Storm chances next week

Just an early heads of up for what could be a stormy middle part of next week.  So, I'll just go map by map here and show some of the stormy ingredients we have for next Wednesday and Thursday. 

The first map below is the CAPE (Convective Available Potential Energy) map.  This basically shows us how much fuel we have for strong storms.  CAPE values over 1,000 here in blue indicate that if storms do form, they could be strong.

The next map is showing the mid-upper level energy.  This is a strong VORT Max (Vorticity Maximum), which produces strong upward momentum.  This will help kick up storms over the Midwest and South. 

The next map is also at the 500 mph level (around 18,000 feet agl) and is showing the strong winds aloft.  These strong winds can due a few things.  Keep storms strong for longer, help produce strong and potentially damaging wind gusts at the surface, and can be another "kicker" to get storms going.  The strength and orientation of the strong winds aloft can also play a part in producing rotating storms, and as with any storm threat, we have to watch for tornado potential.

The last map shows all of the rain which could be produced by the showers and storms next Wednesday or Thursday, or both days.  This map is early Thursday. 

This is still 6-8 days away, so the timing, intensity, and location of this storm system could change.  We'll keep an eye on it!
