Scattered storms over the weekend

Weather

Scattered storms off and on Saturday and Sunday

The stagnant pattern of rainy weather will continue through the weekend with the intensity of the rain still an issue.  The past few days we have been dealing with the off and on rain showers that increase in the afternoon heat and energy.  There have been pockets of heavy rain, gusty winds and on Thursday we added large hail to the equation.  Several reports of hail over an inch in diameter and even a couple reports of hail the size of an egg in the Cave Spring region of Roanoke.  Needless to say, the storms were very intense to generate that large of a hailstone.  Then there was the rain.  The storms Thursday were not very organized in direction but rather merged or developed from outflows or gust fronts and basically fed off of themselves.  It was a very active day. 

As for the weekend I don’t expect to see much more of that, but I do expect to continue to see the storms ignite in the heat of the day.  Friday will see it’s fair share of storms again, but the cloud cover reduced the potential energy from the sun leading to a bit less activity.  The rainfall from Thursday has pushed certain areas, especially the Piedmont, to the brink of saturation.  Any rain Friday and Friday night may lead to localized flooding.

The stalled front that was the blocking mechanism that collected the storms in the commonwealth as moisture fed in from the south and west is now in North Carolina.  This will limit the feeding frenzy of the storms, but we still have storms to contend with today and over the weekend.  Still aggressive storms, but may not be as widespread as Thursday. 

Saturday and Sunday will be looking at scattered showers and storms.  A bit more sunshine than rain is on the docket for Saturday and Sunday.  Originally, the thought process has the tropical disturbance off the coast of Florida will move up the coast and give us a good deal of rain over the weekend.  That thought has changed since the front has now moved through the Commonwealth.  The stationary front will be positioned along the coast so the moisture from the tropical Atlantic will be effectively blocked.  There will be a few waves of energy or low-pressure cells that will ride along the front, and they should draw back some moisture to the Commonwealth each day.  Expect temperatures to be near normal and scattered storms each afternoon.  More or less a typical early August weekend.

As for the rest of the week, Monday looks to be the best chance for widespread rain to return.  Flooding will be an issue at that point since the region is pretty much at the tipping point so any more rain will push us to the flooding point.  We dry out a bit on Tuesday and Wednesday before another round of rain arrives on Thursday.

Stay safe.
