(Issued 919 PM CST Mon Nov 27 2023)

Bands of flurries redeveloped near a w-e sfc trough and the final trough passage aloft over srn WI. Large scale subsidence will kick in during the early morning hours, although clearing skies are already approaching from central WI. Either way, stratocumulus clouds should mostly dissipate by 12Z. A flat sfc ridge will then shift across srn WI on Tue with wly winds and warm advection beginning. The low level warm advection won't arrive until late in the day, so high temps only in the lower to middle 20s after a cold start in the upper single digits to teens.


(Issued 354 PM CST Mon Nov 27 2023)

Tonight through Tuesday night:

Partly cloudy skies via stratocumulus will last into the evening with some clearing late. Isolated to scattered flurries will still be possible as the stratocumulus clouds are within the dendritic growth zone.

Brisk winds will continue into the evening owing to a lingering tight pressure gradient and steep low level lapse rates, but winds should ease overnight. Lows will tank to the upper single digits to low teens over the area tonight making it downright chilly outside.

Tomorrow, another cold day is in store with highs in the low 20s.
Winds will be slightly lower as a high pressure skirts to our south and precipitation isn't expected. Some high clouds may return in the afternoon.


(Issued 241 PM CST Mon Nov 27 2023)

Wednesday through Monday:

The extended looks dry as we'll be largely missed by precipitation makers until the upcoming weekend. There is some slight potential our southeast sees some rain on Friday, but that would depend on wobbles in the track of the expected low pressure system that will pass over the Ohio River Valley late in the week. Right now, we're on the northern periphery of the system and we may stay completely dry. While conditions will likely remain dry until this upcoming weekend, temperatures will moderate into the mid 30s on Wednesday behind a warm front and then near 40 on Thursday, before a cold front comes through and knocks us down a few degrees for Friday.


(Issued 919 PM CST Mon Nov 27 2023)

Areas of MVFR Cigs and flurries this evening will end during the overnight including clearing skies. VFR conditions then expected for Tue-Tue evening but areas of MVFR Cigs could develop late Tue nt ahead of and along a sfc trough passage.


(Issued 219 PM CST Mon Nov 27 2023)

Breezy west to northwest winds will persist through tonight as a tight pressure gradient remains over the lake in the wake of a cold front. Then, winds should ease a bit on Tuesday as high pressure of 30.3 inches approaches the lake from the west. A warm front will then approach Tuesday night, flipping winds around to southwesterly and causing some gusty winds until dawn on Wednesday.
Winds will then gradually back off through Wednesday into Wednesday night.
