DAYS 1-5 (SEPTEMBER 19-23)

A cold front passes by today with nothing more than a few clouds (no rain). Increased winds and lower dew points lead to elevated fire danger as well. Use caution with anything involving outdoor open flames or sparks, especially around drier brush. High pressure builds into the region tonight through Saturday with a much cooler air mass but less wind with time. High pressure settles overhead Saturday night – a perfect night for radiational cooling with some areas going below 40 for the first time in a long time and even a chance of a few patches of frost in the lowest elevations. The high pressure area keeps us fair Sunday into early next week – still cool Sunday, then an early week warm-up. By late Tuesday, clouds increase ahead of the next trough and frontal system, but as it stands now, any shower threat may be minimal and hold off until Tuesday night. Autumn begins at 2:19 p.m. EDT Monday with the occurrence of the equinox.

TODAY: Sun and passing clouds. Highs 75-82. Wind SW 5-15 MPH, shifting to NW, with gusts 20-25 MPH.

TONIGHT: Clear. Lows 47-54. Wind NW 5-15 MPH.

SATURDAY: Mostly sunny. Highs 63-70. Wind N 5-15 MPH, diminishing late.

SATURDAY NIGHT: Clear. Lows 38-45 inland low elevations, 45-52 elsewhere – mildest in urban centers. Wind calm.

SUNDAY: Mostly sunny. Highs 65-72. Wind variable to S up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Patchy fog. Lows 50-57. Wind S up to 10 MPH.

MONDAY: Mostly sunny to partly cloudy. Highs 72-79. Wind S 5-15 MPH.

MONDAY NIGHT: Mostly clear. Patchy fog. Lows 53-60. Wind S up to 10 MPH.

TUESDAY: Partly sunny. Highs 70-77 South Coast, 77-84 elsewhere. Wind S 5-15 MPH.

DAYS 6-10 (SEPTEMBER 24-28)

A trough and frontal system brings a chance of showers on September 24. Cooler/drier weather follows, but watching another trough for a shower threat at some point during the September 27-28 weekend (low confidence).

DAYS 11-15 (SEPTEMBER 29 – OCTOBER 3)

Overall pattern looks dry with variable temperatures – no extremes heading through the last couple days of September into the first few days of October.

    1. Nice!!! I had 2 legitimate words for guesses 3 and 4, just not the correct word which didn’t come until guess 5. 🙂 Oh well.

  14. In spite of the weather run since August 18th, the central and southern Atlantic are still very warm and plenty capable of making us quite humid.

    Some hints in the medium range on the models of a period of southwest flow aloft and a couple 2 or 3 days of moderate to high humidity in southern New England.

    2. High dew points will be around Sep 24 & for a day or 2 around Sep 27 in response to south and southwest winds ahead of approaching fronts / troughs. But this type of high dew point air has little effect in comparison to the same thing in mid summer. So the impact will be … meh.

    …ELEVATED RISK FOR FIRE SPREAD FRIDAY AFTERNOON…

    Northwest winds with gusts 20-25 mph combined with minimum relative humidity values between 38 to 45 percent, a prolonged period of dry weather, and dry fuels will result in elevated fire weather conditions Friday afternoon.

    Exercise caution handling any potential ignition sources, including machinery, cigarettes, and matches. Any fires that ignite will have potential to spread quickly.

    This forecast considers meteorological, fuel, and land conditions and has been developed in coordination with state fire and land management officials.

  16. On this date in 1928, our area had a humid southerly wind and showers far to the east of the remains of a hurricane that devastated parts of the Caribbean through Florida.

    Unofficially named Hurricane Okeechobee, the storm is the only one to make landfall in Puerto Rico as a category 5 storm (160 MPH).

    Guadeloupe experienced the first landfall (CAT 4) on September 12, followed by P.R.’s pounding a day later. Over the next couple days it raked the Turks & Caicos Islands and the Bahamas, maintaining CAT 4 intensity through landfall at West Palm Beach FL on September 17. As a CAT 3, the storm passed over Lake Okeechobee, triggering a massive dike failure and resulting in flooding that killed over 2000 people. The storm weakened to a CAT 1, curving out by the GA coast, then making a landfall in SC before moving northward and weakening to a TS and further from there.

    The final death toll topped 4100. To this day it is Florida’s deadliest natural disaster.

      1. Yep. Of course they don’t. 😉

        To be clearer: Media doesn’t. Some of our local meteorologists will bring up historical events such as this, but again they are often “contained” by the higher-ups to stick with the “hot topics”, which as you very well know I think is a shame. They would already talk about what’s relevant, but are now limited in adding interesting content.

  17. Update shortly! Was out walking and stopped to say hi to a neighbor setting up a yard sale. Great weather for those!
