July 23rd Severe Weather Potential

723

CAPE 1000-2000

LI –2 to –4

Lapse rates 5.5-6.5

Shear 30-40 knots

Trigger: Warm front

Temperatures in the 90s

Dew points in the 60s and 70s

A warm front will be moving northward across the region today and this may act as a trigger to spark off some severe thunderstorms.

I am a little wary though on the severe chances today due to the fact that radar shows rain moving across the region now..

This may cause clouds to linger longer across the area and too much subsidence left behind with a more stable atmosphere. Also currently there is decent cloud cover in place..

So while issuing this outlook, keep in mind the possibility that these things could hinder severe weather. I think the main severe weather effect would be strong wind damage .
