Severe Threat Still In The Cards

An Upper Level Low and strengthening jet stream overhead will bring widespread showers and t'storms to the Southern Plains over the next 24 hours. This afternoon and through the evening some severe weather is possible across the Texas Panhandle into far western north Texas and western Oklahoma. Hail up to golf balls and gusty winds up to 65 mph will be possible. The tornado threat does look very low but could rule out a couple tornadoes warning for a quick spin up.

On Friday the upper level low continues to pivot and lift northeast as a strong mid level jet streaks across Texas and Oklahoma. This will allow for moderate shear to take shape not only at mid levels but down at the ground creating some large hodos. The key to the severe weather setup tomorrow will be timing and instability. If parts of western Oklahoma to can warm and break into some sunshine with CAPE climbing over 1,500 joules. Then the severe weather threat looks to be there with large hail and some tornadoes in the individual storms. Currently SPC, like expected posted a slight risk yesterday and has expanded it today for a slightly greater threat. They as well have questions on the amount of heating and how much stable air will be left from the morning rain. Unfortunately its not letting me post any maps or outlooks but you can see them here at http://www.spc.noaa.gov/

My co-worker meteorologist Austin Bowling and I plan on being out in the field by early afternoon tomorrow. So plan on another update tomorrow morning and hopefully watching us on our live streaming dashcam tomorrow afternoon.  Have a great Thursday evening!
