Discussion

A surface cool front is pushing off the coast this morning and its passage has cleansed the atmosphere of the high heat and humidity from yesterday and it’ll lead to improving conditions all along the I-95 corridor. Clouds will give way to sun and overall humidity levels will come down today with the onset of a northwesterly flow of air in the lower levels of the atmosphere. It’ll stay rather comfortable through tomorrow and then the humidity builds up again late Friday night and Saturday ahead of the next cool frontal system. That front can cause another round of showers and thunderstorms in the Mid-Atlantic region this weekend and it’s passage will be followed by another comfortable air mass for the early part of next week.
