Thunderbolt and lightning, very very frightning

The National Weather Service just posted a Severe Thunderstorm Watch (number 502, although I'm getting 404 errors on the associated page) for my neck of the woods, from now until eight PM tonight. Nothing happening at the moment directly overhead, but I'm between suspicious radar lines both to the southeast and the northwest.

We're now on six days in a row of high temperatures at or over ninety degrees. If we get some sunshine later this afternoon, we may well get a seventh. OTOH, there's a big cool front coming through which will knock down temperatures - and, more importantly, dewpoints - later this evening and overnight.
