KEY MESSAGES
- A Cold Weather Advisory remains in effect for tonight through Wednesday morning for wind chill values as low as 23 degrees below zero.
- Temperatures rebound into the low 20s on Thursday and Friday, reaching normal to above normal values this weekend into early next week.
UPDATE
Issued 845 PM CST Tue Feb 18 2025
Thin high clouds are gradually spreading in from the west- southwest and delaying the temps from dropping as rapidly as the previous forecast expected. However, still looking at temps to fall enough with enough of a wind to still see wind chills dip into the upper teens and low 20s below zero range tonight after midnight, especially across central WI where the clouds are thinnest. Thus will let the Cold Weather Advisory ride as is. Otherwise the previous forecast remains on track with high pressure building across the region through the middle of the week with a gradually warming trend into the weekend.

SHORT TERM
Issued 200 PM CST Tue Feb 18 2025
Tonight through Wednesday night:
This evening lows will fall quickly again with another Cold Weather Advisory in effect tonight from midnight to 10am Wednesday. There is a bit of uncertainty with temperatures tonight given the pattern combined with the likelihood for high clouds to push in later tonight. The expectation is that temperatures may not fall much more once clouds push in but it could be well into the overnight hours before clouds fully push in. Current observations to the southwest have suggested a slower progression of broken to overcast high clouds. The lowest temps tonight will be focused further north with clouds pushing in from the southwest but most of the CWA should be expected to see near Cold Weather Advisory conditions again tonight with peak wind chills around -20 degrees.
Despite still being cold Wednesday we will start to see temperatures begin to moderate, especially as the upper closed low pivots through the central US Wednesday. The clouds will prevent us from getting quite as cold Wednesday night but we cannot rule out some light snow Wednesday late afternoon into the night. Nothing impactful is expected but some flurries to even light snow will remain possible (up to 20% chance) given the upper low pivoting through. The layer of dry air in the mid to upper levels is the primary drawback for potential but if that layer can moisten up enough it will increase our potential.
This is primarily the case for the northeast parts of the CWA based on the moisture profile in models.

LONG TERM
Issued 200 PM CST Tue Feb 18 2025
Thursday through Tuesday:
We will gradually start warming up into the weekend and especially into next week as the upper low pushes out and 1000-500mb thicknesses begin to turn back towards normal.
High temperatures for the weekend will creep back into the 30s with highs early next week getting into the 40s. It does look a bit more uncertain beyond the middle of next week for temps, however.
As for precip this looks to be a fairly quiet extended period.
While meridional flow aloft may make for some shortwave activity aloft the lack of moisture at various levels will likely play a large role in any precip potential. Perhaps the best chance in the extended period for precip will be Monday as a surface low tracks through the northern Great Lakes with a corresponding upper shortwave. The current track has the precip potential focused further north but that will likely be the next best chance for precip for the area in the extended period.

Thin high clouds are gradually spreading in from the west- southwest across southern WI late this evening. Expect to see the high clouds to continue to spread in overnight with VFR conditions. Winds will remain lighter out of the west-northwest generally less than 10 knots. Expect lighter winds and VFR conditions prevail with some mid-level cloud cover through Wednesday. Cannot rule out a brief period of snow flurries later Wednesday afternoon/evening which may bring some lower, MVFR ceilings and a brief drop in visibility, but the potential remains lower (<20% precip chances) given the drier air and high pressure set up just to the west.

Arctic high pressure centered over the northern Plains will strengthen slightly into this evening as it slips a bit further south. This will continue to bring brisk northwest winds into this evening. The ridge of high pressure will build southeastward, closer to the western Great Lakes tonight bringing lighter northwesterly winds back to the region. Lighter northwesterly winds linger through Thursday night as high pressure slowly slides southward through the eastern Great Plains. No nearshore small craft concerns expected for at least the next several years.
