The surface wind pattern seems to be variable from NW to NE tonight according to MOS guidance runs, which makes predicting the low a little difficult. Any deviation of wind direction could alter the temp by a couple degrees due to any local advection. Moisture levels will increase as guidance suggests dewpoints in the 60s. I will call for clear skies tonight with a low near 65. For Thursday, expect fair skies with a high near 90.

It's going to be the same song-and-dance for Thursday as high pressure at the surface and aloft will continue to hold over the region. This will allow warm temps and mostly clear skies to remain over the area.
