Another Round of Scattered Storms

Much like we witnessed on Friday, scattered showers and thunderstorms will dot the radar again on Sunday.  There are some differences in the forecast, however.  With a fast-moving cold front expected to slide through the area early in the day, there will be a limited amount of time for the sun to warm things up before cloudcover and the threat for rain arrives.  Our high temperatures will likely climb into the middle 80s—perhaps only near 80 in southwestern Wisconsin, where the effects of the front will strike first.

A broken line of showers and thunderstorms will develop along and ahead of the front and push southeast through the region.  FutureTrack depicts this potential line of storms entering the Rockford metro around 1pm.  It appears that some areas well west of Rockford could pick up a shower or two before the afternoon hours.  Moisture is more limited with this system, compared to Friday, so not all areas will see rainfall.  Chance of rain is 50%, so some backyards will remain dry on Sunday.

The threat for strong thunderstorms exists.  However, given the swift speed of the cold front, the best chance for any severe weather appears to be just south and southeast of our local area.  Central Illinois and parts of Indiana will have more time to warm up on Sunday, creating an atmosphere primed for a few stronger thunderstorms.  The main threats Sunday will once again be hail and gusty wind.  Excessive rainfall, like we saw on Friday, is less of a threat due to the fast-moving nature of the front and associated thunderstorms.  If your travels take you to Bloomington-Normal, Peoria, Champaign, or Indianapolis, keep an eye on the sky.
