Gloomy, Wet, then Windy Weekend; Flooding Sunday?
Saturday's Cherry Blossom parade could be spared
A. Camden Walker @ 10:00 AM
There's no spinning this for positive press. This weekend will, in general, be mostly undesirable with a chance of miserable (Saturday night through Sunday) thanks to a powerful Nor'easter. Find the duck boots, waterproof scarf, dress in layers -- oh, and any umbrella you try to use later this weekend will prove useless as it is destroyed in the wind.
Brisk but Becoming Sunny. The better news in this weekend forecast, today's sunshine (after morning cloudiness) and strong winds should be embraced. Mid-to-upper 50s will be a struggle, and hardly comfortable in the constant breeze, but you have to believe me that it will be all downhill from here! Tonight, winds will die down but clouds will thicken. Low temperatures dip to about 40 degrees.
Rain Waits for Evening. Under overcast skies for most of the day, temperatures will struggle into the middle 50s. Winds will not blow quite as strongly as Friday, but it will feel nippy all the same. A stray shower near sunset isn't out of the question but the bulk of the storm will hold off until after the Cherry Blossom parade and street festival.
You have to ask? It will rain, heavily, by dawntime. Temperatures in the upper-40s and a raw, wind-driven downpour are perfect for the trek to church. Certainly. The rain may decrease a bit in the afternoon, but winds will strengthen with the prospect of powerful gusts.

That these lines are packed closely together signifies an intense storm with strong winds. The green and yellow shading over Northern Virginia and extending into Pennsylvania depicts heavy rainfall totals.
The National Weather Service Forecast Office in Sterling provided a nice summary of the possible storm impacts in its early morning discussion:
Tomorrow, April 14th, people across America will gather at "meaningful, iconic places to call for action on climate change," according to the National Climate Day of Action Web site. Organizers are hoping folks will "hike, bike, climb, walk, swim, kayak, canoe, or simply sit or stand" with banners that will urge Congress to support an 80% reduction in carbon emissions by 2050.

Storm Impacts
The National Weather Service Forecast Office in Sterling provided a nice summary of the possible storm impacts in its early morning discussion:
THREE THREATS THAT WILL NEED TO BE MONITORED THIS WEEKEND. THE BIGGEST WILL BE WIND...FOLLOWED BY FLOODING...THEN COASTAL FLOODING AND SNOW. STRONGEST WINDS WILL LIKELY BE MONDAY ON THE BACKSIDE OF THE COASTAL. GUSTS OVER 40 MPH...ESP FOR MARYLAND AND NOVA SEEM A GOOD BET AT THIS TIME. FLOOD THREAT PERIOD LOOKS TO BE SATURDAY NIGHT AND SUNDAY. A WIDESPREAD ONE TO TWO INCH RAIN IS EXPECTED. ANY COASTAL FLOODING WOULD BE SATURDAY NIGHT INTO SUNDAY. THERE IS NOT A VERY LONG PERIOD OF E COMPONENT WIND...BUT WITH THE STRENGTH OF THE SYSTEM AND MOON PHASE GETTING NEAR NEW AT THAT POINT...WILL HAVE TO WATCH THE TIDAL LEVELS. AS FOR THE SNOW THREAT...IT IS MIDDLE APRIL WHICH MAKES IT VERY DIFFICULT TO GET MEASURABLE SNOW...BUT THIS DOES SEEM LIKE AN UNCOMMONLY STRONG COASTAL. THOUGHTS AT THIS TIME ARE THAT ANY SNOW WOULD BE SUNDAY AND CONFINED TO THE BLUE RIDGE AND WEST IN VA...E WV...AND WESTERN AND N CENTRAL MD...WITH THE BIGGEST THREAT ABOVE 1500 FEET. FURTHER...ANY SNOW THAT DOES FALL WILL HAVE A VERY HARD TIME STICKING TO PAVEMENT.
