Although we’ve already experienced some chilly weather, we’re still a few days away from the official start of fall. Autumn begins in the Quad Cities Saturday, September 22, 2012, at 9:49 a.m.
While we saw a high of 86° last week, it’s going to be some time before we get to enjoy temperatures like that again thanks to a series of cold fronts that will give us sporadic chances of rain and the coldest air of the summer and fall.
I added summer in there because since it’s technically still summer and we’ll be dropping into the 30s tonight across the Mississippi and Illinois Valleys.
We’ve already had several mornings recently with lows in the 40s, but we officially haven’t had a low temperatures in the 30s in the Quad Cities since April 27, 2012, when we dropped to 36°.
After a chilly Tuesday with highs in the low-60s, we’ll warm back into the 70s Wednesday and Thursday as we await our next cold front. That will bring some light rain Thursday night and Friday.
When that strong cold front passes through Friday, high pressure from Canada builds into the Midwest Saturday. This will give us a mostly sunny start to the day with increasing afternoon clouds and a chance of some chilly rain showers. Skies clear out Saturday night and we could be seeing low temperatures Sunday morning in the low-to-mid-30s.
Frost will be likely on the scarce pumpkins (the dry, hot summer weather produced a shortage across Illinois) Sunday morning.
The last time we saw a freezing low temperature in the Quad Cities was 32° on April 23, 2012. On April 12, 2012, we dropped to 28°, which is cold enough to be called a “hard freeze”.
The cooler than average temperatures will pretty much dominate our weather for the rest of September. That doesn’t mean we won’t see mild days ahead of cold fronts, but for the most part, it will be cooler. The Climate Prediction Center agrees.
Have a great rest of the weekend and enjoy the last few days of summer.
