM...SEAS WILL GRADUALLY SUBSIDE MONDAY AS HIGH PRESSURE
BUILDS ACROSS AREA. A SERIES OF WEAK DISTURBANCES WILL IMPACT
REGION PERIODICALLY THROUGH THURSDAY...HOWEVER STRENGTH AND TIMING
OF THESE DISTURBANCES IS UNCERTAIN AT THIS TIME.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...NONE.
NH...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 8 AM EDT MONDAY FOR ANZ150.
