THERE IS A SLIGHT POSSIBLITY OF SEEING A STRONG OR SEVER THUNDERSTORM THIS MORNING. ONLY TWO POSSIBLE HAZARDS CAN BE FOUND WITH ANY STRONG ACTIVITY...HAIL AND WINDS. A VERY PROGRESSIVE UPPER LEVEL JET WILL ALLOW ANOTHER STRONG SHORT WAVE TROUGH TO MOVE THROUGH BY THE WEEKEND. TIMING IS NOT THE QUESTION BUT THE PLACEMENT IS.
