Meteo Quebec as the week begins: springlike warmth before a midweek storm
meteo quebec is delivering a notable springlike pause as the week begins, with forecasts showing daytime highs reaching at least 15°C in Montreal and Sherbrooke and up to 18°C in the southern part of the province.
What Happens When Meteo Quebec Forecasts Double-digit Days?
The early-week push of mild air has raised temperature forecasts and record-watch interest. Forecasts show the potential for unusually high readings: up to 18° in the south, at least 15° this afternoon in Sherbrooke and Montreal, 10° in Quebec City, 9° in Val-d’Or and Rimouski, and 6° in Chibougamau after lunch. Overnight warming from Sunday into Monday pushed temperatures above 0° across the south and centre of the province.
Historical markers highlighted by the recent readings include the possibility that this March observation could be the warmest since a year in the early 2000s when Montreal reached 16. 8°. Records of high minimum temperatures from 1973 were broken on March 8 in Montreal, the Outaouais and Ottawa. Maximum-day records for March 9 from the year 2000 (Ottawa 19. 2°; Montreal 17. 4°) frame how exceptional current projections would be. If Quebec City reaches 10°, that would surpass a 1977 March 9 record of 8. 7° for that location.
What Happens When the Warm Spell Meets a Midweek Storm?
The mild interval is temporary. Environnement Canada forecasts a strong weather system moving in beginning Tuesday evening that will bring a mix of snow, rain and episodes of freezing rain across large parts of the province. The western regions can expect rain and the potential for freezing rain in Abitibi-Témiscamingue, where daytime readings may be near 10°C before the change. Capitale-Nationale, Saguenay and Côte-Nord are likely to receive rain with some snow at higher elevations. A weather bulletin from Environnement Canada singles out the Saint-Lawrence valley for an episode of rain and freezing rain.
Practical takeaways for the period include the contrast between bright, mild conditions early in the week and a sharper, wetter pattern later on. Environnement Canada also notes an alternation of sun and clouds across southern Quebec with more limited warming in some eastern sectors where highs near 9°C are expected. Some inland northern areas could still receive measurable snow — an example forecasted amount is about 5 centimetres in parts of Abitibi even as temperatures remain comparatively mild.
- Montreal & Sherbrooke: at least 15°C this afternoon
- Southern Quebec: up to 18°C in places
- Quebec City: around 10°C (record watch if reached)
- Val-d’Or & Rimouski: about 9°C
- Chibougamau: near 6°C after lunch
- Abitibi: possible 5 cm snow under mild temps; risk of freezing rain in some zones
- East-of-Quebec sectors: highs near 9°C; Sept-Îles example of colder pockets
The forecast work has included collaboration with Bertin Ossonon, meteorologist, reflecting the mix of mild, record-adjacent readings and a clear risk of a later, more disruptive system.
Readers should enjoy the sunny, milder window while preparing for a return to unsettled conditions: plan outdoor activities for early in the spell, keep winter traction options accessible, and monitor Environnement Canada briefings as the system approaches. Stay ready for a rapid shift from the current lull to rain, snow or freezing rain later in the week — meteo quebec
