00:00So looking at our snowfall over the last 24 hours here, we have a pretty small area of the 6
00:06to 12.
00:06Again, our snow reports officially, the top snow report is 4 inches, but those can be a little bit delayed.
00:11So we will get closer to a foot in some areas when all is said and done by tomorrow.
00:16But it's not just the snow.
00:17I mentioned the freezing drizzle, freezing rain concerns in Boston.
00:21We have one report. These definitely are delayed.
00:24It takes some time to get into the storm report system.
00:26So I can tell you, Albany, we've seen reports on the ground with surface observations of some freezing drizzle certainly
00:33can cause some problems here.
00:35Like I mentioned, Boston, we're watching for that to potentially move in.
00:38You'll see why when we take a look at radar and clouds.
00:41So we have this line of the snow versus the pink where we're getting more of that freezing drizzle moving
00:46over Albany.
00:47It's working its way towards Boston.
00:50We could certainly start to see some of those reports, especially southern suburbs of the city.
00:55Either way, though, could create some slick spots on the roads.
00:59It's something you'll want to watch out for the rest of tonight.
01:01As we go into the overnight, we're still trending above where we typically would be this time of year when
01:05we look at our historical averages.
01:07However, these lows, still cold enough to support winter weather, at least north of D.C.
01:14Because we're in the low 40s there in D.C., 34 in Charleston.
01:18Very much depends on where you are in the region.
01:21We look ahead to tomorrow.
01:22Well, we have the snow showers in places like Buffalo.
01:26And then we have the snow flurries.
01:29It's a difference of where we see a little bit of accumulation versus just kind of that spitting snow that
01:33can be annoying if you're sick of winter,
01:35which I know a lot of people are at this point, especially with the winter that we've had in the
01:39northeast so far.
01:40So let's take a look at how all of this pans out on future radar and clouds.
01:45So we go through the rest of the weekend, still very widespread snow and freezing drizzle, especially for northern New
01:51England and into Maine.
01:52We get to the overnight hours.
01:54You're going to start to see things transition to that more snow showery phase.
01:59We're playing that out.
02:00Take a look.
02:01But we're not done yet.
02:02We see more widespread snow showers moving into central and portions of upstate New York.
02:06I'm pointing this out specifically because this is where you're more likely to get some light accumulation from those snow
02:12showers versus just not really adding much to what's on the ground,
02:16but seeing that snow continuously falling.
02:18Then our attention is going to turn south.
02:20This is going to become our higher impact storm as we head into our Sunday.
02:25So it very much depends on where you are in the region, what kind of weekend you're going to have.
02:29Northern portions, it's Saturday that's the bigger deal for you.
02:32And even that, not super high impact.
02:33It's tonight that's the higher impact situation, and this is not a major winter storm by any means.
02:39Along the coast, though, we have a nor'easter to talk about.
02:42So let's send things over to Jeff, kind of picking up where I'm leaving off.
02:45Yeah, and this is going to be a high-impact event, and there's been a lot of chatter about this
02:50storm, and rightfully so,
02:51because a few miles can make a big difference.
02:53A few dozen miles can make a big difference in trying to split hairs in terms of determining exactly where
02:58the surface low-pressure system will track offshore.
03:00And, again, the pieces, the players on the field are still in the western U.S. that will dictate this
03:06kind of behavior that we see with this storm.
03:09So here we are Sunday morning, 3 a.m., we've got snow falling in eastern West Virginia, snow beginning to
03:13fall in southwest Pennsylvania.
03:14This is the interior disturbance that's going to be sliding to the coast and ultimately helping to fuel the development
03:20of a new coastal low-pressure system.
03:229 a.m., we've got wet snow falling in Harrisburg into areas around Philadelphia.
03:26Rain-snow mix, big, very heavy precipitation there for some, but temperatures are going to be borderline.
03:33During the day in D.C., we may be hard-pressed to see accumulations.
03:36You can see the, at least, representation of what precipitation type we're dealing with.
03:41We're dealing with a pretty significant precip.
03:43We're into the yellow for rain and the medium blue for snow.
03:47So it's going to be fairly heavy, but temperatures will be borderline during the day in the interior.
03:52You'll notice, though, once we get into the evening and the night, this coastal storm begins to manufacture its own
03:57cold air.
03:57The sun sets.
03:58We get into it here along I-95 and especially near the coast.
04:03A few miles for the storm track can make a big difference.
04:06There's a benchmark of 40 degrees north latitude, approximately the latitude of Philadelphia, and the longitude 70 west south of
04:13southeast New England.
04:14If the center of low pressure passes over that area, that puts the big cities along I-95 in play
04:19for big-time snow.
04:20It's going to be close to or perhaps a little east of that location.
04:25So, again, the heaviest snow will probably be right along the coast on the west side of the storm.
04:29The storm's going to be strengthening Sunday night offshore.
04:32And we are looking at what may become a blizzard for Suffolk County.
04:36That's eastern Long Island.
04:37Cape Cod.
04:38Maybe, maybe even parts of coastal New Jersey if this really ramps up fast enough.
04:43But, again, there's a chaotic nature to what we're trying to forecast.
04:45We're trying to forecast if the center of low pressure is going to go, again, very close to that benchmark
04:50I talked about.
04:5120 miles west, 20 miles east.
04:54Not a whole lot of variance considering the players on the field are still way out in the western U
04:58.S.
04:58And then there's this disturbance that precedes the storm.
05:01That one moves through.
05:03But you'll notice the winds behind it deliver some cooler air.
05:06I don't want to say colder air.
05:07It's borderline chilly behind this first system.
05:10But these little blips of different color here, these are areas of what we call vorticity, measures of spin in
05:16the atmosphere.
05:17And if you're east of one of them and you're in a posture of rising motion in the atmosphere, we're
05:22going to see more clouds and rain production, snow production.
05:24So here we have a big dip in the jet stream.
05:26The two disturbances, the northern branch and southern branch feature, work together to amplify this dip in the jet stream.
05:31And then we get into business here with this strengthening coastal low, rapidly strengthening on Sunday evening.
05:37And that means widespread snow continues for the interior and increases for the coast with very windy conditions setting up.
05:44So how much snow are we looking at?
05:46Well, here we are with a pretty tight gradient here.
05:49I'm going to zoom in so you can see with a little more clarity.
05:51We're forecasting over a foot for Cape Cod.
05:53We're forecasting 6 to 12 inches for Pawtucket, Rhode Island, Suffolk County from Islip East, South Jersey from Tom's River
06:00down to Cape May into southeastern parts of Delaware, the Maryland beaches.
06:05That's a big snowstorm, 6 to 12 inches of snow, New York City 3 to 6, Philadelphia probably close to
06:103 inches.
06:11But again, there's a high end potential here that's really tricky to nail down.
06:15The worst conditions will certainly be along the coastline with a combination of wind, coastal erosion, flooding and snow.
