    Overall a period of deeper lift within the dendritic snow growth zone (boosting the fluff factor), thermal column cooling once the snow started (initially surface dew points were in the low to mid teens), and going with higher snow to liquid ratios (about 12:1 to 17:1). 
     

    Looks like we were on the high side particularly for some areas near and north of I-78, and on the low side across parts of northeast MD into southern DE. Overall to me this was not a classic norlun trough as there was no real heavier focused band of snow aligned parallel to the surface/inverted trough. There was synoptic lift that in conjunction with the surface trough resulted in a wider area of 4-6 inches of snow. 

    I hope everyone enjoyed the snow. I will enjoy my weekend off as it has been a long week. 

    Great job Mike!  Appreciate the effort from MT Holly.   Thanks for the explanation as well.

    Bravo to NWS Mount Holly! They stuck their nose out when others we mocking their storm totals map and their WSWs.  Here in Chadds Ford Township, PA, I ended up with 5.3 inches, which was the biggest storm in two years..... since the 5 incher in late Jan 2022. 

    Yep  MT Holly did an excellent job!   Hit the nail on the head, with a difficult storm to forecast

    Sorry, I have little respect for her forecasting skills. Don't know  why they still use Accu Weather, when they have their own mets.  We all know the reason she is there, and also Brittney Shipp is the chief met at NBC10.  I will take Glen, DT, and the NWS over those two any day of the week, seven days a week.  For the folks that have WFMZ,  Allentown, their mets are pretty good as well

    January 31-February 2, 2021 Major Winter Storm Observations

     Near Langhorne, Newtown border.  Hasn't snowed here since 11 PM last night.   Sleet at times, and now even freezing rain.  Temp up to 31.   Not looking good here.  Bordering on a bust.  About 5.5 inches here, including sleet.   On a side note, folks are calling out Cecily Tyson 6ABC on twitter  Her response, how about you just wait until the storms over, before telling me I am wrong.    That was this morning.
