Forecast: Summer Warmth and Showers

Over the past couple of days, we've gotten a taste of the kind of weather many of us would like to bottle up and prescribe all summer: tolerably warm afternoons and comfortably mild evenings. Summer warmth will present itself today, but will likely be compromised by late-day showers and storms. Tomorrow, summer transitions back to spring with partial sunshine and highs approaching a pleasant 70 degrees.

TODAY

Warm, late-afternoon showers/t'storms. Low 80s. Enjoy dry and summery conditions through mid-afternoon. But after that, rain chances increase to 60-70%. Showers and thunderstorms are most likely between 4 and 8 p.m. Rainfall potential is generally between 0.25-0.5"

Overnight, shower activity should taper off after about 10 p.m. behind the passing cold front. Lows will drop down to 53-58.

Confidence: Medium-High

Keep reading for the forecast for Sunday into early next week. Also, be sure to check out NatCast and DC UnitedCast.

TOMORROW

Partly sunny. Near 70. Tomorrow may actually be the better of the two weekend days. We'll have a mix of clouds and sun and refreshing cool breeze from the north at about 10-15 mph. The best part: rain is not likely during the day.

Overnight, though, we cloud over with showers likely after midnight. Lows should drop down to 50-55.


A LOOK AHEAD

Monday may be somewhat volatile. After some early-morning showers, the rain may take a break allowing a bit of sunshine that could destabilize the atmosphere ahead of a strong cold front. If the sun pops out, southerly winds may boost temperatures briefly above 70. By late afternoon showers and thunderstorms may develop, some of which may be intense. Check back for more detail about this storm threat over the next couple of days. Confidence: Low-Medium

On Tuesday, a cool pool of air will settle into the region as the jet stream takes a dip over the eastern U.S. Temperatures will likely struggle to top 60 with considerable cloud cover and a slight chance of a shower. Confidence: Medium

Radar is really starting to fire up, I love a good thunderstorm, as long as nobody gets hurt. Stay safe out there folks.

This weather info web page is very nice. Easy to read. Possibly the most aesthetic site on WashingtonPost.com. (The front page is horrible; what a mess.)
