000 FXUS61 KCAR 260645 AFDCAR AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CARIBOU ME 245 AM EDT SAT JUL 26 2014 .SYNOPSIS... HIGH PRESSURE OVER THE MID ATLANTIC STATES WILL MOVE EAST TOWARD THE OPEN ATLANTIC TODAY. LOW PRESSURE WILL APPROACH FROM THE WEST TONIGHT THEN CROSS THE REGION SUNDAY INTO MONDAY. && .NEAR TERM /THROUGH TONIGHT/... SURFACE HIGH PRESSURE WILL REMAIN TO OUR SOUTH TODAY WHILE AN UPPER LEVEL LOW REMAINS CENTERED TO THE EAST OF HUDSON BAY CANADA. ALL IN ALL ONE MORE FAIR WEATHER DAY CAN BE EXPECTED TODAY WITH NEAR TO SLIGHTLY ABOVE NORMAL TEMPERATURES. THE ONLY FLY IN THE OINTMENT WILL BE THE POTENTIAL FOR AN ISOLATED SHOWER LATE THIS AFTERNOON INTO THIS EVENING AS A RESULT OF A WEAK UPPER DISTURBANCE CROSSING THE REGION COMBINED WITH DAYTIME HEATING. TONIGHT WILL SEE INCREASING CLOUDS AS THE NEXT MORE POTENT SHORT WAVE BEGINS TO APPROACH THE REGION FROM THE WEST. THERE IS THE CHANCE FOR A SHOWER LATE TONIGHT ALTHOUGH MOST OF THE NIGHT WILL BE DRY. LOW TEMPERATURES TONIGHT WILL MAINLY BE IN THE MID TO UPPER 50S ACROSS THE REGION. && .SHORT TERM /SUNDAY THROUGH MONDAY/... THE START OF THE WEEK LOOKS TO BE RAINY AS A LOW PRESSURE SYSTEM MARCHES EAST FROM THE GREAT LAKES AND INTO SOUTHERN QUEBEC, AN OCCLUDED FRONT IN TOW. THIS FRONT WILL SLOW DOWN AS IT APPROACHES THE PINE TREE STATE AS A SERIES OF LOWS DEVELOPS ALONG IT. THE EXACT TIMING AND PLACEMENT OF THE FRONT AND THE LOWS IS STILL UNCERTAIN, BUT SHOWERS WILL BE LIKELY BOTH SUNDAY AND MONDAY, WITH PERHAPS A BRIEF BREAK FROM THE RAIN SUNDAY NIGHT. THERE WILL BE SOME INSTABILITY AROUND, SO CAN`T RULE OUT A FEW THUNDERSTORMS BOTH DAYS. WITH PLENTY OF CLOUDS AROUND, BOTH DAYS WILL BE A BIT COOLER THAN NORMAL; MOST SPOTS WILL BE IN THE LOWER 70S FOR DAYTIME HIGHS. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... SHOWERS WILL CONTINUE TO BE POSSIBLE MONDAY NIGHT AND TUESDAY AS AN OCCLUDED FRONT WILL CROSS THE REGION AT SOME POINT DURING THAT TIMEFRAME; EXACTLY WHEN IS NOT WELL AGREED UPON BY THE LONGER RANGE FORECAST MODELS. THEREAFTER, THE REGION LOOKS TO BE UNDER A VERY NARROW RIDGE OF SURFACE HIGH PRESSURE. WHILE THIS WOULD ARGUE FOR DRY WEATHER, THERE IS STILL THE POTENTIAL FOR SHOWERS AS WE WILL REMAIN ON THE EASTERN SIDE OF AN UPPER LOW CENTERED NEAR HUDSON BAY. HAVE GONE WITH SLIGHT CHANCE POPS FOR WEDNESDAY THROUGH FRIDAY TO ACCOUNT FOR THE POTENTIAL FOR MAINLY AFTERNOON SHOWERS EACH DAY. AFTER A COOL DOWN EARLY IN THE WEEK, WE`LL SEE A GRADUAL WARMING TREND AS SOUTHWEST FLOW DEVELOPS ALOFT. && .AVIATION /07Z SATURDAY THROUGH WEDNESDAY/... NEAR TERM: MAINLY VFR THROUGH TONIGHT. SHORT TERM: MVFR CONDITIONS WITH LOCALIZED IFR CONDITIONS ARE EXPECTED SUNDAY THROUGH MONDAY IN WIDESPREAD SHOWERS AND SCATTERED THUNDERSTORMS. CONDITIONS COULD POSSIBLY IMPROVE BY TUESDAY, THOUGH AT LEAST OCCASIONAL MVFR COULD STILL STRIKE IN SCATTERED SHOWERS. VFR WILL RETURN WEDNESDAY AS HIGH PRESSURE TRIES TO TAKE HOLD. && .MARINE... NEAR TERM: WINDS/SEAS SHOULD REMAIN BELOW SMALL CRAFT ADVISORY LEVELS THROUGH TONIGHT. SHORT TERM: NO HEADLINES ARE ANTICIPATED THROUGH THE LAST HALF OF THE WEEKEND. HOWEVER, SOUTH FLOW IS PROGGED TO INCREASE MONDAY AHEAD OF AN APPROACHING FRONT. THIS WOULD ALLOW SEAS TO BUILD. WHILE WNAWAVE LOOKS A BIT OVERDONE (8-10 FT), WAVES AROUND 6 FEET SEEM REASONABLE. A SMALL CRAFT ADVISORY MAY BE NEEDED FOR MONDAY AND MONDAY NIGHT. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...NONE. MARINE...NONE. && $$ NEAR TERM...DUDA SHORT TERM...HASTINGS LONG TERM...HASTINGS AVIATION...DUDA/HASTINGS MARINE...DUDA/HASTINGS
