A stormy Friday for some...

Damage in Gloucester County declared a weak tornado...

A warm front lifting through the area earlier today brought some strong thunderstorms, especially east of Richmond, from King & Queen over to Gloucester County. In Ark (Gloucester County), the National Weather Service determined damage to be associated with an EF0 tornado. The "EF scale" or "Enhanced F" scale is an update to the original F-scale to determine the strength of tornadoes. The winds associated with an EF0 tornado are estimated to be in the range of 65-85 mph. This storm in Gloucester produced damage that included a large tree on a house and roofs blown off horse stables. The tornado path was 3 to 3.5 miles long and 100 yards wide.

While there were some nasty storms in the eastern portion of Virginia, most of us escaped with just a few showers and rumbles of thunder. The warmer air took its time getting here and we didn't break into sunshine until this afternoon. That kept the air from becoming too unstable, therefore reducing the severe weather threat.

The weekend...

The upcoming weekend looks mainly dry and pleasant. The only fly in the ointment is an upper level trough that will swing through the Mid-Atlantic later Saturday afternoon and evening. This could trigger a few passing showers and possibly even a rumble of thunder. Otherwise, we should enjoy plenty of sunshine both weekend days, with afternoon temperatures well into the 70s.

Heating up early next week...

We'll then undergo another significant warm-up early next week, with readings in the lower 80s on Monday and approaching 90 degrees on Tuesday. Then another cold front will approach from the north, and this could trigger a round of thunderstorms on Wednesday. Following that frontal passage, temperatures should average in the seasonable 70s to end the new work week.
