DISCUSSION
Issued at 304 PM CDT Sat Mar 14 2026
Through Monday:
Forecast concerns continue to focus on the significant storm system taking shape across the front range of the CO Rockies this evening.
Lee cyclogenesis is slatted to occur this evening over the central High Plains in response to a rapidly amplifying upper- level shortwave diving southeastward across the central United States. Ensemble model guidance remains in excellent agreement in tracking the surface cyclone eastward across the mid-Missouri Valley late tonight, then along or just south of the Illinois/Wisconsin state line Sunday afternoon. Thereafter, strengthening upper level diffluence ahead of the approaching negatively tilted mid- level trough will foster a rapid deepening of the low (to near 980 mb) as it lifts northward across lower Michigan Monday afternoon.
This storm system will produce several hazardous weather threats across our area Sunday into Monday. These include:
- Thunderstorms on Sunday, some possibly strong in the afternoon and early evening.
- Strong gusty south winds on Sunday, strongest southeast of I-55, where a wind advisory is in effect.
- Turning much colder and very windy from the northwest Sunday evening into Monday.
- Rain mixing with a brief period of sleet and freezing rain before transitioning to snow from west to east across the area Sunday evening and night.
Storm and Severe Threat Sunday:
At least a couple of waves of showers and thunderstorms are expected on Sunday. The first period favorable for mainly elevated storms will be during the morning hours of Sunday. Steep mid- level lapse rates could support the possibility for small hail with these storms. However, poor effective storm layer shear <25 kt suggests that organized severe storms are not likely with this initial morning round of storms.
Later in the day, particularly from mid to late afternoon into the early evening hours, the main storm system will be shifting across far northern IL. As it does, intensifying low-level winds (60+ kt at 850 mb) will foster a strongly sheared kinematic environment in advance of the eastward shifting cold front. In spite of this, the likely presence of low clouds in the warm sector through the day and only modest near surface moisture (dewpoints in the low 50s) is expected to stunt destabilization ahead of the approaching front. Nevertheless, strong convergence and forced ascent along the cold frontal boundary should still be able to support a forced line of shallow convection as it sweeps eastward across the area late in the day into the early evening. The primarily threat with this activity will be strong damaging wind gusts in excess of 60 mph.
Strong Non-Thunderstorm Winds Sunday:
Outside of the thunderstorms on Sunday, conditions are expected to become very windy through the day, particularly across southern sections of the area, where a Wind Advisory is in effect.
Increasing southerly winds, driven by rapid pressure falls in advance of the approaching surface low, are expected to result in gusts of 45, to perhaps briefly as high as 55 mph in the afternoon and early evening. The presence of lower cloud cover may limit the overall magnitude of the gusts to some extent. Because of this, in collaboration with neighboring offices, we have opted to convert the High Wind Watch to a Wind Advisory for Sunday into early Sunday evening. It is possible that this advisory need to be expanded a bit farther north with later forecast updates.
Winter Weather Threat Sunday night into Monday:
Rain will transition over the snow from west to east Sunday evening as a much colder airmass quickly spills in across the area along the backside of the deepening surface low moving into Lower Michigan. While a short hour or so period of mixed precipitation looks plausible, the main concern will the shift to accumulating snow in the presence of increasingly gusty northwesterly winds Sunday night into Monday morning. There continues to be some differences amongst guidance in terms as to how much additional moisture will fall as snow in the deformation band of the cyclone into Monday morning. However, given the expected track of the system, forecast thinking continues to favor the heaviest snow axis from northwestern IL into WI, with much lighter amounts with east-southeastward extent across our area. This results in general forecast snow amounts in the 2 to 5 inch range in my far northwest (near the Rockford area), dropping to only an inch or two across the Chicago area and points southeast.
Snowfall totals will not really be the main story with this wintry weather event. Really, the combination of falling snow with blowing snow on gusty northwest winds (45+ mph gusts) will be the primary concern locally with this event. While the snow character will start quite wet with a ratio near 10:1, which may initially limit accumulations on the wet/road ground, rapidly falling temperatures through the column will support a more fluffy (more blowable) snow late Sunday night into Monday. With this in mind, conditions should become more hazardous with time Sunday night, with the potential for periods of near blizzard conditions at times, particularly across the more open areas of northern/northwestern IL. These poor conditions are expected to continue into Monday morning before the snow gradually tapers off from south to north through the day on Monday.
No changes have been made to going Winter Storm Watch across the Rockford area, owing to the fact that potential warning level impacts will not onset here until sometime later Sunday evening.
We do envision that this gets transitioned to either a warning or an advisory as we get closer to the event. Winter Weather Advisory conditions could also expand east-southeast of the current watch area due to the combination of poor visibility in snow and blowing snow through Monday morning.
KJB
Monday Night through Saturday:
The low pressure system providing Monday's weather will continue to move east allowing for drier conditions over the region. 850 mb temperatures are expected to drop down around -20C overnight into Tuesday morning. Even as winds generally will be subsiding through the overnight, they are expected to remain breezy enough to drop wind chill values down to between -5 to -15F.
As a strong upper level ridge is expected to grow over the desert south west, weak northwest flow is forecast to remain over the western Great Lakes. There is still good agreement of another upper level shortwave embedded in the flow to pass over the area late Tuesday into Wednesday morning. This could provide another quick shot of some snowflakes to the area. But as the previously mentioned ridge expands through the week, temperatures are expected to rise into the 50s and possibly low 60s by the end of the work week with drier conditions.

Issued at 706 PM CDT Sat Mar 14 2026
A strong low pressure system tracking across northern Illinois Sunday afternoon will bring periods of strong winds and precip, including TS, Sunday and Sunday night.
Earlier SN associated with a mid-level warm front has exited north of the terminals, with any lingering IFR/MVFR ceilings also dissipating and moving north over the next hour or so. VFR conditions are then expected through the remainder of the evening and overnight. ESE winds of 10 to 15 knots will veer SE while beginning to gust to 25 knots overnight as a low-level jet settles over the area.
Winds will shift S/SSW while beginning to gust over 30 knots by late Sunday morning, with an axis of SHRA and embedded TS crossing the terminals mid morning into early afternoon in association with an approaching low-level warm front.
S/SSW winds will continue to increase during the afternoon, with frequent gusts around 35 knots and possibly to 40 knots.
Increasing low-level moisture will yield the development of MVFR ceilings as well as isolated to scattered light SHRA through much of the afternoon.
A strongly forced line of SHRA with possible TS will cross the terminals roughly in the 22-00Z window. The line will likely contain IFR visibility and bring a brief SW wind shift to 40 knots or higher. While lightning coverage may be low, the convective nature of the line warrants inclusion of TS mention in the TAF.
Behind the line and below a mid-level dry slot, low-end MVFR to possibly IFR ceilings and DZ are expected for much of the evening. SW winds will diminish slightly during this time before a main cold front shifts winds NW and increases gusts to over 30 knots. DZ may begin to transition to SN at the very end of the period, with the highest chances of any accumulating SN occurring beyond the TAF period late Sunday night.
