“Jack Frost” Visits Tonight

A strong cold front will bring us the coldest air so far this season.

Before the front arrives, temperatures are starting out well into the 60s.

Showers and thunderstorms will become more widespread as Wednesday progresses.  Those showers will exit early this evening with clearing skies overnight.

With diminishing winds tonight, lows will drop to around 30° across our far northern hometowns and into the low-to-mid-30s in the Quad Cities.


A “Frost Advisory” and “Freeze Warning” has been issued for much of eastern Iowa and parts of northwestern Illinois Wednesday from 2-9 a.m.   

If you have some plants you want to save, you’ll want to cover them this evening or bring them indoors.


Freezing Temperatures Sunday Morning

Brrrrrrrrrrrrrrr!  You’d better pull out those long-johns and if you don’t think they’re sexy and you refuse to wear them, you’d better get some extra blankets.

A “Freeze Watch” (dark blue shading) is in effect late Saturday night until 8 a.m. Sunday for central and eastern Iowa and the counties along the Mississippi River in Illinois.

This means that we’ll be seeing several hours with temperatures at or below the freezing mark (32°) early Sunday morning.  This will likely bring an end to the growing season across the Mississippi Valley.  Any plants that are not brought inside and left outside uncovered will likely freeze.

Even if temperatures don’t drop below 32° where you live, frost will occur!

As we get closer to Saturday night, this “Freeze Watch” may be upgraded to a “Freeze Warning” or a “Frost Advisory” for areas south and east of the current watch.

Temperatures early Sunday morning will range from around 27° north to around 32° in the Quad Cities to around 35° in the far south.

After that very cold weather, warmer temperatures return next week!

I will have to suffer through this because I refuse to turn the heat on until October!


It’s Almost Fall & It’s Getting Colder

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.
