Two Clippers May Deliver Snow Showers Late this Weekend into early Next Week

I wanted to provide a quick morning update for my fellow snow lovers.  The European and Canadian models are in pretty decent agreement this morning that two clippers may impact the DC Area over the next five days.

The first clipper system may provide scattered snow showers Sunday night into Monday:

  • The image below (courtesy TropicalTidbits.com) shows a “bowling ball” of vorticity (spin and pretty impressive lift) moving across the Mid-Atlantic.  The right-front quadrant of the jet stream provides and area of upper-level divergence or lift and may very well aid in some scattered snow showers making the trip across the mountains and into the Metro Area on Sunday night into Monday.

 

  • Notice in the same image the bright colors moving into Minnesota… that is a second and potentially more potent upper level disturbance with a stronger clipper system at the surface which may track just to our south on Tuesday possibly touching off a period of moderate snowfall.

A second and possibly more potent clipper (aided by a very strong jet streak aloft) may dive south out of the midwest possibly tracking just to our south on Tuesday.  This system could provide a period of accumulating snow to our area on Tuesday.

While neither of these systems are forecasted to provide hefty snowfall totals, the second system on Tuesday may drop an inch or two if an ideal track (just to the south of the Metro Area) can materialize.

    Just looked at the 12Z GFS and it looks a somewhat better for measurable snow in the DC area with the first clipper system. They actually get a weak coastal storm going and the upper trough is quite powerful.

    Going to February, the pattern is interesting with a double block setting up, one over Alaska and a weaker one over eastern Canada and Greenland. The Alaska block allows an Arctic connection to bring down cold air masses and the eastern block is favorable for storminess. While the longer range GFS shows no major coastal storm, there at least should be chances for some snowfall in the area, at least snow changing to wintry mix situations.

    It sure looks much more interesting than it did a week ago!

      I couldn’t agree more. I’m betting the Euro and Canadian have a much better handle on Sunday Night- Monday clipper with hopefully a dusting to 2″ depending upon where the bands set up. Wednesday’s system looks to go north of us… but that sets up what is finally looking like our chance of a real snow storm next weekend!
