Severe t’storm threat today/tonight… ⛈️

✔️ Scattered showers and t’storms will develop this afternoon, along a frontal boundary pressing in across Northern Illinois on down into Missouri. This activity may congeal into loose clusters, then affecting Northern and Central Illinois from this afternoon through tonight. Severe t’storms may be possible with some of this activity. A level 1 to 2 severe t’storm threat is in place across much of Northern and Central Illinois, for the threat of isolated to widely scattered severe t’storms. Damaging winds will be the main threat with activity.

Severe t’storm threat returns on Thursday… ⛈️

✔️ Thursday/Thursday Night… A weakening cluster of rain/t’storms may move into/across Northwestern Illinois on Thursday morning. In the wake of this activity, as a frontal boundary presses in across the northern half of the state and a few disturbances move through the area, scattered showers and t’storms will develop on Thursday afternoon across Northern Illinois. This activity may congeal into loose clusters, then affecting Northern and Central Illinois from Thursday afternoon through Thursday night. Severe t’storms may be possible with some of this activity. A level 1 severe t’storm threat is in place across portions of Northern and Central Illinois, for the threat of isolated severe t’storms. Damaging winds will be the main threat with activity.

Widespread hot & humid conditions continue on Thursday… 🔥🥵

Hot and humid conditions can once again be expected across a large portion of the state on Thursday. High temperatures will range from the upper 80’s to upper 90’s, with the heat index values of 100-115° expected.

The one exception will be across Northwestern Illinois and vicinity, where both high temperatures and heat index values will be a bit “cooler”.

Hot & humid conditions expand on Wednesday… 🔥🥵

Hot and humid Tuesday for some…

Hot and humid conditions will begin to invade portions of the state today, mainly across Western, Southwestern and Southern Illinois. Across this corridor, high temperatures around 90° or in the lower 90°’s can be expected. Of more focus will be the heat index, with values of 99-108° expected within this corridor.

Take a look at these pictures of funnel clouds that occurred across portions of Central Illinois this afternoon and evening!

This was a similar situation as what occurred yesterday, in which environmental conditions were favorable for these funnel clouds to develop.

Also similar to yesterday, there has not been any confirmation that there were any touchdowns. However, if you have any evidence that one did touchdown, let us know!

Heat & humidity on the way... 🔥🥵

A high pressure ridge that is in place across the CONUS will expand northward and strengthen for a time, leading to a setup favorable for a period featuring hot and humid conditions across the state.

✔️High temperatures in upper 80°'s to mid 90°'s will be likely across different portions of the state on different days.

✔️With evapotranspiration (corn sweat) season in full swing, moist air will be in place across the area, in the form of dew points in the 70°'s. These moisture values, combined with the hot temperatures, will lead to the likelihood of heat index values of 100-115° across different portions of the state on different days.

✔️Little relief will occur at night across the state, with overnight low temperatures in the 70°'s and elevated heat index values continuing. Urban metro areas (Chicago/St. Louis) may flirt with overnight low temperatures near 80° on some nights.

✔️Daily record overnight low max temperatures will be in jeopardy of being tied or broken across the state for some of the dates during this period.

✔️As another ‘Ring of Fire’ pattern sets up later in the week, there will be a daily chance of rain/t’storms, and perhaps severe t’storms, across portions of the state. This will alleviate conditions for some areas.

✔️It is possible that hot and humid conditions may persist across portions of the state into the weekend and perhaps into next week as well. Should this occur, we will have another full update.

Part 1 of the ‘ring of fire’ weather pattern has come to an end, after an active weekend, with repeated rounds of rain/t’storms across the state. ⛈️

Part 2 comes later this week and through the weekend.
