Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 337 PM CST Thu Dec 5 2019

SHORT TERM.

Tonight through Friday night . Forecast Confidence is High:

Low pressure will pass through the forecast area this evening into early tonight, dragging a cold front across southern Wisconsin. Dry weather will continue as this system moves through, with the better moisture/forcing remaining north of the low. Clouds will clear out later tonight behind the front as high pressure begins to move in from the west.

Mostly sunny skies are likely Friday with high pressure overhead. Temps will be colder tomorrow behind the cold front, though the sunshine should help temps up to around normal values for early December.

Clouds will increase Friday night as the high departs, but otherwise quiet weather and near normal temps will continue.

LONG TERM.

Saturday . Forecast Confidence High:

Quiet weather continues into the weekend as a mid-level ridge remains across the upper Great Lakes region and a surface high shifts eastward on Saturday. As surface highs kicks further east, southerly flow returns to the region and warmer temperatures are expected for Sunday with highs in the low to mid 40s.

Sunday through Thursday . Forecast Confidence Medium:

While southern Wisconsin enjoys a quiet start to the weekend, an upper-level trough begins to push across the Pacific Northwest Saturday night. As the trough progresses across the central CONUS, a surface low develops along the Colorado front range. As this system continues to traverse into the Upper Midwest, southern Wisconsin looks to be sandwiched between a right entrance of weak jet leaving the region and a left exit/diffluent of another, stronger 250mb jet Sunday night/Monday. This combined with low-level WAA, should provide enough synoptic lift to support increased precipitation chances beginning Sunday and continuing into Monday. At this time, it looks to start off as rain late Sunday and transition to snow for our northern areas and more of a snow/rain mix for our southern areas.

However, models are not in agreement on where the surface low will track. GFS/GEFS favors a more northward track over southern Wisconsin, while the ECMWF/CMC tracks the low further south across northern IL/northwest IN. Thus, depending on what solution materializes will dictate the precipitaion type across southern Wisconsin. Nonetheless, QPF totals for this event looks to be light at this time and is expected to diminish Monday night as a cold front pushes across the area.

Behind the cold front, expect frigid Arctic air to filter into Wisconsin as the upper-level trough axis pushes east by Tuesday and as surface high pressure builds across the northern Plain/Upper Midwest on Wednesday. Tuesday night looks to be our coldest night with overnight lows dipping into the single digits to around 0 degrees, while highs on Wednesday look to top off between 10-20 degrees.

AVIATION(21Z TAFS).

VFR conditions will persist through this afternoon. A wind shift to the northwest is expected this evening into early tonight as low pressure and an associated cold front move through. Winds will become gusty for a time overnight into Friday until high pressure begins to build in from the west during the day Friday. Low clouds are possible behind the front late evening into the early Friday morning hours as a colder airmass pushes in. Plenty of sunshine is then expected Friday as the high moves overhead.

MARINE.

Low pressure will slide across central Lake Michigan tonight. Gusty north to northwest winds will develop late tonight into Friday behind the low and associated cold front. Decided a Small Craft Advisory will be needed overnight tonight into Friday for the gusty winds and building waves.

Low pressure approaching from the Northern Plains will bring a round of gusty southerly winds Saturday into Sunday. Gale force gusts will be possible Saturday night into Sunday morning, with the strongest gusts likely across the northern half of the lake.

Gusty northerly winds will develop in the wake of the system later Monday into Tuesday, possibly approaching gale force. A much colder airmass spreading into the region next week will lead to freezing spray conditions.

MKX WATCHES/WARNINGS/ADVISORIES. WI . None. LM . Small Craft Advisory from midnight tonight to 3 PM CST Friday for LMZ645-646.

Small Craft Advisory from midnight tonight to noon CST Friday for LMZ643-644.
