Morning folks! Im off for a few days but will continue to post weather updates on the page as needed...and its needed as one heck of a storm is on the way for Sunday. We will start with this mornings situation first... St. Johns received 11 cm of snow overnight, before the change to freezing drizzle this morning. This was exactly what I expected. (*To see my snowfall forecast from yesterday, scroll down one post on my facebook page*) This occurred because of the lows track...which will be pretty much right over the Avalon. West of the Avalon snowfall amounts appear to be higher, and I think the highest amounts will be found a bit farther west of where I thought they would be yesterday...but not by much. Looks like the Grand Falls-Windsor to Buchans area, and northward onto and near the Baie Verte Peninsula may end up with the highest snowfall totals by this afternoon. The reason? The heavy snow band appears to have setup there, rather than a little farther east. How much snow have you seen? Reports are greatly appreciated!! The surface and upper level low (appear to be near vertically stacked) will cross the Avalon Peninsula this morning. Another area of heavy snowfall will accompany the low, on the west and northwest sides as it goes by. This will cause snow, heavy at times, to redevelop on the Burin Peninsula, the area around Clarenville and up onto and near the Bonavista Peninsula. Even the Avalon may see a brief period of steady snow later this morning into the early afternoon. Additional light to moderate accumulations are likely on the Burin/Bonavista Peninsulas and the Clarenveille area. Another couple of centimeters may fall on parts of the Avalon too, including in St. Johns. Snow everywhere should be ended by mid afternoon. Temperatures range from near 0 on the eastern side of the Island to near -6º central and west. As the low passes and winds swing around to westerly on the eastern side of Newfoundland, temperatures will fall this afternoon to near the levels currently seen central and west. It looks like we catch a break in the weather on Saturday and before our next storm moves in late Saturday night and continues through Sunday. The track of this low will be through the Gulf of St. Lawrence, which puts Newfoundland in the warm sector. This low will also be very strong, with a surface pressure between 950 and 960 mb as it passes the Island. This means we are going to see rain (widespread 25+ mm), and very high winds. Wind speeds Sunday morning look to be sustained around 60-80 km/h, with gusts to 110-130 km/h across much of southern and southeastern Newfoundland, which includes the Avalon and St. Johns. The winds should slowly calm down during the afternoon. Much of southeast Labrador will see near blizzard conditions on Sunday as the low goes by. Expect snowfall in the 15-30+ cm range, with very gusty winds. The snow and wind will create near 0 visibility and travel will dangerous if not impossible. Ill post a more in depth update on the Sunday storm later today or early Saturday. Have a great day and stay safe! Cheers, Meteorologist Eddie Sheerr
