Updated aviation portion for 00Z TAF issuance

SHORT TERM. Tonight and Tuesday Issued at 237 PM CST Mon Jan 27 2020

Another winter day in Wisconsin . another day trapped under a strong inversion, keeping thick cloud cover across the area. Radar and surface observations showing a few flurries and some drizzle or freezing drizzle across portions of the area as well. Tonight looks to be a repeat of last night, with model soundings looking pretty similar with plenty of moisture trapped below 5000 feet and another weak shortwave trough dropping across the area. Although moisture remains at low levels, lack of deeper moisture and weak forcing will limit potential for light snow and more widespread areas of drizzle and freezing drizzle. But will keep small chances in the forecast once again. The Northwoods stands the best chance to see the precip (mainly snow showers) due to a little added moisture boost from Lake Superior. Little to no accumulation is expected. With the clouds not budging tonight, leaned heavily toward the warmer guidance for low temps, which keeps most spots in the 20s.

For Tuesday, any lingering flurries and freezing drizzle and drizzle will end early in the day for most spots as the weak shortwave exits to the east. However, snow showers could continue into the afternoon across the Northwoods as winds will remain out of the north, bringing some lake effect activity into the area. Otherwise, expect plenty of clouds to remain across the area as there is no sign of the moisture trapped under 5000 feet mixing out. Cold air advection behind the weak system will make for a slightly colder day across the area but highs will remain above normal.

LONG TERM. Tuesday Night Through Monday Issued at 237 PM CST Mon Jan 27 2020

Minor precipitation chances and mild temperatures are expected through the period, with the possibility of an arctic air mass arriving early next week.

High pressure will bring generally quiet conditions Tuesday night into Thursday. Light east to northeast flow could bring some disorganized light snow showers or flurries to the lakeshore counties Tuesday night into Wednesday, and a short-wave trof could bring some flurries late Wednesday into Wednesday night. But overall, we are just looking at a mostly cloudy period, with continued above normal temperatures.

There is potential for light snow from late in the work week into the beginning of the weekend, as an upper trof moves through the region. There are some timing issues, but overall this appears to be low impact for late winter. Quiet weather is anticipated Sunday into Monday.

A bigger warmup may arrive toward Monday, as south flow increases ahead of a cold front. The GFS model supports a decent shot of arctic air in the wake of this front, while the ECMWF is much less aggressive at this time. We have plenty of time to sort this out, and it is beyond the scope of this forecast.

AVIATION. for 00Z TAF Issuance Issued at 447 PM CST Mon Jan 27 2020

As an upper-level disturbance passes through the area tonight, MVFR to occasional IFR ceilings will be possible. The best chance of seeing high-end IFR conditions will be across central/north- central WI. Eastern areas will likely be kept up a bit by downsloping winds. A few flurries will also be possible overnight into early Tuesday morning, but little to no visibility restrictions are expected. Overall improvement will slowly begin late Tuesday afternoon, although MVFR clouds may be stubborn to leave.

GRB WATCHES/WARNINGS/ADVISORIES. NONE.
