KEY MESSAGES
- More widespread patchy fog is possible late tonight into Monday morning, especially near bodies of water.
- Temperatures will be 5 to 10 degrees above normal Monday through Wednesday, with highs ranging from the upper 60s to lower 70s.
- The risk of rain showers Wednesday afternoon into Wednesday evening has increased to a 40-60% chance as a cold blast sweeps across the region. Sprinkles will linger into Thursday with breezy and chilly conditions, followed by a 60-80% chance of highs struggling to reach above 50 degrees on Friday.
DISCUSSION
Issued at 1037 AM CST Sun Nov 8 2026
The growing season has come to an end this morning as high pressure will remain in control over the FA through Monday morning. Lows will not be as chilly, ranging from the mid 30s to near 40 degrees. Due to a modest increase in dewpoints today with southerly return flow, more widespread patchy fog will be possible late tonight into Monday morning, with the greatest risk near bodies of water. Otherwise, pleasant weather conditions with ample sunshine will start off the week as temperatures trend 5 to 10 degrees above normal through Wednesday. Highs will range from the upper 60s to lower 70s with lows only in the 40s.
As a 500 mb vort max ejects downstream from Iowa on Wednesday, model guidance is now in better agreement with a 1004 mb sfc low pressure system developing over central Illinois by Wednesday evening. The low will be associated with a strong cold front that is progged to sweep across the FA. Timing remains pretty consistent for rain showers, with a 40-60% chance developing Wednesday afternoon through Wednesday evening.
Rainfall amounts on ensemble guidance generally range between a tenth to a quarter of an inch on average.
Behind the front, a highly amplified trough settles over the Ohio Valley bringing the coldest airmass of the season through the end of the week. Residual 700 mb moisture on Thursday with prevailing northwest flow will support lingering sprinkles due to strong lift aloft. Wind gusts between 20-30 mph will also be possible with a rapid increase in cyclogenesis to the east. If moisture can linger into Thursday night, it would not be out of the question a wet snow flurry mixes in given extremely cold air aloft. While highs on Thursday are progged in the 50s, there is now a 60-80% chance of highs only in the 40s on Friday before temperatures begin to rebound over next weekend. Lows by the NBM next Saturday morning are currently progged in the upper 20s.
AVIATION /18Z TAFS THROUGH 18Z MONDAY/
Issued at 1037 AM CST Sun Nov 8 2026
Light westerly winds around 6-8 kts will turn calm tonight with mostly clear skies. While VFR conditions are forecast through most of the TAF period, included a TEMPO for IFR BCFG at KCGI as more widespread patchy fog development will be possible Monday morning. Vsby reductions at other terminals may eventually be needed as well if confidence increases.
