AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAY ME
553 PM EDT TUE JUN 23 2015
.SYNOPSIS...
A COLD FRONT WILL MOVE THROUGH THE REGION THIS EVENING...BRINGING
STRONG TO SEVERE THUNDERSTORMS THROUGH NEW HAMPSHIRE AND SOUTHERN
MAINE THIS EVENING. HIGH PRESSURE WILL BUILD INTO THE REGION
TONIGHT WITH GENERALLY DRY CONDITIONS EXPECTED THROUGH THURSDAY.
THE NEXT CHANCE FOR RAIN WILL ARRIVE BY THE END OF THE WEEK AS LOW
PRESSURE MOVES SOUTH OF THE REGION.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
MESOSCALE UPDATE: ONLY UPDATE NEEDED AT THIS TIME WAS TO ADD
ENHANCED WORDING OVER NORTHERN NEW HAMPSHIRE BASED ON RADAR
EVOLUTION OF CELLS IN THIS REGION WHICH CLEARLY INDICATE
SEVERE/TORNADO POTENTIAL FURTHER NORTH.
PREVIOUS DISCUSSION BELOW...
HIGH IMPACT WEATHER POTENTIAL: SEVERE THUNDERSTORM/TORNADO POTENTIAL
THROUGH THIS EVENING.
CURRENT PATTERN: AFTERNOON WATER VAPOR IMAGERY SHOWS AN IMPRESSIVE
SHORTWAVE PUSHING EAST TO THE NORTH OF NEW ENGLAND. THIS FEATURE IS
ASSOCIATED WITH A ROBUST /ESP FOR LATE JUNE/ SURFACE LOW OVER
QUEBEC...WITH TRAILING COLD FRONT NOW CUTTING THROUGH WESTERN NEW
YORK. WARM FRONT IS HUNG UP OVER MAINE AND NEW HAMPSHIRE...WITH
SIGNIFICANT CLEARING IN THE WARM SECTOR ALLOWING FOR RAPID RECOVERY
OF INSTABILITY /MLCAPES NOW REACHING BACK ABOVE 1000 J/KG...AND OVER
1500 J/KG OVER PARTS OF SOUTHERN NEW ENGLAND/. EFFECTIVE LAYER
SHEAR IS 40-50KTS IN THIS REGION WITH PLENTY OF SHEAR IN THE LOW
LAYERS /0-1KM SHEAR 20-25KTS/ SUGGESTS ALL THREATS /HAIL-WIND-
TORNADO/ ARE IN PLAY AS CONVECTION STRENGTHENS AND ARRIVES THIS
AFTERNOON AND CONTINUES INTO THE EVENING.
THROUGH THIS EVENING...SCATTERED/NUMEROUS STORMS WILL CROSS THE
REGION THROUGH 8 PM. SEVERE THREAT GREATEST OVER SOUTHERN NH
/THIS IS WHERE THE BEST INSTABILITY WILL BE REALIZED/...BUT ALSO
EXISTS THROUGHOUT THE REMAINDER OF THE STATE AND PARTS OF WESTERN
MAINE /BASICALLY FOLLOWING THE EASTWARD PROGRESS OF THE WARM FRONT/.
TORNADO POTENTIAL LOOKS GREATEST ALONG THE CONNECTICUT VALLEY /DUE
TO POTENTIAL FLOW CHANNELING/ AS WELL AS ALONG THE WARM FRONT NEAR
THE MAINE/NH BORDER.
GIVEN THE THREATS MENTIONED ABOVE...COORDINATED WITH SPC/BOX TO
ISSUE A TORNADO WATCH THROUGH 11PM THIS EVENING.
TONIGHT...INITIAL DRYING ALOFT BEHIND THE COLD FRONT SHOULD BE
STRONG ENOUGH TO BRING SIGNIFICANT CLEARING TO THE REGION OVERNIGHT.
LLEVEL DRYING IS A BIT SLOWER...SO WOULD NOT BE SURPRISED IF WE HAVE
TO DEAL WITH SOME FOG DEVELOPMENT OVERNIGHT...ESPECIALLY GIVEN THE
EVENING RAINFALL. LOWS WILL GENERALLY FALL BACK INTO THE 50S.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
HIGH IMPACT WEATHER POTENTIAL: MINIMAL.
PATTERN/IMPLICATIONS: BROAD NORTHWEST FLOW WILL OVERSPREAD THE
FORECAST AREA AS COLD FRONT AND ASSOCIATED SURFACE LOW/MID LEVEL
SHORTWAVE FROM TODAY PUSH EAST OF THE REGION. DRYING BEHIND THIS
DEPARTING SYSTEM WILL BE SLUGGISH TO OCCUR...SO FORECAST CONCERNS
WILL CENTER ON SHOWER CHANCES FOR WEDNESDAY/WEDNESDAY NIGHT.
WEDNESDAY...LOW LEVEL FLOW REMAINS CYCLONIC AROUND DEPARTING LOW
PRESSURE SYSTEM...WITH UPSTREAM SHORTWAVE PROVIDING SOME MODEST MID
LEVEL FORCING AS WELL AS AN UPTICK IN LOW AND MID LEVEL MOISTURE
/PWATS REACH BACK TOWARDS 0.75"/. COMBINED WITH DAYTIME
HEATING...EXPECT THAT THIS WILL RESULT IN A FEW AFTERNOON
SHOWERS...PRIMARILY OVER THE MOUNTAINS...WITH NORTHWESTERLY
DOWNSLOPE FLOW TO THE SOUTH AND EAST LIKELY KEEPING THIS AREA DRY.
COLD ADVECTION IS NOT ALL THAT ROBUST THROUGH THE DAY...SO HIGHS
SHOULD AGAIN REACH THE MID 70S THROUGH LOWER 80S...WHICH WILL BE
WARMER THAN TODAY ALONG THE MAINE COAST GIVEN THE OFFSHORE
TRAJECTORY. DEWPOINTS IN THE 50S WILL MAKE THINGS FEEL MUCH MORE
COMFORTABLE.
SIMILAR SITUATION FOR WEDNESDAY NIGHT WITH THE CORE OF THE UPSTREAM
SHORTWAVE MAKING IT/S CLOSEST APPROACH. WITH THE LOSS OF DAYTIME
HEATING...EXPECT THAT ANY SHOWER ACTIVITY WILL BECOME RATHER
ISOLATED AND WILL LIKELY CEASE ALTOGETHER AFTER MIDNIGHT. PLENTY OF
MID LEVEL CLOUDS OVERNIGHT WITH NORTHWESTERLY GRADIENT KEEPING MOST
IF NOT ALL LOCATIONS COUPLED. SO...DESPITE MODEST COLD ADVECTION...
EXPECT SEASONABLE LOWS GENERALLY IN THE 50S.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
THE MODELS ARE IN GENERAL AGREEMENT ON THE LONG WAVE PATTERN
THROUGH EARLY NEXT WEEK. WE BEGIN THE PERIOD WITH A BROAD LOW
AMPLITUDE TROUGH ACROSS THE REGION. THE PATTERN QUICKLY AMPLIFIES
WITH DEEP EASTERN TROUGH AND UPSTREAM RIDGE FOR WESTERN CONUS.
ANOMALOUS DEEP UPPER TROUGH WILL RESULT IN BELOW AVERAGE
TEMPERATURES FOR MUCH OF THE PERIOD. WE BEGIN THE PERIOD WITH A
WEAK RIDGE FOR THURSDAY. LOW PRESSURE SURFACE AND ALOFT VICINTY OF
THE GASPE PENISULA MAY PUSH SOME CLOUDS SOUTHWARD INTO OUR
NORTHERN AND EASTERN MAINE FORECAST AREA. THE NEXT IMPULSE
CROSSES THE AREA ON FRIDAY WITH A FEW CLOUDS AND A CHANCE OF
SHOWERS. FOR THE WEEKEND...ANOTHER SERIES OF IMPULSES PASS TO OUR
SOUTH. WHILE MOISTURE WITH THESE FEATURES STAY LARGELY TO OUR
SOUTH...A BROAD ONSHORE FLOW WILL KEEP US COOL WITH THE POTENTIAL
FOR SOME MARINE STRATUS AND FOG. THE COOL ONSHORE FLOW WILL
PERSIST INTO MONDAY...WITH NEXT IMPULSE POSSIBLY BRINGING A FEW
SHOWERS IN ADDITION TO THE MARINE STRATUS AND FOG IN LINGERING
ONSHORE FLOW.
&&
.AVIATION /22Z TUESDAY THROUGH SUNDAY/...
SHORT TERM...SOME NEAR TERM IMPROVEMENT FROM PWM WEST BEFORE
DEVELOPING SHOWERS AND THUNDERSTORMS BRING LOCAL MVFR/IFR
RESTRICTIONS WITH EMBEDDED SEVERE THUNDERSTORM WIND GUSTS
POSSIBLE ESP SOUTHERN NH/SOUTHWEST MAINE. EXPECT CLEARING THIS
EVENING AND OVERNIGHT /AGAIN SLOWEST AT AUG-RKD/ WITH SOME FOG
POTENTIAL HIE-LEB TOWARDS DAYBREAK. VFR CONDITIONS WEDNESDAY
THROUGH WEDNESDAY NIGHT UNDER NORTHWESTERLY WINDS.
LONG TERM...
FRI...SCT MVFR PSBL IN SHOWERS.
SAT - SUN...SCT MVFR PSBL NR THE COAST IN MARINE STRATUS AND FOG.
&&
.MARINE...
SHORT TERM...WINDS AND SEAS WILL INCREASE TODAY AHEAD OF OUR NEXT
WEATHER SYSTEM...PROMPTING SMALL CRAFT ADVISORIES. WINDS WILL
SUBSIDE TONIGHT...WITH SEAS REMAINING HIGH FOR A PERIOD. THEREFORE
SCAS WILL REMAIN IN EFFECT THROUGH LATE TONIGHT.
LONG TERM...
SUN...SMALL CRAFT WINDS/SEAS ARE PSBL OUTSIDE THE BAYS.
&&
.HYDROLOGY...
THE FOLLOWING RIVERS ARE NEAR FLOOD STAGE AND MAY BE IN DANGER OF
FLOODING IF THEY RECEIVE MORE PRECIPITATION IN THE NEXT 24
HOURS...THE CONNECTICUT RIVER AT DALTON...THE CONNECTICUT RIVER
AT WELLS RIVER...AND THE ANDROSCOGGIN RIVER AT GORHAM. WE WILL
KEEP A CLOSE EYE ON THESE RIVERS AS PRECIPITATION BEGINS LATE
TONIGHT INTO TOMORROW.
