Weather from NBC Storm Team 4 — Updated at 12 p.m., May 30, 2015 

Summer-like weather this weekend as a southerly flow of warm and humid air continues!

On the last weekend of May, it will feel more like late June or July with plenty of heat and humidity on tap. With a mix of hazy sunshine and clouds, temperatures will soar into 90 degrees Saturday afternoon. There is only the slightest chance of a thunderstorm but that would be mainly for the higher elevations in the northern and western part of the WTOP listening area. Tonight will be mild and muggy under a partly cloudy sky with patchy fog possible and lows near 70 in DC with 60s in suburbs. Sunday will bring more of the same — a partly sunny sky and mostly rain-free during the daylight hours with temperatures sizzling into the upper 80s. As a cold front slowly approaches late in the day, it’s possible we see a few thunderstorms develop late in the afternoon and evening, especially north and west of town and closest to the cold front. We expect chances of storms to increase Sunday night into Monday as the front crawls eastward. Any storms may contain very heavy rainfall. 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. The good news is that cooler temperatures will return with highs only in the 70s for Tuesday and Wednesday.

 

Have a safe weekend.
