DAYS 1-5 (SEPTEMBER 20-24)<\/p>\n\n\n\n
The next 3 days (through Friday) will be dominated by high pressure with fair weather with mild days and cool nights. Late in the week we’ll be watching the development of a low pressure area near the US Southeast Coast. Most guidance tries to push this low somewhat to the north over the weekend, but takes its rain shield more vigorously north, now early enough to arrive sometime on Saturday. But that’s not necessarily my forecast just yet. I’ve seen a very similar set-up be handled incorrectly by medium range guidance before, with the computer simulation taking the rain shield too quickly and too solidly north, when in reality the high pressure area holds stronger and dry air associated with it gives the rain area a buzz cut, and a deflection. I’m leaning toward this scenario at the moment, which if it is the case, we’ll salvage Saturday mainly dry around the region, despite increased cloud cover, and then Sunday would be the day with a higher rain chance as the low pressure area, now weakening, got closer to the region. Fine-tuning of this outlook will take place as needed through the week. One thing that is not uncertain – fall arrives at 2:50 a.m. Saturday with the occurrence of the autumnal equinox.<\/p>\n\n\n\n

THURSDAY NIGHT: Mostly clear. Ground fog patches low elevations. Lows 48-55. Wind variable under 10 MPH.<\/p>\n\n\n\n
FRIDAY: Mostly sunny. Highs 67-74, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.<\/p>\n\n\n\n
FRIDAY NIGHT: High clouds increase. Ground fog patches low elevations. Lows 48-55. Wind calm.<\/p>\n\n\n\n
SATURDAY: High overcast, may thicken up enough for some rain near the South Coast or Cape Cod. Highs 66-73. Wind E 5-15 MPH.<\/p>\n\n\n\n

DAYS 6-10 (SEPTEMBER 25-29)<\/p>\n\n\n\n
If my scenario works out as expected, high pressure to the north pushes surface low pressure to the southeast of our area but an upper low means lots of clouds and maybe a few showers around on September 25 before the high pressure area takes over with another stretch of dry weather. Temperatures would cool down early period and warm up again later.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 30 \u2013 OCTOBER 4)<\/p>\n\n\n\n
Guidance is divergent out this far, but the general pattern to me looks weak hybrid – a bit of a zonal (west to east) flow over our region but still a tendency to see high pressure to the north of the region and low pressure to the south of the region, which can always set up potential battle zones. Leaning toward a drier pattern with no major temperatures swings to end September and begin October.<\/p>\n","protected":false},"excerpt":{"rendered":"
