UPPER LEVEL PATTERN CURRENTLY CONSISTS OF RIDGING OVER THE WESTERN
CONUS AND TROUGHING OVER THE EASTERN. AN H85 HIGH PRESSURE CENTER
WILL SLIDE ACROSS THE SOUTHERN APPALACHIAN REGION AS A WEAK VORT MAX
SWINGS THROUGH THE NORTHERN GREAT LAKES OVER THE NEXT 12 OR SO
HOURS. HIGH CLOUDS WILL RETURN FOR THE AM, THOUGH, LOW RH THROUGHOUT
LOWER LEVELS WILL HINDER PRECIP AT THE SURFACE. CONTINUED SEASONAL
TEMPERATURES WITH CLEARING SKIES ARE EXPECTED THIS AFTERNOON.
MILD TEMPERATURES AND DRY CONDITIONS CONTINUE WEDNESDAY AS THE
GENERAL SYNOPTIC PATTERN REMAINS FAIRLY PERSISTENT, WITH JUST MINOR
FLUCTUATIONS IN THE OVERALL AMPLITUDE OF THE TROUGH/RIDGE.
TEMPERATURES TREND WARMER AMONG H5 HEIGHT RISES DOWNSTREAM OF A PNW
SHORTWAVE THURSDAY. A SLIGHT UPTICK CAN ALSO BE NOTED IN WESTERLY
H85 FLOW THURSDAY. NBM PROMOTES A DRY FORECAST AT THIS TIME, BUT
CANNOT TOTALLY RULE OUT LOW CHANCES FOR LIGHT RAIN POTENTIALLY
MAKING WAY INTO FUTURE FORECASTS.
THE AFOREMENTIONED SHORTWAVE WILL CONTINUE EASTWARD FRIDAY,
EVENTUALLY PROMOTING A COLD FRONT MOVING THROUGH THE OHIO VALLEY AND
INTO THE TENNESSEE VALLEY REGION LATE FRIDAY. CURRENT TRENDS ARE FOR
THIS TO BE A WEAK FRONTAL PASSAGE BEING SO FAR DISPLACED FROM THE
PARENT LOW WELL OFF THE NORTHEASTERN SEABOARD. DRIER AND BREEZY
CONDITIONS FILTER IN BEHIND THE FRONT ON SATURDAY, WHICH COULD POSE
HEIGHTENED FIRE WEATHER CONCERNS FOR THOSE THAT DO NOT GET RAIN
FRIDAY NIGHT(SOUTHERN VALLEY). WARMING TREND EXPECTED LATE WEEKEND
INTO THE NEW WORK WEEK.
