Every flake will count in this airmass. I tend to agree. Although the flip is being modeled sooner and sooner with each run. 1 1 Link to comment Share on other sites More sharing options...
MillvilleWx Posted January 24 Share Posted January 24 Final Forecast for the Storm Some adjustments were made to reduce snow a touch and increase sleet which is a lower ratio component of the forecast. Still will be a formidable storm with some ice accretion added for good measure. A lot of the snowfall range should be take for a south to north crescendo with higher ranges more likely to the north of the lines presented. Will not be perfect by any stretch, but gives a good proxy. High impact event regardless as cold air behind the storm is very legit and we will struggle to break freezing for several days post storm. Be warm and safe everyone! 26 1 2 Link to comment Share on other sites More sharing options...

This will lead to widespread significant snow beginning this evening, with the potential for ice Sunday especially south of Highway 50 and near and east of Interstate 95.

paulythegun Posted January 24 Share Posted January 24 It would be cool if a Met from NWS could tell us why they think NAM is wrong.My guess...they have like 6+ other hires models to look at that are better than NAM, if you include all the experimental ones.

EDIT: Obviously includes sleet at 10:1 This was wetter than 00z. Really dirty, but if you take the 06z RGEM changeover times and maybe go an hour earlier because of the trends, maybe metros can touch ~0.7in QPF before the switch. With downside risk of course... 1 Link to comment Share on other sites More sharing options...

The grocery stores win again You want a BIG snowstorm, you can't have the primary coming up the Appalachians. Our BIG ones form in the Gulf of America and then reform around HATTERAS and move N or NE up the coast. We'll be lucky to get 8 inches in the metro area with this one. 4 2 Link to comment Share on other sites More sharing options...
