CONTINUED HIGH CONFIDENCE IN HEAT AND DAILY STORM CHANCES.
KEY MESSAGES
1) ANOMALOUSLY WARM TEMPERATURES THIS WEEK.
2) INCREASING DAILY STORM CHANCES THIS WEEK.
DISCUSSION
KEY MESSAGE 1...
CONTINUED RIDGING WILL PERSIST THROUGHOUT THE WEEK, KEEPING
HIGH TEMPERATURES ROUGHLY 15F TO 25F ABOVE AVERAGE, AND LOWS 20F
TO 30F ABOVE NORMAL. THIS EARLY-SEASON HEAT MAY POSE MINOR HEAT
RISK, PARTICULARLY GIVEN IT'S THE FIRST EXTENDED DURATION OF
HEAT THIS YEAR. BOUTS OF MODERATE HEAT RISK ARE ALSO POSSIBLE
FOR URBAN RIVER VALLEYS BY MID-WEEK. THIS GENERALLY ONLY IMPACTS
THOSE WHICH ARE SENSITIVE OR EXTREMELY SENSITIVE TO HEAT AND
WITHOUT COOLING/HYDRATION.
AREA RECORD HIGHS HAVE A 50/50 SHOT AT BEING BROKEN ON
WEDNESDAY. RECORD MAX LOWS HAVE A RISK OF BEING BROKEN
EVERYWHERE FOR MOST OF THE WEEK, WITH THE HIGHEST CHANCES IN
EASTERN OHIO AND NORTHERN WEST VIRGINIA ON TUESDAY AND
WEDNESDAY. THE BIGGEST FAILURE MODE FOR NOT REACHING RECORDS
WILL BE AFTERNOON STORM CHANCES (AND AFFILIATED CLOUD COVER).
SEE THE CLIMATE SECTION FOR MORE INFORMATION.
KEY MESSAGE 2...
THUNDERSTORM CHANCES INCREASE INTO THE WORK-WEEK WITH DAILY CHANCES
>30% PEAKING EACH AFTERNOON. THIS IS IN CONJUNCTION WITH RETURNING
MOISTURE AND >75% CHANCE OF NON-ZERO AFTERNOON BUOYANCY. THE REGION
WILL REMAIN PARKED UNDERNEATH A RIDGE AXIS WITH MULTIPLE SYSTEMS
LIKELY TO PASS TO THE NORTHWEST; THE HIGHEST CHANCES OF
CONVECTION AND SEVERE WEATHER, ALONG WITH THE HIGHEST CHANCE OF
INITIATION AND HIGHER SHEAR REMAIN NORTHWEST FOR NOW. LOCALLY,
THESE SYSTEMS ARE FAVORED TO SKIRT THE AREA, PROVIDING DAILY,
LOW (BUT NON- ZERO) CHANCES OF SEVERE WEATHER MONDAY AND BEYOND
(CSU MLP HAS ~5% WITHIN 25MI EACH DAY). CIPS INDICATE CHANCES
MAY INCREASE SOME WEDNESDAY, THURSDAY, AS ENSEMBLES FAVOR SOME
MINOR RIDGE FLATTENING, BRINGING STORM CHANCES FARTHER
SOUTHEAST.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
HIGH PRESSURE HAS SETTLED INTO THE REGION AND VFR CONDITIONS
ARE IN PLACE AT ALL THE TERMINALS. SOME 2 TO 4 KFT CU LAYERS ARE
STILL PRESENT BUT SHOULD BEGIN TO CLEAR OUT THROUGH THE LATE
AFTERNOON. EXPECT CLEAR SKIES OVERNIGHT. A PASSING HIGH CLOUD
LAYER IS POSSIBLE BY SUNDAY AFTERNOON.
WINDS WILL BE OUT OF THE NORTHWEST TO NORTH TODAY AND LIGHT AND
VARIABLE VALUES. WINDS WILL BEGIN TO GUST BY 15Z TO 16Z TOMORROW
AS WINDS SHIFT TO THE SOUTHWEST WITH SOME GUSTS TOMORROW UP TO
15 TO 18 KNOTS.
OUTLOOK...
THE POTENTIAL FOR PERIODIC RESTRICTIONS AND SHOWERS/THUNDERSTORMS
RETURN MONDAY THROUGH WEDNESDAY AS A COLD FRONT APPROACHES THE
AREA, AND THEN STALLS.
