Strong Front This Weekend Delivers Surge Of Heat, Storms, Then Blast Of Unseasonably Cool Air…

Updated 05.17.22 @ 7:26a

While we’ll have to deal with showers and storms Wednesday (could have a couple strong cells across southern Indiana), the big deal of the short-term forecast package centers on a strong cold front that will blow through the area this weekend. Ahead of the front, a brief surge of significant heat and humidity will push into town as we wrap up the work week. Friday looks particularly oppressive as heat and humidity combine to push “feels like” temperatures into the lower 90s for many.

While we’ll have to fine tune timing and deal with the all-important specifics (are we having to deal with cloud cover that could limit instability?) as we get closer, the Storm Prediction Center continues to highlight western and northwestern Indiana in a risk of severe weather Friday. (Most of the storms should impact our state Friday night- still think the majority of the day time will be free of any storms).

As low pressure heads for the Great Lakes and drags a cold front through our region, it wouldn’t surprise me if the SPC hoists an additional risk of severe weather Saturday. Saturday afternoon into predawn Sunday is expected to offer up the most widespread coverage of rain and storms, locally.

Once the front is off to our east, a MUCH different airmass will blow into town, courtesy of a gusty northwest breeze. We’re talking about highs only in the 60s early next week with lows into the 40s. Talk about a breath of fresh air after the heat and humidity to close the week!

Dry weather should prevail Monday before a new system offers up a soaking Tuesday PM into Wednesday.

Monitoring Monday’s Storm Threat…

Updated 10.09.21 @ 9:30a

After a mostly dry, sunny, and unseasonably warm weekend, our next storm system will approach as we kick off the work week. Southerly winds will usher in an unseasonably moist airmass to combine with August-like temperatures (highs once again are expected to shoot into the lower and middle 80s).

Southerly winds will transport unseasonably muggy air north Monday. South winds will gust 30-35 MPH at times.
Dew points will climb into the middle and upper 60s ahead of the approaching cold front Monday.

The Storm Prediction Center (SPC) outlines the western Ohio Valley, including most of Indiana, into the central Great Lakes region for a Slight Risk of severe weather Monday.

A surface wave is expected to develop along the pressing cold front Sunday evening and track northeast into the Great Lakes. After a warm, dry, and breezy start to Monday, a line of thunderstorms should develop late Monday morning or early afternoon across western IL. This line will then track east and move into Indiana during the late afternoon and evening hours.

Given some of the ingredients in place, the primary concern with this line of storms will be the potential of damaging straight line winds. There also is the potential of a couple rotating storms within this overall line of storms that could pose an isolated tornado threat.

After the stormy time of things Monday PM (rainfall amounts should check-in between 0.50″ and 1″ for most), conditions will improve as we move through the day Tuesday. Another (weaker) system will push into the area midweek, but as of now this doesn’t look like a significant event.

A stronger cold front will arrive to close the week with more widespread rain. After an unseasonably warm stretch, cooler air should finally filter into the region next weekend.
