November 27th Storm (snow, sleet, rain - something maybe for everyone)

[ChescoWx]

Latest Wxsim forecast for NW Chesco has precipitation arriving by noon tomorrow mainly just light mixed precip with temps just above freezing. However by 4pm it has the temps falling to below freezing and staying there through 9pm (during that time 0.40" falls as ZR) then we transition to a heavy rain with 2.78" of much needed precipitation. Could be a very messy evening commute in the NW burbs tomorrow.

Not sure if it will be cold enough tomorrow afternoon/evening for any ice or mix in the NW suburbs of Philly...but perhaps overnight Wednesday / early Thursday we can get snow showers to whiten the ground.

Looks like the GFS trended towards the NAM / Euro again.. NAM wins another..

 

Temps will be very borderline up here throughout.

EC looks a bit more interesting with regard to something frozen on the front end along I-95.  Would like to see the GFS or NAM bite too before I get more interested.

By the time the precip arrives the surface and 850 freezing lines are both nearly up to I-80.

From what I'm seeing its nearly isothermal, 850 of 33F and surface of 34F, with 0.15" having fallen already.  Suggestive of mixing.

a very minor (50 mile shift east) could keep it below freezing here for most of the event.  Probably more freezing rain / sleet than anything else.   But with all that qpf....pshh

 

models still aren't that great handling trapped cold air in valleys.

I don't think precip makes it to Philly metro (at least, not as snow), but a coating to an inch is not out of the realm for the LV and NW NJ into the Pocs this morning.
