SYNOPSIS
High pressure will be in control through early next week with only a weak cold front or trough shifting through during Saturday night into Sunday. A weakening low pressure system then passes nearby for Monday night into Tuesday. A stronger system moving through southeastern Canada then sends a cold front across the local area Wednesday into Wednesday night.
NEAR TERM /THROUGH TONIGHT/
Little in the way of clouds through at least the evening hours before moisture advection centered around 700mb pushes in from the west and increases cloud cover. Some shortwave lift in the mid levels will be present as well, so maybe some flurries late at night. Anticipating temperatures to become more steady late tonight after falling into teens to mid 20s. Winds diminish through the period, backing to the west, but wind chills still drop to 5 to 15 above.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
Key Point:
* Mainly dry through the period, but with below normal temperatures.
Weak high pressure will be in place during the period, and this will keep us dry through the day Saturday. Temperatures will however remain around 10 degrees below normal. Winds won't be as much of a factor as they will be this evening, but wind chills still drop to 5 to 15 above once again on Friday night, with chills averaging closer to 20 Saturday night.
As for Saturday night, a weak cold front or surface trough along with cyclonic flow aloft are progged to move into the region, which may bring snow showers to the area late at night. Not expecting much, if any accumulation, so no impacts anticipated.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Key Points:
* Moderating temperatures for the mid-week period.
* Conditions potentially meeting advisory or warning criteria are not expected.
Only minor changes made to NBM for the long term. A weak system brings a 20-30% chance of light snow Monday night. A stronger system tracking across southeastern Canada then sends a cold front through the area Wednesday into Wednesday night with a better chance of precipitation, which would be rain showers. Precip chances are still however below 50%.
OUTLOOK FOR 18Z FRIDAY THROUGH TUESDAY
Friday: VFR. W winds G15-20kt.
Saturday - Monday: Mainly VFR.
Tuesday: Mainly VFR with MVFR or lower possible in showers.

MARINE
Winds diminish through tonight, but gales should still be occurring on the ocean waters through the rest of the day into early evening. Even occasional gale force gusts are anticipated on the other local waters this afternoon. SCA on most of the non-ocean waters continues through 10pm tonight as advisory conditions will prevail during the period. After the Gale Warning is set to expire early this evening on the ocean waters, SCAs will be needed tonight through at least a part of Friday night due to winds and/or seas. Sub- advisory conditions then prevail on all waters from Saturday through the rest of the forecast period.
