DAYS 1-5 (NOVEMBER 16-20)
Low pressure accelerates into Atlantic Canada today, intensifying and expanding its circulation. After a round of beneficial rain – that started as sleet in some areas and included thunder in some areas too – we’ll dry out today with increasing wind. It’ll be relatively mild at first, but a colder air mass arriving behind the departing storm system will cause the temperature to fall starting this afternoon, and while we remain in a brisk west to northwest air flow through Tuesday we’ll experience below normal temperatures, but with generally dry weather (only the risk of a brief passing rain shower this afternoon and snow flurry tonight and/or Monday). By Wednesday, high pressure builds in for more tranquil weather conditions. While this is occurring, what’s left of the Greenland Blocking pattern will send one more disturbance to our south and allow high pressure to remain in place through Thursday with continued fair weather.
TODAY: Lots of clouds / intervals of sun. Slight chance of a quick-passing rain shower. Highs 50-57. Wind shifting to W and increasing to 10-20 MPH with gusts 25-35 MPH, strongest over higher elevations.
TONIGHT: Partly cloudy. Slight chance of a brief passing snow flurry. Lows 28-35. Wind W to NW 10-20 MPH, higher gusts.
MONDAY: Partly sunny. Slight chance of a brief passing snow flurry. Highs 38-45. Wind NW 15-25 MPH, higher gusts.
MONDAY NIGHT: Mostly clear. Lows 21-28 except 28-35 immediate coast and urban centers. Wind NW 5-15 MPH, higher gusts.
TUESDAY: Mostly sunny to partly cloudy. Highs 40-47. Wind NW 10-20 MPH, higher gusts.
TUESDAY NIGHT: Clear. Lows 18-25 inland low elevations, 25-32 elsewhere. Wind NW diminishing to under 10 MPH.
WEDNESDAY: Sunny. Highs 46-53. Wind variable up to 10 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 25-32. Wind calm.
THURSDAY: Mostly sunny. Highs 47-54. Wind variable to SW up to 10 MPH.
DAYS 6-10 (NOVEMBER 21-25)
Greenland block is gone and the storm track shifts into one that takes low pressure areas into the Great Lakes, the first of which will do so at the beginning of the period bringing us unsettled weather late next week. Still have to work out timing for a rain threat on November 21 and if there will be any follow-up unsettled weather over the weekend of November 22-23, or if we see 2 more distinctive systems November 21 & 24. Either scenario is possible. I’ll watch trends on this and fine-tune this forecast. Temperatures for this period while typically variable should average slightly above normal.
DAYS 11-15 (NOVEMBER 26-30)
Thanksgiving is November 27. The weather pattern from midweek Thanksgiving week through the holiday weekend will be similar with a leaning to milder than average for the period overall, and 1 or 2 threats of unsettled weather depending on timing of weather systems. Much more to come soon!
