There is a mid-level trough over west central Texas (via SPC Mesoanalysis) that is expected to gradually move northeastward over the southern Plains today/tonight. Additionally, a stout 100+ knot upper jet is located over southeastern Ontario, placing northern Illinois in the right entrance region of its location and therefore in an area increased upper level divergence. For know, a near surface dry airmass has been winning the day keeping all activity on KLOT radar currently showing up in the western portions of the forecast area to mainly virga, to maybe a few sprinkles. As a plume of increased moisture and warm air advection moves into the area this evening and in the overnight, there is a better chance for increased coverage for light showers into Saturday morning. Given the unfavorable time of day, thunder is not expected. Although slightly steepening low/mid-level lapse rates keeps the chances non- zero, but below formal forecast mention.

As the upper level jet streak weakens and moves east tomorrow morning, the mid/upper level trough is expected to move over the western Great Lakes Saturday afternoon and evening. With weaker forcing and a lingering dry boundary layer air mass, confidence is lower for precipitation tomorrow evening. Slight chance PoPs were maintained for tomorrow night for the isolated chance for a light shower, if not just sprinkles/drizzle during any trick-or-treating. Certainly not any kind of washout, some areas will probably remain completely dry. But enough of a nuisance to keep precip mention in the forecast through Sunday morning.

A pseudo-stationary upper level cutoff low west of Seattle, WA is projected to finally move eastward over the intermountain west on Sunday as another short wave currently near Baja California moves northward, merging with the low, further amplifying the trough early next week. While specific details still need to be ironed out, models are showing fairly good agreement that this trough will induce surface cyclogenesis east of the Rockies and that will move over the Great Lakes in the middle of next week bringing better chances for widespread rain. Behind this system, a cooler airmass will drop temperatures down to make it feel a little more autumn-like.

Main Item of Note:

- Periodic -SHRA/sprinkles

There are no significant flying concerns through the period at the TAF sites, with primarily VFR conditions and east to southeast winds. Chances for any meaningful rain have continued to decrease, particularly at the Chicago metro sites. Maintained PROB30 mention for VFR light rain/sprinkles this morning through early afternoon. Additional isolated/widely scattered sprinkles can't be ruled out at any point this afternoon-early evening, though with no impacts expected, withheld additional mention from the TAFs.

At/near RFD, there's a bit better chance for higher shower coverage towards and after sunrise today. While confidence is on the lower side in any briefly higher rainfall rates, maintained MVFR VSBY in RFD's PROB30 for now.
