TL97 Posted February 17, 2021 Share Posted February 17, 2021 HRRR also has southern NJ getting .5 QPF of sleet in an hour, that would be quite the sight to behold Link to comment Share on other sites More sharing options...

clskinsfan Posted February 17, 2021 Share Posted February 17, 2021 I guess I will be the Deb on the HRRR. It is a quick burst and lengthy dryslot out this way. Big step back for those of us nw with the first batch. We'll see what happens after that. Back edge does flip back to snow out here though. 1 Link to comment Share on other sites More sharing options...

But here's my best guess: Nice clean format, and I really hope the 3-6" stretches down to include the 2-4" areas...those guys deserve it. If I'm being picky I'd move the title over to the top left portion of MD/WV where no one lives or cares about (I kid I kid). But for real. 1 Link to comment Share on other sites More sharing options...
osfan24 Posted February 17, 2021 Share Posted February 17, 2021 It comes in hard but it flips fast. It's basically the storm we've had 2 or 3 other times this year. Hopefully, we can keep the mix line south longer, but there is a definite trend on guidance to bring it north and bring it faster. Link to comment Share on other sites More sharing options...

I hear you but I dont remember a storm being as potentially heavy in soon as it starts like this one yet this year though...assuming it doesnt end up drier than modeled 2 Link to comment Share on other sites More sharing options...
Hypothetical 240 hour snow Posted February 17, 2021 Share Posted February 17, 2021 HRRR is a little on the edge of its "range" but it would resolve the higher rates and the possible dynamic cooling offsetting the warm advection aloft better than some of the coarser guidance so it might be on to something.

Rhino16 Posted February 17, 2021 Share Posted February 17, 2021 You all can party while I sit in the dark without power, and .5” of ice outside. I’m concerned for this one down here. Too soon to a few days ago for it to happen again. 5 Link to comment Share on other sites More sharing options...

Hopefully, we can keep the mix line south longer, but there is a definite trend on guidance to bring it north and bring it faster. I'm not sure I entirely agree with this - at least for MBY. I haven't ever hit (this year) those illusive 1-2 inch an hour rates (even for a short time). Even if the mix line comes in fast, this seems like it will be less "splotchy" and less spaced out than prior events. More precip in a shorter period of time than past events. 4 Link to comment Share on other sites More sharing options...

LeesburgWx Posted February 17, 2021 Share Posted February 17, 2021 Hasn't the HRRR been less impressed with past storms right before they started? Having it be much more bullish now has to be a good thing Link to comment Share on other sites More sharing options...

LP08 Posted February 17, 2021 Share Posted February 17, 2021 Probably too much HRRRRRRR talk but this is the worst sounding for the initial storm and it is after all the goods have moved through. To my weenie eyes, its below freezing or right at zero all the way up for the duration. The first sounding is niiice. Link to comment Share on other sites More sharing options...

Was the first thing advertising 4-6". I like having it on our side in the short-range, it's done really well this winter as far as I can recall. 2 Link to comment Share on other sites More sharing options...

I like having it on our side in the short-range, it's done really well this winter as far as I can recall. It tends to overdo cold past something like 36hrs, but within then it seems pretty grounded. Even the snow depth panel is ~3-5" for DC and points SW, which is pretty bullish for those types of panels. In the Dec 16-17 event, it initially went out of the gate being way too cold during WAA snow timeframe, but within 30hrs it continued to advertise that the initial thump would impact DC and immediate NW areas, while the NAM was still eroding the mid level cold much faster. 2 Link to comment Share on other sites More sharing options...

Warm Nose Posted February 17, 2021 Share Posted February 17, 2021 Let's discuss nowcasting. The radar in the deep south isn't what was modeled, correct? That will have an affect as models consume that info. Link to comment Share on other sites More sharing options...
