Post 1 – 5:49 AM NST (5:19 AM AST)

A weak disturbance will traverse the Province today. This will bring some light snow and flurries to Labrador, the West Coast, parts of the Southwest Coast, and interior Newfoundland. Outside of the mountains in western Newfoundland, less than 5 cm will fall in the areas that see snow today. The snow will end late this afternoon for the Island and a bit earlier in much of the Big Land.

Southern, central and eastern sections of the Island will see light snow mixed with rain or just light rain showers this afternoon, ending this evening.

Today’s highs for the island and southeast Labrador will be near or a few degrees above freezing. At the same time, a cold front will charge through northern and western Labrador, knocking temperatures back to the minus teens and 20s this afternoon and evening.

Rainfall and Winter Storm Warnings, along with a Winter Storm Watch and a Blowing Snow Advisory, are in effect for various areas of the Province from Wednesday morning through late evening or early Thursday.
Rainfall will be heaviest in the south and east, exceeding 50 mm for many locations. Areas farther north, still under the rainfall warning, will see lower amounts of rain. However, with temperatures being so warm and upwards of 30 mm of rain in the forecast for Wednesday, rapidly melting snow and localized flooding are a concern.
The snowfall forecast is a bit more trick, but overall, 10-20 cm is in the forecast for parts of central, western, and northwestern Newfoundland. Amounts may be locally higher.
A Wind Warning is also in effect for St. John’s and the Southern Shore, along with the Avalon Peninsula Southeast for Wednesday night, for gusts as high as 100 km/h.

The highlights from his system are as follows:
