(Posted Monday 6/15 8am)
Good Monday morning! Another hot, humid day on tap for the Shenandoah Valley with 90+ degrees likely (would be 5th 90 degree day in a row).
A few showers ongoing this morning over the northern valley will diminish over the next several hours. Sunshine will then increase instability this afternoon allowing more scattered popup showers and storms to form...very hit or miss but each capable of producing very heavy rain and gusty winds. An upper level disturbance will bring a bit more widespread chance on Tuesday.
As for invest 91L...although hurricane hunters found tropical storm force winds well north and east of its center yesterday, it remains unnamed due to the disorganization of convection and lack of defined low level circulation. They will be investigating again this morning. Still likely this becomes a weak tropical storm (Bill) before landfall along the Texas coast sometime tomorrow. The heavy flooding rains will be the big story.
