HIGH PRESSURE BUILDS IN FOR THE MIDDLE AND LATTER PART OF THE WEEK.-- End Changed Discussion --&& .NEAR TERM /THROUGH TONIGHT/...-- Changed Discussion --A WEAK COLD FRONT WILL MOVE INTO THE MOUNTAINS TONIGHT. AHEAD OF THIS BOUNDARY THERE`S A SLIGHT CHANCE OF A SHOWER IN THE MOUNTAINS THIS EVENING...OTHERWISE SKIES SHOULD BE CLEARING ACROSS THE AREA OVERNIGHT WITH TEMPS FALLING INTO THE 40S TO LOWER 50S.-- End Changed Discussion --&& .SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...-- Changed Discussion --CLOUDS WILL BE ON THE INCREASE LATE SUNDAY MORNING AS A TROUGH APPROACHES FROM THE WEST. THIS WILL BRING THE THREAT OF SHOWERS TO WESTERN AREAS BY MID-AFTERNOON...WITH THE THREAT SPREADING EASTWARD DURING THE REMAINDER OF THE AFTERNOON AND EVENING. ALTHOUGH CAN`T RULE OUT AN ISOLATED THUNDERSTORM...THE ATMOSPHERE IS FORECAST TO BE FAIRLY STAPLE. TEMPS SHOULD REACH THE MID 60S IN THE MOUNTAINS TO 70S ELSEWHERE. THE TROUGH SWINGS THROUGH THE AREA SUNDAY NIGHT WITH THE THREAT OF SHOWERS DIMINISHING BY MORNING.-- End Changed Discussion --&& .LONG TERM /MONDAY THROUGH SATURDAY/...-- Changed Discussion --MONDAY MORNING STARTS WITH ZONAL FLOW ALOFT OVER NORTHERN NEW ENGLAND AND A WEAK SURFACE LOW JUST NORTH OF THE GREAT LAKES. AS AN UPPER LEVEL LOW OVER JAMES BAY BEGINS TO DROP SOUTHWARD ON MONDAY THE SURFACE LOW WILL BEGIN TO INTENSIFY. THE FLOW APPEARS TO BE FAIRLY FAST SO IT IS STILL QUESTIONABLE WHETHER OR NOT IT WILL BE STRONG ENOUGH TO BRING US SOME PRECIPITATION. THE BEST CHANCE LOOKS TO BE OVER THE MOUNTAINS. A WEAK COLD FRONT MOVES THROUGH ON TUESDAY...BUT WILL LIKELY BRING LITTLE IN THE WAY OF WEATHER. HIGH PRESSURE THEN BUILDS OVER THE REGION FOR THE REMAINDER OF THE FORECAST PERIOD.-- End Changed Discussion --&& .AVIATION /18Z SATURDAY THROUGH THURSDAY/...-- Changed Discussion --SHORT TERM...VFR CONDITIONS TONIGHT AND SUNDAY MORNING.
