Classic Plains Tornado Outbreak Ingredients

Sadly, given the events in Joplin, Mo. and Minneapolis this past weekend, we are not through with severe weather this week. Not by a longshot.

The ingredients are in place for a classic Plains tornado outbreak Tuesday. Let's step through the reasons for this, followed by our latest severe weather outlook.

Moisture: Check!

First, you need rich low-level moisture to provide fuel for thunderstorms. Below is a current dew point map of the Plains showing surface moisture values. Values in the 50s are considered a minimum bound for significant severe t-storm development. Dew points in the 60s and 70s indicate more muggy air near the surface. Assuming the moisture is deep enough, the more humid the air, the lower the thunderstorm's cloud base, more favorable for not only supercells, but tornadic supercells (more on that later).

Forecast for this part of MO is thunderstorms all week.  Beats the shit out of tornados, of course...
