KEY MESSAGES

- One more hot and humid day expected today with highs in the low 90s and heat index readings ranging from 100 to 105. It will also be quite breezy with southwest winds gusting 20 to 30 mph. A Lake Wind Advisory is in effect.

- Showers and storms accompany a cold frontal passage late this evening through the night, primarily exiting our area by Friday morning. The overall severe threat is fairly low, but a few stronger storms could produce pockets of damaging winds along with brief heavy rainfall.

- Drier air works in on Friday with much lower humidity and cooler temperatures.

- Soupy conditions return Saturday afternoon and may linger into Sunday. Another round of showers and storms appears likely Saturday into Saturday night, and this may linger into at least the first half of Sunday. A few stronger storms are possible which includes the threat for heavy rainfall and flash flooding.

- Early next week is trending cooler and less humid. There is a 70-90% chance at dew points remaining below 60 degrees on Monday and Tuesday! This appears short-lived though as higher humidity and warmer temperatures look to return later in the week.

DISCUSSION

Issued at 1237 AM CDT Thu Jun 11 2026

An upper trough ejecting across the Great Lakes will send a cold front through the Quad State region tonight. The main forcing (and stronger wind shear) will remain well north of our region. The main line of convection likely won't reach our cwa until after 02-03z (late evening and overnight) when instability will be waning as well. May still have around 1500 j/kg or so to play with for a bit though. Thus, its possible a few storms may intensify to severe levels with mainly a damaging wind threat. But overall looks pretty low end. Can't rule out some localized flooding concerns, but seems the line should be progressive enough to largely prevent any issues.

Should see lingering convection exit west KY Friday morning, with high pressure building in helping to usher in much lower humidity (dew points in the upper 50s to low 60s by afternoon)! This will be short-lived though as the front to our south will push back north on Saturday with soupy conditions returning to southeast Missouri first and eventually the entire area through the afternoon. Models are hinting at a shortwave disturbance traversing the MO valley into the lower Ohio Valley Saturday afternoon and evening. This may lead to a bit of an uptick in wind shear which combined with the instability gradient laid out across our area could result in a few strong to severe storms. Also appears an ideal setup for some training convection which could result in some flash flooding concerns as well. The window looks to be anywhere from Saturday afternoon through the night. Some of this could linger into Sunday morning, but the general trend is a bit drier on Sunday, especially by afternoon.

Another shot of cooler, drier air looks to filter into the area early next week. LREF guidance has a 70-90% chance at dew points remaining below 60 on both Monday and Tuesday. High temperatures may struggle to hit 80 on Monday and only be a few degrees warmer on Tuesday. While there is some uncertainty with PoPs during this time, it does appear the main threat will be south of our cwa. Southerly flow looks to usher in warmer temperatures and a return of higher humidity by the latter half of next week. LREF shows a 50% chance at temperatures hitting 90 again across southeast Missouri next Thursday and Friday.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 604 AM CDT Thu Jun 11 2026

Decaying band of convection across our northern terminals will dissipate within a few hours. Rest of the daytime looks dry with only some SCT to at times BKN cu. Southwesterly winds will increase this morning, becoming sustained 10-18 kts with gusts up to 25 kts. A cold front makes passage tonight, accompanied by a broken band of showers and thunderstorms. This activity looks to move in to the northwest around or shortly after 02z and should clear our southeast counties by 12z Friday. May see some brief MVFR cigs and vsby restrictions with heavier convection, but otherwise largely VFR conditions expected. Winds become northwesterly overnight into Friday morning.
