Saturday Night …
No Weather Hazards expected…
This Weather Outlook is for portions of North Central Illinois…Northeast Illinois and Northwest Indiana.
DISCUSSION…
Sunday’s primary highlight in the forecast is rain moving in tonight preceding dreary weather with steady rain expected from a storm system arriving from the southwest.
GOES 16 satellite shows water vapor channels spinning up across northern Texas into parts of southern Oklahoma. High clouds moved into Chicagoland late this afternoon, early evening.
The track of the upcoming storm system will be northeastward across the Ozarks and into the Mid-Mississippi Valley. A northward surge of moisture, originating from the western Gulf, and preceding the storm system, will drive a notable precipitation shield northward across central Illinois and into parts of northern Illinois and Indiana tonight. The deeper Gulf moisture (Precipitable waters ~1″) is forecast to move into southern counties of Chicagoland, south of I-80, late tonight after 2:00 a.m. Moderate rates of precipitation are expected south of I-80 during the overnight hours. Precipitation amounts forecast for Arlington Heights and the northwest suburbs have trended downward to about 0.33 inch of rain with peak precipitation from 8:00 a.m. to 2:00 p.m., and rain ending by 5:00 p.m. Mild weather follows Monday until Thursday, December 1, 2022 with Tuesday and Wednesday looking like the best days.

Area Forecast Discussion Two of Two
National Weather Service Chicago/Romeoville, IL
544 PM CST Sat Nov 26 2022
.SHORT TERM… Issued at 234 PM CST Sat Nov 26 2022
Through Sunday night…
The primary highlight in the short term centers around the dreary weather with rain expected across the area late tonight into Sunday in association with a storm system shifting across the region.
While conditions across the area early this afternoon are currently dry and mild, we do not have to look too far to our southwest to see the beginnings of our next approaching storm system, which is depicted nicely in the GOES 16 water vapor channels spinning up across northern TX into parts of southern OK. We are even now beginning to see signs of higher level cloud cover shifting northeastward into our area. Expect this cloud cover to become thicker with time through this evening as mid and higher level moisture continues to increase in advance of the southern Plains storm system.
With time tonight the track of this storm system will take it northeastward across the Ozarks and into the Mid-Mississippi Valley. A northward surge of moisture (originating from the western Gulf) preceding the storm system will drive a notable precipitation shield northward across central and into parts of northern IL and IN tonight. The deeper Gulf moisture (Precipitable waters ~1″) is forecast to shift into my southern counties (south of I-80) late tonight after 2 am, and this is expected to support some efficient moderate rates within this area through the overnight hours. In fact, rainfall amounts in my southern counties prior to daybreak Sunday morning may approach, or even exceed an inch. In sharp contrast, the rainfall looks to struggle to shift into far northern IL (north of I-80) tonight due to the impacts of a stubborn dry airmass currently overhead, which only looks to become reinforced by a northeasterly wind shift. For this reason, it may not be until towards daybreak Sunday morning that the rainfall makes it into far northern IL, especially towards the WI state line.
Not much has changed with the forecast thinking for Sunday, with it expected to be a dreary day with a cold rain and increasingly breezy northerly winds. There still remains the possibility that some of the rain could mix with or change to a short period of wet snow before ending over far northern and northwestern sections of the area late Sunday morning into the early afternoon as colder air filters into the deformation precipitation shield. However, this still appears to be a low chance, and if it does, little to no accumulation is anticipated due to warm ground temperatures. Otherwise, expect the precipitation to come to an end during the late afternoon and evening as the storm system quickly shifts towards New England.
