Good Morning Everyone,
Here is a brief summary of the webinar held this morning:
A strong upper-level system over the four corners region early Wednesday will move into the southern plains during the day Wednesday into Wednesday night.
Ahead of the System...A well-developed low-level jet is forecast to develop from East TX northeast into the Arklatex Wednesday morning. Showers and a few storms will be possible beginning early Wednesday which may pose a small hail threat initially.
But as surface dewpoints surge into the low 60’s by afternoon, the upper level system gets closer and shear increases, stronger storms will be possible across East and Northeast TX, Southwest AR, Southeast OK and extreme Northwest LA. Storms that develop late Wed afternoon and evening will have the potential to produce isolated tornadoes and damaging winds along with hail.
As the evening Wednesday progresses, a strong cold front will be approaching from the west with a squall line forecast to develop along the front. With the line, damaging winds will be the primary threat in any embedded bows along the line. Isolated tornadoes will also be possible along and just ahead of the main line.
Heavy rain will also be possible beginning early Wed AM through Thursday morning for the entire region. Our current forecast calls for 3 to 5 inches of rain possible across northeast TX, southeast OK and southwest AR. Amounts of 2-3 inches are possible in northwest LA, and deep east Texas. Flash flooding may become a problem in the heavier rain bands since the potential exists for higher rain rates given the increased amount of moisture and lift in the atmosphere.
Attached are 2 graphics depicting both the severe weather threat areas and rainfall potential for the region.
The regular weekly webinar scheduled for Wednesday at 10 AM will provide more details on this event.
