WITH A MOIST AND UNSTABLE AIRMASS OVER THE REGION...THUNDERSTORMS WILL DEVELOP EARLY THIS AFTERNOON OVER THE MOUNTAINS AND PALMER DIVIDE. THESE THUNDERSTORMS WILL MOVE TO THE SOUTHEAST OVER THE PLAINS DURING THE AFTERNOON AND EVENING HOURS. SUFFICIENT VERTICAL WIND SHEAR EXISTS TO ALLOW A FEW OF THESE STORMS TO BECOME SEVERE WITH HAIL 3/4 OF AN INCH OR LARGER AND WIND GUSTS OF 60 MPH OR GREATER. AN UPPER LEVEL DISTURBANCE MOVING INTO THE REGION THIS EVENING MAY HELP CONTINUE THUNDERSTORMS INTO THE LATE EVENING HOURS.
