The weather service says to never measure the snow or lack thereof on a hill - especially south facing hills - if you have both covered and non-covered spots you take an average of the covered vs non-covered

Today will mark our 25th day with snow cover >1" here in NW Chester County PA. In a normal winter season we average 31 days of snow cover (1894 to Present). For many the best measure of a good winter (for a winter enthusiast) is the number of days with snow cover - so you may be asking what are our top 10 greatest snow cover winter seasons? Well wait no more the answer is below 1904-5 (74 days) 2013-14 (72 days) 1995-96 (69 days) 1960-61 (67 days) 1963-64 (64 days) 1947-48 (64 days) 1919-20 (63 days) 2014-15 (62 days) 1909-10 (59 days) 1986-87 (57 days)

Heaviest relative precip of the day here in NW Chesco...transitioned from some spotty ZR to now all IP with the heavier precip - temp has continued to slide now down to our low for the day of 25.3 DP 15.9

Temp continues to fall here in NW Chesco but with only some light ZR and a few ice pellets from time to time - temp down to 26.1 down from high of 28.3 at 11:40am

Just started to lightly sleet here in NW Chesco temp at 27.6 DP 10.0 - of interest temp has dropped 5 degrees in Sea Isle City NJ and even ZR now at the beach

This low level cold is not going anywhere if you are N and W of the fall line especially with a solid snow cover in place - models will overdue LL warmth in these situations....

I too grew up and was living in the Great NE Philly on Waldemire Drive near Red Lion Road. I just remember they kept upping snow amounts - my main source back in the day was Eliott Abrams and Accu-Weather on KYW radio. Plus like you Jim O'Brien was the guy that got me into the weather....."it's gonna rain like a hose on a flat rock" That was back in the day before weather was a major part of TV news....and the on air weather folks were almost never professional METS just personalities like Jimbo! Back then sports used to be a bigger part of news than weather. I really think ever since the Blizzard of 1996 when all of the stations covered it all day and got huge ratings they figured out how good weather can be for increased eyeballs!

The obs from Chester County for Feb 1983

The biggest issue with this thread and why we MUST change the title is this was way too early and was not in fact Presidents Day in 1983 - that was 10 days later....it was a great storm. The biggest snowstorm in my life up to that point but it was not President's Day...just trying to be accurate!!

I always will take sleet given a choice....remember sleet of course still accumulates and counts as snow.....just accumulates at 3:1 on average vs 10:1 - plus no one loses power!!

Ended up with 2.0" in East Nantmeal Twp. in NW Chester County PA with (0.18" w.e.) Monthly snow now at 23.4" (+17.5") and Season to date snow at 38.9" (+16.1")Also snow covered at beach in Sea Isle City NJ - most snow they have seen this year down the shore!

Midnight Obs East Nantmeal Twp - Chester County PA Snow 28.2 Snow so far 1.0"

Flakes getting a bit larger here in NW Chesco temp down to 28.4 - will measure at midnight but a solid coating so far

Coming down nicely here in NW Chesco in East Nantmeal Temp 29.3

I post on 4 different forums - but this one is the most laid back - the others all have some drama based on mods....

looking at WB maps a little less in central areas and a little more toward the NE toward NYC......not a huge change either way but with potential good ratios these maps may not be that helpful anywho

12km NAM actually ticked less qpf on the North and reduced snow amounts....the "north trend" may be over....

Actually a simple feat...I remember a storm where we started at 3 degrees and 2 hours later it was 25 and IP and 1 hour later 27 and ZR....it of course has nothing to do with surface temps - there are no roadblocks to warmth above the surface. One of my favorite memories was in January 1994 when I was in King of Prussia and my thermometer read 24 degrees with heavy rain - the ZR accumulated as quick as I could chop it off my car - which at the time had those pop up lights.

I like a nice 12z ICON / NAM blend - really liking the ICON of late.....nice moderate hit for many esp. from Turnpike on south in my current view.
