Maybe a narrow area if there is enhancement with the front, but I don't see their reasoning. Unless they think we are getting 15-20:1 ratios. 20:1 don't think is happening but I think 15:1 is doable Link to comment Share on other sites More sharing options...
moneypitmike Posted January 17, 2020 Share Posted January 17, 2020 15 minutes ago, MetHerb said: Yeah, I think their reasoning in the discussion makes sense. The BOX forecast for me in northern Tolland County is 1-3" tomorrow afternoon and 3-5" tomorrow evening. That's 4-8". There's just as likely a chance for 4" as 8" and I think that's a reasonable call at this time considering there may be places over 6". Start high. You can always adjust upward if needed.

Gyx had a discussion about ratios this morning which I thought was interesting. Strong lift in the dgz for the whole area but we lose it later in the storm in snh. My only hope for better than modeled results is that the deep cold air and snow cover force some kind of coastal low to form faster than expected. The problem is I don’t know what the hell im talking about. 5 Link to comment Share on other sites More sharing options...

ORH_wxman Posted January 17, 2020 Share Posted January 17, 2020 I'm pretty skeptical of warning snows anywhere that is widespread enough for WSW but who knows. I suppose 6" might be common enough if this thump ticks up a little bit. 1 Link to comment Share on other sites More sharing options...

weatherwiz Posted January 17, 2020 Share Posted January 17, 2020 At this time don't see any need to make adjustments from this. Did receive a comment yesterday that I am probably too cute with southern CT there...which I am. Sometimes I like to be cute though. I always just feel though coastal CT somehow always finds a way to flip in these setups. Could have just moved the 3-6'' line farther south and then have a 1-3'' shading 1 Link to comment Share on other sites More sharing options...

As much as i hate the snowfall maps when I saw they were spitting out 2-3'' on 10:1 ratios I felt pretty good about going 3-6'' as I felt ratios may be more 13:1 to 15:1 1 Link to comment Share on other sites More sharing options...

I used to use overlapping numbers like 1-3/2-4/3-6 but then through the years of forecasting and making verification maps it never really works out that way. So for the past 3 or 4 years ive just been going with numbers like 1-3/3-6 that butt up against each other. I think 1-3 is probably a better range than C-2 as well, as with plenty of cold air in place even the shores basement is at least 1" imo. Doubt anyone gets away with this thing with just a coating of snow, even GON. Link to comment Share on other sites More sharing options...

I don't get why I like to get too cute with it. I think it's more to illustrate gradients and such perhaps. But I'm going to start canning this...unless of course it was a situation which really warranted it. 1 Link to comment Share on other sites More sharing options...
The 4 Seasons Posted January 17, 2020 Share Posted January 17, 2020 Using max temp in profile on BUFKIT, NAM/GFS start out high around 18:1 then they crash after a couple hours down to 12:1 then eventually 10:1, the average is right around 12:1 for the event. I don't use Cobb3 or 6 or 11 or whatever numbers that have been changing because i dont know what cobb is. Ill use max temp in profile to get an idea or use the slider for a straight 10:1 or 12:1. If anyone knows what Cobb ratio method is id be interested to hear it. (The blue line is snow ratio, the grey bars is snow falling (totals by the hour).

ORH_wxman Posted January 17, 2020 Share Posted January 17, 2020 I wouldn't get caught up in like one tenth changes to the qpf either. They could be meaningless. Look at h5 and midlevels instead to see if there's any support. Like I think the bump on the rgem is a little spurious. We're seeing a slightly better h5 shortwave not getting ground up quite as quickly, but I'm not sure I'd buy like a 2 tenth increase in qpf in spots. Some of it is the models trying to align a good leading fronto band too...and that could end up 30 miles either direction. Guidance typically isn't accurate enough to nail that with any consistency.

weatherwiz Posted January 17, 2020 Share Posted January 17, 2020 I think the cobb ratio is something that is more relevant to the mid-west than here...uses a higher avg ratio or something 1 Link to comment Share on other sites More sharing options...

They can always switch that to an advisory tomorrow. Link to comment Share on other sites More sharing options...
