ORH_wxman Posted February 26, 2014 Share Posted February 26, 2014 Snow can accumulate in May if snowfall rates are high. Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted February 26, 2014 Author Share Posted February 26, 2014 I've had light snow midday in early april accumulate 3" or so in philly back in 96. Link to comment Share on other sites More sharing options...
hazwoper Posted February 26, 2014 Share Posted February 26, 2014 Snow can accumulate in May if snowfall rates are high. This And....THAT is the only questiopn here. Based on rates....the 16-18" maps are soooo far off (based on the GFS). This is all I am trying to say. Just keeping it real. Link to comment Share on other sites More sharing options...
Brian5671 Posted February 26, 2014 Share Posted February 26, 2014 Sure it can. But during mid-day with light or moderate rates can be tough if the temp is near freezing. Heavy rates will accumulate no matter what. Link to comment Share on other sites More sharing options...

Ralph Wiggum Posted February 26, 2014 Author Share Posted February 26, 2014 With 2m temps in the upper teens and low 20s I can damn near assure u it will accumulate in early march unless we are talking flurries or something ridiculously light.

In fact, I am guessing we will, and a fair amount as well. I just think that based on time of year and rates as modeled the 16-18" output from those maps are a bit generous. that is all I am saying If this was a true coastal with high rates, the 16-18" would make sense.

RutgersWx92 Posted February 26, 2014 Share Posted February 26, 2014 It also has temps in the low 20s during that timeIf temps are that cold it will pretty much accumulate no matter what, even if the rates are light. Look at today for example. The sun angle influence, while definitely an issue when the temp is near freezing in March/April and rates are light, is greatly overstated by some on here.

Not with an overunning event you should've been more careful in making a statement regarding sun angle and QPF over a time period in march and a VERY cold air mass during the storm. the 16-18" snowfall is not far fetched at all Link to comment Share on other sites More sharing options...

marsplex Posted February 26, 2014 Share Posted February 26, 2014 Can meaningful lasting snow pack be created in March, i dont think so. On the ground for a few days, yes, Weeks.. no way. Link to comment Share on other sites More sharing options...

On the ground for a few days, yes, Weeks.. no way.this year is a completely different beast. Some of the weeklies show -8 temp departures from normal. Never say never...it could very well hang around for a little while. Link to comment Share on other sites More sharing options...

SnoSki14 Posted February 26, 2014 Share Posted February 26, 2014 Can meaningful lasting snow pack be created in March, i dont think so. On the ground for a few days, yes, Weeks.. no way. That normally has to do with the fact that average temps are getting toward and over 50F as March progresses. If March were to be very cold with temps well below normal and a lot of snowfall, then it could stay on the ground for more than a few days. I love how people act like if on March 1st, the sun angle goes up like 30 degrees in a day, as some shocking phenomena has occurred compared to February 28th.

Juliancolton Posted February 26, 2014 Share Posted February 26, 2014 How is the snow not going to accumulate during the day with temps in the upper teens and low 20s?? Please explain I think I get what he/she is saying and I agree to some extent wrt this upcoming event, depending on your location. Snow will easily accumulate given cold progged temps for most of the event, but assuming it's a drawn-out, impulsive train of precip like some models are suggesting, the sun will come out and your storm total will compact/melt in between bouts of heavier snow. Where combined 6-hourly measurements might yield 12-18", you will probably have noticeably less than that at the end of the storm. Link to comment Share on other sites More sharing options...
uncle W Posted February 26, 2014 Share Posted February 26, 2014 that is an interesting one. I'd like to see what that snow melted down to in that instance April 1982 leaves no doubt about snow accumulating during the day...temps in the 20's did help a lot...

But during any break in the snow , we could see some melting but probably not much at all with temps like that. Speaking in model output not end result bc this is still too far out.

hazwoper Posted February 26, 2014 Share Posted February 26, 2014 How is the snow not going to accumulate during the day with temps in the upper teens and low 20s?? Please explain sublimation. The solar radiation is stroner and stronger eveyday as we approach spring. And I am not saying it won't accumulate, I am just saying not as much as the maps of the model output would have you believe http://www.theweatherprediction.com/habyhints/203/ Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted February 26, 2014 Author Share Posted February 26, 2014 I believe phl had accumulating snow in may of 1979 if I have my years correct. They all blend together in my old age lol. Link to comment Share on other sites More sharing options...
