Weather from NBC Storm Team 4 — Updated at 5 p.m., May 30, 2015 

Heat and humidity continue Sunday with some scattered storm chances later in the day

For this evening most areas will remain dry with some rain in parts of Frederick and Loudoun Counties. Areas west of I-81 will have scattered showers and thundershowers winding down by midnight at the latest. Otherwise tonight will be mild and muggy with just a few clouds around.  Areas of fog will develop overnight mainly in spots that saw rain today. Expect lows in the low 70s in Washington and 60s in suburbs.

So far this is the second warmest May on record, and the heat and humidity continue tomorrow. In fact, tomorrow is now looking to be very similar to today with scattered PM showers and storms possible mainly west of the DC Metro with most likely remaining dry. Storm chances increase Sunday night into Monday as a cold front crawls eastward toward the area. Any storms may contain very heavy rainfall Sunday night and at times on Monday. It looks like the front will be stubborn and linger nearby Tuesday, keeping the risk of showers in the forecast along with considerable cloud cover. Heat and humidity break on Wednesday with highs in the upper 70s. Right now the forecast is dry; however, the computer models are in poor agreement so stay tuned for updates as more information becomes available.

Have a safe weekend.
