It was a balmy 68 degrees or 20C yesterday in Calgary, Alberta and in previous days, highs reached in the low 20s or low to mid-70s and this morning it started snowing and continues to snow through today. Gone is the major, even record breaking warmth which allowed Western Canada to enjoy some extended summer warmth but since it’s late […]
After a long, dry and hot summer over Alaska, something much more wintry arrived this morning. The first measurable SNOW in Fairbanks! While grassy surfaces saw a light dusting around town, roads were too warm for snow to stick and for appreciable amounts, you had to go outwith and into higher elevations but nonetheless, the first snowfall hit […]
Mexico has already seen a LOT of rainfall in recent weeks from tropical systems crossing the country and with another two now sweeping more rich tropical moisture inland, we could see potentially another 20+ inches over the next few days which raises significant concern of flash flooding across a broad area. We currently have 75 […]
It has been rather quiet of late across the tropics as you would expect during the early part of the season, however we do now have a named storm on the charts and that name is Dorian. Dorian is a 50 mph storm heading west, northwest at 20 mph beneath the Mid-Atlantic ridge. Pressure is 1002mb. This […]
We are keeping a close eye on 60 mph Tropical Storm Chantal which is moving fairly quickly in a WNW direction over the Western Atlantic. Chantal is modestly organised at this time and could be considered a fairly strong tropical system with an increasingly well defined low level circulation as you can see from the below satellite image. There is […]
As we approach July, one must start watching the tropical Atlantic as the MJO index looks set to enter increasingly more favourable octants. While the GFS is going through phase 1, the ECMWF clearly shows it entering phase 2 and that’s prime time for western Atlantic development over the next couple of weeks. Quite often when the […]
It’s long been known than an increase in high latitude volcanic activity has been linked to an increase in winter blocking and colder winters in the mid-latitude world. We saw an increase in volcanic activity prior to the bitter cold winter of 2009-10 which shivered much of the Northern world including the United States and Great Britain. We are currently and have for […]

The tropics come alive this week with a threat to Florida late week into the weekend. Flooding could become an East Coast problem next weekend and beyond!
