Fewer storms today translated to hotter afternoon temperatures with highs in the low-mid 90s area-wide. Heat indices reached into the lower 100s and I would expect more the same tomorrow. We should see a better chance scattered showers and storms tomorrow afternoon. Higher rain chances will be likely Wednesday and perhaps Thursday in response to a weakening and stalling frontal boundary. Although I wouldn’t be looking for a cool down, slightly drier and more stable air should arrive from the northeast for Friday into the weekend with highs pushing back into the low-mid 90s this weekend. Rain chances will still be in the forecast but they should be in the slight category Friday through Sunday.
As I alluded to last week, tropical waves in the Atlantic are beginning to look more like tropical waves should this time of year. There will probably be some development over the next few days with one or two systems. One disturbance is about 850 miles east of the southern Windward Islands while the other is closer to the African coast. The NHC began running model runs on the wave east of the Windward Islands which means they are anticipating some development too. Visible satellite imagery this afternoon revealed a good signal for at least mid-level cyclonic turning so in the next day or so we may be talking about a depression. The other wave near Africa already has surface low pressure attached to it so if the system can survive some dust to the north, it too will have a chance for development later this week.
