    I feel like our running theme the past few years is who can call out Winter's Over the quickest. I feel like someone just said we're running out of days in December... it's December 7th. Enjoy the journey. 

     When we are at January 15th, and there is no tangible signs of colder weather progged, you can pretty much kiss winter goodbye. Otherwise, by the time a cool down would start, you have very little time left, unless a complete long term pattern change occurs.

    https://www.washingtonpost.com/weather/2020/10/28/hurricane-zeta-track-louisiana/

    Flight-level winds during a midafternoon Hurricane Hunter reconnaissance flight hit 138 mph; extrapolated down to the surface, that would suggest 101 mph winds at the surface. A dropsonde, or probe, released shortly after found a surface wind of 115 mph in the southern eyewall. That would indicate Zeta is near or at major hurricane status.

    The National Hurricane Center did not upgrade Zeta in their most recent advisory, raising the potential that the measurement was suspect. Regardless, Zeta continues to increase in strength and could approach Category 3 intensity as it makes landfall.

     

    NHC: 115 mph winds? Naaahhh, we toss

     

    Okay, so riddle me this.  I was watching TWC right before landfall of the mainland.  The coast was already in the eyewall.  Gusts were only around 50 mph on the beach.  I checked the New Orleans Int'l Airport and they registered one 68 mph gust with sustained winds only at 40 mph, at any one point.  How can this be with winds around 110 mph?  Are we really classifying the intensity of hurricanes correctly?  As I found out, the storm surge is probably the most destructive part,  but isn't the the impact at the surface the area to classify?

    Yes. The land is very warm and in many of the areas it's going to run through also quite wet from the last few weeks of heavy rains. There should be plenty of heat energy to be gained from the warm land and it will be wrapping in lots of moisture off a very warm ocean just offshore. It's going to be an interesting one to watch.

    Morning thoughts...

    Isaias remains on track to pass through the region later tomorrow into tomorrow night. The guidance has shifted a little to the west overnight, but the general idea of passage over the Chesapeake Bay across New Jersey and then into southern/central New York State still remains reasonable.

    With some interaction with a trough, the potential exists for a period of baroclinic deepening. This deepening will likely help the fast-moving system retain a measure of its strength as it passes through the region.

    Rainfall amounts from New York City eastward will likely need to be reduced, based both on Isaias' track and somewhat faster forward motion than had been forecast yesterday. An area of 3"-6" rain still looks reasonable, especially for cities such as Allentown, Baltimore, Philadelphia and Washington, DC.

    In its wake, the western Atlantic ridge that helped steer it along its inland course will likely result in a rebound of temperatures. The predominantly warmer than normal pattern will continue. No significant cool shots appear likely through at least the first half of August.

    As a closed low opens up, much energy is released.  This energy many times is translated to speed of movement of the system.  I would think it would be difficult to project if this "opening of the closed low" would intensify the system for both precipitation amounts and wind.  I always feel wind is over forecasted.

    I think Laguardia and Newark temperatures during heat waves are the highest around, especially night temperatures. They are open concrete and tarmac and Newark surrounded by chemical and industrial like plants. Kennedy not as bad because of the ocean and smaller airports are not surrounded by as much concrete.

    Are there any chemical plants left in northeast Jersey?  There are no major industrial manufacturers left in Linden NJ, just a few relatively clean power producing plants, except fro the Bayway refinery.  Newark is certainly paved over pretty good, like you said.

  5. DEFINE YOUR WINTER EXPECTATIONS

    As I read through many of the differences and arguments in these threads, it seems there are as many definitions of winter as there are people posting. While I prefer cold and snowy, you can’t expect much more than “normal”.  Please enter your definition of winter in the format below:

     

    Type:  Romanticist  (Note:  Type should reflect if you are a “snow hater”, “snow lover”,  “realist”, “rationalist”, “pessimist”, etc.)

    Temperature:  Near normal – enough for the local ponds to freeze for at least four weeks

    Snow:  Normal, with conditions that don’t allow every snowfall to melt within 2-3 days; sustained

    snow cover.

    Duration:  Mid December through mid March

    Comments:  If winter conditions have not materialized (cold, snow) by mid January, and most long range models don’t see any cold air in place for the next 2-3 weeks, I usually write off winter.  Yes, we could still receive a snowfall or two, and there “can” be an abrupt pattern change, but without winter conditions by mid February, the “Romanticist’s” winter never really was.


  6. Interesting at 7:30PM the NEXRAD radar was showing the precipitation shield "leap-frog" northeast NJ about 50-100 miles northeast.  This would seem that there was an energy transfer just as the storm approached our area?  Quite a tease, as we watched the precipitation move in a uniform manner from West Virginia, and then all of a sudden, skipped over our area.  Then again, precipitation doesn't actually act (or move) as a vehicle driving along a highway.  Rather, the low pressure system is continually propagating itself, as if the low pressure system is actually continually building the road out ahead of the vehicle.

    I don't understand these elementary posts

     

    feb and march ? lol winter started like 16 days ago...

    Meteorological Winter began December 01st and ends February 28th.  The general consensus is that most of January seems lost to receiving much snow, barring a significant change in the persistent Pacific jet and its influence on the overall pattern.  That leaves February...

    Was it supposed to be flurrying this morning? 

    Flurrying here also in Linden NJ (Tremley Pt.).  There was a slight chance of snow showers predicted for last night (but not by the NWS).
