That’s more a winning scenario for along and west of 95 Looks like yet another storm that ends up fitting the climo mold. It's mind blowing how this keeps happening. Sorcery. Lol. I usually do ok in these setups. Looking forward to whatever happens. Biggest fear (huge qpf bust) is off the table. And everyone is already below freezing. 2 Link to comment Share on other sites More sharing options...
Herb@MAWS Posted February 18, 2021 Share Posted February 18, 2021 Starry night above me. Calm wind. Great for temps until clouds arrive. Currently 27 at 9pm after high 32.8. Link to comment Share on other sites More sharing options...

I am afraid I might not get a foot It's a good thing all 3 people who live there post on this board. The storm already paid off for me before one flake dropped. I am betting minimum 6 inches as long as the change over to sleet doesn't happen quickly. Link to comment Share on other sites More sharing options...

If the dendrites are big they'll clump up before hitting cold air again. Marginal sleet sounding. Like 1 degree above freezing tops? Warm layer is thin too. 1 Link to comment Share on other sites More sharing options...

ThePhotoGuy Posted February 18, 2021 Share Posted February 18, 2021 00Z IAD sounding showed a warm nose of 1.8C at the 809 mb level. This is around 1C warmer than what most of the 18Z models initialized. The 18Z Canadian Regional had the best initialization of the 18Z guidance with a warm nose around 1C with the 00Z NAM now having caught up to the warmer air aloft. Although, there is a lot of dry air at that level which would result in wet-bulb cooling once precip arrives, the trend in the models has been for a faster changeover to mixed precip Thu morning. Will be incorporating more of the 00Z NAM and 18Z Canadian Regional in our update tonight. These two models have verified the best with temps aloft this winter, especially with the mid December 2020 and Feb 10 mixed precip events. There has also been a trend toward a faster exit of the precipitation late Thu night across the region with precip only lingering across southern MD and in the upslope areas.

But see we have to read things that irritate us too. Now multiply that by the vast number who live where you do and you will see that your irritation is mild comparatively. So it’s probably best that you worry about your issues and let us worry about ours. 3 1 Link to comment Share on other sites More sharing options...

We say that every time. However, when the track of the storm and overall setup on the NAM is nearly identical to other models but shows father north mid level warm air intrusion, it’s typically right. Sadly. Hope it’s dead wrong here. Link to comment Share on other sites More sharing options...

It’s interesting how early it looks like the sleet line is advancing quick but then it gets knocked down. Maybe because of the rates? 2 Link to comment Share on other sites More sharing options...

I would expect cooling over night.. I think the 06z sounding should be more telling 1 Link to comment Share on other sites More sharing options...
