After our grueling summer of sweltering under a "heat dome" that wouldn't go away, a cold front is forecast to arrive this weekend and usher in much more pleasant weather.
It might be a little too early to declare victory against heat and humidity, but the medium-range forecasts are suggesting that this cooldown will actually stick around. The 6-10 day outlook shows that we have a very good chance of seeing below-average temperatures:
The one-month outlook for September doesn't draw any firm conclusions, but at least it doesn't forecast a major heat wave, unlike previous monthly projections.
This long-awaited cold front isn't likely to bring much rainfall. That's good news for the holiday weekend, but bad news for our near-drought conditions. According to the U.S. Drought Monitor, the Cape Girardeau area is not technically within a drought (we're only "abnormally dry"), but the seasonal outlook shows that drought development is likely from Cape Girardeau southward.
The old saying "It always rains during fair week" was proven false last year, and, judging by current trends, could be false again this year.
One question mark is Tropical Storm Lee, a blob that is currently meandering around the Gulf of Mexico. It appears that Lee will strike Louisiana and then pull off to the northeast, completely missing us. However, these weak Gulf storms have a tendency to make unexpected turns, so it's not out of the question that we could see some action from the remnants of this tropical system.
