Wednesday starts out quiet, then strong storms may make an appearance

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) — With summer heat returning to the Stateline, strong to severe storms may follow. The timing of the storms may impact how severe they get, but be ready for potentially wild weather as we get closer to Thursday.

Quiet day:

Leading up to the evening storms, midweek looks and feels like a typical summer day. Wednesday starts out sunny, with temperatures rising quickly. We jump back into the upper 80's by the afternoon. Conditions may feel like the low 90s thanks to the higher humidity. The added heat and humidity boosts the instability in the atmosphere, leading to more energy for stronger storms later in the day.

At the earliest, storms may arrive around dinner time Wednesday. This depends on how quickly they get going to our north and east. There is a low risk for severe weather during this time frame. Additional storms fire up Wednesday night, which may be the best chance for severe weather for us.

Stormy night:

Strong to severe storms are likely Wednesday afternoon in Wisconsin and Iowa. Those storms move into our area by Wednesday night. The risk for our area is lower, however, due to the timing of the storms.

The overnight round of storms brings damaging wind and flash flooding threats, along with low hail and tornado risks. These likely move in after midnight.

That said, the timing of these storms may work against them. There's less energy to work with than during the day, when the sun heats up the air plenty. As a result, we may see a few strong storms and avoid severe weather. If they are able to hold together, be ready for the threats listed above. Have a way to get alerts overnight, like a weather radio.

Damaging winds and flash flooding are the main threats for Wednesday night.

Storms may continue on and off through Thursday morning, which raises the flash flooding threat. Multiple rounds of downpours in the same spots results in hefty rain totals, so avoid any flooded roads that you may see during the Thursday morning commute.

A marginal risk for severe storms is possible south of the I-88 corridor Thursday afternoon.

More storms may break out Thursday afternoon, depending on how the early morning storms behave. The best chance for a second round of strong storms looks to be near and south of the I-88 corridor Thursday afternoon. Once we get beyond Thursday, rain may be hard to come by.

Quiet stretch begins:

The weather settles down after Friday morning. A storm may linger early, but for the most part Friday starts to dry out. Look for mostly sunny weather with highs in the low 80s.

This kind of weather could last through this weekend and possibly through next week as well. Temperatures may vary a little and occasionally get into the upper 80s, but for the most part get ready for at least 7 days in a row with sunshine.
