KEY MESSAGES

- Dry conditions continue through Friday along with above normal temperatures in the 80s. A few locations may approach 90 degrees on Friday, threatening daily record highs.

- Elevated Fire Weather Conditions are possible this afternoon, mainly across northern and eastern portions of the region, due to low RH's.

- Confidence is high that the remnants from Hurricane Isaias will impact our region this weekend. Widespread soaking rains appear to be the greatest impact, but gusty gradient winds are also possible. Peak timing for rain is Saturday into Saturday night, possibly lingering into Sunday morning.

DISCUSSION

Issued at 1258 AM CDT Thu Oct 8 2026

A weak front pushing south through the region will usher in drier northeasterly flow today. Drier air aloft will mix down with dew points falling into the 30s across northern and eastern areas of the cwa this afternoon. RAP/HRRR are typically good at handling these situations and both indicate RH's falling into the 15-20% range for areas along and north of Route 13 in southern IL, southwest IN, and the Pennyrile of west KY. Thankfully winds will be light, generally 5 mph at most. Despite the light winds, the RH's are low enough to lead to elevated fire weather conditions, so have issued an SPS for this.

Winds become southeasterly on Friday, which will lead to a very warm day ahead of the tropical system set to impact our region this weekend. Latest guidance is hinting at some 90 degree readings being possible, which may threaten daily record highs. Dew points creep upwards across the western 2/3rds of the region, but may remain quite low across the KY Pennyrile and southwest IN. This may lead to another day of RH's falling below 20% in these areas, as depicted by the HRRR/RAP. Winds will also be a bit stronger on Friday, generally between 5 and 10 mph. So another day of elevated fire weather is possible, mainly across our east.

Hurricane Isaias has formed in the southern Gulf and will move northeastward over the next 48 hours with a forecast landfall somewhere near Mobile/Pensacola Friday evening/night. The track has shifted east compared to 24 hours ago and also slightly faster. As the remnants get ingested into a shortwave trough sweeping through the lower Mississippi/Tennessee Valleys, moisture and large scale lift will quickly move north into our area on Saturday. A large shield of moderate to heavy rain will likely reach our southern border by late morning/midday and pivot north/northwestward through the afternoon. The heaviest rains should gradually wind down overnight Saturday night into Sunday morning, leaving behind mostly dry conditions by Sunday afternoon (except possibly our far east).

QPF amounts haven't changed much, still generally thinking a good 1 to 1.5". Although will likely be less than that across western portions of the region from the Ozark Foothills northeast into portions of southwest Illinois (closer to Mt Vernon). Meanwhile, localized higher amounts pushing 2" or slightly higher remain possible, particularly across west KY. If the system trends stronger into a major hurricane at landfall, then it's possible rainfall amounts trend higher and overachieve again which would lend to a greater flooding concern.

850-925mb winds continue to look quite strong as the remnants of Isaias push north into the TN Valley on Saturday. However, a stable layer near the surface may keep the strongest winds from mixing down as it approaches our cwa. For now, generally think wind gusts of 25- 35 mph (highest near KY/TN border), are the most probable outcome Saturday afternoon and evening. Certainly still possible for wind advisory level gusts of 40+ mph, probably would put that around 20- 30% chance of happening.

Upper level ridging builds back in early next week, which will allow highs to return to the 80s Monday and possibly Tuesday. A backdoor front (likely dry) drops through on Tuesday though which will allow cooler air to filter in mid week.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 535 AM CDT Thu Oct 8 2026

Winds will become east-northeasterly around 4-7 kts today behind a weak frontal boundary that pushed through overnight. Some patchy shallow fog is possible through 13z and again late tonight, mainly impacting KCGI and KMVN.
