June 8 Southern Plains Severe Outbreak

[Powerball]

 A pretty broad moderate risk area has been issued for North Texas and Southern Oklahoma, including at least a portion of DFW.

Main threat seems to be damaging straight line winds, wirh pretty strong wording in the SPC outlook of 80-100 MPH winds.

Shear values in/of themselves aren't the most impressive (although still sufficient), but with the NW flow advecting in drier air aloft and strong surface heating expected, downburst potential is unusually high (especially once a cold pool gets established).

Very large hail will be a secondary threat with any supercells early on with the steep mid-level lapse rates

Updated Day 1  Outlook has expanded the Moderate Risk area, as well as the highest hail/tornado probabilities, to include all of DFW.

In fact, latest SPC wording mentions hail up to 5" in diameter...
