DAYS 1-5 (NOVEMBER 18-22)
Blocking relaxes over the next few days. As mentioned on yesterday’s discussion, we keep the blustery chilly weather today between high pressure to the west and a large storm system in Atlantic Canada, before high pressure builds in with more tranquil conditions Wednesday and Thursday. During later Wednesday and early Thursday, a smaller low pressure area will slide out just south of New England, throwing some of its high and mid level cloudiness into our sky, but its precipitation remaining south of the area. Friday, another low will head through the Great Lakes and down the St. Lawrence Valley, and its cold front can bring us some rain showers at some point during that day – timing to be fine-tuned. This system will push offshore with it now looking more likely that Saturday will be dry with a brisk northwesterly breeze.
TODAY: Mostly sunny to partly cloudy. Highs 40-47. Wind W 10-20 MPH, gusts around 25 MPH.
TONIGHT: Clear. Lows 23-30 except 28-35 coastal areas and urban centers. Wind W 5-15 MPH.
WEDNESDAY: Sun becomes filtered by high clouds at times. Highs 46-53. Wind W 5-15 MPH diminishing and becoming variable under 10 MPH.
WEDNESDAY NIGHT: Variably cloudy. Lows 25-32. Wind calm.
THURSDAY: Clouds limit the sun. Highs 47-54. Wind variable up to 10 MPH.
THURSDAY NIGHT: Partly to mostly cloudy. Lows 33-40. Wind SW 5-15 MPH.
FRIDAY: Mostly cloudy. Chance of rain showers. Highs 47-54. Wind SW 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 31-38. Wind NW 5-15 MPH.
SATURDAY: Sun and passing clouds. Highs 45-52. Wind NW 10-20 MPH.
DAYS 6-10 (NOVEMBER 23-27)
Guidance remains somewhat wishy-washy on deterministic details which are harder to determine out this far anyway. Eyeing November 24 for a potential wet weather event. Other systems to watch: November 26 but should pass south. At the moment, timing leads me to lean toward dry weather for Thanksgiving Day.
DAYS 11-15 (NOVEMBER 28 – DECEMBER 2)
Same mode of thinking. We watch for a larger intrusion of cold air into the US at some point around the end of Thanksgiving Weekend into the first couple days of December, but with a lot of uncertainty as to timing and where the thrust of the cold would be. In our region, I expect a low pressure area to track through the Great Lakes early in the period and sweep a strong cold front through here with at least an initial shot of colder air behind it. After that the leaning is for a seasonable to chilly but dry pattern.
