Storms could bring strong winds to central Illinois on Tuesday evening

Peoria, Illinois (WMBD) — A line of storms known as the Derecho, leaving widespread wind damage in its wake, is currently roaring through Iowa and is expected to move into Illinois late tonight. Although the storms are likely to weaken a bit as they move through the region, they still have the potential to bring damaging gusty winds to central Illinois after midnight.

Key points to remember

  • Severe storm: 12:00 a.m. to 4:00 a.m. Wednesday
  • Main threat: damaging wind gusts up to 65 MPH
  • Storms will likely produce frequent lightning and heavy rain

Tracking the evolution of mesoscale convective systems, such as Derechos, is difficult enough; but another thing that could further complicate the path of these storms are new storms developing along the locked front that stretches from Chicago, IL to La Crosse, WI. These storms could cause the incoming squall line to do one of two things…

  1. Weakening as it interacts with cold winds out of developing storms ahead of it, but still brings a loosely organized group of storms to central Illinois.
  2. Maintain your strength and be redirected southeast into central Illinois.

Both solutions result in increased storm coverage after midnight in central Illinois, but the second solution would result in more widespread extreme weather, particularly wind damage, throughout the region. The Storm Prediction Center has a slight risk (Threat Level 2) over central and northern Illinois for severe storms tonight, primarily between midnight and 4 a.m. in our area.

A severe thunderstorm watch has been issued for Henry, Bureau and Putnam counties through midnight tonight, although additional watches or an extension to the current watch may arrive later tonight depending on how the weather develops. derecho.

This includes a NOAA weather radio that can wake you up while you sleep so you can take cover.
