Weather summary
for Newfoundland

Discussion.

A low pressure system emerged from the Great Lakes on Saturday 
before crossing Nova Scotia on Sunday, and then tracked over central 
Newfoundland early this morning. Snow and strong winds arrived over 
southwestern parts of the island Sunday afternoon and spread to 
remaining areas Sunday evening. The snow then gave way to a brief 
period of rain over southeastern of Newfoundland later Sunday night. 
Precipitation tapered off over all areas this morning. 

While this system was much weaker than the powerful storm that 
battered the island late last week, it was significant enough to 
cause a setback to ongoing cleanup efforts. It also added to the 
substantial snowfall tally that has been growing larger for several 
weeks.
