A few changes for Southwest/Southside Virginia weather from yesterday's thinking:
(1) Severe thunderstorm watch has been issued until noon on this Thursday for much of the western half of Virginia. A line of storms originating from the Ohio Valley has kept momentum overnight. It is expected to weaken crossing the mountains but may still have enough gusto for some stronger gusts in spots.
(2) Afternoon/evening thunderstorms, some strong to severe, still expected to develop. May be hampered in some areas somewhat by whatever clouds/cooling morning squall line leaves behind, but temperatures expected to recover enough for afternoon instability.
(3) Tropical system that briefly became Tropical Storm Arthur near the Texas Gulf Coast may inject just enough moisture northward overnight/early Friday for fairly widespread rain showers with passing cold front. Speed of passing system will preclude large soaking rain but perhaps some locations getting 1/2-3/4 inch type rain, better chances of that to the south of Roanoke than to the north.
(4) Still a dry warm to hot weekend (80s-lower 90s highs) before another chance of showers and storms early next week.
