NWS Caribou, ME wrote its last area forecast discussion before the first event at Jun 1, 11:02 AM EST, 2 hours 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CARIBOU ME 1202 PM EDT SAT JUN 1 2013 .SYNOPSIS... A COLD FRONT WILL PUSH SOUTH ACROSS NORTHERN MAINE TODAY THEN LIFT BACK TO THE NORTH AS A WARM FRONT LATE TONIGHT. A STRONG COLD FRONT WILL APPROACH FROM THE WEST LATE IN THE DAY SUNDAY AND VERY SLOWLY CROSS THE REGION SUNDAY NIGHT THROUGH MONDAY NIGHT. && .NEAR TERM /THROUGH TONIGHT/... UPDATED TO BEEF UP THE WORDING FOR HEAVY RAIN ASSOICATED WITH THE THUNDERSTORMS THIS AFTERNOON ACROSS CENTRAL AND INTERIOR DOWNEAST PORTIONS OF THE CWA. .PREVIOUS DISCUSSION... FOCUS TDY WILL REMAIN ON THE SHARP FRONTAL BNDRY WHICH IS FCST TO SLIP SWRD AND XTND WNW-ESE BTWN KBGR AND KHUL BY ERLY THIS AFTN. TO THE S AND W OF THIS BNDRY EXPECT VRY WARM AND HUMID CONDS ALONG W/ A CHC FOR SOME ISOLD TO SCT AFTN SHOWERS/TSTMS NR THE FRONTAL BNDRY. TO THE N AND E OF THIS BNDRY...EXPECT CLDS/ SHOWERS AND EMBEDDED THUNDER ALONG W/ COOLER TEMPS. PWAT VALS N AND E OF THIS BNDRY IN THE 1.5-2.0 INCH RANGE AND THIS COMBINED W/ STRONG ISENTROPIC LIFT WILL LIKELY GENERATE SOME LOCALLY HVY RAINFALL. IN ADDITION...SB-CAPES OF 1000-1500 J/KG SUGGEST SOME STRONG TO PSBLY SVR EMBEDDED TSTMS AS WELL. FINALLY...W/ THE VRY SATURATED GROUNDS ACROSS NRN AREAS FROM THE 3-5 INCHES OF RAIN OVR THE PAST WEEK...INCLUDING LOCALIZED AMOUNTS OF 1-3 INCHES FROM YESTERDAY/S DOWNPOURS...RESULTS IN AN ELEVATED FLOOD RISK AND THESE CONCERNS DISCUSSED IN MORE DETAIL IN THE HYDROLOGY SETION BLO... W/ THIS BNDRY ACROSS THE REGION TDY...WILL SEE A SHARP TEMP CONTRAST W/ TEMPS NR 90 PSBL ACROSS THE FAR SWRN AREAS. ACROSS THE FAR N AND NE...TEMPS EXPECTED ONLY INTO THE LOWER TO MID 70S. HOWEVER...COULD END UP A LITTLE COOLER DEPENDING ON HOW MUCH COOL AIR NE OF THE AREA CAN ADVECT INTO THESE AREAS AS WELL AS HOW MUCH IMPACTS THE CLOUDS AND SHOWERS END UP HAVING AS WELL... && .SHORT TERM /SUNDAY THROUGH MONDAY/... CONCERNS FOR THE SHORT TERM ARE FLOODING AND STRONG TO POSSIBLY SEVERE STORMS, ESPECIALLY SUNDAY INTO SUNDAY EVENING. THE FRONTAL BOUNDARY THAT HAS PLAGUED THE REGION OVER THE PAST FEW DAYS WILL LIFT NORTHWARD INTO QUEBEC SUNDAY AS LOW PRESSURE SLIDES OUT OF SOUTHERN ONTARIO. MEANWHILE, AN UPPER TROUGH AND SURFACE COLD FRONT WILL APPROACH FROM THE NORTHERN GREAT LAKES, PLACING NEW ENGLAND UNDER BROAD SOUTHWEST FLOW. THE REGION WILL ONCE AGAIN SEE A WARM, MUGGY DAY AS TEMPERATURES REACH THE 75-85 DEGREE RANGE AND DEWPOINTS PEAK IN THE LOWER TO MID 60S. EXPECT SHOWERS AND THUNDERSTORMS TO DEVELOP ONCE AGAIN, ESPECIALLY SUNDAY AFTERNOON AS THE UPPER TROUGH CLOSES IN FROM THE WEST. ANY ACTIVITY THAT POPS UP WILL HAVE PLENTY OF MOISTURE TO WORK WITH AS PWATS WILL BE VERY IMPRESSIVE, 1.5 TO 2.0 INCHES AREA WIDE. LOCALLY HEAVY DOWNPOURS ARE POSSIBLE, AND GIVEN HOW SATURATED THE GROUND IS FROM ANTECEDENT RAINFALL, FLOODING IS A POSSIBILITY. THE EXACT AMOUNT OF INSTABILITY IS STILL A BIT UNCERTAIN, AS MID-LEVEL LAPSE RATES WILL BE A BIT ON THE MARGINAL SIDE AT 6C/KM, BUT SURFACE-BASED CAPES OF 1000-1500 J/KG SHOULD BE SUFFICIENT FOR AT LEAST STRONG STORMS. A JET MAX ROTATING AROUND THE APPROACHING TROUGH WILL PROVIDE 30 TO 45 KT OF SHEAR, WHICH SHOULD BE ENOUGH TO SUPPORT ORGANIZED CONVECTION. INDEED, THE NEWEST DAY 2 SEVERE WEATHER OUTLOOK FROM SPC PLACES THE ENTIRE FORECAST AREA AWAY FROM THE OCEAN IN A SLIGHT RISK. GIVEN ALL THE ABOVE, HAVE KEPT ENHANCED WORDING IN THE FORECAST FOR SUNDAY AFTERNOON AND EVENING. THE AFOREMENTIONED COLD FRONT AND UPPER TROUGH WILL SLOWLY CROSS QUEBEC SUNDAY NIGHT. THOUGH PWATS WILL REMAIN HIGH SUNDAY NIGHT, THE LOSS OF DAYTIME HEATING WILL REDUCE INSTABILITY AND LIMIT ANY ADDITIONAL STRONG/SEVERE STORMS. HOWEVER, ANY SHOWERS OR THUNDERSTORMS WILL CONTINUE TO BE CAPABLE OF PRODUCING HEAVY DOWNPOURS. SUNDAY NIGHT WILL BE ANOTHER MUGGY ONE, THOUGH THE COLD FRONT MAY MAKE IT INTO THE FAR NORTHWEST, ALLOWING TEMPS AND DEWPOINTS TO DROP BACK INTO THE 50S. ELSEWHERE AWAY FROM THE COAST, EXPECT LOWS IN THE 60S. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... THE UPPER TROUGH'S SLOW EASTWARD PROGRESS ACROSS SOUTHERN QUEBEC/NEW BRUNSWICK WILL KEEP THE CHANCES FOR SHOWERS AROUND THROUGH TUESDAY, ESPECIALLY ACROSS THE NORTH. IT WILL ALSO KEEP TEMPERATURES COOLER, AS WELL, WITH HIGHS ONLY TO BE IN THE 60S TUESDAY AND WEDNESDAY. DRY CONDITIONS ARE EXPECTED FOR THE MIDDLE OF THE WEEK AS HIGH PRESSURE BUILDS OVER THE NORTHEAST. SHOWERS RETURN BY THE END OF THE WEEK AS A SHORTWAVE MOVING THROUGH SOUTHWEST FLOW ALOFT CROSS THE GREAT LAKES AND ENTERS SOUTHERN QUEBEC. && .AVIATION /16Z SATURDAY THROUGH WEDNESDAY/... NEAR TERM: IFR CONDS EXPECTED THRU THE ERLY AM HRS AT KFVE... OTHERWISE MVFR ACROSS THE N TDY W/ SHOWERS AND OCNL THUNDER AS A FRONTAL BNDRY SLIPS SWRD ACROSS THE NRN HALF OF THE AREA. MVFR TO IFR EXPECTED TNGT W/ OCNL SHOWERS AND AREAS OF FOG N W/ AREAS OF FOG S... SHORT TERM: VFR/MVFR CONDITIONS WILL PREVAIL SUNDAY THROUGH MONDAY, WITH IFR POSSIBLE IN ANY SHOWERS AND THUNDERSTORMS. THUNDERSTORMS WILL BE CAPABLE OF PRODUCING HEAVY RAIN, GUSTY WINDS, AND SMALL HAIL, ESPECIALLY AT THE NORTHERN TERMINALS. FOG IS POSSIBLE SUNDAY NIGHT AND MONDAY NIGHT, ESPECIALLY DOWNEAST, TAKING VISIBILITY AND CEILINGS DOWN TO IFR/LIFR. CONDITIONS WILL GRADUALLY IMPROVE TUESDAY AS HIGH PRESSURE BUILDS OVER THE REGION. EXPECT VFR AT ALL TERMINALS BY 00Z WEDNESDAY. && .MARINE... NEAR TERM: STABLE CONDS ACROSS THE WATERS THRU TNGT... WNDS/SEAS EXPECTED TO REMAIN BLO SCA LEVELS THRU TNGT BUT PERSISTENT SW FLOW WILL ALLOW SEAS TO SLOWLY BUILD TO AROUND 4 FT BY LATE TNGT... EXPECT SOME FOG SPCLY DURING THE OVRNGT HRS AS THE VRY WARM AND HUMID AIRMASS REMAINS OVR THE CHILLY GULF OF MAINE WATERS... SHORT TERM: HEADLINES MAY BE NEEDED LATE SUNDAY INTO MONDAY AS WINDS INCREASE AHEAD OF A COLD FRONT. SEAS WILL BUILD AS WELL, WITH A SWELL OF 8-10 FT. && .HYDROLOGY... HAVE DROPPED THE FLOOD ADV FOR FAR NWRN MAINE AS THE HVY RAINS HAVE WEAKENED AND SHIFTED N AND NE OF THESE AREAS... HAVE ISSUED A FLOOD WATCH FOR OUR NRN ZNS THRU 00Z MON. HVY RAINS OVR THE PAST WEEK HAVE LEFT SOILS SATURATED. A FRONTAL BNDRY WILL ACT AS A FOCUS FOR POTENTIALLY ADDITIONAL HVY RAINS TDY INTO TNGT ACROSS THE N AND E BEFORE IT LIFTS NE OF THE AREA LATE TNGT. THIS WILL BE QUICKLY REPLACED BY A STRONG COLD FRONT WHICH WILL APPROACH FROM THE NW LATE SUN... && .CAR WATCHES/WARNINGS/ADVISORIES... ME...FLOOD WATCH THROUGH SUNDAY EVENING FOR MEZ001>006.
