By Thursday morning we’ll be placed in the warm sector of a low pressure system  to the north of the region. This means conditions should continue to warm and precipitation should be less abundant. Afternoon highs will reach the low 70s most likely.

By Thursday evening and early overnight, there’s a strong precipitation signal from the models, meaning some thunderstorms may be possible. A southward moving cold front will drive showers and thunderstorms into the region. The severe weather threat is very low as of now, but not zero. Some locally gusty winds may be possible if stronger storms can develop.

Showers will continue overnight. There remains some question about when the cold front will move through. As of now, we’re going to remain conservative on low temperatures and go with lows in the low to mid 60s. Rain totals through Thursday will be between 0.5 – 1″.
