Friday October 9 2020 Forecast (7:32AM)

DAYS 1-5 (OCTOBER 9-13)

Discussion…

After some areas saw a frost this morning, another seasonably cool October day is in store today, but this one will come without the wind of yesterday as we are in a weaker gradient on the northeast side of a high pressure area, but that gradient will tighten up again Saturday as the high slips off to the south, remains rather strong, and is pressed by low pressure passing to the north. If you are out and about tonight, especially late, you may notice that the coolest part of the dark hours occur just prior to midnight, and that the wind picks up a little and it feels a little less cool as we approach dawn. Along with the increase in wind again Saturday will come a big temperature jump, and it will remind you a little of the summer days of not so long ago, other than our sun angle is now much lower. It’s interesting to note that if the lowest potential temperature tonight is reached, these areas could have about a 40 degree diurnal (spread from lowest to highest temperature) from Saturday’s very early morning hours to its early afternoon hours. A cold front will move from north to south across the region Saturday night and other than a slight chance of a few passing showers, it will just bring mainly clouds with it as it turns our wind to the northeast by early Sunday, which will turn out to be much cooler. While most of the clouds associated with the front will move out early Sunday, we’ll probably have filtered sunshine for a good portion of the day as the high cloud shield from what will be the remains of Hurricane Delta (currently in the Gulf of Mexico) spreads across the sky here. The meteorological conundrum in my head the last few days has been whether or not we get into the rain from the remains of that systems, and if so, trying to determine its significance. Yes, I do believe we will get into it, somewhat, but that it probably holds off until late Monday or even Monday night and into Tuesday. At this point, I am reluctant to say we’ll have a regional beneficial rain to help our drought situation, but any rain, so long as it’s not coming too fast and furious, will help. So I’ll continue to monitor this and fine-tune the rain chances as we get closer to the event. Also, please see the comments section below for some information sent by a long time colleague which refers to hurricane landfalls. It may surprise you.

DAYS 6-10 (OCTOBER 14-18)

Low to moderate confidence outlook for a west to east flow overall but mean trough position Great Lakes to Northeast with a cooler regime, but mostly dry weather.

  1. From a long time colleague and respected forecaster (who prefers to remain anonymous)..
    They’ve given me permission to share their frequent statistical and factual messages, and here is the most recent one, prompted by a flood of social media comments about how rare it is for the same state to get two hurricanes in one state in one season.

    “All this hype about the same spot in LA getting hit twice
    in once season by a hur. It is *not* unusual, and it
    was a lot more common in the late 19th century to the mid 20th.
    Not as common since. Multiple landfalls in the same state
    as well occurred more often then. 2 hur landfalls in the
    same state in one season hasn’t happened in 12 years.
    Proof by verbosity below? Yes, but these are hard facts
    and gives all the data in the last 160 years as to frequency.”

    3 hurrs made landfall in LA in 1860, 2 in the same spot.

  2. Thanks, TK…

    34 here on the ye ole Oregon Scientific
    31 down in the bogs of the East Taunton airport
    30 at 6 am at the Norwood airport

    1. Resisting urge to turn on heat briefly. We had left a couple windows open a bit last night. Thermometer in center of the house was 59F a few hours ago and am guessing a little cooler in the north side of the house. Meanwhile, the rooms facing east and south are warmer for sure.

  3. Last week I posted what I believe to be the strongest winds in storms in my lifetime.

    December 9, 2005 came to mind. I found the report on that snowstorm. NWS/BOX noted:

    105 mph on Block Island (public)
    101 mph Wellfleet (public)
    100 mph Orleans (public)
    96 mph Eastham (amateur radio) before anemometer was knocked down by a falling tree
    94 mph Nantucket Harbor
    81 mph Taunton (measured by a NWS employee)
    73 mph Manomet (NWS spotter)

  4. Was looking at the current ENSO this morning …….

    Looks like early in the year, we started with a neutral to slightly positive ENSO, have trended to a LA Nina condition and projecting out, the projection is for ENSO to trned back to neutral, if not slightly positive next spring.

    Looking at the history of El Nino, LA Nina, I would suggest that 2005-2006 had a similar ENSO pattern.

    1. I’m going to have to take a look at my notes later to see how much snowfall for Logan during that 2005-06 season. Off the top of my head, I don’t think it was above normal, or even close to normal for that matter.

          1. 2005-06 was below normal at Logan, but not by much. Considerably better than I thought.

            39.9” (43.8” normal)

            1. Of course a projected ENSO that is somewhat similar to that winter doesn’t really mean that we’re in for a winter like that one. There are only about a dozen other factors to take into account, some of which will be unknown for about 6 more weeks.

  5. Here’s an issue with having 2 vastly different weather sources on one media outlet. WBZ radio this morning played an AccuWeather teaser which indicated rain late Sunday into Monday from the remains of Delta, immediately followed by a forecast from Eric Fisher that stated the chance of rain was later Monday into Tuesday. Oops.

    FTR, I’d go with Eric’s forecast on that one.

  6. Looks like Delta might have come ashore with a pressure around 970 mb.

    Quite a rain shield to its north. Hopefully, the weakening state will have the right front quadrant areas experiencing a strong tropical strong with some occasional hurricane force wind gusts.

    WIll be interested to see what the rainfall totals end up.

  7. Models will have to back off a bit on the rainfall totals for up here for them to be in the correct ballpark.

      1. The ones I looked at during the course of yesterday were in the 1-2 inch category for the most part.

  8. A nice shiny new weather post has been written with great care just for you. Feel free to ignore it and just go right to the comments. 😉
