ROCKFORD (WREX) — It's back to fall weather for the rest of the week thanks to cooler air flowing in. The warmth doesn't leave for long, and could be back when fall officially kicks off.
Cool end to the week:
2 cold fronts pass through by Thursday morning, dropping temperatures 15 degrees. The result: temperatures back down into the upper 60's after 2 days in the 80's. Breezy northeast winds will add a little to the chill in the air Thursday. The weather remains sunny (and a little hazy due to the wildfire smoke).
By Friday, we settle into the middle 60's, or a couple degrees cooler than Thursday. Because cool and dense air promotes sinking through the atmosphere, the haze may be gone for a day. The sinking air helps "wash" the sky of the smoke, resulting in clearer conditions.
Over the weekend, the weather warms up a little but remains in the 60's. We'll be closer to 70 degrees, however, thanks to the slight warming trend. The sky remains sunny and dry, but watch for a new round of haze to move in due to the wildfires.
Warmer next week:
A warm front arrives Monday, and gives temperatures a boost. Temperatures return to the low to middle 70's through all of next week. This front won't bring anything more than a few clouds, as rain and storms stay to the north. We keep the sunshine in the forecast possibly through next weekend.
This long stretch of dry and sunny weather may raise new drought concerns. While some spots saw over 6" of rain last week, areas south of US 20 fell short of that mark and need more. Last week's rain was very beneficial but not quite enough to remove abnormally dry conditions from the Stateline. The dry weather may last into the end of the month, and could cause some spots to slide back into drought conditions.
