St. Louis forecast: Still summer-like through midweek

Showers, some thunder likely late Wednesday into Thursday with much cooler temperatures.

ST. LOUIS — Our temperatures have been well above average through the month of September and the first few days of October this pattern continues.  Our average high temperature this time of year is in the mid 70s and our highs will be about 10-15 degrees above average through Wednesday. 

A cold front is set to arrive Wednesday night/AM Thursday and another one Thursday night/AM Friday. This will bring us our next opportunity for rain and a big seasonal shift. With the two cold fronts pushing through the area, we are hoping to see .25" to .75" of rain and we will see a dramatic cool down in our temperatures. Morning lows in the 40s and afternoon highs in the 60s are expected next weekend.
