Warm But Changes On the Way

The strong ridge that has dominated our upper air pattern for several days will begin to break down today as a trough and associated cold front in the Central U.S. progresses eastward. However, our ridge will last just long enough to allow temperatures to spike upwards today. With 850 mb temperatures near 15 C, highs should top out near 85 F today. A surface high pressure system slides to the east of us today and will shift the winds to the southeast that will usher in more moisture into the state. This increase in moisture will be noticed at all levels in the troposphere and will likely result in increasing clouds later this afternoon. These clouds will thicken and lower as we move through the overnight hours and should keep temperatures tomorrow morning in the mid 60s.

A weakning cold front approaches the state tomorrow and will increase our ran chances. However, with the weakening nature of the front, I don't expect any severe weather or heavy rain. This front will bring a swift change in temperatures from Friday through the weekend. With highs in the 70s and lows in the 40s, it will certainly feel like fall!
