Convective Discussion
A cold front will sweep across Labrador today from Quebec and continue through the Maritimes and Newfoundland on Wednesday. There is a slight risk of convection over western and northern Labrador today, but the air mass is expected to be too stable with warming 500mb temperatures as the font continues tonight and Wednesday across the Maritimes. Nonetheless, there could still be some heavier pockets of rain in TCUs with precipitable water increasing to 40 mm over the Maritimes, but the front is forecast to move through quickly, which will limit rainfall amounts.
This cold front ushers in a cooler, drier air mass under a strong high pressure system that will suppress any convection in the region until at least the end of the week.
