Severe Outlook March 18th 2012


This is our day 2 outlook for Sunday...

Severe Parameters
CAPE looks to be 500-2500 depending where you are located
LI is 0 to - 8 again depending where you are located
Mid Level Lapse Rates 7.0-8.0 depending on location

At the surface low pressure will be moving across Wyoming with associated trough which should take a negative tilt. A cold front will be stretched from north to south..
Initially we think that the region will be relatively capped but storms should develop along the dry line which should be located N to south ..almost along the TX/NM border but slightly east of that border... Its near this dry line that should have the greatest risk of severe weather.
Initially as we stated we think that things will be kind of scattered and moisture return may be an issue as well...
Greatest threats appear to be Large Hail and Winds...

In the evening ..which is when the trough should begin to take on a more negative tilt ..it is at this time that coverage should become more wide spread. This whole system will advance slowly east wards so that monday ..the severe threat will shift further to the east...
