Beautiful Weather Arrives in Alberta and British Columbia

Temperatures soar above freezing today in the Rockies and Foothills – including Banff, Jasper and Calgary. Double-digit highs for Lower Mainland and Southern Interior British Columbia today and Tuesday. Dense fog this morning in Southeast Alberta degrades to abundant sunshine.

A broad area of high pressure combined with plentiful sunshine, and light changeable winds, will send temperatures soaring above freezing today and Tuesday across Southern British Columbia and Southern Alberta.

Overnight-lows in Calgary, Red Deer, Airdrie, Lethbridge, Medicine Hat – and much of Southern Alberta were close to or below negative 10c. The same locales today will be in the upper single digits. The warm above seasonal weather will persist into Tuesday. Temperatures will (once again) fall well below freezing tonight, quickly rising into the upper single digits Tuesday Afternoon. Pleasant temperatures are expected to persist for much of the week.

Much of the same conditions is expected for Southern British Columbia. Locales in the Lower Mainland – including Abbotsford can expect highs in the teens today.

[UPDATED] Unsettled Pattern Arrives in Eastern Canada

Unsettled week ahead for the Maritimes to Ontario, including Quebec.

A formidable late winter snow storm has dropped impressive snowfall totals across parts of the Canadian Prairies in recent days. The same storm system has weakened and stalled over the Great Lakes, while aiding in the formation of a new surface low that tracked into the Maritimes.

The newly-formed system tracked up the Eastern Seaboard concurrently as a trough sits over the Great Lakes, becoming a weather maker for much of Eastern Canada.

ONTARIO

Predominantly cloudy conditions, with periods of flurries and wet snow continues Thursday and Friday across Southern and Northeastern Ontario. Trace amounts are expected for most, but parts of Southwest Ontario and Eastern Ontario could see several day totals approach 10-20cm. Actual ground accumulation will be less considering melting and settling.

—-

A more substantial in addition to localized snowfall threat will develop Wednesday morning, spanning parts of southwest Ontario. As a result of moisture enhancement off of the Great Lakes and a stalled trough over the region. A few wet centimetres is likely to accumulate east of Lake Huron. The unsettled pattern continues into Wednesday, Thursday and perhaps Friday. 5-15 centimetres of accumulation spanning the work week is expected. Highest totals away from the lakeshore and in regions of higher elevation.

MARITIMES

A moisture-laden system approaching the Bay of Fundy will continue to spread snow and rain across the Maritimes. Moderate snowfall continues to impact central Nova Scotia, PEI and New Brunswick. An additional 3-8cm of wet snow is expected to accumulate today, before this low tracks north. Precipitation will likely end as rain showers as temperatures warm. The heaviest totals from this system will be across a swath of central New Brunswick where 15-20cm is expected.

A second powerful storm system is expected to develop Friday lasting into Sunday. Strong winds gusting 50-70km/h and heavy snowfall amounting to an additional 10-25cm will be a concern.

Snow is expected to begin across Nova Scotia and PEI, transitioning to rain as the warm sector of the storm continues north throughout the day Thursday. Highest accumulations are expected in Cape Breton. Elsewhere, several wet centimetres will fall before a changeover to rainfall. There is still some uncertainties in exact track of this system(s). Once forecast confident increases, we will publish a region specific forecast for the maritimes promptly.

Primarily snowfall is expected in central and northern New Brunswick, with a changeover to rainfall near the Bay of Fundy.

QUEBEC

Flurries and light snowfall continue in Southwestern Quebec. A retrograding coastal low moving west-wards towards the Saint Lawrence river Thursday into Friday morning, will being heavier snow to Southeast Quebec and the Eastern Townships. Total accumulations are expected to be in the 10-20cm range by Friday evening.

Nova Scotia

Powerful Winds; Fierce Waves for Southern Nova Scotia

A broad area of low pressure is forecast to coalesce into a powerful coastal low through Friday. A new low pressure center will develop near Cape Cod this morning, intensifying into an expansive coastal wind storm.

Strong north-easterly winds will intensify throughout Friday.

Along the Atlantic coastline adjoining Queens to Shelburne county, wind gusts ranging between 90-100 km/h are expected by Friday evening. Elsewhere, along the coast from Halifax to Yarmouth, peak wind gusts of 80 to 90km/h are expected. Winds should diminish through the day Saturday, as the low translates south-east.

At this point in time, it appears any heavy rainfall associated with this system will remain off shore.

Pounding surf, fierce waves & higher than usual water

Coastal communities expanding across Southern Nova Scotia from Halifax to Yarmouth (including Lunenburg), can expect wave heights between 5 and 6 meters Friday and Saturday. On Saturday morning, high waves and pounding surf are forecast to creep north – encompassing the remainder of the eastern Nova Scotia coastline. Higher than usual water levels are expected to coincide with high tide both Friday and Saturday, raising coastal flood concerns.

Environment Canada Issues Wind Warnings and Special Weather Statements ahead of the storm.

The weather agency noted on Thursday that “astronomical high tides will be running high during this period of elevated water levels adding to a risk of coastal flooding”.

Above Seasonal and Abundant Sunshine for Southern Ontario


An area of high pressure south of the border is expected to move eastwards on Monday and cement its presence until Wednesday, thereby keeping tempestuous weather at bay.

Beginning Monday, February 26th, abundant sunshine is expected to spread and flourish across the entire region giving residents a “taste” of spring weather.

While temperatures on Monday are expected to reach the upper single-digits, on Tuesday and Wednesday, residents can welcome temperatures into the low-teens. On the contrary, temperatures will be sliced in half on Thursday and thereafter for the foreseeable future.

High Temperatures for Southern Ontario on Monday.

High Temperatures for Southern Ontario on Tuesday [and Wednesday].

This short period of above seasonal temperatures are expected to cause further concern regarding relevant regions impacted by flooding. It is important to remain diligent and refrain from close presence near high rivers and fast-moving waters.

Now, get outside and lets welcome these temperatures together!

Ontario

Evacuation Ordered for Brantford, ON

A parade of weather systems in combination with several factors, including record warmth, frozen ground/snowmelt, and ice-jams, have led to flooding along riverside watersheds across Southern Ontario.

The City of Brantford has been hit especially hard this morning, where a State of Emergency has been issued.

Evacuation Order

City officials have issued Evacuation Orders for any street identified in the following floodplain: Foster, Cayuga, Aberdeen, Strathcona, Pontiac, Tecumseh, Ontario, Port, Eagle Ave, Robertson, Dover and Baldwin.

Residents are urged to evacuate these areas of the city until water levels recede and the Evacuation Order is lifted.

High Water Levels Across Much Of Southern Ontario

All communities along river-side watersheds and their tributaries throughout Southern Ontario, are urged to monitor local watches, warnings and statements from their local Conservation Authority. Flood warnings remain in affect for many watersheds who are dealing with flood conditions.

The flood concern is expected to peak early this afternoon (Wednesday), when cooler temperatures and drier air arrives. A brief period of freezing rain north of the GTA, will make efforts challenging for cleanup crews who are working tirelessly pumping water to ease residential flooding.

What Caused The Flooding?

A persistent High pressure ridge off the coast of Bermuda is responsible for channeling Gulf moisture and record warmth that led to this early “spring like” flooding event across Southern Ontario.

Canadian Coast Guard Dispatched Amid Flood Concerns

Canadian Coast Guard vessel Griffon has been dispatched to Lake Erie and the mouth of the Grand River amid flooding concerns.

The CCGS Griffon will be breaking up ice jams near Port Maitland, ON and the mouth of the Grand River today, where is connects to Lake Erie. This is an effort to reduce flood risk due to ice restriction of water as it passes down stream today through Wednesday.

Communities along the Grand River and its tributaries should pay close attention to local statements and updated warnings from the Conservation Authority. A flood warning remains in effect for the entire watershed.

The flood concern is expected to peak Wednesday morning, before cooler temperatures and mixed precipitation arrives.

Total rainfall amounts of 40-60mm is expected. Locally higher amounts are expected east of Lake Huron.
