Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 155 PM CST Sun Jan 16 2022

SHORT TERM. (Issued 155 PM CST Sun Jan 16 2022)

Tonight through Tomorrow:

A band of light snow is moving across the area this afternoon. Thus far dry air is really limiting the amount of snow making it to the surface, with just a handful of snow reports so far. The rest of the afternoon will feature just very light snow showers, with perhaps a burst of slightly heavier snow where forcing can overcome the dry low levels. Only trace amounts of accumulation are expected.

Winds will become more northwesterly with time tonight, and will be gusty for a time late tonight and tomorrow morning as the surface pressure gradient tightens in response to strong low pressure moving up the east coast. Lows tonight will be in the teens.

Skies may clear for a brief time Monday morning before mid and high level clouds increase again as warm advection begins to develop to our west. Highs Monday will be in the upper 20s.

LONG TERM. (Issued 155 PM CST Sun Jan 16 2022)

Tomorrow Night through Sunday:

The next clipper starts to take shape over the Dakotas Monday night, with low level moisture increasing across the area with increasing warm advection. Forecast soundings are suggesting that the low levels may become rather saturated Monday night, potentially posing a risk for freezing drizzle late Monday night and early Tuesday. Not a great chance at this point, but something worth keeping an eye on.

Tuesday will be fairly mild, with highs in the low to mid 30s, before a cold front barrels through the area Tuesday night, dropping readings back into the teens. Could see a few flurries or snow showers across the northern half of the area Tuesday afternoon and night, but any meaningful snow will remain north of the forecast area.

Cold and dry really sums up the rest of the workweek, with little chance of additional precipitation through at least Friday. Thursday will be the coldest day, with highs likely only reaching the single digits. Will need to watch wind chills Wednesday night/Thursday morning and again Thursday night/Friday morning for values potentially approaching the -20 degree mark.

Heading into next weekend, guidance is suggesting another clipper or two swinging through the region, which would likely result in at least some low chances for precip, as well as a reinforcing shot of cold air.

AVIATION. (Issued 155 PM CST Sun Jan 16 2022)

Conditions are quite variable across the region this afternoon, with VFR mid and high level clouds across the eastern part of the region, and a mixture of IFR, MVFR, and VFR ceilings across the west. There are also some areas of light snow moving into the region right now, with associated visibility restrictions. The lower ceilings and snow chances will progress east across the region this afternoon. Snow will remain very light, and it's possible that some terminals may not see any snow at all.

Snow chances end early this evening, though MVFR ceilings will stick around until late tonight. By then, winds will switch to the northwest and start to become gusty, with gusts continuing into mid day on Monday. Ceilings will eventually lift and scatter out for a time late tonight, with VFR expected for a good part of the daytime hours on Monday.

Boxell

MARINE. (Issued 155 PM CST Sun Jan 16 2022)

Low pressure will move across Lake Superior into southern Canada this afternoon and night which will drag a cold front across Lake Michigan. South winds today will turn to the northwest tonight after the front passes by. Breezy northwest winds continue into Monday before briefly decreasing Monday night. A system moving across Lake Superior on Tuesday could bring a period of southerly gales Tuesday afternoon and then northwesterly gales on Wednesday.

A Small Craft Advisory is in effect from late tonight through mid day Tuesday for gusty winds. Additional advisories are likely for the nearshore waters Tuesday through Wednesday night.
