TONIGHT: Mostly clear and mild with lows in the upper 50s to around 60. Patchy fog in river valleys.
TOMORROW: Partly to mostly sunny and hot with highs in the mid-80s.
EXTENDED: A warm week is expected with temperatures rising 5-10 degrees above average each day, with some small nuances to make each day different. Another mild night is expected as temperatures drop into the upper 50s to around 60 tonight. We'll see some patchy fog in river valleys, but we're otherwise sunny for Tuesday morning. An area of low pressure is expected to push into the Wisconsin/northern Illinois region on Tuesday, dragging a weak front through Mid-Missouri between Tuesday night and Wednesday. The low level jet stream picks up after sunset on Tuesday, enhancing the moisture and lift along this boundary to get scattered storms going after about 10:00 PM into Wednesday morning. I'm expecting less than a quarter inch of rain, and any severe threat stays to our northeast. Clouds retreat on Wednesday, but temperatures will be slightly cooler in response to morning showers. The rest of the week will be unseasonably warm as we're trapped in a blocking pattern with low pressure to our west and a tropical system keeping warm high pressure locked in over the Midwest. Highs reach the low to mid-80s on into next week, with little cloud cover or rain to speak of.
