KEY MESSAGES
- ABOVE NORMAL TEMPERATURES EXPECTED TODAY IN THE UPPER 70S TO MID
80S.
- DRY WEATHER EXPECTED TODAY THROUGH THE MIDDLE OF NEXT WEEK.
FORECAST UPDATE
ISSUED AT 923 AM EDT THU MAY 28 2026
FOG CONTINUES TO SLOWLY DISSIPATE ACROSS THE REGION THIS MORNING AS
BOUNDARY LAYER MIXING INTENSIFIES. WE'LL BE LEFT WITH FAIRLY BENIGN
WEATHER TODAY AS HIGH PRESSURE BUILDS IN FROM THE NORTH. HIGH CIRRUS
FROM UPSTREAM CONVECTION (OVER KANSAS AND OKLAHOMA) WILL SPREAD
EASTWARD TODAY AND SHOULD PREVENT US FROM HAVING A COMPLETELY CLEAR
DAY. NEVERTHELESS, THESE CLOUDS WILL BE THIN ENOUGH TO ALLOW FOR
FAIRLY EFFICIENT SOLAR INSOLATION AND HIGH TEMPS IN THE LOW TO MID
80S ARE EXPECTED.
DISCUSSION (TODAY THROUGH WEDNESDAY)
ISSUED AT 302 AM EDT THU MAY 28 2026
CURRENT SURFACE ANALYSIS SHOWS SURFACE HIGH PRESSURE CENTERED NEAR
LAKE SUPERIOR AND CENTRAL PORTIONS OF CANADA WHICH STRETCHES DOWN
INTO CENTRAL IN. SUBSIDENCE FROM THE HIGH HAS PROVIDED MOSTLY CLEAR
SKIES WHILE KEEPING WINDS VERY LIGHT OVERNIGHT. THIS COMBINED WITH
RECENT RAINFALL ON WEDNESDAY IS PROMOTING FOG DEVELOPMENT THIS
MORNING. THE GREATEST COVERAGE OF FOG WILL LIKELY BE NEAR OR SOUTH
OF THE I-70 CORRIDOR AS DRY AIR FILTERING INTO NORTHERN COUNTIES
SHOULD LIMIT SATURATION. PATCHY DENSE FOG IS ALSO POSSIBLE. IF YOU
ARE TRAVELING THROUGH THESE AREAS, BE PREPARED FOR SUDDEN REDUCTIONS
IN VISIBILITIES. EXPECT FOG TO DISSIPATE BY MID MORNING IN TYPICAL
DIURNAL FASHION.
GUIDANCE CONTINUES TO DEPICT AN OMEGA BLOCK PATTERN DEVELOPING ALOFT
WITH RIDGING CENTERED OVER THE CENTRAL CONUS AND CENTRAL PORTIONS OF
CANADA. MEANWHILE, SURFACE HIGH PRESSURE GENERALLY REMAINS IN
CONTROL ACROSS THE REGION. THIS WILL LIKELY PROMOTE DRY WEATHER
CONDITIONS THROUGH MOST OR ALL OF THE FORECAST PERIOD. EXPECT
ANOTHER WARM DAY TODAY IN THE LOW TO MID 80S WITH HIGHS THEN HOLDING
NEARLY STEADY IN THE MID TO UPPER 70S THROUGH EARLY NEXT WEEK.
A FEW MODELS HAVE HINTED AT THE RIDGE RETROGRADING SLIGHTLY,
ALLOWING FOR A SHORTWAVE TO MOVE IN ALOFT EARLY NEXT WEEK ALONG WITH
AN ASSOCIATED COLD FRONT. THESE SOLUTIONS ARE MOSTLY OUTLIERS, BUT
THIS WILL CONTINUE TO BE MONITORED AS THIS COULD IMPACT
TEMPERATURES. PRECIPITATION STILL APPEARS UNLIKELY EVEN IF A FRONT
DOES PUSH THROUGH DUE TO LIMITED MOISTURE RETURN.
AVIATION (18Z TAF ISSUANCE)
ISSUED AT 115 PM EDT THU MAY 28 2026
IMPACTS:
- NONE.
DISCUSSION:
VFR CONDITIONS EXPECTED.
SURFACE HIGH PRESSURE OVER THE GREAT LAKES WILL PROVIDE A NORTHERLY
WIND TODAY. WINDS GRADUALLY BECOME NORTHEASTERLY, AND THEN EASTERLY
ON FRIDAY, AS THE HIGH SLIDES EASTWARD.
HIGH CIRRUS FROM THUNDERSTORM ACTIVITY OVER THE GREAT PLAINS WILL BE
PRESENT AT TIMES THROUGH FRIDAY. PERIODIC VFR CEILINGS OVER 20,000
FEET ARE POSSIBLE.
IND WATCHES/WARNINGS/ADVISORIES
NONE.
