Thunder Threat Not Just Tonight...Also Tomorrow As Well

Tonight's scattered thunderstorms are associated to a disturbance that is tracking northeast. Those storms will continue into Thursday as storms will be scattered in nature through the course of tomorrow.  The best chances appear to be early in the day as the disturbance pushes into the area, followed by a second shot of thunder in the afternoon hours as daytime heating agitates the atmosphere and may trigger more thunderstorm activity.  Modeling is not consistent on the afternoon threat, however, with the GFS showing a higher percentage of the area getting scattered storms and NAM being less aggressive in the threat.  In the GFS' case, the storm threat is scattered -- not widespread.

This will result in today likely being the best chance of us hitting 90 degrees this week thanks to additional clouds being around to knock temperatures back a notch or two.


While thunderstorms tonight and tomorrow likely will not be severe, there is a chance of locally heavy rainfall in some of the storms as PWAT's push above 1.75" later tonight and stay over 1.50" through the day Thursday.  I don't foresee any flooding but some heavier rumbles of thunder are in the offing for a few parts of the region.

We'll keep you updated on this through Facebook and twitter as needed!
