AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT ISSUED BY NATIONAL WEATHER SERVICE ALBANY NY 730 PM EDT THU SEP 6 2012 .SYNOPSIS... A WEAK COLD FRONT APPROACHING FROM THE EASTERN GREAT LAKES WILL BRING ISOLATED TO SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS INTO THIS EVENING. GENERALLY FAIR CONDITIONS ARE EXPECTED TONIGHT AND FRIDAY. A STRONGER UPPER LEVEL DISTURBANCE AND AN ASSOCIATED SLOW-MOVING COLD FRONT WILL BRING WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE NORTH COUNTRY ON SATURDAY. HIGH PRESSURE AND MUCH COLDER WEATHER IS EXPECTED SUNDAY THROUGH THE BEGINNING OF THE WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... SEVERE THUNDERSTORM WATCH 626 HAS BEEN CANCELLED. THERE ARE STILL SOME ISOLATED STORMS BUT ARE WEAKENING. THE STORMS NEAR RUTLAND ARE MOVING SOUTH OUT OF THE AREA. THE STORMS NEAR PBG AND HEADING TOWARD BTV SHOULD REMAIN ISOLATED AND SHOULD DISSIPATE IN NORTHERN VT IF THEY EVEN GET THERE. PUT ISOLATED STORMS INTO THIS EVENING JUST IN CASE THEY DO HOLD TOGETHER.

A STRONG UPPER SYSTEM AND ASSOCIATED COLD FRONT APPROACH BY SATURDAY MORNING AND AFFECTS OUR AREA SATURDAY AND SATURDAY NIGHT. THE TIMING OF THE ONSET OF SHOWERS AND THUNDERSTORMS A BIT IN QUESTION BUT AN INITIAL WAVE OF SHOWERS IS POSSIBLE ALONG THE ADVANCING NOSE OF A LOW LEVEL JET SEGMENT EARLY SATURDAY MORNING...THEN AS THE LOW LEVEL JET TRANSLATES NORTH AND EAST...SOME PARTIAL CLEARING AND DECREASING COVERAGE OF SHOWERS SHOULD TAKE PLACE THROUGH SATURDAY MORNING INTO EARLY SATURDAY AFTERNOON...ALLOWING FOR SOME WARMING. GUIDANCE SUGGESTS SOME DECENT DESTABILIZATION SATURDAY AFTERNOON...ALONG WITH SOME LOW LEVEL JET ENERGY...AND THE REGION SHOULD BE IN THE RIGHT ENTRANCE REGION OF AN UPPER JET SEGMENT.

SOUTHERLY WINDS COULD BE QUITE GUSTY IN THE VALLEYS AND THE EASTERN SLOPES OF THE GREEN MOUNTAINS. THE TIMING IF THE EXIT OF THE FRONT WILL DETERMINE HOW COLD TEMPERATURES CAN FALL SATURDAY NIGHT...AND GUIDANCE AT THIS TIME LOOKS LIKE IT TIMES THE EXIT EARLY ENOUGH THAT TEMPERATURES SHOULD FALL INTO THE LOWER TO MID 50S...WITH MID TO UPPER 40S IN THE ADIRONDACKS AND GREEN MOUNTAINS...AGAIN BASED ON THE TIMING OF THE EXIT OF THE FRONT BEING PRIOR TO DAYBREAK SUNDAY. && .LONG TERM /MONDAY THROUGH THURSDAY/...

HIGHS SHOULD BE IN THE 60S TO NEAR 70 IN THE VALLEYS AND UPPER 50S TO LOWER 60S HIGHER ELEVATIONS. THE COLL WEATHER...WIDESPREAD CLOUDINESS AND SCATTERED LAKE EFFECT SHOWERS SHOULD CONTINUE THROUGH MONDAY...ALTHOUGH THE SCATTERED SHOWER ACTIVITY COULD BE TOO ISOLATED BY MONDAY TO INCLUDE IN THE FORECAST AT THIS TIME...SHOWERS MAY NEED TO BE ADDED AT SOME POINT AS THE EVOLUTION BECOMES MORE APPARENT AS WE GET CLOSER TO MONDAY. HIGHS MONDAY IN THE 50S AND 60S....AND ON TUESDAY...WITH GRADUAL WARMING...IN THE 60S. NO CHANGES TO THE FORECAST FOR WEDNESDAY INT THURSDAY AS GENERALLY DRY CONDITIONS SHOULD PREVAIL WITH GRADUAL WARMING CONDITIONS AS FLAT UPPER RIDGING CONDITIONS BUILD INTO THE REGION. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/...
