Good Sunday morning to one and all :-)
Before I dive into the forecast, take a look at this satellite image from yesterday, following the final departure of the long-form storm system that impacted everywhere from the Central Plains to the Northeast. All the white coloration on the terrain is obviously snow...
On the bottom left, we see the 12"+ snowfall that appeared in the WV mountains, flaked to the west by our same-day melting, and to the east by many blown forecasts in DC, Baltimore, Philadelphia, and Harrisburg :-) Further up to New England, many more blown forecasts from this zany storm, but they are to the other side (in some cases 20-TIMES more snow than originally forecasted). The high-spot was just under 30" of snow at the Blue Hill Observatory in Milton, MA. If you look closely in the picture, you can still see the tornado scar left over from the June 2, 2011 event. No doubt if a similar picture was taken during a snow event in the tri-state, we could potentially see similar things (if only we got such a storm, but no dice).
|HPC - Surface Map - Sunday Afternoon|
High pressure to the east combined with low pressure to the west sets up a wind-flow zone that dredges lots of warm air from the Deep South and brings it up here. Enjoy. I expect thermometers to creep toward 70, and even over in the heat of the day. Beyond this, we'll be tracking those showers finally approaching from the west. The models have been slowing this down since yesterday, now here's the start time:
|NAM - Monday Afternoon||GFS - Monday Afternoon|
This should allow some outdoor workers to get some good hours in before the rain comes, though keep in mind if the models have jumped one way, they can certainly jump back (and we're still more than 24-hours out). Out ahead of the showers will continue the mild weather, so temperatures look to hit 60+ again. This system still wants to finish with a few flakes later on Tuesday, but it's not looking too great for snowfall.
|HPC - 5Day Projected Rainfall|
After this, a little bit of a dry spell. In the above map, most of the rainfall indicated occurs between Monday and Tuesday.
