The cost of cooler weather: A severe storm threat
Posted Jun16, 2008 at 10:52 AM
In order to get some cool air later this week, we've got to get through a threat of severe thunderstorms today and tonight, and a pretty serious one at that. The
Storm Prediction Center has raised a moderate risk of severe weather for most of Virginia north of the Roanoke Valley, with a slight risk elsewhere. The threat today is largely the result of cold air aloft, which will enable warmer and increasingly more moist air to rise into that cold air aloft. This could bubble up some big thunderstorms today, aided by the cold front moving southeast, lifting warm air upward. Strong winds and hail will be the biggest threats; the winds are mostly blowing in the same direction in the different layers of the atmosphere, so tornadoes will probably be few and far between, if any occur at all. Unfortunately, it looks like another day of spotty rain, where one place may get a couple of inches while another not far away gets sprinkles, depending on how the storms develop. The front will push through overnight into Tuesday, and unseasonably cool weather will settle in much of the rest of the week, with higs in the 70s and lows in the 50s, with some 40s, through the weekend.

Other JohnI've been following the storm coming out of WV that's had several severe thunderstorm warnings and now a couple tornado warnings associated with it, particularly because its projected path comes over my house. We can now see the front edge of the outflow coming overhead along with a lot of strong looking mammatus clouds. We're bracing as I just heard a tornado warning went up for Giles...better safe than sorry.

Other JohnThankfully that storm fizzled out as it crossed into Pulaski County, but we did get some gusty winds and heavy rain with the line of storms that followed...although nothing severe thankfully.
