I heard a couple of comments a lot this weekend and today... "That was the hottest I can remember feeling since I've been in the Carolinas" and "I've never seen so much lightning as I saw Sunday night". Well, the first comment has been confirmed by the numbers! Sunday was the hottest day on record at GSP with a high of 107! And last night we saw some extremely frequent and prolific lightning thanks to the high heat from Sunday. Personally, it's the most lightning I've ever seen at night. It was truly unreal.
So, with the unprecedented heat came some unprecedented storms! When the atmosphere finally became supportive of storms on Sunday(or when the cap broke as you might have heard it mentioned before), there was a tremendous amount of hot air at the surface just ready to explode into the sky. The fast rising, extremely hot air causes storms to develop at a rapid pace, which lead to rapid lightning production. Once the storms got going, they sustained themselves well into the night with all of that instability and leftover outflow boundaries.
Luckily we didn't see much storm activity (so far) today, and we've stayed a good bit cooler thanks to the clouds. Tomorrow I expect more sunshine and higher temps once again. Each afternoon through July 4th we'll have a threat for scattered t-storms. And any storm that forms will be capable of damaging wind, hail, and especially lightning.
As for the historic heat... well the temps will still be very hot, but not at the levels we had this weekend. Tomorrow I'm going 97 for the Upstate, and we'll generally stay in the mid to upper 90s for highs through the week and upcoming weekend.
Thanks to all of you who sent in your storm and heat pics!
