Forecast: Pleasant Weather Just Passing Through

By Dan Stillman

Shower chances return late Thursday into weekend

* Re-framing Emissions Goals | Later: Sunny Mother's Day Photos *


Today: Mostly sunny a.m. Partly cloudy p.m. 68-73. | Tonight: Partly cloudy. Isolated shower? 50s. | Tomorrow: Sun & clouds. Stray shower? 40% chance late-day showers/t-storms. | A Look Ahead


Today we're treated to a second nice day in a row. You'll probably need a jacket through much of the day, especially this morning, but all in all the weather should be good enough to walk that extra block to your favorite lunch spot, or maybe take in an outdoor screening of Spider-Man 2. (Related note: Did you hear that Screen on the Green may not happen this summer?) So get out and enjoy the outdoors -- before rain chances return late tomorrow and into the weekend.

Today (Wednesday): Crisp early-morning lows in the 40s and upper 30s rise to afternoon highs in the upper 60s to low 70s, while skies go from mostly sunny in the morning to partly cloudy in the afternoon. Winds will be light from the south/southeast (around 5-10 mph) and humidity will be low. Confidence: High

Tonight: Skies stay partly cloudy as evening temperatures fall through the 60s to overnight lows in the 50s. An isolated shower or two can't be ruled out, well in advance of a cold front approaching from the Midwest. Confidence: Medium-High

Does the nice weather hold? Keep reading for the forecast through the weekend....

Tomorrow (Thursday): You'll feel the humidity increasing during the day thanks to a consistent breeze (10-20 mph) from the south. Highs should top out near 75-80 under a mix of sun and clouds. Other than an isolated passing shower, rain should hold off until the approaching cold front brings a 40% chance of scattered showers and thunderstorms by late afternoon, or maybe not until during the evening. Confidence: Medium

Tomorrow Night: A 40% chance of showers or thunderstorms lasts through the night, with partly to mostly cloudy skies and lows in the low-to-mid 60s. Confidence: Medium


Thursday's cold front looks like it will stall out close enough to the area to keep us partly cloudy on Friday with the chance of some showers and an afternoon thunderstorm. Temperatures should be comfortable with highs in the 70s. An occasional shower stays in the forecast for Friday night with lows in the upper 50s to low 60s. Confidence: Low-Medium

The weekend forecast is still taking shape. Neither day looks like a washout, but both days will probably have at least a chance of showers and thunderstorms, with highs in the 70s to near 80 on Saturday and 60s to near 70 on Sunday. Confidence: Low

This looks like the forecast for Bike-to-Work day (Friday) isn't too bad. Maybe a shower, but not enough to keep folks from riding. I'm hoping to see lots more folks on bikes then.

How's it looking for Ocean City?

I'm thinking it's time for consistently warm and sunny weather. Enough of this 30's/40's in the morning with a cool breeze during the day or kind of warm but with rain. Ugh.

Aw, man... and I was looking forward to Screen on the Green too... :(

When we discuss this front stalling out for the weekend, just how bad are we talking about? Low ceilings, low visability and rain? Trying to plan a flight from Leesburg to Boston and back. Not liking how things are shaping up.

Chris_ .. as it stands now, this will not highly impact flights this weekend.

Forecast for Ocean City is similar to here. Chance of showers and storms both days, but better chance on Sunday. It won't be a washout -- knowing the timing of showers/storms at this point isn't possible.

Per Camden's comment, we're not talking low clouds and visibility all weekend. A chance of showers and t'storms both days -- but with some sunshine as well...particularly Saturday.

The current waves of storms are fizzling out in Indiana/Ohio before they reach the mountains. High cirrus is advancing from the west. Current evidence for cirrocumulus is minimal and that chiefly in contrails. Present indication is that unstable air over the Midwest is stabilizing as it moves east; upper air soundings for Dulles at 1200Z show minimal convective risk.
