Key Points – Tuesday, October 11, 2016 – early next week


Good Tuesday morning and thanks for taking the time check out the latest Zones 3/4 update! First glance at radar this morning shows a cluster of storms moving west to east near the Iowa/Illinois border; this cluster could bring moderate to heavy showers as it passes east to northeast before dissipating.

Showers and maybe a thunderstorm will continue to move east across Zone 4 this morning before dissipating. Otherwise, it should be a nice, mild day with a mix of sun and clouds across both Zones. Our next opportunity for showers and storms comes Wednesday afternoon/evening into Thursday morning with the passage of a cold front. A few of these storms have potential to bring some gusty winds and some small hail, so that’s worth a mention 24+ hours out.

Transitioning our focus over to potential frost, you can see in the images below that both Thursday and Friday mornings have the opportunity to bring frost-like temps to mainly Zone 4…but possibly northern Zone 3 has potential as well.

Another decent shot of showers and maybe a few storms comes Sunday as another cold front moves through.

Confidence and Risk:

  • We have high confidence showers persist east before dissipating across Zone 4
  • We have high confidence a mix of sun and clouds will be possible today
  • We have high confidence in a cold front pushing east Wednesday into Thursday morning across both Zones with potential gusty winds and small hail
  • We have above average confidence in another cold front pushing through Sunday morning across the Zones bringing additional shower/storm coverage across the Zones
