Tonight and Sunday Issued at 256 PM CST Sat Dec 2 2023

Key messages:

Light snow is likely late tonight and Sunday with the highest totals across eastern counties.

Skies were mostly cloudy this afternoon as temperatures warmed into the 30s to around 40. For tonight, low pressure will move into southern Wisconsin as an upper trough moves into the western Great Lakes. Light snow will break out ahead of the system. The latest model trends is to slow the arrival of the snow which will now be after midnight across central and east-central Wisconsin and probably won't make into northern Wisconsin until after 12z.
Low pressure will continue to move east into lower Michigan on Sunday. Light snow is expected to continue across much of the area during the morning, then taper off and end across much of the area during the afternoon.

Confidence is growing that most locations will see 1 to 3 inches of snow, except over the far north where totals will be less than an inch. The previous run on the ECMWF had nearly fourth tenths of an inch of liquid precipitation. The 12z run has backed off on those totals. The Dynamic Ensemble-based Scenario output indicated the highest chances of 3 inches of snow was over Calumet County which was only around 40%. One other area to watch is from eastern Marinette and eastern Oconto counties into Door County where the models try to wrap the precipitation across the counties longer on Sunday. Low level eastern winds and delta T's over the lake are around 13C and over the bay of 10C could add some enhancement to snowfall totals. However, low levels winds are only 10 to 15 knots and air temperatures will be a few degrees above freezing that may limit snowfall totals in this region.

The light snow will taper off and end across much of the area Sunday afternoon. High temperatures in the lower to middle 30s are expected.

Sunday Night Through Saturday Issued at 256 PM CST Sat Dec 2 2023

Key Messages:

- A mild weather weather pattern is expected next week, with a few chances for precipitation.

The upper wind pattern is forecast to be relatively low amplitude with high heights and split flow for most of next week. There is a Clipper system that will largely pass by to our soutwest Monday night and early Tuesday, but could bring a little snow to the southwest half of the forecast area.

There is some chance of a significant synoptic scale storm a week from tomorrow, as strong jet energy moves through the southern stream and weaker jet energy moves along the northern jet along the United States Canadian border. The models show varying degrees of phasing, and tracks for the storm, so it's too early to make any forecasts of precipitation types and amounts.

Temperatures will be five to ten degrees above normal on most days next week.

for 18Z TAF Issuance Issued at 1104 AM CST Sat Dec 2 2023

Pockets of MVFR CIGS will continue this afternoon with MVFR CIGS becoming more widespread earlier this evening, then falling into the IFR or lower category later this evening and overnight then continuing through much of Sunday. Snow will arrive across central Wisconsin, and then overspread much of the rest of the region between 06z-12z. Snow will then gradually taper off and end from west to east Sunday afternoon into Sunday evening along with improving CIGS. Around an inch or less is expected across northern Wisconsin with 1 to 3 elsewhere although there is potential for greater than 3 inches across portions of northeast Wisconsin.
