.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 (12Z TAF Issuance)...
Issued at 635 AM EDT Thu May 28 2026

Impacts:

- Fog expected through 13Z, mainly near KHUF/KBMG

- Patchy dense fog possible near KBMG/KHUF through 13Z

Discussion:

Fog has developed near KBMG/KHUF/KIND and is expected to mix out by
mid morning. KLAF remains drier with fog unlikely. The lowest
visibilities are currently near KBMG/KHUF which could see
visibilities as low as 1/4 mile over the next hour or two. Expect
VFR cigs and vis through the period after the fog clears out.

NE winds will be around 5 kts or less through mid morning before
increasing slightly. During peak heating of the day, NE winds of 07-
11 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.

.IND WATCHES/WARNINGS/ADVISORIES...

051>057-060>065-067>072.
