DAYS 1-5 (NOVEMBER 24-28)<\/p>\n\n\n\n
Discussion\u2026<\/p>\n\n\n\n
On we roll toward the end of November, with Thanksgiving just 2 days away. Today will be the coldest day of this week as high pressure in the Great Lakes delivers an air mass right out of Canada, air that crossed over snow covered ground on its way here. You’ll feel that chill in the air, minus the snow, but with a gusty breeze today. High pressure will slide eastward, its center passing to our north, tonight into early Wednesday. As a warm front approaches Wednesday, we’ll see clouds move in. As previously noted, this warm front is going to be in for a struggle to make much progress into New England Wednesday night into Thursday (Thanksgiving Day) as low pressure moves slowly eastward into the region. While the actual low center will be weakening, its center, or what’s left of it, will move along the frontal boundary, which by the time it gets into the area will become generally stationary. This means that the warm air probably gets into the South Coast and maybe as far north as I-90 but not much further. This sets up the issue of possible icing in north central MA and interior southern NH if precipitation comes in early enough Wednesday evening, and also sets up an interesting temperature forecast for both Wednesday night and Thursday. Thanksgiving Day itself is likely to be overcast through the day, and see periods of rain, especially during the morning and midday hours. Once we get to Thursday night and Friday, the wind will turn more to the north and eventually northwest, and we will dry out as clouds break, but there is still the risk of a passing rain shower as a disturbance crosses the region on Friday. Even Saturday, which looks mainly dry and milder will have the chance of a passing shower as a front passes through later in the day or during the evening.<\/p>\n\n\n\n

DAYS 6-10 (NOVEMBER 29 \u2013 DECEMBER 3)<\/p>\n\n\n\n
I don’t know. Just kidding – killing a bad joke. Working out the timing and looks like high pressure brings a nice day for November 29 to end “Thanksgiving Weekend” before low pressure comes at us from the southwest and brings a beneficial rain event for the last day of November. There remains some uncertainty in how the first few days of December play out with guidance again all over the place. My current thought is that we may need to watch for a low pressure wave to bring additional unsettled weather at the same time we watch the approach of cold air December 1. Dry\/colder weather follows that.<\/p>\n\n\n\n
DAYS 11-15 (DECEMBER 4-8)<\/p>\n\n\n\n
Hints of of what may be some high latitude blocking trying to set up at some point during this period. This would increase the chance of some East Coast storminess while we’re in the battle zone of warm air to the south and east and much colder air to the west and north. Far too soon for details, other than I’m most concerned with the December 6-8 period.<\/p>\n","protected":false},"excerpt":{"rendered":"
