KEY MESSAGES

SHORT TERM
(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 223 PM EDT THU JUN 4 2026
HIGH PRESSURE OVER THE AREA WILL GRADUALLY GET PUSHED SOUTH AND EAST
THROUGH THE SHORT-TERM PERIOD. THE AIR MASS WILL REMAIN UNUSUALLY
DRY THROUGH EARLY FRIDAY AFTERNOON, WITH A MID-LEVEL SHORTWAVE
PASSAGE IN THE MID- TO LATE AFTERNOON FRIDAY REPRESENTING THE
LEADING EDGE OF INCREASED SOUTHWESTERLY TO WEST-SOUTHWESTERLY FLOW
AND RESULTING LOW-LEVEL MOISTURE ADVECTION. DAILY HIGH AND LOW
TEMPERATURES WILL CONTINUE TO RISE THROUGH THE PERIOD, WITH
OVERNIGHT LOWS WARMING AT A FASTER PACE THAN DAYTIME HIGHS.
LONG TERM
(SATURDAY THROUGH THURSDAY)
ISSUED AT 330 PM EDT THU JUN 4 2026
THE PATTERN WILL REMAIN AMPLIFIED OVER THE MAJORITY OF THE CONUS
THROUGH THE MIDDLE OF NEXT WEEK, WITH A TRANSITION TO BLOCKIER
FLOW AS WELL FOR THE LATTER PORTION OF THE EXTENDED PERIOD. A
RIDGE CENTER WILL BEGIN POSITIONED ACROSS THE SOUTHEASTERN U.S.
PROGRESSIVE SHORT WAVE ENERGY WILL BE RIDING EAST ACROSS THE GREAT
LAKES, WHILE A BROADER CLOSED LOW MEANDERS NORTHEAST FROM
SOUTHWEST TEXAS. MEANWHILE, A DEEP LOW PRESSURE SYSTEM WILL BE
MOVING ONSHORE ACROSS THE PACIFIC NORTHWEST WITH A SHARPENING
RIDGE AXIS ALIGNED FROM HUDSON BAY THROUGH THE NORTHERN
PLAINS/UPPER MIDWEST REGION. THIS RIDGE WILL GENERALLY EXPAND AND
EVENTUALLY TAKE UP MORE REAL ESTATE ACROSS THE MISSISSIPPI VALLEY
BY THE MIDDLE OF NEXT WEEK, WITH MORE OF AN OMEGA-TYPE BLOCK
PATTERN ESTABLISHED ACROSS THE CONUS BY THAT TIME. PLENTY OF
UNCERTAINTY CONTINUES REGARDING THE EXACT EVOLUTION OF THIS
PATTERN AND SMALLER-SCALE FEATURES THAT WILL DICTATE OUR WEATHER
DETAILS. THERE REMAINS HIGH CONFIDENCE WITH ABOVE NORMAL
TEMPERATURES CONTINUING ACROSS THE COMMONWEALTH, WITH GENERALLY
MORE UNSETTLED WEATHER, GIVEN THE GRADUALLY INCREASING LOW LEVEL
MOISTURE.
THE EXTENDED PERIOD OF DRY WEATHER WILL CONTINUE THROUGH SATURDAY,
WITH TEMPERATURES REBOUNDING INTO THE MID TO UPPER 80S ONCE AGAIN,
LIKELY A FEW DEGREES HIGHER THAN FRIDAY. A SURFACE COLD FRONT
WILL APPROACH THE AREA LATE SATURDAY NIGHT, WITH A SMALL UPTICK
IN RAIN CHANCES. GUIDANCE HAS GENERALLY TRENDED DOWN ON POPS
COMPARED TO YESTERDAY AT THIS TIME, WITH ONLY A FEW SHOWERS
LOOKING POSSIBLE. RAIN CHANCES STILL LOOK TO PEAK ON SUNDAY, AS
THE BOUNDARY DRAWS CLOSER, ALTHOUGH BEST CHANCES WILL GENERALLY BE
ALONG AND NORTHEAST OF KY-15. THE FRONTAL BOUNDARY WILL REMAIN IN
THE VICINITY OF THE AREA EARLY NEXT WEEK, KEEPING DIURNALLY DRIVEN
CHANCE POPS GOING. THIS REGIME WILL CONTINUE THROUGH THE MIDDLE OF
NEXT WEEK, ALTHOUGH POPS ARE LOWER CONFIDENCE, GIVEN THE
QUESTIONABLE FORCING AT THAT TIMEFRAME.
TEMPERATURES WILL WARM TO 5 TO 10 DEGREES ABOVE NORMAL BY THE
MIDDLE OF NEXT WEEK, WITH HIGHS MODIFYING FROM THE MID TO UPPER
80S, TO THE UPPER 80S AND NEAR 90 AT TIMES. LOWS WILL AVERAGE IN
THE 60S EACH NIGHT. DEW POINTS WILL ALSO GRADUALLY CREEP UP TO
MORE UNCOMFORTABLE LEVELS WITH TIME.
AVIATION
(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 116 PM EDT THU JUN 4 2026
VFR CONDITIONS WILL LIKELY PREVAIL THROUGH THE PERIOD WITH ONLY
SOME SPARSE FAIR WEATHER CUMULUS THIS AFTERNOON. VALLEY FOG IS
EXPECTED AGAIN TONIGHT, DIMINISHING GRADUALLY BETWEEN 12Z AND
14Z. KLOZ AND KSME MAY SEE A BRIEF REDUCTION IN VISIBILITY, BUT
CONFIDENCE IS TOO LOW TO INCLUDE ANY MENTION IN THE TAFS AT THIS
TIME. WINDS WILL BE LIGHT AND VARIABLE, OR FROM THE WEST OR
SOUTHWEST AT 5 KTS OR LESS, THROUGH THE PERIOD.
