 before midnight tonight. Then tomorrow, it's a cool, dry north wind. Temperatures in the low 80s, a great way to start July. And temperatures tomorrow night will be back to the 60s with upper 50s outside of the Beltway. It turns hot and humid once again. The 4th of July already looking at 95, but the heat index around 100 for the upcoming holiday. 79, Silver Spring. It's 82 in southeast and 78 in Fairfax.
