KEY MESSAGES
- Showers/storms expected to reach the I-39 corridor this evening, then decreasing in coverage and intensity as they attempt to move east toward/east of the I-55 corridor.
- Typical July warmth and humidity through the week with periodic chances for showers and storms late Wednesday night through Friday
DISCUSSION
Issued at 253 PM CDT Tue Jul 2 2024
Through Wednesday:
After a persistent area of WAA-forced elevated showers north of I-80 this morning, the last few showers should be lifting north of the WI state line within the next hour. Otherwise, mostly sunny skies are expected through sunset as temps rise into the low to mid 80s for all areas except the northern tier of counties.
A mid-level wave just west of Kansas City early this afternoon will interact with a plume of higher theta-e air into central and eastern Iowa late this afternoon, fostering quickly growing convection into a generally linear MCS within the next few hours. The resulting convection is expected to track into a substantially less favorable environment around and east of the Mississippi River this evening into the early overnight hours as moisture decreases and mid-level lapse rates remain rather marginal for sustained organized convection. Expectations are for the convection to slow and weaken into a band of showers with some embedded thunder as far east as the Chicago metro.
Poor low-level thermodynamics will limit the amount of surface- based convection, but a narrow reservoir of 1000+ J/kg DCAPE nosing northeastward ahead of the convection early this evening could support a few strong wind gusts as far east as the I-39 corridor. Additionally, PWATs over 2" combined with weak backward propagating vectors and deep layer shear vectors only slightly oblique to the forcing may result in brief training and subsequent localized rainfall amounts of 1-2" across the western CWA
After the early overnight hours, residual convection and scattered showers will gradually drift southeastward as a cold front approaches from the northwest late tonight into Wednesday morning. The cold front should clear the southern CWA by late afternoon, with a vast majority of the CWA in line for a partly cloudy day with highs in the mid to upper 80s.

Wednesday Night through Tuesday:
A surface frontal boundary is expected to settle across downstate portions of IL and IN Wednesday night. This front is likely to remain the focal point for convective activity Wednesday night, especially south of our area. While our local weather looks rather quiet Wednesday night, conditions will remain on the warm and muggy side, with overnight lows only falling back into the mid to upper 60s.
The remnants of some of Wednesday night's convection will try to shift northeastward into parts of the area Thursday morning as a mid-level impulse tracks into the area. While a period of showers does look to be a good bet, especially for areas south of I-80 Thursday morning, poor lapse rates over our area will likely curtail the threat of thunderstorms through the morning.
Following the morning activity, a low (~30%) chance for some afternoon and evening thunderstorms exists. However, with the surface frontal boundary looking to remain south of the area until later Thursday evening and night, current thinking is that there will be a good amount of dry time for any outdoor 4th of July plans. Expect temperatures during the day to be in the low to mid 80s.
The next mid-level trough will shift eastward across the Upper Midwest late Thursday night into Friday morning. As it does, a surface wave of low pressure will lift northward into the western Great lakes while driving a surface cold frontal boundary eastward across our area into Friday morning. While the timing of this feature moving across our area will not be diurnally favorable, we will have increasing chances for a period of showers and thunderstorms late Thursday night into Friday morning.
Some showers, and possibly a few scattered storms may also linger into Friday afternoon across far northern sections of IL into WI as the central of the upper trough shifts overhead. Slightly cooler temperatures are expected, with highs generally in the upper 70s to low 80s.
The weather heading into the weekend overall does not look too bad at this time. It appears that we could have a good deal of dry time Saturday into Sunday before our chances for showers and thunderstorms begin to increase again with the approach of the next weather impulse late Sunday into Monday. Expect temperatures to be in the low 80s Saturday, and into the mid 80s for Sunday.

Forecast concerns include...
Chance of thunderstorms this evening and overnight.
Mvfr/ifr cigs overnight/around sunrise.
Gusty southerly winds this evening.
A line of thunderstorms currently extending from southwest WI through eastern IA into northern MO is expected to weaken as it moves into northern IL this evening, where instability is considerably weaker. Thunder will still be possible at RFD this evening, but confidence is low for the Chicago terminals until the overnight hours. During this time, some instability aloft develops as a cold front approaches and this may be enough for at least isolated thunderstorms. While confidence remains low for this time period, opted to convert current prob to tempo and trends will need to be monitored.
A period of mvfr cigs is expected overnight through daybreak Wednesday morning, clearing from northwest to southeast. Some of the guidance suggests ifr cigs will become prevailing across northwest IL, low mvfr across the Chicago terminals. Trends will again need to be monitored.
Southerly winds will gust into the lower/mid 20kt range through sunset this evening, with gusts to 20kt still possible later this evening as winds turn more south/southwest. Winds will turn more westerly by morning and remain west or west/northwest on Wednesday with speeds 10-12kts. Winds will diminish with sunset Wednesday evening. cms
