A "Particularly Dangerous Situation" (PDS) tornado watch has been issued for central and southern Arkansas for this afternoon and evening, for the expectation of strong, long-track tornadoes in the vicinity of a diffuse warm front draped across the area.  We're currently stationed just south of Little Rock waiting for the storms to our west to intensify and ride the front east-southeast-ward.  Three live streaming teams are in this area, so stay tuned to the tracker for live streaming tornado video!

An outbreak of tornadoes is possible today from Eastern OK/Northeast TX eastward through the Lower Mississippi River Valley.  Wind shear will be most favorable for strong tornadoes along an E-W warm front forecast to move northward across AR/MS through the day.  Due westerly upper flow will allow for storms to move eastward parallel to the boundary, increasing further the chance for long-track tornadoes.  CAPE values will be significant, contributing to the formation of massive hail stones.   The warm front can be seen clearly on the WRF forecast CAPE for 00z this evening - forecast to be along I-40 at this time.  The strong trough responsible for this severe weather episode can be seen in the WRF forecast 500 mb map for 00z (see below):
 
We're currently driving toward an initial target of Little Rock, AR, and will reposition from there depending on the location of the warm front.  Stay tuned to the live tracker as at least 2 streaming teams will be chasing today!
