High pressure means that, barring a few clouds and temperatures in the mid-30s, this afternoon feels like a good day. But as we head to tonight, expect temperatures to drop into the mid- to high-20s, but fortunately, light winds will mean that it will not feel too cold. A buildup in clouds, however, will mean that tonight feels dull. Just bundle up with a light or medium jacket and enjoy the sunshine while you still can.
For perspective on how cool it feels, the average high for this time of the year is around 42, with a low in the mid-20s, so it is slightly cooler than normal.
