Boxing Night Snow/Sleet/Ice Dec 26-27 Storm Thread/Obs.

[Philadelphia Wx]

Is it possible for anyone to tell me the timing of this event? Will I be able to drive around 10 a.m. on Saturday in upper (far) northeast Philadelphia? Hope someone replies. I have someplace I have to be, and am very nervous I won't be able to get out of my house! Thank you so much!

It looks like only Chester and Delaware Counties in PA are not included in the WSW. I get these areas won't hit the snow thresholds but suspected due to travel issues they would issue a warning and then move it to a WWA tomorrow. But what do I know...

I’m fairly certain Mt Holly will make adjustments tomorrow to the Watches and or Advisories. I can see them them converting to Warnings even if areas don’t meet the snowfall criteria due to the IP/ZR accums.

Personally I think you'll be fine (Philly)if you take your time. Then again, I'm the type of guy who likes to drive in horrendous conditions even when media is urging people not to drive. 

Overall, no one knows but you should kinda see which way we're headed by Friday...

throw this map out. No way does this storm produce the mixed lines like this. None of these boundary lines follows physical geography. What a waste. Historical weather patterns in my lifetime point to the evolution of the storm producing pingers in the last two hours of the storm event, then to a quick shot of freezing rain and then the final cake frosting of freezing drizzle in the LV with a normal thump of 6-8 inches of snow. That is a safe bet right now. All I can say  is it will be one hell of back breaking shoveling event. Snow blower special indeed.,  Under a winter storm watch now too

 

Also very rarely will a storm flip back to snow from ZR or sleet. Unless it’s an intense storm, the warm nose will take over and not budge

I think what will be interesting to watch with this storm is if it really does over perform. It’ll show what we can expect from storms for the rest of the winter year.

I wish it was that simple...

Probably the most accurate looking map I’ve seen

add 3-5 inches to the snow totals  in the purple and state that sleet totals maybe bring the final totals  down  and you would be spot on
