jayyy Posted January 4 Share Posted January 4 Forecasts are always a range.Thanks, I know. Usually their maps are a bit tighter than 4-8” though. But again, it makes sense given where things stand currently. Link to comment Share on other sites More sharing options...

I like 4-6” for you with a potential for up to 8”. I think you’ll have some really good ratios to work with most of the storm. 7H FGEN should be best along the M/D with the 85H FGEN further south. Someone in MD/VA/DE is getting 10+ out of this. 6 1 Link to comment Share on other sites More sharing options...

This is the national blend of models, takes into account many of the top global and CAM models along with some other inputs. You can search up on precisely what it is and how weighting works.

Hoping of course for 6 plus. Anything less than 4 will be disappointing considering how much time we have vested in this event. 2 Link to comment Share on other sites More sharing options...

MillvilleWx Posted January 4 Share Posted January 4 1 minute ago, winter_warlock said: Does LWX actually use this model for their forecasts? Ohhhhhh yes. We don’t use the snowfall verbatim, but we do utilize the QPF as a base point and generate our own ratios with the NBM mean Snow Ratio a typical starting point. It’s all about know how to interpret the model and use to your advantage. It’s probability fields are also solid. 9 1 Link to comment Share on other sites More sharing options...

Sterling/Ashburn area should stay most, if not all snow. Hopefully the early morning hrs on Monday are nice and thumpy 2 Link to comment Share on other sites More sharing options...

You and PSU should be in a good spot for good ratios and a decent band that setups up along the topography. This is usually a good storm for one of those. 2 1 Link to comment Share on other sites More sharing options...

That’s been my optimism here around ski liberty. Elevation and N/W areas will have a ton of good h7 forcing and great ratios. We’ve seen the deathband set up a lot here. Even last year I did and grabbed 6” in a storm where Westminster had 0. 2 Link to comment Share on other sites More sharing options...

Seems like they considered our local climo and a blend of models for that call. Yeah that looks like a really good map. LOL HRRR is a beat down. 10 inches by afternoon and looks like part 2 forming. 3 Link to comment Share on other sites More sharing options...

It has a nasty dryslot and drives the primary up into central WV. But this is right at that point. No clue what it would do with the ULL after this. But a serious hit on the front end. And should make the northern crew feel a little better. 4 Link to comment Share on other sites More sharing options...
bncho Posted January 4 Share Posted January 4 I like 5-8" for my area. Not going too high or too low because of the model uncertainities. Link to comment Share on other sites More sharing options...

Question for the Mets is, on average, as I know every storm and model performance is different, when does the HRRR reach its credible range?

Are they probably out of their most accurate forecast range? Yes. Am I still going to cling to them? Yes. 1 1 Link to comment Share on other sites More sharing options...

No clue what it would do with the ULL after this. But a serious hit on the front end. And should make the northern crew feel a little better. All I’ll say is this… if I had no access to surface maps and just saw pressure, h5 and mid level maps, I’d assume the surface truth would be a nice hit from S PA to N VA. Not a big high pressure dome to constrict the precip shield and I’d think with the vort set up this would be a juicy storm. 3 Link to comment Share on other sites More sharing options...

It’s beautiful up there One of the best places to be when it snows. I’m tired of hearing the guns going and seeing the little snow plumes from my yard without having real snow cover. We’ve maximized a few events dating back to last year and the event in 2021 when the Catoctins and south mountain corridor jack’ed. 1 Link to comment Share on other sites More sharing options...
