Yes, freezing rain accrual is a self-limiting process UNLESS you have a constant, reinforcing supply of shallow cold air... In other words around here, you need a strong and persistent CAD for the duration that doesn't erode or retreat.
Don’t fret too much by looking at long range. Remember the long range showed this being a monster storm for us. Things change.
we still have a good amount of time. Yes it does get more difficult but February and even March have produced big ones.
3K NAM looks decent for Wake. Nice 6-8 hour period of light snow, taken verbatim. Granted, boundary layer temps are above freezing at the onset so a lot of it melts on contact...
I think an inch on the ground would be a win for Wake.
I put "bad" and "good" in quotation marks because it is subjective (whether you want snow or don't want snow).
I just meant that sometimes we praise the NAM when it shows what we want, but discuss how it is inaccurate when it doesn't show desired outcomes.
I think the last few weeks has shown that the NAM is not reliable at all. Brad P even mentioned concerns about its reliability over the last few years since they are transitioning to FV3 and HRRR.
If you throw out the "bad runs", you also need to throw out the "good" runs.
Still plenty of time.
Nothing has really changed over the past 2-3 days if you look at the big picture.
Still looks like a rain/snow event with light amounts possible over central NC.
Great article about how ensembles work if anyone is interested. https://www.wral.com/how-wral-meteorologists-use-ensemble-forecasting-to-determine-the-chance-of-1-or-3-snow-in-your-town/20099023/
From Mike Maze: Many folks have been reaching out about the possibility of a major winter storm this weekend. Today's model runs are not showing it at all. Here's a look at the European Ensemble probabilities for 1" of snow ending Saturday night. Does not look good to me right now.
Ensemble map shows 26% chance of 1" of snow for Wake.
