DISCUSSION
KEY MESSAGE 1...
UPDATE...
IN COORDINATION WITH WAYNE NATIONAL FOREST, THE OHIO DIVISION
OF FORESTRY AND PBZ, ISSUED A FIRE DANGER STATEMENT THROUGH 00Z
THIS EVENING FOR ALL OF OUR SE OHIO COUNTIES. WAYNE NATIONAL
FOREST AND THE OHIO DIVISION OF FORESTRY PREFERRED AN FDS EVEN
THOUGH WE HIT RFW CRITERIA ON ALL COUNTS.
THE FREEZE WARNING FOR SOUTHERN PORTIONS OF THE FORECAST AREA,
WHERE THE GROWING SEASON IS IN EFFECT, HAS BEEN ALLOWED TO
EXPIRE WITH TEMPERATURES HAVING RISEN COMFORTABLY ABOVE
FREEZING.
157 AM UPDATE...
A PRONOUNCED RIDGE AND VALLEY TEMPERATURE SPLIT IS CURRENTLY
ONGOING EARLY THIS MORNING, CHARACTERIZED BY COLD AIR DRAINAGE
DROPPING VALLEY LOCATIONS INTO THE MID 20S WHILE RIDGES REMAIN
SLIGHTLY WARMER AMID LIGHT FLOW. A FREEZE WARNING REMAINS IN
EFFECT THROUGH MID-MORNING FOR THE ACTIVE GROWING SEASON AREAS
IN THE SOUTHERN COALFIELDS AND NORTHEAST KENTUCKY.
SURFACE HIGH PRESSURE DRIFTING EAST TODAY WILL PROVIDE PLENTY OF
SUNSHINE, ALLOWING TEMPERATURES TO REBOUND INTO THE 60S FOR THE
LOWLANDS AND 50S IN THE HIGHER TERRAIN. FORECAST SOUNDINGS
CONTINUE TO ADVERTISE A SUBSTANTIAL DRY LAYER FROM H800 TO H700.
DIURNAL MIXING WILL TAP INTO THIS DRY AIR, AND GIVEN THE KNOWN
MOIST BIAS OF THE NATIONAL BLEND OF MODELS DURING THE SPRING
SHOULDER SEASON, DEW POINTS HAVE BEEN MANUALLY ADJUSTED
DOWNWARD. THIS YIELDS MINIMUM RELATIVE HUMIDITY VALUES FALLING
INTO THE 15 TO 25 PERCENT RANGE ACROSS MUCH OF THE AREA THIS
AFTERNOON. SOUTHWESTERLY WINDS WILL ALSO INCREASE AS THE
PRESSURE GRADIENT TIGHTENS, YIELDING GUSTS OF 15 TO 25 MPH.
GIVEN THESE METEOROLOGICAL CONDITIONS OVERLAPPING WITH
CRITICALLY DRY 10 HOUR FINE DEAD FUELS, AN ELEVATED FIRE DANGER
EXISTS. IN COORDINATION WITH FORESTRY PARTNERS, A FIRE DANGER
STATEMENT IS BEING ISSUED FOR ALL WEST VIRGINIA, KENTUCKY, AND
VIRGINIA COUNTIES THROUGH EARLY THIS EVENING. OHIO MAY BE ADDED
INTO THE STATEMENT LATER THIS MORNING PENDING ADDITIONAL
COORDINATION.
KEY MESSAGE 2...
AS THE AFOREMENTIONED HIGH PRESSURE SYSTEM ANCHORS OFF THE
ATLANTIC COAST, A SUMMER-LIKE SOUTHWESTERLY RETURN FLOW WILL
ESTABLISH ITSELF ACROSS THE OHIO VALLEY FOR THE FIRST HALF OF
THE WORK WEEK. THIS WILL ADVECT AN UNSEASONABLY WARM AIR MASS
INTO THE REGION. HIGH TEMPERATURES ON MONDAY WILL PUSH INTO THE
LOWER 70S ACROSS THE LOWLANDS. BY TUESDAY AND WEDNESDAY, HIGH
TEMPERATURES ARE FORECAST TO SOAR INTO THE LOW TO MID 80S FOR
THE METRO VALLEY AND LOWLAND AREAS, WHICH IS WELL ABOVE LATE
MARCH NORMALS.
KEY MESSAGE 3...
WITH THE INCREASING WARMTH AND MOISTURE ADVECTION, THE PATTERN
BECOMES INCREASINGLY UNSETTLED. ISOLATED SHOWERS OR
THUNDERSTORMS ARE POSSIBLE AS EARLY AS MONDAY NIGHT ACROSS
SOUTHEAST OHIO AS WEAK DISTURBANCES RIPPLE THROUGH THE
SOUTHWESTERLY FLOW ALOFT.
A MORE PRONOUNCED SYSTEM AND AN ASSOCIATED COLD FRONT WILL
APPROACH THE REGION TUESDAY NIGHT INTO WEDNESDAY, BRINGING MORE
WIDESPREAD SHOWER AND THUNDERSTORM CHANCES. WHILE DEEP LAYER
SHEAR APPEARS MARGINAL, GENERALLY IN THE 30 TO 35 KT RANGE, THE
PRESENCE OF STEEP LOW LEVEL LAPSE RATES AND SUFFICIENT
INSTABILITY DURING PEAK AFTERNOON HEATING COULD SUPPORT A FEW
STRONGER STORMS.
FORECAST UNCERTAINTY INCREASES SIGNIFICANTLY BY THURSDAY AND
FRIDAY REGARDING THE SOUTHWARD PROGRESSION AND POTENTIAL
STALLING OF THE FRONTAL BOUNDARY. MODEL GUIDANCE DIVERGES ON
WHETHER THE FRONT PUSHES SOUTH OF THE AREA OR STALLS ACROSS THE
OHIO RIVER VALLEY. IF THE BOUNDARY STALLS, REPEATED ROUNDS OF
CONVECTION TRACKING OVER THE SAME NARROW VALLEYS OF THE
APPALACHIAN TERRAIN COULD POSE A LOCALIZED FLASH FLOODING
THREAT. AT THIS TIME CONFIDENCE IS LOW.
AVIATION /13Z SUNDAY THROUGH THURSDAY/
VFR CONDITIONS WILL PREVAIL ACROSS ALL TERMINALS THROUGH THIS TAF
PERIOD WITH JUST THIN CIRRUS DURING THE DAY TODAY THICKENING
OVERNIGHT TONIGHT. COULDN'T COMPLETELY RULE OUT A STRAY SHOWER
TOWARD MONDAY MORNING.
LIGHT AND VARIABLE WINDS WILL BECOME SOUTHWESTERLY BY LATE
MORNING, GENERALLY 8 TO 12 KTS, WITH OCCASIONAL GUSTS OF 15 TO
20KTS DURING PEAK AFTERNOON MIXING. WINDS WILL DECOUPLE AND
BECOME LIGHT AGAIN AFTER 00Z MONDAY.
