June 13th Severe Weather Potential

613

The above outlook is based on a blend of the latest NAM/SREF.

CAPE is anywhere from 500-4000 depending on where you are located..

Lift Index is anywhere from 0 to –8

SWEAT index is 400 or above in NW ARK into Central & Western Missouri to SW Iowa and back thru Nebraska and Ks. Also the eastern half of South Dakota.

EHI is at 2.5-3 from NE KS to western Missouri from North to south along the western Half. . It is these areas in combination with the SWEAT at 400 or above that have the greatest potential for any tornados.

Weather Synopsis

Low pressure will be located over SE Colorado by 2 AM . Extending from this area of low pressure is a warm front to the east then turns into a cold front which is connected to another low pressure over or just off the coast of NJ. Showers and thunderstorms will stretch from north to south in association with the low pressure over SE Colorado. During the day this low pressure will start to move eastward and that will push the warm front slowly to the north ..while the cold front will have cleared the east coast bringing sunny and pleasant weather to the region from Pa south until you get to the other small severe zone which will be associated with a weak area of low pressure that develops along the southern part of the cold front over south carolina along the coast.

Aside from the areas mentioned above with the potential for a tornado the main threat will be winds in excess of 60 MPH and large hail.
