Stormy weekend with an eye on Isaias
Afternoon storms this weekend. Isaias could bring impacts late Sunday.
The soupy air has led to a daily chance of storms lately. This weather pattern will only be further bolstered by a surge in tropical moisture ahead of Isaias this weekend, especially late Sunday afternoon. We’ll see afternoon storms both day. Isaias’ effect on our weather will really get going Sunday as we begin a multi-day stretch of tropical downpours with some flooding possible.
A possible tornado was confirmed Saturday evening around 7 PM near Fincastle. A number of viewers sent in pictures and video of the funnel/tornado as it tracked to the northeast in Botetourt County. So far there have thankfully been no reports of damage.
A lingering storm late, otherwise partly cloudy skies. Overnight will be familiar with muggy lows in the upper 60s to low 70s and some patchy fog.
A cold front associated with the same system that brings storms on Saturday will help generate more afternoon storms on Sunday afternoon. In addition, there will likely be an ideal set-up for what is called a Predecessor Rainfall Event (PRE) as tropical moisture moves into our area ahead of the storm and triggers storms. With the help of the front and lift created by the Blue Ridge Mountains, we could see an increased risk of flooding beginning in the afternoon and carrying into the night. Highs climb back into the 80s and 90s.
Hurricane Isaias (ees-ah-EE-ahs) continues to threaten the East Coast. The latest forecast from the National Hurricane Center has it as a Category One storm as it heads towards the United States. The track has shifted a little to the west and the latest models have indicated higher potential of a inward track into the Coastal Carolinas. This path would likely lead to widespread storms across our area late Sunday through Tuesday.
