Still not the same of course but it's pretty damn cold all things considered. We are pretty dammed up from 850 down to the surface on the SPC mesoanalysis.

Normally I would say no chance with that stripe but a good bit has fallen and radar looks pretty sick. lol The yellows are pretty persistent over that area so it could be right. 3" of sleet would be fun by 3am.

Deck Pic Posted March 14, 2017 Share Posted March 14, 2017 30/28, Heavy Sleet. Picked up 1/2" of Sleet in the last hour. 2.0" total Link to comment Share on other sites More sharing options...
Jebman Posted March 14, 2017 Share Posted March 14, 2017 In the winter of 1993-1994, when we got the sleet storm that dumped 3 inches of sleet on Dale City. Overnight, the sleet hardened into a formidable sheet of ice. It was hell to walk on. I literally had to slide on it to get down hills. Lots of older people slipped on it and received grievous injuries. The temperatures would hit the upper 40s, even the 50s, little pools of water would form in this glacier, then just freeze again once the sun went down. it was like being way up in the Arctic. This storm has got a lot of moisture. It will dump prodigious amounts of snow, like in N MD where two feet could easily pile up. But in places closer to I 95 there will be sleet. I think some places could accumulate 6 to 9 inches of sleet. You know how some of the model runs were calling for 8, or even 10, inches of snow and sleet? Maybe they were referring to 8 inches of mostly sleet. I wonder if a FOOT of mostly sleet is possible with this storm. it has sure got the dynamics and the moisture! This will be a storm long remembered. Link to comment Share on other sites More sharing options...

nj2va Posted March 14, 2017 Author Share Posted March 14, 2017 Whoever described the sleet in the heavy bands as rock candy was spot on. Much larger IP than an hour ago and coming down furiously with more heavy bands right behind it. Link to comment Share on other sites More sharing options...

I miss it haha Wow.... I travel down West Watersville Rd quite frequently on my way to Mt Airy. It is a great area for winter weather. I could have done without the tornado this past summer, however.

I already am approaching 0.20" liquid since midnight with plenty more to come by 3:00 a.m. The model has my area in the first shade of light green.

Vik Posted March 14, 2017 Share Posted March 14, 2017 Metro is on Saturday schedule (train every 12 mins) and buses are on an emergency schedule (limited service). I can't see how OPM stays open. Still sleet in south eastern MoCo. Link to comment Share on other sites More sharing options...

Bob Chill Posted March 14, 2017 Share Posted March 14, 2017 HRRR shifted the axis of obscene precip east right over 95 and the cities. Looks like the banded structure may be tighter to the coast during the pivot. Link to comment Share on other sites More sharing options...
mdhokie Posted March 14, 2017 Share Posted March 14, 2017 2.25" before the sleet hit. Now at 2.675". 3/8" of sleet in the last hour. Link to comment Share on other sites More sharing options...
Jebman Posted March 14, 2017 Share Posted March 14, 2017 There is a small amount of freezing rain in this heavy sleet - and it is freezing right on contact. This sleet pack WILL harden. With all the moisture this storm is packin', makes this a potentially dangerous situation Link to comment Share on other sites More sharing options...

But yes, call won't be made until 4am. Yup. The odds of the fed gov't being closed tomorrow are north of 90%. Too many vairable conditions, too much risk to the morning commute, and too much possibility for significant additional accumulation during work hours that could lead to another commut-a-gedon scenario. This will be the only closure of the 2016-2017 winter. They're going to play it safe. Link to comment Share on other sites More sharing options...
