Sizzling Independence Day Before Weekend Relief…
A hot and humid Independence Day awaits with minimal storm coverage this afternoon. While an isolated storm is possible, overall storm coverage will be significantly less than Tuesday afternoon. The big story will be heat indices approaching 100° to 105° this afternoon. If you have plans outdoors today, hopefully it’s by a pool!
As we move into Thursday, a cold front will approach from the north. Ahead of this boundary, the potential is present for a gusty round of storms Thursday afternoon and evening.
The Storm Prediction Center currently has a ‘Marginal’ risk of severe weather for portions of the state. It wouldn’t surprise us if a portion of this risk area is upgraded to a ‘Slight’ risk with future updates. The primary concerns? Stronger storms may include damaging winds and large hail.
Storm coverage will diminish during the day Friday with a drier air mass taking hold by evening. We’ll really notice a reduction in humidity Friday night and that more refreshing feel will remain intact through the weekend. Dew points may even fall into the 40s by Saturday morning! Many central Indiana neighborhoods can expect to settle into the mid and upper 50s for overnight lows Saturday and Sunday mornings.
Dry weather will be with us as high pressure remains in control of the period this weekend into early next week.
Longer term, a transition period should take place around the middle of July that should ultimately help set up a cooler close to the month and open to August- relative to normal and certainly to where we’ve been lately.

NEW JMA Weeklies Shed Light On The Long Range…
Changes are brewing in the longer range and the latest JMA Weeklies illustrate this nicely.
Week 1
No changes are needed to the expected significant heat wave to open the month of July. Heat and humidity will reach excessive levels at times- heat indices of 100° to 110° at times. While isolated coverage of storms are possible a few of the days (primarily afternoon and evening variety), it’s a dry pattern, overall.
Week 2
The pattern is in a transitional period during this time frame as the upper ridge retrogrades west. While still warm, the hottest conditions will shift west under the upper ridge. The other take-away? An active northwest flow returns with an emerging “ring of fire” pattern.
Weeks 3-4
While perhaps a bit quick, the model reverses things entirely by the Weeks 3-4 time frame. There’s no denying we think the hottest period of the summer will be behind us by mid-July, and while this type pattern shown below is where we think the dominant overall pattern is heading for the second half of summer, the model may be a bit aggressive here. Regardless, the Weeks 3-4 time frame are expected to not only reverse, but turn cooler than average over the Great Lakes region.
