Early spring snow around Washington, D.C. (PHOTOS)

This morning's brief period of snow behaved as forecast for the most part, with just some conversational flakes inside the beltway that coated car tops, and light accumulations of an inch or so to the west and southwest.

Chance of snow/mix for Monday morning commute; most likely impact west of D.C. Beltway

Cold air has seeped into the region today setting the stage for some messy weather late tonight into Monday morning as a wave of low pressure approaches. West and northwest of the beltway, a light accumulation of snow (one to perhaps two inches) is possible. Little accumulation is expected inside the beltway and to the east and southeast where more of a mix of precipitation is favored

Cherry blossom peak bloom forecast from Capital Weather Gang: April 5

What a difference a year makes. Last year’s record-warm March led to a tie for the third earliest cherry blossom peak on record on March 20. This year, cooler than average weather is likely to push the peak bloom back considerably. We project blossoms will peak between April 3 and April 7, or around April 5.

Maryland, Virginia winters turn less snowy as New York, Boston enjoy snow bonanza

The northern end of the Northeast megalopolis lies in the proverbial sweet spot for snow, as general observations have shown over the years. A closer examination of the historical record reveals not only increases in the seasonal snowfall totals for Boston and New York City, but also unearths this all too predictable truth: Maryland and Virginia winters are becoming less snowy.

How global warming spoiled the Snowquester

Just a few degrees was the difference between bare ground and a winter wonderland in D.C.’s urban core last week. Would the storm, which was a disappointment to so many Washingtonian snow lovers, have played out differently had it occurred 100 years ago? Historical data say yes.

The blizzard of 1993: 20-year anniversary of March Superstorm

Twenty years ago today, among the most intense cold season storms of the 20th century began to organize. The storm - which would dump crippling amounts of snow from Florida to Maine - resulted in over 300 fatalities and $9 billion in damages (2012 dollars). Known as the “Superstorm of 1993”, “The Blizzard of ‘93” and “Storm of the Century”, it is ranked as an “extreme” category 5 storm on NOAA’s Regional Snowfall Index (RSI) scale.

Of the meteorological winter months (December-February), February was our coldest, but only slightly below normal (-0.7F). The month was also drier-than-normal, with a deficit of 0.95 inches. But it sure seemed like a wetter month than that.

snow was finally coming, this was not a mirage.

In the immediate Washington, D.C. metro area and points east, the snow output of has underperformed. We conceded late this morning that our forecast of 5-10 inches in this area would probably not be achieved, but indicated a few inches remain possible - let’s say 1-4 inches.

Could a quiet sun cancel global warming?

The current solar maximum, the high point in the sun’s activity over an 11-year cycle, is the lowest in over 100 years NASA says. Scientists speculate solar activity may decline further in the coming decades. Could a quieting sun cause the climate to cool enough to stall or even reverse global warming from the build-up of greenhouse gases? Leading climate scientists say no, the effect of the sun is too small.

There’s a very small chance this combination could squeeze out a few rare snowflakes along Florida’s central west coast Sunday morning.

Clouds and flurries stream into Washington D.C. and Baltimore regions from Great Lakes

Readers in Howard and Baltimore counties have spotted snow flurries, and long wave-like cloud streaks have lined up from the lee of the Appalachian mountains to the Chesapeake Bay. These weather features are brought to us - at least in part - from Lake Superior, about 1,000 miles away.

But a very large, meteor or “fireball” stole its thunder, violently blowing up as it entered the atmosphere over central Russia, producing a shockwave that shattered windows, rocked buildings, and injured hundreds.

Confidence continues to grow that Boston will face a major to historic blizzard Friday into Saturday. New York City may also experience a period of blizzard conditions, but questions remain about how much precipitation falls as snow. Washington, D.C. will likely just get grazed by rain and, perhaps, a little wet snow at the onset.
