Well after a very active few weeks, Eastern Newfoundland is finally
catching a break from the Snow Storms. Earlier this week, it appeared St. John's
& the Avalon was set to see another 20-30 cm Snow Storm for Saturday night
into Sunday. However over the past 48 hours, as the system developed over the
Rockies and moved across the Prairies, forecast models have been tracking the system
South of the Island. As a result, we're going to dodge that bullet!
The cold temperatures which have gripped the Province all week long aren't
going anywhere, anytime fast. Below seasonal temperature will continue right
through the Weekend and into next week. Although the snow squalls have eased on
the West and South coasts, the onshore flurries remain and will also continue
through the Weekend. As winds become more Northwesterly on Sunday, the Northeast
Coast will get into some onshore flurries action as well. Have a look at the Next 36 hours. (GEM Regional Model)
A cool Northwesterly flow will continue into early next week, keeping
temperatures chilly across the Province. High pressure will settle into Atlantic
Canada on Monday and into Tuesday, bringing some clearing skies and some
Sunshine for many. Here's the long range GFS model outlook.
WARM UP COMING?
Now this is the long-long range, however as you can see from the GFS model
above, forecast models are flirting with a big warm up for the Eastern part of
Canada mid-late next week. A Colorado Low will develop early next week and move
across North America bringing all kinds of warm air from Southern U.S. along
with it. There are still some disagreements on both the track & timing of
the system, which makes this far from a guarantee. Still, consider this a heads up for
all of you snow lovers out there, get out and enjoy the powdery snow that's on
the ground now! The snap below is from the GFS model for next Thursday evening.
Notice how far West the Low is (over Central Quebec) allowing all the warm air
to pump up ahead of the system. This idea, one of a few, has the warm air and rain even pushing into Southeastern Labrador! As always, stay tuned.
MASSIVE ATLANTIC STORM
Just a quick note on a developing MONSTER of a storm in the North Atlantic.
A Low which passed South of Newfoundland over the past 24 hours is developing
into a huge Storm. Forecast models have been 'bombing' the Storm out with a
barometric pressure as low as 928 to 919 mb by Saturday morning! That would make it one of the most
intense Storms ever recorded in the North Atlantic. To give you a sample, Hurricane Sandy dropped to a low of 940 mb and the 'average' Category 4
Hurricane, has a central pressure of 920-944 mb. A very strong storm indeed!
The good news is, this Storm is moving AWAY from Newfoundland and it will
weaken somewhat as it rolls towards Iceland and the UK this weekend.
