Area Forecast Discussion

1013 AM EST Thu Jan 27 2022

.SYNOPSIS...

High pressure will move east of the region today. A cold front

will cross the region Friday. Strong low pressure will approach

the Gulf of Maine Saturday, cross Nova Scotia Saturday night,

then exit across the Maritimes Sunday. High pressure will build

over the region Monday.....

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

A cold front crosses the region Friday with mostly cloudy skies

along with a chance of snow showers. Any snow accumulations

Friday should be an inch or less. The cold front exits across

the Gulf of Maine Friday night, while an ocean low intensifies

east of the Mid-Atlantic region. Expect partly cloudy skies

along with a chance of evening snow showers across northern

areas Friday night. Across Downeast areas, expect mostly cloudy

skies with a chance of snow showers early Friday night, then a

chance of steadier snow late. A deepening upper trof, upper

level jet support and phasing of northern and southern stream

energy will allow the low to explosively deepen while lifting

northeast Saturday. A closing upper level low will capture the

surface low later Saturday into Saturday night. Uncertainty

still exists regarding the exact track and intensity of the low.

Snow will expand north across the region from later Friday

night through Saturday afternoon. Heavy snow is possible across

Downeast and east-central portions of the forecast area Saturday

afternoon into Saturday night. High pressure will remain ridged

northwest of Maine Saturday through Saturday night, leading to

lesser snow accumulations across northern and northwest portions

of the forecast area. Strong gusty winds with the low will

produce extensive blowing and drifting snow across the entire

region Saturday afternoon which will persist into Sunday, even

for areas with lesser snow accumulations. Whiteout conditions

are likely at times. Wind gusts up to around 50 mph are possible

Downeast, with gusts in excess of 40 mph possible across

northern areas. Near normal level temperatures are expected

Friday, with below normal level temperatures Saturday.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...

The low will exit across the Maritimes Sunday. Snow will

persist through early Sunday, tapering to snow showers Sunday

afternoon in the wake of the exiting vertically stacked

surface/upper lows. Snow totals through Sunday remain uncertain

at this time and will be dependent on the eventual track and

intensity of the low. However, total snow accumulations of a

foot or more are possible across Downeast and east-central

portions of the forecast area, with lesser totals

northwest across the remainder of the forecast area. High

pressure will cross the region Monday, then begin to move

east Tuesday. High pressure will move east early Wednesday,

with a cold front approaching late. Generally expect mostly

clear/partly cloudy skies Monday through Tuesday, with

increasing clouds Wednesday. Below normal level temperatures

are expected Sunday/Monday. Near normal level temperatures

are expected Tuesday, with above normal level temperatures

Wednesday.....

Special weather statement in effect for:

Queens County P.E.I.

We are monitoring the development of what is expected to be a very intense winter storm that will impact the province on Saturday and into Sunday.

This storm is expected to start as snow on Saturday morning then change to rain late in the day, with the possibility of freezing rain and ice pellets during the transition.

Rain will change back to flurries early Sunday and then taper off later on Sunday.

Additionally, there is potential for storm surge and higher than normal water levels on Saturday afternoon, mainly for the north coast. Strong ice pressure and ice rafting is also possible.

11:32 AM AST Thursday 27 January 2022

Special weather statement in effect for:

Halifax Metro and Halifax County West

We are continuing to monitor the development of a potentially intense winter storm that will impact the province on Saturday and into Sunday.

Snow, high winds and blowing snow are expected to develop on Saturday morning, then change to rain throughout the course of the day. Current forecast guidance indicates that the changeover to rain will begin along the Atlantic coast late in the morning and progress westward throughout the afternoon, with a period of freezing rain and ice pellets expected during the transition. This period of freezing rain could be prolonged in parts of western and northern Nova Scotia.

Rain will change back to flurries early Sunday and then taper off later on Sunday.

Additionally, there is potential for storm surge and rough and pounding surf for the Atlantic coast of mainland Nova Scotia and Cape Breton Island on Saturday afternoon and again early on Sunday.

Forecast details will become more clear as the system approaches.

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.
