Overview
- A large cold-front driven by Canadian air and an early polar-vortex perturbation is organizing over eastern North America and could bring heavy rain, inland snow and strong coastal winds in the coming days, though model guidance remains track‑dependent.
- Meteorologists warn the storm’s path will determine where the strongest impacts occur, with a near‑coastal track favoring damaging winds and a more inland track shifting the heaviest precipitation and snow well inland.
- Forecast guidance shows a sharp east–west temperature contrast across the U.S., with the East turning notably colder while a building high pressure keeps the West unusually warm.
- Regional forecasts for Tuesday, Nov. 10, confirm persistent, widespread precipitation in Galicia with AEMET-based products showing 100% precipitation windows and southerly gusts locally near or above 60–70 km/h.
- Argentina’s national service (SMN) reports very hot conditions in Tucumán near 36°C, instability and ongoing cordillera snow in Mendoza, and a warm Buenos Aires area with rain possible midweek; communities should prepare for travel disruption, localized flooding and power outages where winds or heavy precipitation occur.
