Heat Wave & Active Storm Pattern For Mid-July

(5:00PM - 7/12/20) A hot, humid and stormy pattern is set to take hold for mid-July across the state and region.

​A hot, humid and stormy pattern is expected to settle into the region the middle of this upcoming week, with it expected to continue through next weekend, and likely well into the following week. This pattern will be characterized by an elongated ridge across much of the country. This will lead to a reservoir of hot and humid temperatures for a large portion of the country, including portions of the state. North of this large ridge will be an active jet stream, which will lead to numerous rain/t'storm and severe t'storm chances for the region and portions of the state. At this time the most consistently hot and hottest temperatures for the state during this period will be across Southern Illinois. Across this area temperatures well into the 90's will be common, with even the potential for temperatures into the 100's if conditions set up perfectly. Humidity and heat indices will also be high, with heat indices well into the 90's and 100's. Further north across Central and Northern Illinois, hot temperatures into the 90's will be likely at times, whenever the ridge flexes north. However, across these areas there will be numerous times that the heat is tempered due to the expected active rain/t'storm and severe t'storm pattern.

Additional updates for this period will be needed over the coming days.
