A typical spring pattern is shaping up across North America with up-and-down temperature patterns due to a wavy jet stream pattern.

-- There will be a brief period of heavy rain across the Maritimes early Thursday with the potential for over 30 mm of rain and strong south to southeast wind gusts.

-- Chilly air will return to eastern Canada this weekend with significant trough building across the region. This may even result in some snow showers in the Ottawa region Saturday night into early Sunday,

-- There will be a big warmup for eastern Canada next week (Mon-Wed) as southwesterly winds send warm air into Ontario and southern Quebec. Temperatures will likely peak Tuesday above 20 degrees Celsius over many areas, except those that are downwind of larger lakes.

Projected afternoon temperatures for Tuesday.

--There will be a significant warmup late this week across western Canada, but much cooler air will come into Alberta Sunday into Sunday night with the potential for some snow in the mountains and foothills.

--A strong West Coast ridge will likely dominate for the first week of May, which will likely lead to well above-normal temperatures and below-normal precipitation for BC. At the same time, it will turn cooler in the central and eastern Prairies and wetter across the Great Lakes and Ontario.
