The NAM is at the other end of the extremes with perhaps the GFS para offering a more realistic middle ground (and more of a light sleet to light snow for most of us scenario, instead of freezing rain) My worry is that the pros at NWS are favoring the NAM.

psuhoffman Posted February 18, 2021 Share Posted February 18, 2021 6 minutes ago, Winter Wizard said: Biggest takeaway from that is the mid-levels are about a degree warmer which is not a good sign. Being drier does mean more radiation cooling so while it’s not a bad thing, doesn’t mean much if the 850s torch. True...but from the sounding the extreme dry layer coincides with the warm layer. There is a really warm but dry layer around h8. But my point was if the NAM had that layer at 0C at 60% humidity and in reality it was +1.5C with 40% humidity...in the end the wet bulb temp (which is what really matters) is about the same so the error seems insignificant imo compared to the press its getting. 1 Link to comment Share on other sites More sharing options...

I doubt we get anything heavy but could tack on some additional accumulations if the precip is heavy enough to mix out the warm layers left over. 4 Link to comment Share on other sites More sharing options...

Bob Chill Posted February 18, 2021 Share Posted February 18, 2021 Imo- models have already set the boundaries and they cant replicate exact weather. Especially with riding such a tightrope with ptypes. Models arent all over the place either. There is a common theme through all guidance with the only big question being a razor thin ptype situation for most. Real time will tell the story there. Qpf amounts are close enough across all the models. Instead of hanging on model runs that wiggle back and forth, just imagine how your yard does with these events and be honest lol. You're probably right. The warm nose/layer before noon is pretty thin. It's also barely above freezing. 1 degree one way or the other is make or break snow/sleet. I'm in chips fall mode. A case can be made for more snow/less sleet and vice versa. We'll see soon enough 10 Link to comment Share on other sites More sharing options...
Deck Pic Posted February 18, 2021 Share Posted February 18, 2021 I'd probably blend the 18z Euro (likely too dry), the 12z Para Euro, and the 3z HRRR (running now). Throw in the 0z Canadian which is wet and a tad warmer I'd toss both GFS's and both NAMs...... Link to comment Share on other sites More sharing options...

WEATHER53 Posted February 18, 2021 Share Posted February 18, 2021 M*tt i have not read anything for hours so will catch up but I think you say you never like it when precip shoots up into PA from our west and then curls eastward all the way to far eastern PA and well east of DC at that point! did I get it right? do you have that concern tonight if I did ?

If you tone down the mid level warm layer by like 1C the 12k NAM matches the Euro (as a slightly wetter version) pretty well actually. 1 Link to comment Share on other sites More sharing options...
