North, south, east or west most of us are in the game!

EPS members snow/sleet totals (inches) for the last 6 runs (College Park) through Feb 2 90th percentile: 9 15 12 15 12 16 80th percentile: 6 10 11 9 10 12 70th percentile: 6 6 9 8 7 11 60th percentile: 4 5 8 6 6 7 50th percentile: 3 4 6 5 4 6 40th percentile: 2 3 4 4 4 5 30th percentile: 2 1 4 3 3 4 20th percentile: 0.7 0.6 3 2 2 3 10th percentile: 0.5 0.3 1 1 1 1

When we shift (12z today or tomorrow makes sense), I'd suggest moving over all discussion of the very active January 25 - January 29 time period.

Still in the game although the start of any fun is delayed until next Tuesday or so. EPS members 360 hour snow/sleet totals (inches) for the last 4 runs (College Park) 90th percentile: 9 15 12 15 80th percentile: 6 10 11 9 70th percentile: 6 6 9 8 60th percentile: 4 5 8 6 50th percentile: 3 4 6 5 40th percentile: 2 3 4 4 30th percentile: 2 1 4 3 20th percentile: 0.7 0.6 3 2 10th percentile: 0.5 0.3 11

NAEFS time series for the next few weeks

EPS members 360 hour snow/sleet totals (inches) for the last 3 runs (College Park) 90th percentile: 9 15 12 80th percentile: 6 10 11 70th percentile: 6 6 9 60th percentile: 4 5 8 50th percentile: 3 4 6 40th percentile: 2 3 4 30th percentile: 2 1 4 20th percentile: 0.7 0.6 3 10th percentile: 0.5 0.3 1

I've bottomed out at 23 degrees - at least that's the lowest I've seen. don't have a max/min. The 00 EPS does show below normal high temperatures for a 9 day period beginning next Saturday.

The 00UT EPS still have numerous good hits in the 8-11 day range. The downside is that most of the ensemble members delay the start of any event until next Tuesday - about 24 hours later than the ensembles showed 2 days ago. For College Park, 1/3 of the members are snowless while 1/5 predict a MECS or BECS resulting in an impressive snow mean of 6-7" and a median of 4" Hopefully, we won't end up getting the mode.

12 UT GFS: Primary reaches Manitowoc at hour 192. Wintry precipitation yet to reach MBY. Cold air moving make that running away. Hour 198, rain. Hopefully, we pick up an inch or two between 193 and 194 I toss. It's still ensemble range.

00 UT EPS suggests that our best chance of snow is in a 2-day window beginning a week from Monday evening and ending a week from Wednesday evening. The EPS mean for College Park is 0.7" or greater for 4 consecutive 12-hour periods; the 2nd best its been this season.

I don't mean to be a pain here but could you use "discrete". Discreet brings back bad memories. My sister lost a spelling bee because she spelled indiscreet as follows: I N D I S C R E T E.

00 UT EPS suggests that our best chance of snow is in a 2-day window beginning a week from Monday and ending a week from Wednesday. The EPS mean is 0.7" or greater for 4 consecutive 12-hour periods; a first for this season. Hopefully, my post tomorrow will be identical with the exception of the 0.7 being changed to 1"

12/16 0.6 " (College Park)

The climate change tangent got me thinking of nordic skiing and a sign I saw this past January. Hopefully "forever" won't end sooner than the Doucettes' hope

Which is more likely, another December like this one or another February like last one? My hunch is that February 2015's weather was less abnormal but haven't run the statistics. Thoughts?

Remember Ian's article about how uncommon 1" and above snows are becoming at DCA. Well in today's Washington Post there is a non-technical article by Reid Wilson on California's drought that speculates that melting of Arctic ice may be 'contributing to a slowing of the jet stream contributing to colder wetter weather in the eastern U.S. and more persistently dry conditions in the west". I guess for every winner there is a loser. Kind of reminds me of spring 2010, when several hopeful posters here speculated that 2009/2010 could become the new norm or last winter when several scientific articles predicted that melting of Arctic ice could be responsible for warmer eastern U.S. winters and colder European winters.
