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 /UNTIL 6 AM FRIDAY MORNING/
Middle level shortwave energy approaches overnight. Moisture advection centered around 700mb will bring increasing clouds overnight. There is some weak lift, but dry subcloud layer will likely prevent anything more than 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 /6 AM FRIDAY MORNING 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 will be weaker, but there should still be gusts 20-25 mph late morning into the afternoon. 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 THURSDAY/
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%.
