On this date last year it was mostly sunny and 18 degrees in Halifax, 22 in Moncton and the Annapolis Valley and, wait for it, 21 in Bathurst!  Today, the expected highs will remain below normal, as much as 6 or 8 degrees below normal in some places.

So what’s going on?

 The answer is blowing in the wind, literally! Right now, there’s a large spiraling storm 1800 km WNW of the Azores.  Maximum sustained winds are close to 85 km/h; tropical-storm-force winds extend outward up to 370 km from the center.

 With this kind of set up, it’s not so much about the wind speed as it is about the direction. 

The counterclockwise circulation around the low is pushing wind onshore here in our region.  That can be refreshing in the summer, but it’s downright nasty in April.   Sea surface temperatures just off the coast are in the low single digits. Air coming ashore will need a lot of help from the sun to warm things up.

By the way, that storm is tropical storm Arlene.  It’s only the 2nd time in recorded history that a named tropical storm has formed in the Atlantic Basin in April.  The other was Ana, in 2003.

Arlene is expected to drop below tropical storm force and dissipate later today.

Once the upper flow changes, we’ll have a better chance of returning to seasonal temperatures. Right now that should be 7 to 10 degrees during the day and -2 to 1 at night.
