Based off mesonet and ASOS data, there appears to be a surface boundary running right along I-97 in Anne Arundel County. Might see something fire up or get enhanced by that later on.
Prince Anne mesonet site running a heat index of 117°...looks like we lost a degree or two on the dewpoints but that's allowing air temps to get higher?
Agreed. I was very skeptical of the Euro and GFS going for three days in the 100s. We've seen that fantasy mid range heat vanish before. Not this time!
