FORECAST UPDATE
ISSUED AT 359 AM EDT THU MAY 28 2026
A DENSE FOG ADVISORY HAS BEEN ISSUED FOR THE SOUTHERN TWO-THIRDS OF
THE FORECAST AREA. LATEST SURFACE OBSERVATIONS SHOW VISIBILITIES
HAVE GRADUALLY DROPPED OVER THE PAST SEVERAL HOURS. MULTIPLE SITES
ARE NOW REPORTING VISIBILITIES AROUND A QUARTER OF A MILE OR LESS.
MEANWHILE, TRAFFIC CAMERAS WITHIN THE ADVISORY ARE ALSO DEPICTING
MORE WIDESPREAD FOG DEVELOPMENT. FOG WILL LIKELY CONTINUE EXPANDING
IN COVERAGE THROUGH DAYBREAK.
IF TRAVELING THROUGH THESE AREAS THIS MORNING, BE PREPARED FOR FOG
THAT COULD SUDDENLY REDUCE VISIBILITIES TO 1/4 MILE OR LESS. THE
GREATEST REDUCTIONS IN VISIBILITIES WILL BE ACROSS MORE RURAL AREAS.
SLOW DOWN AND ALLOW EXTRA TIME TO REACH YOUR DESTINATION. EXPECT THE
FOG TO DISSIPATE BY MID MORNING.
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 (06Z TAF ISSUANCE)
ISSUED AT 139 AM EDT THU MAY 28 2026
IMPACTS:
- FOG EXPECTED THROUGH 13Z AT KBMG/KHUF WITH SOME POTENTIAL NEAR KIND
- PATCHY DENSE FOG POSSIBLE NEAR KBMG/KHUF
DISCUSSION:
HIGH PRESSURE HAS BUILT IN FROM THE NORTH PROVIDING MOSTLY CLEAR
SKIES AND LIGHT WINDS. CURRENTLY WATCHING THE PROGRESSION OF DRIER
AIR ADVECTING IN WITH THE HIGH AS THERE WILL BE A FOG THREAT DURING
THE OVERNIGHT HOURS BEFORE THE DRIER AIR ARRIVES. THINKING THE BEST
THREAT FOR ANY FOG WILL BE IN THE WABASH RIVER VALLEY AND THOSE
AREAS WHICH RECEIVED HEAVY RAINFALL EARLIER TODAY IN CENTRAL AND
SOUTH CENTRAL INDIANA. FOG HAS ALREADY DEVELOPED NEAR KBMG/KHUF AND
MAY DEVELOP NEAR KIND AFTER 08Z. KLAF REMAINS DRIER WITH FOG
UNLIKELY. LOOK FOR FOG TO DIMINISH BY MID MORNING.
N/NE WINDS WILL BE AROUND 5 KTS OR LESS THROUGH DAYBREAK. DURING
PEAK HEATING OF THE DAY TOMORROW, NE WINDS OF 08-12 KTS ARE
EXPECTED. A FEW GUSTS UP TO 18KT CANNOT BE RULED OUT, BUT THE
POTENTIAL IS FAR TOO LOW TO INCLUDE IN THE TAFS. EXPECT VFR CIGS AND
VIS DURING THE DAY TOMORROW.
