SHORT TERM. Issued at 221 PM CST Sun Jan 16 2022

Through Monday night .

Upper-level satellite imagery depicts a sharp shortwave screaming southeast across the Upper Great Lakes on an approach to phase with the sprawling low pressure system across the southeastern United States. A narrow band of snow is evident along the leading edge of the shortwave, though ground observations reveal that hardly anything is surviving through a parched low-level airmass. While not sampled where snow is attempting to fall, recent AMDAR soundings from aircraft arriving and departing ORD, MDW, and MKE reveal the the mean 900 to 600 mb relative humidity across northeastern Illinois and southeastern Wisconsin ranges anywhere from 5 to 25%. Even with impressive upper-level lift / DCVA as well as steepening lapse rates in the heart of the DGZ, the prospects of snowflakes surviving the trip to the ground as the band sweeps across our area this evening seems to be lowering even as precipitation rates increase above the dry layer. We thus opted to cut back on the mention of snow in our official forecast, with a 20% chance of a flurry/light snow shower seeming appropriate (if not still a tad aggressive).

Snow or no snow, clouds will become overcast this evening and hold overnight lows close to 20 degrees. After midnight, a cold front will sweep across the area leading to blustery northwest winds. Depending on the eventual depth of the clouds after midnight (which partly hinges on how much saturation can be archived through virga this evening), a few snow grains cannot be ruled out through about daybreak. The best chances for snow overnight will be in far northeastern Porter County where the increasingly unstable waters of Lake Michigan and northwesterly fetch will afford the development of snow showers. With inversion heights expected to top off near 5000 feet (and entirely below the DGZ), a low-quality snow grain is preferred which will limit snow rates and accumulations. Snow should taper toward noon on Monday as inversion heights lower and moisture quality decreases, leaving behind perhaps as much as in inch or two in total snow accumulation (particularly northeast of a line from Portage to Malden). Elsewhere, tomorrow will start cloudy before mixing allows for at least pockets of mixing and clearing. Highs should top off in the upper 20s, but the blustery northwest wind will make it feel more like the teens.

LONG TERM. Issued at 221 PM CST Sun Jan 16 2022

Monday night through Saturday .

The long term period begins with slightly above normal temperatures for this time of year due to southerly winds advecting warm air into northeastern Illinois and northwest Indiana. Highs on Tuesday are forecasted to reach the mid to upper 30s with some locations possibly reaching 40 degrees. Lows on Tuesday night look to stay mild and in the low to mid 30s before a cold front pushes through the area. Temperatures will be dropping throughout the day on Wednesday behind the front with blustery northwesterly winds around 25 mph. The arctic airmass behind the front will create a cold conclusion to the work week with highs struggling to make it into the 20s and overnight lows in the low single digits and even sub-zero in places. Wind chills may drop to be well below zero in the negative teens through weeks end.

Precipitation chances with the aforementioned cold front look to be low due to a lack of moisture in the mid and upper-levels of the atmosphere. Current model guidance shows relative humidities struggling to reach 50% as the front moves through which should suppress any precipitation development. However, a band of moisture does look to develop and move down lake Michigan on the backside of the system Wednesday night into Thursday which would allow some lake-effect snow showers to develop across portions of northwest Indiana. Given the northwest flow in place, precipitation chances are expected to be higher towards northern Indiana and southwestern Michigan with lower chances further to the west. I have opted to keep slight chances of precipitation mentioned for the Indiana lakeshore and northeastern Porter county at this time to account for this potential.

The next chance for more widespread precipitation doesn't look to be until the weekend where models are showing another clipper system diving across the Great Lakes region. Forecast guidance is still uncertain on the timing of this system and the extent of the precipitation with it so I have opted to leave precipitation chances as they were from the NBM forecast.

AVIATION. For the 00Z TAFs .

525 PM . Forecast concerns include .

Chance of light snow this evening. Mvfr cigs overnight/Monday morning. Gusty northwest winds overnight thru Monday afternoon.

An area of light snow is moving across northwest IL and south/ central WI early this evening, dropping visibilities into the 2-3sm range for a short period of time. There is quite a bit of dry air in the low levels that this snow will need to saturate before reaching the ground across the Chicago terminals and as it saturates the low levels, it may begin to weaken/dissipate some, though confidence remains low. Much of the high res guidance then shows another area of light snow developing from the Chicago terminals south into central IL by mid evening. By that time, the low levels should be sufficiently moist that any snow that does develop should be able to reach the surface. For now, opted to carry tempo light snow with mvfr vis through 03z and monitor trends this evening. If snow does reach the Chicago terminals, possible vis briefly dips into the 2sm range. There will be a continued chance for flurries overnight.

A large area of mvfr cigs across MN/IA and western WI will move southeast across the area overnight and prevailing mvfr cigs are expected through much of Monday morning, slowly scattering and lifting Monday afternoon.

Westerly winds under 10kts will shift northwest later this evening with speeds/gusts increasing in the early morning hours. Gusts into the mid 20kt range are expected Monday morning. Gusts are expected to continue through sunset Monday evening, but should be slowly diminishing during the afternoon. cms
