USCAPEWEATHERAF Posted February 25, 2019 Share Posted February 25, 2019 00z and 6z model runs today show a potential for a widespread 3-6 or 4-8" amounts of snow across SNE. We have seen this before with weaker lift in the DGZ, we need that mid-level shortwave to improve for better dynamics. EURO shows a cold air mass in place, leading to S:L ratios near 12-15:1 even for the Cape and Islands. Link to comment Share on other sites More sharing options...

I'm not the biggest weenie, man I wish those two systems in the mid-week period actually were allowed to phase, that southern low has a lot of moisture we need for this clipper system to produce. Thankfully we have the 6z and 18z EURO runs to mix in with the 00z and 12z runs. Link to comment Share on other sites More sharing options...

ORH_wxman Posted February 25, 2019 Share Posted February 25, 2019 Pretty good agreement now on all guidance of a nice isentropic lift event for most or all of SNE. There will prob be an enhanced band or two somewhere as well. This doesn't look like a big event...but high end advisory stuff is well within reach. A little early still for dissecting soundings but some of the guidance has a very deep DGZ on this so it's possible ratios could be high. Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted February 25, 2019 Author Share Posted February 25, 2019 Scott's favorite model the RPM latest run shows Cape and Islands receiving 4-6" of snow this mid-week period. NWS local forecast shows 2-4" Link to comment Share on other sites More sharing options...

ORH_wxman Posted February 25, 2019 Share Posted February 25, 2019 06z euro def juiced up a bit. Prob solid 3-6" for most of SNE. With good ratios, prob toward upper end of that. Link to comment Share on other sites More sharing options...

James doesn’t get it . Time and time again. Weenie goggles. Needs a Benadryl drip. You need confidence for 6” or More James for a warning. 3-6” doesn’t do it Link to comment Share on other sites More sharing options...

Yeah, but you're forecasting for an average and the highest probability of an amount. If 6" is on the extreme end it's not exactly the amount with the highest confidence. I think we'd need to see the models juice it up at least another category to increase the chance for WSWs. Link to comment Share on other sites More sharing options...

Never base a forecast off ratios if that is the only way to verify. There are a lot of NWS offices that could use that rule taped to the workstations. The call might be coming from inside the house on that one too, because as I've told Ryan and Scott, GYX is sitting at a cool 39% false alarm rate on warnings this season. Given that it's an 80% confidence product, you would expect a number 20% or less if you're doing it right. 1 Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted February 25, 2019 Author Share Posted February 25, 2019 9z SREFs mean over 2" of snow for HYA, up an half inch since the 3z run. Link to comment Share on other sites More sharing options...
