Short term

Issued 1237 AM CDT Tue Oct 27 2026

Today through Thursday night:

Some localized patchy fog was able to develop late this evening despite the cloud cover. Temperatures were able to fall to the dewpoints or very close to (dewpoint depressions around 2 or less) under the diminishing winds. Winds are expected to remain light and temperatures should continue to fall as skies are clearing. Fog should stick to low lying areas and fields. If temperatures plummet under the clear skies the fog could potentially become more widespread and locally dense.

The upper level DIV and PVA that brought us the small chance for showers early this evening will continue to move northeast toward the Hudson Bay through today. As the trough pivots and moves northeast the upper level jet should increase at the sfc the low pressure system in Ontario should also strengthen which will tighten the pressure gradient across the Great Lakes Region. This will create some breezy conditions across the state. A few meso models are showing a bit of a weaker rain signal. The few models that are doing this are slower to bring in the mid level moisture and have a narrower moisture profile. This has effected the rain amounts with a cold front that is expected to pass through late Wednesday into Thursday. Despite this not expecting a ton of change here even if the moisture is a bit lacking this wasn't expected a huge rain producing event. The biggest change would be that rain is more along a scattered line. Either way there is still elevated CAPE in the area as well which will bring the chances for a few rumbles of thunder.

The front should clear Wisconsin during the morning hours with high pressure moving in behind it. Skies should quickly clear behind the front and some CAA will bring some cooler temps.

Long term

Issued 1237 AM CDT Tue Oct 27 2026

Wednesday through Monday:

High pressure will pull to the east of Wisconsin Friday which should swing winds back around to the east to southeast. This will bring back some WAA to the state. There is a bit of uncertainty on if the the mid level WAA will be enough to get some rain to develop. The forcing doesn't look all that great and moisture will still be lacking under the easterly winds. Conditions for rain starts to improve a bit heading to Friday night into Saturday as the trough advects northeast into the Central Plains and western Great Lakes. This track is still uncertain however. The GFS looks to be the furtherest north, EURO the furthest south with the CAN and NAM being some where in between. The NAM by far seems to be the slowest with this system at the edge of its forecast range. All these difference shift around the axis of rain and the strength of the system as a whole. At least we can bank on some consistency from the GFS as it remains the rainiest option for southern Wisconsin. Kept to the average among guidance which keeps POPS low around 15-30%.

Looking further ahead to into early next week, guidance is hinting at a larger and stronger low pressure system moving into the central CONUS. There is a bit of discrepancies as one would expect with the biggest caveats being how well the upper level flow merges together with a northern and southern track trough. The evolution of this system differs wildly from model to model, but this looks to kick off a more active period regardless.

Aviation

Issued 1237 AM CDT Tue Oct 27 2026

Clearing skies and falling temperatures across southern Wisconsin have brought about some patchy fog. With light winds expected to persist throughout the night, patchy fog may expand a bit leading to visibilities around 3-6 SM. If temperatures start to plummet fog could be locally dense, but confidence is low on this. Added some fog to the TAFs sites that are most likely to be effected. Low lying areas will be most susceptible tonight into early Wednesday. Fog should diminish shortly after sunrise.

Partly cloud skies during the day will increase Wednesday evening as a cold front approaches from the northwest. This afternoon ahead of the front south to southwest winds will become breezy with gusts of 20-25 kts possible (23-30 MPH). The best chances for stronger winds will be across east central Wisconsin. Late Wednesday into early Thursday rain and a few isolated thunderstorms will be possible. Winds will shift to northwesterly behind the cold front Thursday morning.

Marine

Issued 1237 AM CDT Tue Oct 27 2026

High pressure of 30.5 inches in western Quebec will continue east into the New England states. Meanwhile, a broad low pressure around 29.8 inches will move into the Northern Plains. Moderate east to southeast winds this evening will gradually become southerly by Wednesday morning. Breezy south winds will persist Wednesday, with gusts approaching gales across the far northern edge of the Lake Wednesday night ahead of an approaching cold front. Gusts will stop a couple knots short of gales over the northern end of Lake Michigan, though a few intermittent gusts to gale force can't be ruled out. For the nearshore zones, a Small Craft Advisory is in effect for areas north of north of Port Washington Wednesday evening through Thursday morning due to gusty southwest winds and building waves.

Winds then become southwesterly and come around to northwesterly following the front. Winds then quickly slow behind the front Thursday afternoon and evening as high pressure of 30.2 inches works in from the central plains.
