Thunderstorms will be increasing in coverage starting today. About one-third of the area is visited by a shower or thunderstorm in the afternoon. High pressure, the fair weather defender, is no longer defending us from thunderstorms like it was on Monday and Tuesday.
The chance of rain increases from 30% today to 40% tomorrow.
There is a Heat Advisory over our area today, so some areas may be hoping for a cooling shower or thunderstorm to swing by as the heat index rises to 105-110 degrees this afternoon. However, due to all the heat energy some storms could be strong to severe.
Wind shear and Saharan dust are stopping tropical weather development at this time.
