Finally! Something other than the heat to talk about. Wait... we're still talking about heat, too. Yesterday's high of 100° was the third of the season, and also prompted our 7th (and subsequently 8th) Heat Advisory of the season. All of that heat is being met by a sagging cold front this afternoon to prompt our 6th Severe Thunderstorm Watch of the season:
We're in an area of very hot, moist air, with temps in the mid 90's and dewpoints hanging at or a little above 70°. That alone wouldn't be much for afternoon storms, but a cold front in the northern-most part of the state is enough of an area of convergance for storms to pop this afternoon.
It was apparent early this morning that we may have a decently active day as small showers were able to develop in the area before sunrise. The radar hasn't been empty since then.
What to Expect
We could see very heavy rains, a little hail, and the potential for gusty downbursts with all of these storms. Individual cells aren't expected to move very fast, which will increase rainfall amounts and lessen the chance for major wind producing storms.
We need the rain. This is a good thing.
While we would ideally like a large, slow moving system to give us a long soaker, we don't see those much in the middle of the summer... so this is as good as we'll get for a while.
PWAT's are around 1.7, which is good enough. Much higher and we run the risk for flash flooding, so with those kinds of numbers we know the atmosphere is saturated enough to dump a good amount of liquid with each of these storms.
Supercells are unlikely this afternoon. Instead we should see individual cells develop and congeal in to larger storms.
It'll be nice to see some rain.
