KEY MESSAGES

- Above normal temperatures today before a cool down this weekend

- Snow and rain/snow mix possible Friday/Saturday

- Next chance of light precipitation will be Tuesday/Wednesday

DISCUSSION
Issued at 256 AM CST Thu Dec 7 2023

Warm, above normal temperatures are possible across the region today. The question is how warm will it get? There are several things that add up to what could be a warm day. There is strong waa at 850mb noted on model soundings with a strong inversion/warm nose, upper high pressure ridge (sinking air) and cloud cover may lift northeastward by early afternoon. However, will the warm air aloft mix down with help of the clearing skies? Model soundings keep the inversion in place along with easterly/southeasterly winds which isn't a good direction for waa. Deterministic models tend to keep the temperatures in the upper 30s to low 40s with the HRRR being the somewhat outlier with temperatures to near 50 in portions of NW WI. Therefore, do not think the area will see record breaking warmth, but kept somewhat warm temperatures in the forecast because didn't have the confidence to drop temperatures.

The next opportunity for precipitation will come Friday afternoon mainly for the northwestern portions of the CWA as a trough enters the northern plains from MT. This trough will deepen by late Friday/early Saturday morning and with cold air in place from a cold front that is expected to swing through early Friday morning, the precipitation will be all snow. At least initially. As temperatures warm slightly over NW WI, the snow could transition over to a rain/snow mix.

As the trough swings through, winds will turn northwesterly leading to LES along the South Shore. Delta T Saturday ranges from 14-18C along with good omega in the DGZ. It is possible that northern Iron County will need a Winter Weather Advisory.
Outside the snow belt, not expecting much snow accumulation.
Mostly likely will be less than an inch.

The trough will exit late Sunday putting the region in northwest flow and leaving behind closer to normal temperatures. Next chance of light precipitation appears to be Tuesday into Wednesday.
