DAYS 1-5 (OCTOBER 16-20)
Discussion…
The second of a one-two rainfall punch this week occurs tonight and early Saturday as a cold front traipsing west to east across the region serves as an avenue for a wave of low pressure which will move swiftly northward along it. Behind this comes a brief shot of chilly air later Saturday as it dries out, but along with some wind as the low organizes while pulling away and high pressure builds toward the region. This high’s center will be close enough by Saturday night and early Sunday to drop the wind off and set up some good radiational cooling, so Sunday morning will be a day that starts cold but ends milder as the high center moves offshore and turns the wind southwest. This milder trend will continue into the start of next week as high pressure will be off the Atlantic Coast with a southerly wind here, and the next cold front approaching from the west will likely run out of gas as there is not much of a push to get it all the way to and beyond the coast.

DAYS 6-10 (OCTOBER 21-25)
A mild southerly air flow and a minimal chance for any rain showers October 21-22 as a couple frontal systems try and likely fail to make it through the region. A stronger front approaches mid period and may bring rain showers and finally a shot of much cooler air for later in the period. Meanwhile, watch for low pressure to organize south of the region by the October 24-25 weekend. Too early to tell if it will bring any rainfall here.
DAYS 11-15 (OCTOBER 26-30)
There is the potential for a second ocean storm (possibly born in the tropics at first) most likely passing east of the region but serving to bring down some colder air from Canada. A system from the west may bring some precipitation to the region around the middle of the period. Many pieces to the puzzle yet to fit together as we get closer to the home stretch of October.
