.SHORT TERM...
Issued 337 AM CDT Wed Jun 5 2024

Today through Thursday:

A cold front and associated surface trough are working their
way through the area this morning. Showers and thunderstorms
occuring along and ahead of this front have largely dissipated
as of 330 AM, but some additional redevelopment is possible
later this morning across the east, before the front pushes into
Michigan. Slightly less humid air is expected in the area
today, though temperatures will remain on the warm side, with
highs in the mid to upper 70s.

Another shortwave and cold front will push into the area from
the west late this afternoon. Scattered showers and
thunderstorms are expected with this activity. With colder
temperatures aloft, a few sporadic instances of marginally
severe hail will be possible, along with gusty winds, as
stronger momentum aloft is mixed down to the surface. This
activity should clear the area shortly after midnight, with
cooler and drier air building in behind the front.

A cooler and windy day is expected for Thursday, with highs
generally in the mid to upper 60s. West to northwest winds will
gust to between 30 and 35 MPH. Scattered showers are expected
from a stratocu deck in the afternoon, but should dissipate by
mid evening.

.LONG TERM...
Issued 337 AM CDT Wed Jun 5 2024

Thursday night through Tuesday:

Breezy winds will continue for Friday and Saturday, as swift
northwest flow remains in place over the region. Drier air in
the mid levels will result in less cloud cover and lower rain
chances on Friday, with highs warming to around 70. Another
shortwave is expected to rotate through the area on Saturday,
with a corresponding increase in PoPs into the 20-30 percent
range. Highs Saturday are expected to be in the low to mid 70s.

A final frontal passage on Sunday will bring another 20-30
percent chance for diurnal showers, along with slightly cooler
highs around 70. We then begin to transition to a more zonal and
eventually southwest flow pattern next workweek, with a
corresponding warming trend into the mid week timeframe.

.AVIATION...
Issued 337 AM CDT Wed Jun 5 2024

A mix of VFR, MVFR, and IFR ceilings are moving through the
region this morning. Overall, flight conditions are expected to
deteriorate through the early to mid morning hours, as MVFR and
IFR become more widespread. Scattered showers and a few
thunderstorms will remain possible as well. Clouds should
scatter out rather quickly early this afternoon afternoon,
before returning, along with chances for showers and
thunderstorms, late this afternoon and this evening. West to
northwest winds will also become breezy at this time.

.MARINE...
Issued 337 AM CDT Wed Jun 5 2024

A cold front and associated trough of low pressure will sweep
across the lake this morning, turning winds to a westerly
direction. A secondary cold front will move through the lake
tonight, with gusty winds developing for Thursday. A Small Craft
Advisory will very likely be needed for Thursday, and perhaps
into Friday.

A large area of low pressure will gradually move through
southern Canada, just north of the Great Lakes through the end
of the week. Winds will remain westerly and breezy through this
period. Showers will be possible at times late week as
shortwaves move through the broad cyclonic flow across the
region.
