.SYNOPSIS...

A cold front will cross the area through the day on Friday.

Strong low pressure will track east of the region later Friday

through Saturday. High pressure will cross the region Sunday.

Low pressure will impact the region Monday, though the track is

still uncertain. The low will exit across the Maritimes Tuesday.

&&....

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...

Have issued a Winter Storm Watch for central and coastal

portions of Washington county from Friday afternoon through

late Friday night. Have transitioned the Wind Chill Watch to a

Wind Chill Warning across northern and central portions of the

region from Friday evening into Saturday afternoon. Intense low

pressure tracks east of the Gulf of Maine toward Nova Scotia

Friday night, with high pressure ridged across the northern

Great Lakes. The western edge of the precipitation shield will

reach Washington county Friday night, though snow amounts are

still uncertain. Generally expect snow accumulations across

Washington county to range from 1 to 2 inches across northern

areas, with 3 to 6 inches across central and coastal portions.

However, a more western track would allow for potentially

greater snow accumulations. A more eastern track would lessen

snow accumulations. A sharp gradient of lesser snow totals will

exist west of Washington county. The tight pressure gradient

between the Maritimes low and high pressure to the west will

support strong gusty north/northwest winds which could gust in

excess of 40 mph at times. Regardless of snow totals, expect

blowing and drifting snow to be a concern Friday night into

Saturday. Have issued a Winter Storm Watch for Washington

county from Friday afternoon into Friday night to account for

the variety of potential hazards. The snow will taper to snow

showers then end overnight with decreasing clouds Downeast.

Across northern portions of the forecast area, expect

partly/mostly cloudy skies along with a slight chance of snow

early Friday night with clouds then decreasing overnight. The

gusty winds and very cold temperatures will create dangerous

wind chill values across the region Friday night into Saturday.

Have issued Wind Chill Warnings for northern and central

portions of the forecast area. Wind Chill Advisories will

eventually be needed Downeast. The intense low will lift toward

Newfoundland Saturday, while high pressure builds toward New

England. Gusty north/northwest winds will persist Saturday with

the tight pressure gradient persisting across the region.

Otherwise, expect mostly/partly sunny skies north Saturday with

mostly sunny skies Downeast. Blowing snow could remain a concern

Saturday. High pressure will approach Saturday night with

mostly clear skies. Winds will gradually decrease Saturday

night, though dangerous wind chills will likely remain a

concern. High pressure then crosses the region Sunday with

mostly sunny skies and lighter winds. High temperatures Saturday

will generally range from the single digits below zero north,

to the single digits above zero Downeast. High temperatures

Sunday will generally range from 5 to 10 above zero north, to

the mid to upper teens interior Downeast with upper teens to

around 20 along the Downeast coast.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...

High pressure begins to move east Sunday night while low pressure

intensifies across the Mid-Atlantic region. Expect increasing clouds

Sunday night. Could also have a chance of snow late, mostly

Downeast. The intensifying low will lift north Monday, though

differences in the track still exist. Track solutions still

vary from west of the region, to across the region, to offshore

east of the region. Precipitation types and amounts, along with

temperatures, Monday will be dependent on the eventual track.

However, would lean toward an eventual track either across the

region or closer to the coast. The low exits across the Gulf of

Saint Lawrence Tuesday with high pressure building toward the

region late. Any remaining precipitation should diminish early

Tuesday. A clipper system could bring a chance of snow or snow

showers to the region Wednesday. The system should then exit

across the Maritimes Thursday. Temperatures Monday will be

dependent on the eventual track of low pressure. Expect near

normal level temperatures Tuesday. Expect below normal level

temperatures Wednesday/Thursday.

Freezing rain warning in effect for:

Halifax Metro and Halifax County West

Significant winter storm will give rain, snow and an extended period of ice pellets or freezing rain.

Locations: much of mainland Nova Scotia.

Time span: Friday night until Saturday morning.

Remarks: Rain at times heavy will transition to an extended period of ice pellets or freezing rain Friday night before transitioning to snow Saturday morning.

Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Take extra care when walking or driving in affected areas.

Freezing rain warnings are issued when rain falling in sub-zero temperatures creates ice build-up and icy surfaces.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NSstorm@ec.gc.ca or tweet reports using #NSStorm.

9:44 PM AST Thursday 13 January 2022

Rainfall warning in effect for:

Total rainfall: 30 to 50 mm.

Maximum wind gusts: 70 km/h.

Locations: eastern mainland Nova Scotia and Cape Breton.

Time span: Friday evening until Saturday morning.

Remarks: Rain at times heavy will changeover to an extended period of ice pellets or freezing rain early Saturday morning over eastern mainland Nova Scotia then over Cape Breton Saturday morning. All areas will changeover to snow Saturday morning.

Heavy downpours can cause flash floods and water pooling on roads.

9:43 PM AST Thursday 13 January 2022

Winter storm warning in effect for:

Pictou County

Significant snow, blowing snow, freezing precipitation and wind is expected.

Total snowfall: 20 cm to 40 cm, locally higher over higher terrain.

Maximum wind gusts: 80 to 100 km/h.

Locations: western and northern Nova Scotia.

Time span: Friday evening until Saturday morning.

Remarks: Periods of rain Friday afternoon will transition to snow at times heavy and will likely mix with ice pellets before midnight. Strong northerly winds in conjunction with the fresh snowfall will result in poor visibility in blowing snow, and may cause utility outages and road closures. Temperatures will drop significantly by Saturday morning in strong northerly winds causing significant wind chill values. Conditions will improve from west to east on Saturday.

Consider postponing non-essential travel until conditions improve. Utility outages may occur. Poor weather conditions may contribute to transportation delays.

Winter storm warnings are issued when multiple types of severe winter weather are expected to occur together.
