000 FXUS61 KBTV 030531 AFDBTV AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 131 AM EDT FRI JUL 3 2015 .SYNOPSIS... HIGH PRESSURE WILL PROVIDE GENERALLY FAIR WEATHER AND SEASONABLY MILD TO WARM TEMPERATURES THROUGH EARLY NEXT WEEK. OUTSIDE A STRAY LIGHT SHOWER SATURDAY NIGHT INTO SUNDAY MORNING NO PRECIPITATION IS EXPECTED ACROSS THE AREA THROUGH NEXT TUESDAY. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... AS OF 113 AM EDT FRIDAY...OVERALL FCST IN EXCELLENT SHAPE THIS MORNING...WITH ONLY CHANGE WAS TO DROP MIN TEMPS BY 1 TO 3 DEGREES ACROSS OUR REGION. THINKING LOWS WILL RANGE FROM THE MID/UPPER 30S SLK/NEK TO NEAR 50F CPV. MAINLY CLEAR SKIES WILL PREVAIL WITH SOME PATCHY FOG DEVELOPING IN THE DEEPER/PROTECTED RIVER VALLEYS. SOME MID LEVEL CLOUDS MAY IMPACT THE SLV TOWARD SUNRISE...BASED ON LATEST IR SAT SHOWING A NARROW RIBBON OF CLOUDS UPSTREAM. && .SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY NIGHT/... AS OF 308 PM EDT THURSDAY...HIGH PRESSURE THEN REMAINS IN GENERAL CONTROL OF REGIONAL CONDITIONS FOR FRIDAY INTO THE UPCOMING WEEKEND WITH MAINLY DRY AND SEASONABLY MILD TO WARM WEATHER EXPECTED. A WEAK SHORTWAVE TROUGH WILL SWING INTO THE REGION BY SATURDAY NIGHT, BUT WITH LIMITED MOISTURE AND DYNAMICAL FORCING REMAINING WELL OFF TO THE NORTH ONLY A TOKEN 10/20% POP WILL BE OFFERED FOR A STRAY LIGHT SHOWER/SPRINKLE, MAINLY NORTH. HIGH TEMPERATURES SHOULD RANGE FROM 75 TO 80 ON FRIDAY, THEN SLIGHTLY WARMER INTO THE UPPER 70S TO LOWER 80S BY SATURDAY THOUGH WITH ONLY MODEST HUMIDITY LEVELS. OVERNIGHT LOWS GENERALLY FROM 45 TO 55 FRIDAY NIGHT, THEN SLIGHTLY MILDER WITH A FEW MORE CLOUDS AND APPROACH OF THE UPPER TROUGH SATURDAY NIGHT (50S TO NEAR 60). SO JUST AN OUTSTANDING HOLIDAY WEEKEND LOOKS IN STORE WEATHERWISE. && .LONG TERM /SUNDAY THROUGH THURSDAY/... AS OF 323 PM EDT THURSDAY...THE EXTENDED BEGINS DRY THROUGH MOST OF EARLY NEXT WEEK. THERE WILL BE SOME POTENTIAL FOR SOME LIGHT OROGRAPHIC RAIN SHOWERS MAINLY IN THE WESTERN SLOPES OF THE GREENS ON SUNDAY BUT THE GUIDANCE SUGGESTS A DRY PATTERN WILL EMERGE EARLY NEXT WEEK WITH A BLOCKING UPPER LEVEL RIDGE CENTERED OVER THE CANADIAN MARITIMES. TEMPS THROUGH EARLY NEXT WEEK WILL SEE A WARMING TREND WITH A DECENT AMOUNT OF WARM AIR ADVECTION BRINGING IN HIGHER 850MB TEMPS FROM SUNDAY INTO MONDAY. EXPECT MAX TEMPS ON SUNDAY TO BE IN THE UPPER 70S TRENDING WARMER INTO THE MID TO UPPER 80S BY TUESDAY. GUIDANCE IS STILL HOLDING ON TO THE IDEA THAT A NORTHERN STREAM LOW PRESSURE SYSTEM WILL BRING A SURFACE BOUNDARY TOWARDS THE NORTH COUNTRY LATE TUESDAY INTO WEDNESDAY. THERE ISN`T MUCH CONSENSUS WITH THE 12Z SUITE OF GUIDANCE ON HOW THE SYSTEM WILL EVOLVE AS THE ECMWF BRINGS A PROGRESSIVE FRONT THROUGH AND THE GFS STALLS THE BOUNDARY WELL TO THE NORTH OVER CANADA. GIVEN THE DIVERGING SOLUTIONS I KEPT THE IDEA OF SHOWERS BUT HAVEN`T MENTIONED ANY THUNDER. THE DYNAMIC SUPPORT JUST ISN`T THERE TO MAKE ME FEEL COMFORTABLE WITH THAT JUST YET. I LEANED A LITTLE BIT MORE TOWARDS THE ECMWF SOLUTION BECAUSE OF THE 250MB STEERING FLOW. THEREFORE I DO HAVE A WEAK FRONT SLIDING THROUGH THE REGION LEADING TO SLIGHTLY COOLER TEMPERATURES ON WEDNESDAY AND THURSDAY BUT STILL IN THE UPPER 70S TO LOW 80S. && .AVIATION /06Z FRIDAY THROUGH TUESDAY/... THROUGH 06Z SATURDAY...VFR CONDITIONS WILL PREVAIL THROUGH PERIOD WITH THE ONE EXCEPTION BEING POTENTIAL IFR CONDITIONS FOR KSLK/KMPV AND MVFR CONDITIONS FOR FOR KBTV/KMSS AROUND 07Z-11Z DUE TO FOG/STRATUS.
