2008's Warmest Temperatures Bring Renewed Severe Threat Tuesday

Temperatures are expected to flirt with 80° areawide on Tuesday. Should that happen, it would be the first such occurrence of 2008, but would also bring a slightly elevated chance for severe thunderstorms come Tuesday night with the approach and arrival of another cold front.

Below you'll see the official outlook from the National Weather Service's Storm Prediction Center, placing us on the Eastern fringe of the slight risk area for severe weather.

There are a few things working to our advantage in this particular scenario. First, the frontal passage in the overnight hours makes things just a bit tougher for severe storms to get going here. Secondly, and perhaps more importantly, moisture appears to be a bit more limited than in past situations we've seen here. Remember back to Friday, when storms did move through the area, but remained just below severe criteria. Dew points, a measure of moisture in our atmosphere, were only in the mid to upper 50s on Friday. Dew points Tuesday are to peak in the upper 40s to low/mid 50s.

As a rule of thumb, we'd like to see dew points at least in the 60s to promote any widespread severe weather threat. So with that in mind, right now, I'm not all that convinced that severe weather is a significant threat to us. However, it still does bear watching, and we'll keep a very close eye on this as we move forward.
