Here We Go Again: Another Nor’easter

Another Nor’easter Targets the Maritimes Thursday; Late Thursday through Friday for Newfoundland.

A relentless parade of Nor’easters continue to track into the aforementioned regions. While amounts will not be entirely substantial due to slightly warmer surface and upper atmospheric temperatures, amounts will still threaten commute and travel times.

The low pressure system will approach from the southwest bringing alongside a widespread swath of snow, however, transitions to rain/wet snow and/or ice pellets will encompass much of the shoreline of Nova Scotia, thereby likely limiting snow.

The heaviest snowfall accumulations will reside in SE New Brunswick and NW Nova Scotia, and PEI, through Thursday; for Newfoundland, the heaviest snow will reside in western sections.

Depending on the exact [and final] track of the Nor’easter, amounts may vary from the listed depictions +/- 5cm.

Please stay tuned, as we at TCW are monitoring this situation attentively.

Drive safe and always be alert during winter conditions.

Powerful Nor’easter Looms for the Maritimes; Tempestuous Conditions Inevitable


Past Updates

Nor’easter for the Maritimes.

Significant snowstorm will impact the Maritimes once again: Tuesday and Wednesday time-frame.

A low pressure system moving near the Eastern Seaboard of the United States will target the Maritimes this upcoming work-week. Current indications are now such that a significant snowstorm is probable, particularly for much of New Brunswick and especially the NE corridor of the province.

High confidence exists that this storm will produce a widespread swath of 20-30cm+ across New Brunswick, with slightly lesser amounts along the Bay of Fundy shoreline. Additionally, due to a surge of milder Atlantic air, a mix of snow/rain will lead to less significant amounts for coastal regions of Nova Scotia, Eastern PEI and most of Cape Breton.

While temperatures will be slightly mild at the surface and @ 925mb, further upper atmospheric temperatures are still quite chilly, therefore there is almost a nil chance of freezing rain/ice-pellets.

Subsequently, ‘dry air’ is non-existent in this case at the surface, and moisture will indeed remain high.

Snow ratios will not be exceptionally high, however, based on the current track of the low pressure system, surface temperatures will remain slightly cooler across Eastern and Northeastern New Brunswick, thereby allowing for higher totals than their surrounding counterparts.

Watch for gusty winds/localized blowing snow for Eastern and Northeastern sections of New Brunswick up to 75km/h. Elsewhere, gusts up to 65km/h is probable.

While snow will be somewhat limited, watch for very strong wind gusts for Nova Scotia near the coast up to 110km/h.

Updated Information: March 13th, 2018 @ 7:00PM ADT

Nor’easter continues to loom for much of the Maritime provinces. High confidence still exists for a significant impact.

Current indications support particularly major impact for Eastern and Northeastern sections (especially) of New Brunswick where 30-40cm of snow could accumulate.

The track of the low will now move more-so slightly off-shore, rather than ‘hug’ the Eastern Seaboard of the USA, thereby allowing for further intensification; milder air will infiltrate the immediate Nova Scotia coast-line, thereby limiting snowfall amounts.

There is some level of confidence that regions along the Greenwood-Kentville (NS) corridor could now receive 15-20cm instead of the 8-15cm as previously posted. However, because confidence is not entirely high we have decided to only inform individuals, rather than updating our map.

Highest confidence continues to exist for NE New Brunswick receiving the highest impact from this system (particularly just N and NW of Moncton, through Bathurst).

Heavy snow will somewhat blanket coastal regions of Nova Scotia initially, however, it is important to note that a transition to rain will occur. While snowfall may total 10-15cm across coastal regions of Nova Scotia, it will melt quickly through the Pre-Dawn and the morning of Wednesday (March 14th).

Continue to return to this post every hour as updated information will be released as the event draws near.

Please stay tuned, as we at TCW are monitoring this situation attentively.

[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.

Treacherous Conditions for Quebec and New Brunswick

Respectable ice accretion is expected to build for parts of Quebec and West-Central regions of New Brunswick.

Freezing rain is expected to creep through both of the aforementioned provinces and pose an extended threat of widespread freezing rain. While not all regions are expected to be targeted, regions such as Quebec City and its Northern suburbs, as well as, regions in West-Central New Brunswick will become treacherous as upwards of 15mm of accretion could result. Regions elsewhere will receive minimal accretion, and thereby, only isolated and patchy icy conditions will be present.

Freezing rain is expected to linger into much of the day on Tuesday.

Predominantly rain will target Southern New Brunswick, and Eastern PEI.
