Full Worm Moon
Thanks to Aaron Weidner for the image below, who snapped this from Bluefin Bay on Saturday night as the Full Worm Moon was rising over Lake Superior! Nice picture!!
According to Space.com, the full worm moon gets it’s name from:

“Mar. 16, 1:08 p.m. EDT: Full Worm Moon —In this month the ground softens and the earthworm casts reappear, inviting the return of the robins. The more northern tribes knew this as the Full Crow Moon, when the cawing of crows signals the end of winter , or the Full Crust Moon because the snow cover becomes crusted from thawing by day and freezing at night. TheFull Sap Moon, marking the time of tapping maple trees, is another variation.





 Today’s Forecast: Weather

I found this gem on the Anchorman Facebook page… Enjoy!



Weather Outlook
2 fairly large areas of low pressure will be impacting parts of the country through the early/middle part of the week. The first of which will be situated across the Eastern Seaboard on Monday with heavy snow still ongoing across parts of the Mid-Atlantic Region. The second storm will be starting to take shape across the Upper Midwest/High Plains. By Tuesday, that northern storm will have bigger impacts on the Upper Mississippi Valley by Tuesday.



Precipitation Forecast
According to NOAA’s HPC 3 day precipitation forecast, the heaviest moisture will be found in the southeastern part of the country. The maximum of nearly 2″ to 3″+ will be aided by heavy rain and thunderstorms. The northern flank of the heavy precipitation band will be in the form of snow near the D.C. area. There is also a fairly decent swath of precipitation from the Pacific Northwest to the Upper Midwest. Some of this precipitation will also be in the for of heavy snow!



Winter Weather Headlines
The winter weather headlines with storm #1 will still be in place across the Mid-Atlantic Region through midday Monday. There is a chance of nearly 4″ to 10″ of snow through that time period. Also note the winter weather headlines that have been posted in the Northwest. That is from a secondary storm system that will eventually be responsible for several additional winter weather headlines across the Upper Midwest through midweek.

Here are some great stats that have been compiled for the D.C. area by my good friend Jacob Wycoff from WeatherBug – Great stuff Jacob! Thanks!

First:
Average snowfall is 15.4”
2014 we’ve had 23.1”

Past seasonal snowfalls:
2011-12: 2.0”
2012-13: 3.1”
We haven’t seen 23” in one season since 2009-2010, when we got 56.1”.

Second:
We recently broke our 1,090 days long snow drought of no snowfalls over 2 inches on 21 January. Since then, we’ve 3 snowfalls over 2 inches. Nothing for nearly 3 years, then 3 within 2 months.

Third:
Average Temps:
Hi  – 56°
Low – 38°
It hasn’t been an especially brutal winter like 2009-10, but it has been long and cold. The past three months, we’ve been below averages temperatures.
Jan: -3.8°
Feb: – 1.2°
Mar: -2.7°

Fourth:
Cherry Blossom festival starts on March 20th and runs through April 13th.
Peak bloom, defined as 70% are open, will be April 8-12, as forecast by the National Park Service. Snow is not expected to adversely affect the blossoms, nothing more than pushing peak bloom back a few days.

Monday Severe Threat
The best chance for any severe weather looks to be confined to places along and just east of the cold front Monday. This front will be placed in central Florida.

Here’s the severe thunderstorm outlook from NOAA’s SPC:

WIDESPREAD CONVECTION IS FORECAST TO BE ONGOING FROM THE SERN ATLANTIC COAST SWWD ACROSS NRN FL AND INTO THE GULF OF MEXICO…WITH SHOWERS AND THUNDERSTORMS EXPECTED TO STREAM CONTINUALLY NEWD ACROSS THIS SAME ZONE THROUGH THE DAY — RESULTING IN PERSISTENT HEAVY RAINFALL ACROSS THE NRN FL VICINITY. ALONG AND AHEAD OF THE LEADING EDGE OF THE CONVECTIVE BAND…A MOIST BOUNDARY LAYER WILL AID MODEST DIURNAL DESTABILIZATION WHICH — COMBINED WITH SUFFICIENT SHEAR SUPPORTED BY 50-PLUS KT MID-LEVEL WSWLY FLOW — SUGGESTS SOME RISK FOR ISOLATED/DAMAGING GUSTS WITH A FEW STRONGER CONVECTIVE UPDRAFTS. SOMEWHAT GREATER SEVERE RISK MAY EVOLVE OVERNIGHT — AS THE UPPER SYSTEM APPROACHES AND A GRADUALLY STRENGTHENING SURFACE LOW MOVES ACROSS THE PENINSULA. AS BACKGROUND ASCENT STRENGTHENS…A MORE LINEARLY ORGANIZED/VIGOROUS CONVECTIVE BAND MAY RESULT…YIELDING CONTINUED SEVERE RISK — PRIMARILY IN THE FORM OF DAMAGING WINDS — THROUGH THE END OF THE PERIOD. 


Temperature Outlook
Well, well, well… what’s new. Not too surprising that according to NOAA’s 8 to 14 day temperature outlook, the eastern two-thirds of the nation look to be much colder than average through the end of March. UGH!
