Cool and Fall-like For The Weekend, But Warmer Days May Still Be Ahead

September 13, 2013 0 Comments

After a week of above normal temperatures, our weather pattern has again shifted and cool, dry, autumn-like weather is invading the region from the north.  Strong high pressure is providing us with an absolutely gorgeous, sun filled Friday that features not only crisp dryness and bright sunshine, but also very light winds.  A similar scenario at the tail end of Labor Day weekend brought us some of the coolest temperatures of the season ten days ago and again this morning we woke up to 30s and 40s across the entire area reminding us that fall isn’t far off.  In fact, this current batch of cooler air looks to stick around through the weekend, bringing us chances for similar morning temperatures Saturday morning and Monday morning before warmer air slides in for a while.  A storm system from the southwest will interrupt the string of cool day this weekend as much-needed rain and the accompanying cloud cover Saturday night through the first half of Sunday will keep overnight temperatures from dropping a great deal.

This pattern will last through the first part of next week before the jet stream looks to flatten out, allowing for slightly warmer air into the Upper Midwest while the “zonal” flow pattern makes for a more active weather pattern, possibly introducing more rainfall opportunities to our area for the longer term this month.

The jet stream has buckled southward in the eastern half of the country, allowing cooler, more fall-like air into the Great Lakes and Upper Mississippi Valley regions.

A flatter, more zonal flow pattern aloft next week may mean more rain chances in the next week or two for us, possibly alleviating some of our drought issues.
