DISCUSSION
KEY MESSAGE 1...
OUR FLOODING THREAT ACROSS THE AREA LINGERS TODAY WITH MORE
ROUNDS OF MODERATE TO HEAVY RAIN AND SOME THUNDERSTORMS
EXPECTED THIS MORNING AND AFTERNOON WITH A STUBBORN SLOW MOVING
WARM FRONT. TODAY WILL BE A BIT OF A TRANSITION WITH THE
WIDESPREAD STRATIFORM COVERAGE OF RAIN BECOMING MORE OF A
SCATTERED CONVECTIVE MODE (ISOLATED RUMBLES OF THUNDER AND HEAVY
DOWNPOURS).
SEVERE WEATHER IS NOT ANTICIPATED IN OUR AREA TODAY AS IT WILL
RESIDE FARTHER WEST. THERE IS A SLIGHT RISK(LEVEL 2/4) FOR
EXCESSIVE RAINFALL ACROSS SOUTHEASTERN OHIO AND A MARGINAL
RISK(LEVEL 1/4)FOR NORTHERN WEST VIRGINIA THIS MORNING THOUGH.
A MARGINAL RISK OR SLIGHT FOR EXCESSIVE RAINFALL MAY BE
POSSIBLE ACROSS THESE AREAS AGAIN TODAY. WATER ISSUES ARE
EXPECTED TO CONTINUE OR MULTIPLE TODAY AS A RESULT SO THE FLOOD
WATCH CONTINUES UNTIL 1PM, UNLESS IT NEEDS TO BE EXTENDED INTO
THE EVENING.
OVERALL, SCATTERED INSTANCES OF MODERATE TO HEAVY RAINFALL WILL
CONTINUE TO SPAWN TO OUR SOUTH AND WEST THIS MORNING AND WILL
EVENTUALLY MOVE ACROSS THE AREA IN WAVES LATER IN THE MORNING
AND THROUGH THE AFTERNOON. A 70-90% PROBABILITY OF MEASURABLE
RAINFALL EXISTS INTO THE AFTERNOON FOR A BULK OF THE AREA.
CONVECTION CHANCES ARE LOWER AT 20-40% WITH THE HIGHER END BEING
ALONG AND NORTH OF THE I-64 CORRIDOR (SIMILAR TO YESTERDAY).
SHORT-RANGE, CONVECTIVE ALLOWING MODELS DIFFER ON TIMING AND
AMOUNTS. THE HRRR PLAYS THE ROLE OF "THE OPTIMIST" SHOWING THE
HEAVIEST RAIN EXITING BY 3PM TODAY WITH LESSER ADDITIONAL QPF
(0.10"-0.50") AND CONVECTIVE THREAT. HOWEVER, THE HRRR ALSO
SHOWS GREATER CLEARING THIS AFTERNOON, ESPECIALLY ACROSS OUR
SOUTHERN TIER, WHICH COULD IN TURN LEAD TO SOME INSTABILITY
LATER IN THE AFTERNOON.
THE HI-RES NAM, "THE PESSIMIST" SHOWS ANOTHER SCATTERED ROUND
LATER THIS AFTERNOON AND EVENING WITH A POSSIBLE AFTER DARK
EFFICIENT RAINFALL, EMBEDDED THUNDERSTORM EVENT. IT SHOWS SOME
ADDITIONAL QPF REACHING AROUND OR OVER AN INCH IN SOME SPOTS,
WHICH WOULD BE A WORST CASE SCENARIO IN REGARDS TO ONGOING
FLOODING.
THE HREF IS IN THE MIDDLE BEING THAT IT COMBINES THESE MODELS.
IT KEEPS THICK, CONVECTION LIMITING CLOUDS DRAPED OVER THE AREA
TODAY, BUT MODERATE TO HEAVY STRATIFORM RAIN WILL PERSIST THIS
MORNING INTO THE AFTERNOON. IT DOES SHOW MOST OF IT EXITING BY
5PM. QPF WITH THIS MODEL IS MODERATE AND REASONABLE BETWEEN
0.25" AND 0.75".
KEY MESSAGE 2...
TEMPERATURES THE NEXT FEW DAYS WILL FEEL REMINISCENT TO LATE
SPRING OR EARLY SUMMER AS OPPOSED TO LATE WINTER/EARLY SPRING.
TEMPERATURES TODAY ARE PROJECTED TO REACH THE UPPER 60S TO THE
MID 70S FOR MANY LOCATIONS IN THE LOWLANDS. ONE LIMITING FACTOR
WOULD BE THE CLOUD COVER WHICH MAY IMPEDE THIS DRASTIC WARMTH.
WOULD HAVE TO RELY ON AFTERNOON CLEARING THAT MAY OCCUR.
FRIDAY LOOKS TO BE THE WARMEST DAY AMID A THERMAL RIDGE ARRIVING
FROM THE SOUTH, WITH MODEL CONFIDENCE REACHING 90% TO 95% OF
REACHING OR EXCEEDING DAILY RECORD STATUS. FRIDAY'S TEMPERATURES
COULD TO REACH THE LOWER 80S FOR MANY OF THE USUAL WARM SPOTS IN
THE LOWLANDS. THE ONE LIMITING FACTOR IS ULTRA-SATURATED SOILS
FROM ALL OF THE RAIN.
SATURDAY WILL SHOWCASE WARMTH OF SIMILAR CALIBER TO FRIDAY, BUT
THE TIMING OF A STRONG COLD FRONT WILL BE THE DECIDING FACTOR ON
HOW WARM THE AREA GETS.
KEY MESSAGE 3...
AS MENTIONED ABOVE, A STRONG COLD FRONT WILL CROSS SOMETIME
SATURDAY AFTERNOON OR EVENING. A STOUT WARM SECTOR WILL LIE
ACROSS THE AREA, AS WILL TYPICAL SPRINGTIME WIND DYNAMICS(40-50
KNOTS OF SHEAR). THE RISK FOR STRONG TO SEVERE THUNDERSTORMS IS
CERTAINLY ON THE TABLE. POSSIBLE RISKS WOULD BE DAMAGING WINDS,
SMALL HAIL AND AN ISOLATED TORNADO THREAT.
THE GFS WANTS TO BRING THIS FRONT THROUGH VERY EARLY 1PM TO
3PM. THIS WOULD LIMIT THE STORM SEVERITY AND FLOODING RISK AS
THIS TIMING WOULD MOVE IT THROUGH FASTER, BUT THE DAMAGING WIND
WIND RISK WOULD BE OF CONCERN.
THE EURO GOES WITH A MUCH LATER TIMING 5PM-7PM. THIS WOULD ALLOW
FOR MORE INSTABILITY FOR STORMS TO TAP INTO, PRE-FRONTAL STORMS
WOULD BE POSSIBLE AND ROTATING STORMS/ISOLATED TORNADOES WOULD
BE POSSIBLE WITH HELICITY VALUES IN THE 100-300M/S RANGE.
THE CANADIAN IS THE SHOWS THE LATEST TIMING(5PM-10PM) AND
FAVORS A NOCTURNAL LINEAR OR QLCS SET-UP FEATURING PRIMARILY
DAMAGING WINDS. THE NAM12K SIDES CLOSER TO THE EURO WITH TIMING
SHOWING A LATE AFTERNOON/EARLY EVENING ARRIVAL. THE BETTER
RESOLUTION WITH THE NAM HIGHLIGHTS THE TORNADO CONCERN WITH THIS
TIMING SHOWING DISCRETE CELLS IN THE PRE-FRONTAL ENVIRONMENT
AHEAD OF THE MAIN LINE WITH THE FRONT.
AVIATION /06Z THURSDAY THROUGH MONDAY/
A SLUGGISH FRONTAL BOUNDARY REMAINS DRAPED ACROSS THE OHIO
VALLEY THIS MORNING, KEEPING DEEP MOISTURE AND WIDESPREAD
FLIGHT RESTRICTIONS IN PLACE. HIGH-RESOLUTION MODELS ARE
STRUGGLING WITH THE EXACT TIMING OF THIS RAIN SHIELD TODAY,
LEADING TO MODERATE CONFIDENCE FOR WHEN TERMINALS WILL RETURN
TO VFR LATER TODAY OR TONIGHT.
TERMINALS ACROSS THE LOWLANDS (KHTS, KCRW, KCKB, KPKB) ARE
CURRENTLY OSCILLATING BETWEEN MVFR AND IFR. THERE IS WIDESPREAD
LIGHT TO MODERATE RAIN AND MIST ARE KEEPING VISIBILITIES IN THE
2–5SM RANGE, WITH CEILINGS GENERALLY BETWEEN 800 AND 1,500 FEET
AGL. KEKN IS FIRMLY ENTRENCHED IN LIFR WITH DENSE FOG. KBKW IS
HOLDING VFR AT A HIGHER ELEVATION. IT IS POSSIBLE THAT SOME
LOWER CEILINGS AND SHOWERS REACH THEM BY ~12-14Z.
MOST TERMINALS SHOULD TREND TOWARDS VFR AS THE DEEPER MOISTURE
EXITS LATER TONIGHT. THE PRIMARY CONCERN WILL SHIFT TO RIVER
VALLEY FOG FOR ANY SITES THAT SEE RAINFALL TODAY.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z FRIDAY...
FORECAST CONFIDENCE: MEDIUM
ALTERNATE SCENARIOS: FLIGHT CONDITIONS WILL LIKELY BOUNCE
BETWEEN CATEGORIES FOR MANY SITES THIS MORNING. TIMING FOR
RAIN/THUNDERSTORMS AND IMPROVEMENT TO VFR MAY VARY FROM
FORECAST.
EXPERIMENTAL TABLE OF FLIGHT CATEGORY OBJECTIVELY SHOWS CONSISTENCY
OF WFO FORECAST TO AVAILABLE MODEL INFORMATION:
H = HIGH: TAF CONSISTENT WITH ALL MODELS OR ALL BUT ONE MODEL.
M = MEDIUM: TAF HAS VARYING LEVEL OF CONSISTENCY WITH MODELS.
L = LOW: TAF INCONSISTENT WITH ALL MODELS OR ALL BUT ONE MODEL.
