HIGH PRESSURE MOVES IN MONDAY...SETTING UP FOR A COLD NIGHT MONDAY NIGHT. COLD FRONT CROSSES MIDWEEK. && .NEAR TERM /THROUGH SUNDAY/... DRY SLOT PUSHING THE LAST OF THE SHOWERS FROM THIS MORNING TO THE NORTHEAST IN COUNTERCLOCKWISE SYNOPTIC SCALE FLOW...WITH A TOWERING CUMULUS FIELD FILLING IN. EXPECTING ECHOES TO FILL IN ON RADAR OVER THE NEXT COUPLE HOURS AS WELL...WITH WITH INSOLATION FURTHER DESTABILIZING MATTERS. PRECIPITABLE WATER VALUES HAVE COME DOWN A BIT FROM YESTERDAY...BUT STILL REMAIN NEAR 1 INCH OR SO. LOW LEVEL FLOW TURNS NORTHWESTERLY TONIGHT...WHICH SHOULD BRING ENOUGH LIFT FOR MORE SHOWERS AND ISOLATED STORMS CONCENTRATED OVER THE HIGHER TERRAIN. UPPER LEVEL LOW WILL WOBBLE SOUTHEAST AS WILL THE BROAD SURFACE LOW...AND EVENTUALLY BRING US BACK INTO A DRIER PATTERN BEGINNING SUNDAY EVENING. COULD SEE SOME CLEARING IN SOUTHEAST OHIO BY THIS TIME FRAME. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... 5H CUT-OFF LOW SLIDES EAST OF THE OUTER BANKS MONDAY...AS SURFACE HIGH OVER EASTERN CANADA SQUEEZED IN BETWEEN A PAIR OF SFC LOWS TO THE WEST AND EAST.

MID LEVEL GRADIENTS TIGHTEN IN RESPONSE TO A TROUGH AXIS SWINGING ACROSS THE NORTHEASTERN UNITED STATES. THE NORTHERLY FLOW INCREASES ACROSS NORTHERN TIER OF THE CWA LATE MONDAY INTO TUESDAY MORNING. A COOLER AIRMASS IS PROGGED TO SETTLE ACROSS EASTERN AND SOUTHEASTERN OHIO AND NORTHERN WEST VIRGINIA. JUST HOW MUCH OF THIS COLD AIR SEEPS SOUTH WILL PLAY A ROLE IN WHAT FROST-FREEZE PRODUCTS...IF ANY...WILL BE NEEDED FOR TUESDAY MORNING. NAM12 HAS BEEN CONSISTENT AND BRINGS COOLER AIRMASS A LITTLE FURTHER SOUTH INTO CENTRAL WV. HOWEVER...THE NAM12 IS ALSO THE OUTLIER FROM BOTH THE GFS AND ECMWF. FOR TEMPS...USED CONSENSUS GRIDS AND ADJUSTED THEM TOWARD THE INHERITED PACKAGE WHICH WAS ALREADY REFLECTING CURRENT MODELS TRENDS WELL. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... GENERALLY WENT WITH HPC THINKING WITH SOME TWEAKS. COLD FRONT PUSHES SOUTHEAST WEDNESDAY AND WEDNESDAY NIGHT WITH A CHANCE OF SHOWERS AND DAYTIME THUNDERSTORMS. IN ADDITION...MID-LEVEL SHORTWAVE WILL SWING BY WEDNESDAY EVENING. RESULTANT NORTHWEST FLOW AND SUFFICIENT LOW-LEVEL MOISTURE WILL RESULT IN CONTINUING SHOWER CHANCES IN THE MOUNTAINS INTO THURSDAY. HIGH PRESSURE TAKES CONTROL LATE THURSDAY INTO FRIDAY NIGHT...WITH DRY WEATHER ANTICIPATED. WARM FRONT WILL PUSH NORTHEAST LATE FRIDAY NIGHT INTO SATURDAY... BRINGING SHOWER CHANCES BACK INTO THE FORECAST. AN APPROACHING MID-LEVEL SHORTWAVE SHOULD RESULT IN INCREASING SHOWER CHANCES ON SATURDAY.

TOWERING CUMULUS MAKING A RETURN IN THE DRY SLOT ADVANCING NORTHEASTWARD THROUGH THE CWA. CB ABUNDANT IN THE TAF FOR AREA CONVECTION...BUT KEEP THE TAFS LARGELY VFR INTO EARLY TONIGHT. TERMINALS THAT EXPERIENCE SHRA OR TSRA MAY BRIEFLY EXPERIENCE MVFR...OR A MOMENT OR TWO OF IFR VISIBILITIES. NOT ENOUGH FOR PREVAILING CONDITIONS IN THE TAF ITSELF HOWEVER. SMALL HAIL POSSIBLE IN TSRA. NORTHWEST FLOW BRINGS MVFR DECK TONIGHT...BUT SHOULD ALSO LIMIT REDUCTIONS IN VISIBILITIES WITHOUT RADIATIONAL COOLING CONDITIONS. AGAIN...FEEL MVFR IS POSSIBLE HOWEVER TOWARDS DAWN. MORE CONVECTION EXPECTED AGAIN MONDAY...CONCENTRATED MORE IN THE MOUNTAINOUS REGIONS.
