Today through Tuesday Night:

Patchy ground fog can be expected in some locations this
morning, with light winds and a slightly more moist airmass over
the region. Highs today will be a few degrees warmer than
yesterday, with readings in the low 80s. Averages for this time
of year are in the upper 60s.

A dry cold front will pass through the area before daybreak on
Tuesday, with gusty northwest winds to around 30 MPH during the
day. Highs Tuesday will be in the mid 60s.

Winds should start to diminish late Tuesday afternoon as high

.LONG TERM...
Issued 249 AM CDT Mon Sep 30 2024

Wednesday through Sunday:

Temperatures will warm back into the 70s on Wednesday as the
high begins to push east of the area, and then into the mid 70s
on Thursday ahead of another cold front. This front will bring a
low chance (less than 30 percent) of showers to the region
Thursday night or early Friday. Highs Friday will be a touch
cooler, in the upper 60s to around 70.

High pressure behind this front looks to bring quiet and
pleasant conditions for at least the first half of the weekend.
Another front will start to take shape to our west during this
time, with some discrepancy as to whether that frontal passage
will take place late in the weekend or early next workweek.

.AVIATION...
Issued 249 AM CDT Mon Sep 30 2024

Patchy ground fog is expected this morning, especially at the
more rural airports. This should dissipate an hour or so after
sunrise, with light winds and VFR conditions expected through
the day today. VFR will prevail tonight into Tuesday morning,
with a strong but dry cold front passing through the region
before sunrise on Tuesday. This will bring gusty northwest winds
to the area for much of the day on Tuesday.

.MARINE...
Issued 249 AM CDT Mon Sep 30 2024

Low pressure over the Canadian Prairies will progress toward
Hudson Bay as it deepens today. The low is forecast to linger
over Hudson Bay on Tuesday, dragging a cold front across Lake
Michigan during the morning hours Tuesday.

Scattered showers are expected over the northern two-thirds of
Lake Michigan along and ahead of the advancing front. Gusty
northwest winds will quickly become established behind the front
on Tuesday. Gales are not expected at this time, though winds to
around 30 knots are likely over the southern third of the lake.
A Small Craft Advisory is in effect.

High pressure will then push through the central Plains and
lower Missouri Valley Tuesday, before moving into the Mid
Atlantic on Wednesday. Winds will turn more southerly Wednesday
in response, with increasing gusts over the northern half of the
lake. Another front is then expected Thursday into Friday, with
northerly winds expected behind the front.
