You knew it wouldn't last much longer. Our temperatures since the weekend have been well above normal. Wednesday will continue that trend. As a strong low pressure system and attendant cold front steam in our direction out of the Great Basin, our southerly winds will drive temperatures well into the 70s. Winds will gust in excess of 30 mph at times. Wednesday night into Thursday morning we will see a chance of showers and thunderstorms. This is a fairly dynamic system so it will bring a slight risk of severe storms with it as it moves through St. Louis early Thursday.
Temperatures should be in the 50s early Thursday and hold there before dropping rather rapidly Thursday afternoon into Thursday night. Friday through the weekend will be chilly with overnight lows in the 30s and daytime highs in the 40s. Add a brisk wind to that and it should make for a fairly raw weekend.
There is a chane for some more rain the first part of next week and keep in mind, we are on-track for the wettest year on record in St. Louis. As of today, 11/4, we are 3.42 inches shy of the all-time record.
We may have seen the last of the mild weather for a while. The extended outlook from the Climate Prediction Center has an above normal chance for below normal temperatures across our viewing area.
