Texas Low: Severe Outbreak Precedes Potent Storm for Eastern…

A significant trough crossing the Guadelupe Mountains will drive the development of a potent area of low-pressure across Texas Saturday. Favorable conditions for the development of severe thunderstorms, will exist along the warm front axis; ahead of a vigorous cold front. This will be significant “severe weather event” for Northern Louisiana, Southern Arkansas, Western Mississippi, and Eastern Texas. Reloading for a second day of severe weather, across the Eastern United States.

Moisture laden low developing in Texas bringing severe thunderstorms. With impacts across Eastern Canada to end the week. Persisting into early next week.

During the day Sunday, the low is forecast to take a northeast hook towards the lower Great Lakes bringing a plume of rain and snow for Southern/Central Ontario & Southern Quebec.

Atlantic Canada is poised to see the most tempestuous conditions, with rapid deepening of the low-pressure center late Monday. This system will be a heavy-rain story for the Maritimes. On the contrary, Newfoundland could see heavy snow, significant freezing rain and strong winds.

COOL, WET & LOUSY COUPLE DAYS FOR SOUTHERN ONTARIO

Get out and enjoy the abundant sunshine and warm temperatures Saturday. A messy, moisture-laden system out of Texas will deliver below seasonal temperatures, a soaking rainfall, mixed precipitation and accumulating wet snow. The heaviest rainfall will be situated along the Lake Ontario shoreline into the Niagara Region. The heaviest of the snowfall will be seen across parts of Central Ontario – through cottage country.

A lousy system for the Great Lakes. Below seasonal temperatures, a soaking rainfall and more snow expected.

SIGNIFICANT RAINFALL & GUSTY WINDS FOR THE MARITIMES

Significant rainfall will encompass much of Nova Scotia, the Bay of Fundy region in New Brunswick & Prince Edward Island. There is still considerable uncertainty how this low will develop in the Maritimes. Current projections have most of the precipitation falling as rainfall. As much as, 40-75mm of rain is possible, between Sunday night through Tuesday morning.

POTENTIAL ‘WEATHERBOMB’ FOR NEWFOUNDLAND

The system is expected to undergo rapid deepening Monday night. Slowing as it transverses through Gulf of St. Lawrence. A strengthening wind field along the Northwestern coast, persists all-day Tuesday. Refinements to the forecast will come throughout the coming days. Nevertheless, this is looking like a potent system for Newfoundland.

We are becoming increasingly concerned regarding a freezing rain threat for the north coast of Newfoundland. Including Fogo Island, Bonavista North & Green Bay. 10-15mm+ of freezing rain, ending as snow and strong winds could bring localized power outages.

Heavy snowfall will be the story across Northwestern Newfoundland with as much as 20-40cm falling over the hardest hit areas. Concurrent, with strong winds leading to blowing and drifting snow.

Bomb Cyclone Threatens Damaging Windstorm, Snow & Heavy Rain…

A weatherbomb is rapidly strengthening Tuesday off Cape Hatteras, North Carolina. Bringing hurricane-force winds, significant rain & lighting just off-shore. This system will undergo bombogenesis as it tracks up the Eastern Seaboard, through the Gulf of St. Lawrence into Labrador. 

Significant rainfall & snowfall accompanied by damaging winds gusting over 100km/h is anticipated. The most tempestuous conditions being felt across the Maritimes Wednesday afternoon & evening. For Newfoundland & Labrador conditions deteriorate rapidly overnight Wednesday. Persisting through most of the day Thursday.

DAMAGING WIND THREAT

Damaging winds will be the main story with this powerful storm. Atmospheric pressure is expected to drop 28mb within 24 hours. An expansive – strengthening wind field will result. Hurricane-force winds (gusts over 120km/h) expected along the Western coast of Newfoundland & Cape Breton Island.

Les Suetes winds gusting up 160 km/h are forecast to develop Wednesday afternoon, shifting southwesterly before dissipating. Wreckhouse winds could peak between 160-180km/h.

SIGNIFICANT WIND DRIVEN RAINFALL FOR COASTAL NOVA SCOTIA

Environment Canada has issued a Rainfall warning across Nova Scotia. The agency is warning up to 70mm of rain could fall, in the hardest hit regions along coastal Nova Scotia.

Rain at times heavy will develop early Wednesday morning over southwestern Nova Scotia and quickly spread to the remainder of the province by Wednesday afternoon. The rain will be mixed with snow to start over parts of mainland Nova Scotia Wednesday morning. Over Cape Breton, the rain will likely be preceded by a period of snow over some areas.

Rainfall amounts will be highest over Atlantic coastal regions of mainland Nova Scotia where 50 to 70 millimetres are forecast. Elsewhere, 25 to 40 millimetres of rain is expected.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

SNOWFALL ACROSS NEW BRUNSWICK & BLIZZARD CONDITIONS ACROSS LABRADOR

Environment Canada has issued several warning across New Brunswick. This is what they wrote in their statement. Snow will begin Wednesday morning over southwestern New Brunswick and then spread quickly across the province by noon. The snow will likely mix with rain in the afternoon. Snowfall amounts of up to 10 cm are possible. Over eastern regions of the province, snowfall amounts in excess of 15 cm are likely and snowfall warnings are in effect there. Along the Fundy coast, rainfall amounts near 25 mm are possible and rainfall warnings are in effect there. Northwestern New Brunswick will only receive light amounts of precipitation from this system.

Western Newfoundland will have to contend with sea-effect snow and blizzard-like conditions through the day Thursday. 5-15cm of accumulation is expected by Thursday evening. Heavy flurries and snowsqualls may continue Thursday overnight and Friday.

This will be a major winter storm for Labrador. Who has been no stranger to significant storms this season. Winter refuses to relinquish its icy grip. 25-40cm of fresh snow concurrent with 90km/h+ winds & blizzard conditions.

Powerful Storm to Develop Across Newfoundland & Labrador Tuesday

A seasonably-deep low pressure system will develop rapidly Tuesday; impacting Newfoundland & Labrador.

The central pressure is forecast to deepen an incredible 22mb in 24 hours, almost reaching the criteria to be considered a “weatherbomb”.

Far, and largely unpopulated, Northeastern Labrador will see snow mix-in. Accumulating snow is possible in Greenland.

Expect pounding surf of 3-5m and beach erosion in Labrador. As well as, heavy rainfall and strong winds. Strongest winds to 90km/h will remain well off the coast.

Projected Wave Heights

NEWFOUNDLAND:

Western sections will see locally-heavy rainfall with this system. The biggest weather story is focused on a sudden change in weather pattern.

Warm & humid conditions dominating the Province will end, at least temporarily, with the passage of a cold front.

A cooler much-drier airmass will move across the province West to East throughout Tuesday.
