CENTRAL, WESTERN AND WEST-CENTRAL OKLAHOMA, AND ADJACENT NORTH TEXAS.
MARGINAL MID-LEVEL LAPSE RATES SHOULD LIMIT HAIL SIZE TO AROUND QUARTER-
SIZED. HIGHER DOWNDRAFT CAPE (UP TO 1500 J/KG OR SO) ACROSS SOUTHWEST
OKLAHOMA AND WESTERN NORTH TEXAS WILL LEAD TO A FAVORABLE ENVIRONMENT
FOR SEVERE WIND GUSTS UP TO 70 MPH. AS HAS BEEN THE CASE THIS PAST WEEK,
HIGH PWAT VALUES WILL CONTINUE TO BE PRESENT WHICH COULD RESULT IN
EFFICIENT RAINFALL, AS WELL. FLASH FLOOD POTENTIAL SHOULD BE
LIMITED MAINLY TO NORTH-CENTRAL OKLAHOMA FROM A LINE NEAR AND WEST
