March 1-15: Wintry Start then Moderation

[donsutherland1]

Bob rulz,

I'm happy to see that you received more snow than the City. Hopefully, there will be one more opportunity for meaningful snowfall before the season ends.

The airport is usually the least snowy part of the valley (unless there's lake-effect), and I usually receive more than there, even though I'm still technically in the city.

And thanks don, hopefully I will see more meaningful snow this season (there's only been 3 "decent" storms so far this season). Time is running out though (spring snow just isn't as common as it used to be here...).

Verification:

One of the worst discussions this winter.

∙ The 3/1-7 period will likely see readings in the Mid-Atlantic/New England/eastern Great Lakes region average below normal.

The temperature anomalies during the 3/1-7 period were as follows:
Boston: -5.0°
Detroit: -1.6°
New York City: -4.9°
Philadelphia: -2.6°
Washington, DC (DCA): -2.0°

∙ The 3/8-15 period should see moderating temperatures with readings averaging out near normal in New England and somewhat above normal in Washington, DC and Richmond and possibly as far north as Philadelphia and New York City.

Highlighted by a record warm air mass, readings finished much above normal readings. The temperature anomalies for this period came as follows:

Boston: +6.3°
Detroit: +10.4°
New York City: +9.0°
Philadelphia: +11.5°
Richmond: +14.9°
Washington, DC (DCA): +12.5°

∙ Accumulating snow is likely during the 3/1-10 period in Boston, Detroit, New York City, and Philadelphia, and Washington, DC. One or more of these cities could pick up 4” or more, with odds favoring the Philadelphia to Boston region.

Total snowfall for the 3/1-10 period was:

Boston: Trace
Detroit: 0.4”
New York City: 1.3”
Philadelphia: Trace
Washington, DC (DCA): Trace

∙ The 3/3-8 period could feature a significant storm for parts of the East Coast.

A storm impacted parts of the East Coast on March 2. Most amounts were fairly light. New York City picked up 0.52”. But that was among the heavier amounts.

∙ With the block having faded, the storm track shift to a Great Lakes trajectory near mid-month (probably in the 3/10-15 timeframe). During this timeframe, readings could surpass 60° on at least one day in Washington, DC and Richmond and perhaps 50° in Detroit.

The March 10-15 period feature much above normal readings, along with some record warmth. Highest temperatures were:

Boston: 66°, March 10
Detroit: 69°, March 13
New York City: 74°, March 10
Philadelphia: 79°, March 13
Washington, DC (DCA): 85°, March 13
