DAYS 1-5 (AUGUST 31 – SEPTEMBER 4)
A well-advertised high pressure system sits atop the region at this time and will provide splendid weather for the final day of August and “meteorological summer”, but we know that summer itself is not over here and the weather going forward will prove that point easily before the end of this 5-day period is over. Before that, high pressure shifts offshore but far enough north for an east to southeast wind flow Tuesday into Wednesday, and while a weak upper level trough slides across there will be some cloudiness and the opportunity for a few showers, but no widespread rain. Thursday we will find ourselves in a summery southwesterly flow with higher humidity. A weak cold front moving across the region Thursday night and first thing Friday may bring a shower but the front is likely be a poor precipitation producer, just bringing slightly drier air for Friday, which will still be quite warm.
TODAY: Sunshine, eventually some high clouds too. Highs 70-77. Dew point upper 40s. Wind variable to SE up to 10 MPH.
TONIGHT: Partly cloudy. Lows 51-58. Dew point near 50. Wind E-SE under 10 MPH.
TUESDAY: Variably cloudy. Risk of a few showers. Highs 71-78. Dew point upper 50s. Wind E-SE up to 10 MPH.
TUESDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog. Lows 58-65. Dew point upper 50s. Wind SE 5-15 MPH.
WEDNESDAY: Variably cloudy. Chance of showers. Highs 72-79. Dew point lower 60s. Wind SE-S 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Chance of a shower. Patchy fog. Lows 61-68. Dew point lower 60s. Wind SW under 10 MPH.
THURSDAY: Partly sunny. An isolated shower or thunderstorm mainly west of I-495 late-day. Highs 82-89. Dew point lower to middle 60s. Wind SW 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Scattered showers and possibly a thunderstorm. Patchy fog. Lows 63-70. Dew point lower to middle 60s. Wind SW 5-15 MPH.
FRIDAY: Sunny to partly cloudy. Highs 83-90. Dew point upper 50s. Wind W 5-15 MPH.
DAYS 6-10 (SEPTEMBER 5-9)
Predominant pattern as high pressure aloft off the East Coast. High pressure builds in from the west at the surface September 5 with fair and mild weather but cooler than the previous couple days, then shifts offshore with a warm up September 6 before a cold front approaches with a shower and thunderstorm risk September 7 (Labor Day). High pressure builds in with dry weather to end the period but temperatures averaging above normal.
DAYS 11-15 (SEPTEMBER 10-14)
Overall large scale pattern doesn’t change too much with a warmer than average temperature regime overall and a few, but limited shower chances.
