We unite in celebration Canada Day, but weather-wise there will be quite the divide across the country.
A breakdown of the July 1 forecast for each region can be found, below.
A broad upper-level low continues to keep temperatures in B.C. below seasonal, also bringing unsettled conditions, through Canada Day. The greatest chance for seeing a relatively dry day would be along the coast. The Interior will see cool and showery conditions persist during the day.
The western Prairies will be stuck in a below seasonal, wet pattern through Canada Day. Alberta will see periods of rain continue, with heavier precipitation in the north, which may include embedded thunderstorms. Daytime highs will struggle, climbing only into the mid-teens.
With cooler air aloft focused over Alberta, parts of the Rocky Mountain peaks may actually see some snow early Wednesday morning as freezing levels drop.
Northern Saskatchewan will see periods of showers and embedded thunderstorms, while southern regions will be mainly dry. Manitoba will see the threat for severe thunderstorms mid- to late-day as temperatures in the upper-20s fuel instability.
A mid-summer day is forecast across Ontario with temperatures climbing above seasonal in the north, reaching the low-30s. However, the southern half of the province will sit close to seasonal with daytime highs in the mid-to upper-20s. A threat for thunderstorms will increase through the evening for parts of the north while the south basks in sunshine.
An upper-low, semi-stationary over the northeastern U.S., will fuel the threat for thunderstorms across the Eastern Townships and along the St. Lawrence River. Temperatures across northern Quebec will sizzle in the low-30s, while the southern section of the province will sit comfortably, near seasonal, in the mid- to upper-20s.
An active and wet pattern continues for parts of Atlantic Canada through Canada Day, with Newfoundland expected to see periods of rain, although some breaks can be expected. A thunderstorm risk will creep into western parts of the Maritimes late day, courtesy of an upper-level low sitting over the northeastern U.S. Temperatures are expected to be in the low- to mid-20s range.
Mainly sunny skies are expected for Iqaluit and Whitehorse. Yellowknife will be warmer, but with the chance of showers.
