Perfect September Weekend for Montreal

The entire region continues to benefit from high pressure stuck over Quebec. Light winds and clear skies have allowed for cool nights but warm days. A few periods of cloud cover have occurred in Montreal, as is typical in the fall, but no precipitation has been recorded. One of those periods is occurring this morning as a low deck of stratus cloud cover crosses the region. This will move out soon with nothing but sunshine through the weekend. Temperatures will be well above normal during the day from 20 to 23C (70-75F) and cool, near normal nights at around 5C (41F). Some fog may also develop after midnight as the air becomes quite moist in the longer overnight hours. A few clouds may occur Sunday night along a weakening cold front, but otherwise look for more sunshine and well above normal temperatures through next week. A coastal storm will remain to our east with no weather from it here in the St. Lawrence Valley.

While it remains dry here in Montreal, there is some weather out there. A Pacific storm dumped heavy snow across the Rockies and coastal mountains this week. The photo above, from The Weather Channel, is deep snow at Crater Lake Lodge in Oregon. More snow is forecast this weekend. Soggy, stormy weather will occur from B.C. into Saskatchewan.
With very tranquil weather in Montreal to close out September we have to look elsewhere for storminess. A large and strong Pacific storm will slam into south coastal British Columbia and the Pacific Northwest this weekend. Early estimates for rainfall are in the 60-120mm range with 60-80km/h winds. There will also be more snowfall at the highest elevations.
