    February 1, 2019 Clipper Snow

    It has been fair heavy for the last hour on Capital Hill. I would have assumed that SN- in the city with temps in the low 20's but here we are SN.

    January 12-13th Cold Smoke Obs and Nowcast

    Are we expecting a pivot and the bands coming back through the east? I know they are weakening, but the HRRR and I think the NAMs should some sort of pivot. I want another inch.

    November 15-16 First Frozen Obs/Nowcast

    That checks out here on Capitol Hill, when the yellow returns come in goes to big flakes. But, right now its lighter and its sleet and a little snow.

    March 20/21 STORM Obs/Discussion- No Banter

    Pretty uniform 5 inches in Cheverly, which is 7.5 miles NE of the Capital. Trying to upload photo, but says it too large.

    March 20/21 STORM Obs/Discussion- No Banter

    We had a little sleet on the ground around 6pm. Now a nice coating of snow. Cheverly, MD
  9. Actually until the last 90 mins the unmoderated free fall was working.
  10. I am so snow deprived I got into it with airport weather observers about DCA's lost snow board (I work on the Hill). I like to track and some of the back and forth on the board is entertaining. I lurk, but if its cold I want it to snow. Please no one start a warmth tracking thread, because we will screw it up.

    March 1-2 wind event

    I saw some power flashes in the distance early this morning. Otherwise we have been lucky. I don't know if it's just this part of PG, but the east side of the beltway doesn't seem as affected as Western suburbs.

    We had the lull for a bit, but now the wind is back. Highest wind since about 5am.

    March 1-2 wind event

    This is pretty strong verbage from Sterling at 8pm. A wind shift to the west and northwest is expected behind the front and strong winds will accompany that shift. The gradient will continue to strengthen overnight causing strong winds. Winds at the top of the mixing layer continue to be modeled between 60 to 75 knots per latest multi-model consensus, peaking between 5 am and 12 noon, with mean mixed layer winds between 50 and 60 knots. Therefore a High Wind Warning is in effect for the entire region with gusts around 60 to 70 mph expected. Could see gusts even a bit higher than that...especially across the ridge tops. Concern is increasing for the Friday morning hours between 6 am and 12 noon for the strongest period of winds. A feature similar to a "sting jet" (Browning 2002, Schultz and Browning 2017) may cross the region during this time frame, increasing the threat for the 60-70 mph winds. There will also likely be some rain/snow showers around during the morning hours, including the Washington and Baltimore Metropolitan areas. Snowfall could coat some grassy surfaces but recent warm conditions and marginal temperatures suggest that paved surfaces will be wet. Following this period, strong and damaging winds will continue through Friday and well into Friday night before diminishing slightly toward morning. The fact that this is a long duration event and the ground will already be saturated means that widespread tree damage is expected along with power outages. This is going to be one of the most powerful wind storms in recent years. Through this evening...it is a good time to secure lightweight objects outside, and check flashlights and batteries as well as other items needed in a power outage.

    Given how many delays and closures we have had this year for minimal accumulations and how aggressive NWS has been in forecasting this, I thought more districts would have called it off for tomorrow already.

    PD3.5 Lite Obs and Nowcasting

    After sn+ there was a lull and now I hear pingers. It looks like close to two inches on the deck.
