ROCKFORD (WREX) — An active jet stream pattern is working into the Stateline for the next several days. This will give us the chance to see rainfall and cooler fall-like highs.
The first thing we will notice is the rainfall that has moved into the Stateline after weeks of mostly dry conditions. Starting in the morning, the Stateline will remain dry but cloudy. Temperatures will rise into the '70s and winds gusting up to 15 MPH. The rain chances will arrive along a cold front that will push through the Stateline by the afternoon. Will there be any kind of severe weather? No, we should just see a few showers in the region. There will not even be any thunder expected with the showers that move. Rainfall amounts will be around 1/2" for the entire Stateline. Showers continue into Monday, but chances remain scattered.
There will be a change in temperatures during this front passage as we quickly fall into the '60s upon its arrival. This will start a trend toward cooler nights and cooler days. Lows for Sunday night will make it down into the upper 40's and lower 50's.
Highs on Monday start the fall-like feel that many expected when fall started. Temperatures will stay around the lower 60's for the entire start of the workweek after Sunday's cold front passage. However, we will see even lower temperatures are our jet stream digs deeper into the Mid-West. This will bring temperatures down even more into the '50s heading into the next weekend.
Despite all the feel, we are actually going to be well-below average for temperatures for the next several days. The average highs for late September and Early October are in the upper 60's and lower 70's. Taking this into consideration brings highs nearly 15-20° below average highs through the next week.
