Autumn arrives this upcoming Friday but you sure wouldn't know it with the forecast that lies ahead of us here in the Sauk Valley.
A warm front combined with a disturbance passing to the northwest of the area later this evening into the overnight will provide our only solid chances for some much needed rainfall across our area. Coverage on these storms isn't expected to be all that great and no severe weather is currently anticipated. The timing for the rain appears to be after 6pm through much of the overnight hours.
Once the front moves through our moisture levels will dramatically increase by the middle of the week. Tuesday you'll be able to feel the increased humidity as our dew points rise into the uncomfortable level before jumping to more oppressive levels by Wednesday. These increasing moisture levels will also be accompanied by well above average temperatures reaching for 90 by Wednesday.
A strong area of high pressure will keep rain chances limited with isolated coverage of showers and storms possible Tuesday and Wednesday as temperatures soar well into the 80s close to 90. Better rain chances currently exist just to the west of the area for much of this week. Areas across central Iowa still remain in drought and also need the rain, too!
If this forecast holds true I would not be surprised to see our drought level upgraded by the end of this week as our rainfall deficit will continue to grow.
