A few summer-like days are going to string together to start this week. Look for warm days, along with some of the first noticeably higher humidity levels, and slight chances of a few isolated afternoon/evening thunderstorms. A weak front is draped across the Washington region, and with such warm temperatures and higher humidity levels, any weak little system will spark the possibility for a storm in the afternoon and evening hours. Morning low temperatures will start off mild each day through Thursday with lows only in the 60s. The next cold front sweeps through on Thursday with a high likelihood of showers and thunderstorms. Cooler spring air will drape across the region on Friday and into this next weekend!
