Summer-like morning underway with air temps in the low to mid 70s and southerly breezes. Severe weather ongoing across the plains...with a squall line approaching the St. Louis metro area early this morning.
For the most part our region should stay just to the east of the active weather today, though a weakening line or two or showers/storms may brush our northwestern most counties this morning....particularly near Farmington/Ste. Genevieve/Sparta/Mt. Vernon etc.
A few isolated strong storms may pop in other areas this afternoon or evening...but better chance of active weather will develop tonight into Tuesday as the pattern shifts slowly east and weakens.
The Heartland is on southwestern edge of slight risk area today/tonight...and in center of slight risk area for tomorrow. Limiting factor tomorrow may be clouds keeping temps down a bit...but if we get much sunshine watch out.
Showers and T'storms look to linger into early Wednesday...at which point we'll get a 3 or 4 day period of quiet, cooler and less humid weather to round out the week. Coolest days look to be Thursday thru about Saturday...along with lower dewpoints. By the end of the weekend and into next gradual warming is likely again as we ridge out again...but indications are that the weather will stay more tranquil at least into early next week.
