If you would like to be notified when the expedition video stream goes live, follow the Facebook or Twitter feeds.

Posted Tuesday at 2:00PM: An expedition in an excessively convenient target is about to get under way. I will be activating my live streaming camera shortly - when that occurs, I'll post a quick notification blurb to the Facebook or Twitter feeds. Or, you can simply check back periodically at the Live streaming video page - if there is a little vehicle icon present, it means my video stream is active.

Posted Monday at 10:24AM: Spring storm season in the Midwest continues to ramp up with another wave of significant severe weather affecting the region. For today (Monday), a combination of instability, strong upper-level winds and directional wind shear will provide potential for severe storms mainly south of St. Louis around sunset. These storms should move across the metro area overnight, with a possible lightning show.

Tuesday brings the threat for a serious outbreak of tornadoes across the region. Strong instability, fast winds through the upper to low levels, a surface low in the vicinity and a warm front will provide focus for supercells. Directional shear is supportive of tornadoes.
