Key Points – Friday, October 7, 2016 – early next week


Good morning and thanks for checking out Friday’s edition of the Zones 3/4 forecast update! Taking a first glance at regional radar this morning, we can see a continued weakening trend of showers and storms as our cold front pushes east.

Yesterday we believed this line “could” persist near the IA/IL border…it got close, but fizzled out a little earlier than we originally thought. With that being said, there were numerous severe reports, including tornadoes, right near the border!

You can see from our strong storm risk area yesterday, that these verified very well!

We have average confidence that a skinny line of showers is possible as our cold front pushes east through the Zones today. This will be possible this afternoon through this evening across both Zones.

Our weather will be trending slightly cooler as we head into the weekend. Checking out the latest temperature/dew point spread across the region, you can see the relief almost instantly as the cold front passes. Areas west are already seeing temps in the 40s and dew points in the 30s and even 20s, while right now both Zones are still in the 60s with similar dew points.

Conditions will be very pleasant and temperatures will be comfortable (at least a lot more comfortable than this past week!) Saturday and Sunday across both Zones due to high pressure moving in and taking control of our weather; temperatures will be near-normal across most locations.

(High pressure brings in welcomed pleasant conditions)


Our next chance for showers will come early next week…right now our models suggest a cold front to push through Zones 4 and 3 Tuesday into Wednesday next week. Widespread precipitation is not expected at this time, confidence right now with this front is about average as to coverage and timing.

Thanks for checking out Friday’s Zones 3/4 update, we will be bringing you additional updates this afternoon and into the weekend in regards to upcoming inclement weather.
