The Overview

An area of low pressure will slowly move from the western Gulf of St. Lawrence through Labrador during the next 24 hours. The low is going to bring rain and some wet snow in Labrador and rain over the Island during the time frame. The rain on the Island has already arrived on the West Coast and will move to the east this evening and tonight. The rain will end on the West Coast this evening but will continue on the Northern Peninsula, Central, the Northeast, and the Avalon and Burin Peninsulas overnight. Labrador will also see rain overnight, mixed with wet snow in the higher terrain.

The rain many of us see on the Island is along a cold front. That cold front will slow down near the Avalon overnight and Thursday. Along that front, there will be a fairly persistent area of heavy rainfall that will continue throughout Thursday. Most computer models suggest that the front will hang just offshore of the Avalon’s east coast, keeping the rain offshore. However, if that placement is a bit wrong, the heavy rain will fall over the eastern Avalon. Unfortunately, I will not know if this is the case until the rain falls on Thursday. The predicted rainfall forecast

As you can see, the area of heavy rainfall is a bit farther east than yesterday. But it would only take a small shift to have that rain fall over the eastern side of the Avalon.
