PM Update: Rain threat continues, details messy

By Ian Livingston

Sun and rapidly warming temperatures Wed. and beyond

After the overnight and early-morning rain, much of the day has just been cloudy with occasional drizzle. We're now watching a low pressure develop off the coast, but indications are that its impact on the immediate area will be fairly minor as the heaviest rain stays to the east and northeast. We still have a while to go before conditions trend nicer -- though when they do, it will be very nice!

Radar: Latest D.C. area radar loop shows movement of precipitation over past two hours. Powered by HAMweather. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

Through Tonight: We'll stick with cloudy conditions and occasional drizzle or light rain into evening. Light rain may become more widespread overnight, especially east of the area. Most spots will only see a few hundredths of an inch, with eastern sections perhaps getting into the .1"+ range. Lows should settle to the low-and-mid 40s. Winds pick up from the north, gusting to 30 mph by morning.

Tomorrow (Tuesday): It now appears our best shot for rain from the coastal low comes tomorrow as it backs into land to our north. However, I'm dubious of getting too much on the back side of the system. Nevertheless, rain tries to move in from the northeast during the morning into afternoon. If it does, another general .25"+ (highest totals north and east of D.C.) is possible. If not, maybe just some lighter showers. Highs rise to within a few degrees of 50 as winds from the north gust past 30 mph. Any rain winds down heading into evening, but some sprinkles or showers may persist into the night.

Wettest March ever? Not here, but in places to the north it may very well be the case. The developing coastal storm that is expected to graze the area will likely hit places to the north quite hard with several inches of rain. Many spots, like Boston and New York City, are expected to finish this month as the rainiest on record. Ongoing flooding is a concern throughout the area.

Hey Weather Gang, I'm all for the snow globe to signal the possibility of snow but can I suggest daffodils or some kind of spring flower for nice days? I'm itching to see spring on the horizon =)

I did read this post with some ideas for those in Bethesda trying to deal with the last (fingers crossed) glum days of winter...

PS I love the weather wall =)

Following this winter and spring, is it safe to assume the DC region is now well out of the precipitation deficit we were in a few years back?
