In a mixing event for our area the best thing to do is just take the guidance with the fastest flip. It usually ends up being right. GFS is smoking the good stuff.
SE of 95 4-8
DC 6-10
NW 8-14
Seems like a pretty easy call and if DC gets 4 inches of snow and a bunch of sleet that'll seem like 6-10 anyway based on impact.
Normally with our phasing storms its reasonably clear how the ridge axis, timing of phasing, heights out in front, will affect the outcome but with this one it's been really hard to guess.
That's one thing I love not seeing on the models. The absolute worst thing the models can show is the WAA precip going north to PA and we don't get anything. In this situation it appears we will most likely get the WAA precip even if things shift either north or south.
Yeah, agree. We should be able to get a warning level snow even if the north creep continues. Which is great! We go years without warning level snows...
AI is 0.4 QPF by 12z and then 0.8 by 18z in DC. Changeover in between, implies about 6-10 inches in DC with ratios. Kinda the lower end of what guidance has been showing but acceptable nonetheless.
This is a QPF bomb so it is possible we get a foot of snow AND a ton of sleet. If we change over quicker maybe 6-8 inches and then sleet. Nothing is showing less than 6 inches of snow before a changeover. The later the changeover, the more we can pile up.
GFS is a later changeover and a change back to snow. Weaker and further south primary low. At 84 hours Euro has 1002 in TN and GFS has 1006 on the Georgia/Alabama border.
as depicted here this would be heavy sleet/frz rain, this would really do a number on the roads to finish off the storm. As others have alluded to would be really nice to trend this whole coastal south 50-100 miles and have this be powder.
You're gonna drive clear across our subforum during the peak of this storm? Driving in this area with 1 to 2 inch per hour snow rates is taking your life in your hands lol. I don't trust anyone around here in snow to drive safely.
Too early for this I know and the mesos will do better but the soundings for DCA on the Euro look like heavily rimed snow to me for a lot of Sunday when we're under pink, only later on Sunday is it a clear ice sounding.
