Welcome to fall in Missouri, where we have to worry about the heat index and the wind chill factor in the same week.
Our record heat wave will soon be replaced by below-normal temperatures. And a sudden change in temperatures this time of year usually means one thing: strong thunderstorms.
Indeed, we're at the edge of a Slight Risk zone for severe thunderstorms for Wednesday.
The forecasters at the Storm Prediction Center are concerned about the possibility that a few supercells could develop and bring large hail and high winds. Since we haven't seen much thunderstorm activity in recent months, this could be a bit of a shock.
Another shock will be the new air mass that arrives later this week. Overnight temperatures on Thursday and Friday will plummet into the mid 40s -- quite a difference from what we've experienced lately, but not quite cold enough to worry about frost. Yet.
We set two record highs this week at Cape Girardeau. Today brought a high of 85 that tied a record last set in 1963. Yesterday saw a high of 87 that tied a record from 1965.
At least this wasn't as extreme as St. Louis, which reached 91 at Lambert Airport yesterday, toppling the old record of 88 set in 1950.
