Update

Issued 632 AM CDT Fri Oct 23 2026

Satellite imagery and observations supported cancelling the Dense Fog Advisory for Dodge County. Otherwise the advisory remains in effect until 10 AM CDT for ern WI. Some fog will likely linger toward noon or even into the afternoon near the lake. Light sely winds today will become sly winds and increase a bit tnt, while a narrow and high amplitude ridge builds aloft. Given that a drier airmass exists just to the south this morning, believe little to no fog will occur tnt. Middle to upper level clouds will also stream across the region tnt limiting the radiational potential for fog. Otherwise a very mild sswly flow will continue through the weekend but with more clouds as well.

Short Term

Issued 1151 PM CDT Thu Oct 22 2026

Tonight through Saturday:

Areas of fog will likely continue in the east into Friday morning and will be dense at times. The current Dense Fog Advisory runs until 10 am Friday and may need to be expanded a bit to the north and south based on latest webcams and observations. Latest models show that the bulk of the fog and low clouds should dissipate by mid-morning tomorrow, but wouldn't be surprised to see these conditions hang around in a few spots through late morning given the light winds. Southerly winds are expected to pick up a bit by the afternoon on the back side of high pressure, which should help to get rid of any lingering fog.

Temperatures will likely be slow to warm in the east tomorrow given the lingering clouds/fog, but there should be enough sunshine in the afternoon for highs back up in the upper 60s to near 70. Highs in the 71-74 range area likely in the west given more sunshine.

Southerly winds will persist Friday night into Saturday, as the high to the east isn't expected to budge. Though a fair amount of high clouds are likely Saturday, enough filtered sunshine is expected for highs around 70 again given the continued warm southerly low level flow.

Long Term

Issued 1151 PM CDT Thu Oct 22 2026

Sunday through Thursday:

Low pressure passing by well to the northeast on Sunday will drag a cold front through southern Wisconsin by the afternoon and/or evening hours. There should be enough time ahead of the front for southerly winds through at least the first half of the day, so another mild day is expected. Winds will shift to northerly behind the front later in the day, with cooler conditions then expected on Monday. Not expecting much moisture as this system moves through, so kept the dry forecast for Sunday and Monday.

Temps will remain cooler Tuesday, though likely still near or a couple degrees above normal for late October. A shortwave will lift through the region Tuesday into Tuesday night, though the main forcing and moisture is likely to remain north of the forecast area per latest models. Only have 10-20 percent chance for rain in the northwest as this system slides by to the north.
