Stormy Afternoon
July 29th, 2009 at 12:26 pm by Jeremy Wheeler under Weather
Could be an interesting day with some strong/severe thunderstorms expected this afternoon. SPC has us under a slight risk for severe weather. We have a lot of moisture in place at the surface. Dewpoints are in the mid 70s in some areas. Temps are in the mid-upper 80s right now. There are a few heavy showers just south of the viewing area which are just starting to grow. They are moving up from the south. According to the RUC model, CAPE’s are up to 3500. Lifted indices are -5 to -7. It’s pretty unstable. We’ll have to see what the cloud deck coming in from central Virginia does. This is a quick blog. I’ll try to update later today.

WHAT DOES SPC MEAN
The SPC is the storm prediction center… http://www.spc.noaa.gov
RUC (Rapid update cycle) is a weather computer model which outputs parameters such as CAPE/Lifed Index, which measures how unstable the atmosphere is. Instability is needed for severe weather, including wind shear and a “trigger” to provide some lift.
What happened to the tab that you used to have that showed all of the lightning strikes in the area? I can’t find it. Would you please answer me soon I am working at a resort on the ocean front and have a public pool I may need to close if weather gets worse. Thanks so much you guys are the best
