DAYS 1-5 (SEPTEMBER 5-9)

The middle day of the Labor Day Weekend will be the “least fair” but also could be much worse. We’ll have a cloud-dominated day as a warm front approaches, but any shower activity will be fairly limited during the day with the better chance of passing shower activity occurring during tonight. Humidity levels come up today and into early Monday but not to oppressive levels, until a cold front, which may kick off a shower or thunderstorm, passes by during the day Monday from west to east across the region. Overall, Labor Day itself will be a fairly nice day with more sun than today. High pressure brings fair weather Tuesday but a warm front which approach later Tuesday with more clouds arriving, putting us into a warmer and more humid air mass into Wednesday when a cold front will approach with the chance of showers and thunderstorms. Another drier air mass is expected to arrive during Thursday behind that system.

TODAY: Mostly cloudy. A shower possible. Highs 70-77. Wind S increasing to 5-15 MPH with higher gusts.

TONIGHT: Variably cloudy. A few showers possible. More humid. Lows 58-65. Wind SW 5-15 MPH.

MONDAY – LABOR DAY: Partly sunny. A shower possible early. A shower or thunderstorm possible in the afternoon. Humid. Highs 73-80. Wind SW 5-15 MPH wit higher gusts, shifting to W.

MONDAY NIGHT: Partly cloudy. Lows 50-57. Wind W 5-15 MPH.

TUESDAY: Sunny start, cloudy finish. Highs 70-77. Wind W up to 10 MPH shifting to S.

TUESDAY NIGHT: Mostly cloudy. Chance of showers. Lows 60-67. Wind S 5-15 MPH.

WEDNESDAY: Variably cloudy. Chance of showers and thunderstorms. Humid. Highs 72-79. Wind SW 10-20 MPH.

WEDNESDAY NIGHT: Variably cloudy. Chance of showers. Patchy fog. Humid. Lows 60-67. Wind SW to W 5-15 MPH.

THURSDAY: Early clouds then mostly sunny. Highs 70-77. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 10-14)

Hurricane Larry expected to be far offshore but as a strong storm will result in large ocean swells, rough surf, and enhanced rip current activity along the coast. West to east upper level air flow pattern expected. Best guess on timing of disturbances is late September 10 to early September 11, and again late September 12 to early September 13. Temperatures will vary but will not stray too far from normal during this period.

DAYS 11-15 (SEPTEMBER 14-18)

Likely to see a continued west-to-east flow pattern with limited shower chances around air mass changes which result in some up and down temperatures but with warmer than normal in control the majority of the time. Having just passed the peak of the hurricane season and with conditions somewhat favorable for additional activity in the western portion of the Atlantic Basin we will continue the need to be vigilant in regard to this.

  1. Thanks TK.

    It figures that Wednesday my day off will be the absolute worst of this week with heat & humidity, and storms. Oh well. Will those be severe?

      1. The severe potential is there pending the ability to destabilize the atmosphere adequately and the timing of the front and any pre-frontal trough that may exist. Not a “hot” day as you have realized. Warm, yes, but nothing this coming week screams too far above or below normal.

        There’s always a chance the timing of this front is different and we get through Wednesday daytime with pretty much nothing. A few pieces of guidance don’t swing the front there here until Thursday morning. That’s a much slower scenario than I was leaning toward just 24 hours ago, but as we know, even our best guidance can struggle with timing of quick-moving disturbances because they don’t “know” initially what to really focus on and if they over-develop or under-develop a single short-wave then it throws the entire model run’s timing off from there on…

  9. Nice dew point jump today all areas into 60s after dry air yesterday. Why doesn’t it “feel” as humid to some? Cool air.
