BLOG: Interesting Forecast

The forecast remains an interesting one this morning as a coastal storm about 100 miles east of Hatteras will churn north-northeastward today while gaining strength and spreading moisture into the Northeast. It still appears that this system will remain far enough offshore such that the city itself will see nothing more than a stray flurry or two, but light snow is expected along the coast of Delaware and the Delmarva as a shortwave trough approaches and helps to generate lift across the area. Given the amount of dry air in place across the region, the snow is not expected to be significant at all as a good deal of moisture would be required to saturate the atmosphere, but nonetheless a coating is possible along the coast. Chances of snowfall in the city remain at about 10-20 %.

Clouds will begin to break up tonight and into Monday with more sunshine in northern/western areas and winds will become a bit stronger, gusting to around 25 mph at times in the afternoon. This will act to keep RealFeel temperatures in the 20s for much of the day. Tuesday still has a little uncertainty associated with it, but model guidance continues to advertise a rapidly weakening clipper-like system passing through the region with nothing more than a stray flurry... but that essentially would be it, a stray flurry thanks to the strong confluent flow and a lack of any significant lift in the low-levels.

A fairly dry northerly/northwesterly flow should ensue for Wednesday and Thursday as an area of high pressure at the surface builds eastward from the Ohio Valley and an upper-level ridge develops across the Mississippi Valley. As mentioned yesterday snow chances return just in time for Christmas as a Pacific storm system crosses through the Plains and begins to amplify across the Southeast.

Stay tuned and have a great day!
