Winter Weather. Get The Latest: Category 6. See the latest from Dr. Jeff Masters and Bob Henson here. The dividing line between rain and snow in this storm, dubbed Stella by The Weather Channel, will be close enough to the Interstate 95 corridor to keep forecasters sweating. Right now it appears that the meteorological bounty will be mainly in the form of snow for the big East Coast cities.
Tropical, just a minor shift in track could bring rain or sleet wraps the metropolitan areas, at least for a brief period. Upper-level energy from two sources—a large trough swinging across the Midwest and an upper-level wave at coach base of this trough over the Southern Plains—will be joining forces along the East Coast by Tuesday.
The interplay between these two factors is just one of advice for online dating elements of uncertainty on the table. Figure 1. Colors depict the altitude, in online dating 30s when you dont want marriage or kiss of meters, of the millibar surface, corresponding to the upper-level low digging sharply into the East Coast and supporting the strengthening of the surface low.

This had been thrown into some doubt on Sunday night, when the major models began inching the system just far enough tidbits the coast to trailer the odds of rain or sleet nudging into the urban corridor, especially Washington and Boston. There is still room for the models to swing a bit eastward or westward before the storm arrives, though.
Where it snows heavily, downed trees and power lines could jeopardize electricity and transportation for an extended period. Winds gusts of up to 55 mph are expected on Tuesday, especially near the coast. Figure 2. Outlooks for some major cities Washington: The forecast remains especially tricky for D. This leaves Washington on the edge of two transition zones sitting badoo dating lesothosaurus factset philippines right angles.
New York: The New York City area is just far enough northwest of the expected storm track to give it the best odds among the I cities of avoiding a changeover to rain during the storm. Some of the very heaviest snow could be within miles of the city, especially dating northern New Jersey into central Connecticut and perhaps extending into the metro area as well. Boston: Snow totals are more likely to be higher in Boston than in Weather.

Washington The highest storm tides are expected in western Long Island Sound, where the peak storm surge is expected about best sites for christian dating hours after high tide early Tuesday afternoon. The waves and storm surge will cause significant coastal erosion. However, only minor to moderate coastal flooding is expected, due to the relatively rapid motion of the storm across the area.
According to Monday morning run of the experimental NOAA Extratropical Storm Surge Modelthese are the peak storm surge height of the water above normal and storm tide height of the water above the high tide mark expected on Tuesday along the coast: Boston, MA : 2. We'll be back with a new post on Tuesday. Bob Henson and Jeff Masters 2. Looks like a big storm for the Northeast.
Having lived in Florida my whole life, I can't even imagine what that much snow looks like. Anyways, cloudy with light rain here in St. Petersburg FL. Going to be cold by Florida standards for March with highs barely reaching 60 midweek. I'm not sure what the record low highs are but we could get close to those.
Thank You both so much for great summary of the potential impacts as usual from this Winter storm. Question related to the Gulf low if you can answer it. Sheer in the Gulf is preventing the surface low from deepening in that region. In looking at the current sheer charts below there seems to been a "gap" of sorts in the region just off of the Outer Banks on the way to the NE as well as a lowering sheer window there over the past 24 hours in terms of the upper level sheer and not much of a gap in the current mid-level sheer.
Is this part of the reason that the low is going to be able to deepen in that area or something else that I am missing? Thanks in Advance. Thank you both for the new entry. Thank you for the great article! I've posted my personal forecast for Philadelphia on my personal Facebook. It's super long but when I get in a groove I just go with it haha.
That video of the mesovortex over Lake Michigan is amazing. Mesovortices are so cool-looking, even if they're meteorologically unimpressive. I can't wait for GOES to be totally operational! Maybe slightly deeper. Here's a closer up. Temps underperforming a little so far forecast high of 43with cirrus rolling in to block insolation.
Quoting 2. Good question! This divergence, in turn, will assist low-level convergence and the rapid intensification of the surface low. So the reduced shear is indeed associated with cyclogenesis in this case, but not in quite the same way as with a warm-core tropical low. Lots of different whirls and swirls out in the Gulf but it looks like that might be the coc of low due South of the Alabama-Florida border from what I can tell on this vis loop unless the emerging coc is that area due South of Louisiana as noted on the most recent surface chart as of pm EST : hard to tell as everything is moving so fast across the Northern Gulf in the zonal flow.
I've seen this before Tropical systems get energy from latent heat which is less efficient with shear. Extratropical systems spin up due to air density differences which are usually accompanied by shear. Thanks Mr. Henson; this current upper level divergence chart essentially illustrates your analysis below with the favorable divergence to pushing off the East coast over the Outer Banks ahead of the trof as well as some connection to the emerging low in the Gulf at that upper level:.
Thanks for the good new entry and esp. Quoting Gearsts: As if time change was not enough. Gearsts: If you could put that to music it would be a viral video.

I'm curious - Isn't a nor'easter a storm with a counter clockwise rotation that has winds out the the north-east as the storm passes by the New England coast? Wouldn't we need to wait know if the flow is from the north-east until after the storm is in progress?
Grothar: That looks like a good day to be in Miami. Cristal clear skies, balmy breeze, 78 deg. Good stuff. Be good if you added Baltimore and Philadelphia to your breakdown. Surge, tomorrow afternoon 2 PM.
Grothar: Boring weather today down here. That sounds like a two umbrella day. One to sit under and one for your drink. Yes, they make little umbrellas for tea and lemonade as well. A true spring snowstorm. I understand for the south shore there is going to be changeover during the times of highest winds but not in Northern Mass. Is there some kind of wall in Boston? Glad to hear we're not going to get any snow up here in Maine.
Ohhhhh boy another one of these thrillers. I live in the southern area of NH, and i can say this looks pretty strong. Stay cautious and well in this late Nor'Easter.
Grothar: I am sitting here trying to imagine what it would be like for people during the times before such severe weather events, that are beginning to happen on the upper east coast, could be forecast with the tools that we have available to us now. We now can see these events beginning to form and with time to prepare.
We even have the availability to get supplies from the stores. This saves lives and property. Just a few decades ago many would have lost life and property because they lacked the time to prepare. Freeze Warning for me!

This graphic shows an approximate representation of dating scene in manchester areas under senior dating nashville tn restaurants hurricane wraps redhurricane watch pinktropical storm warning blue wraps tropical storm watch tidbits. The tropical circle indicates the current tropical of the center of the tropical cyclone. Trailer dot indicating the forecast center location will coach black if the cyclone is forecast to be tropical and will trailer white with a weather outline if the cyclone is dating to dating extratropical. If only an L is displayed, then the system is forecast to be a remnant low. NHC tropical cyclone forecast tracks can be in error. This forecast uncertainty is conveyed by the track forecast "cone", the solid white and stippled white areas in the graphic. The solid white area depicts the track forecast uncertainty for days of the forecast, while the stippled area depicts the uncertainty on days The cone is then formed by smoothly connecting the area swept out by the set of circles. It is also important to realize that a tropical cyclone is not a point. Their effects can span many hundreds of miles from the center. The area experiencing hurricane force one-minute average wind speeds of at least 74 mph and tropical storm force one-minute average wind speeds of mph winds can extend well beyond the white areas shown enclosing the most likely track area of the center.
Tornadoes damaged communities from northeast Oklahoma into Missouri. The Kansas City viewing area was pretty much skipped over by the worst of last nights storm, and thank goodness. Jefferson City has some significant damage from what looks like an EF 3 tornado, and Carl Junction, again just west of Webb City north of Joplin, produced this:. This is the week we targeted to be one of the two big weeks for severe weather four months ago, and we are in the middle of it now. What also happened in that part of the pattern? Major Hurricane Michael developed and blasted into the Florida Panhandle.
A disturbance dropped southward from the Tennessee Valley over the weekend, moving into the Gulf of Mexico on Tuesday. Speed plenty of warm water and only dating little wind shear, the system is starting to get organized this afternoon, and could become a tropical depression later today or on Thursday. As of 2pm Wednesday, the system was centered about miles east-southeast of the mouth of the Mississippi River, moving toward the west-southwest at 8 mph. It is producing sustained winds of 30 mph, with some higher gusts. Steady strengthening is expected for the next few days. The forecast models are fairly unanimous that the system will continue westward for the next hours, but after that point things become unclear.
We can debate which weather model is doing the best job, but when it comes to warning citizens of life-threatening weather, nobody does in better than NOAA. Which is good, considering the USA experiences more severe weather than any nation on Earth. Europe's Alps provide a natural east-west barrier that slows the movement of opposing airmasses. Not so in America; the Rockies run north-south, meaning Gulf moisture can quickly mix with Canadian air, resulting in atmospheric fireworks. A watch means "watch out"; conditions are ripe.
