The large-scale weather pattern continues to crank into autumn gear with strengthening jet and deeper lows in which Ireland and the British Isles are in the firing line. The one factor I would say that isn’t so autumnal just yet is the temperature. The active storm track continues to favour warmer than normal but the […]
A great read!

This analysis is intended to provide researchers and practitioners real-time insights on one of North America’s and Europe’s […]
It may be a thoroughly miserable start to the weekend over Western Scotland but we remain on the warm side of an increasingly active autumn jet stream. The slow moving cold front attached to the latest Atlantic low has brought a soggy night and start to the weekend across western Scotland, especially the West Highlands and that continues through the […]
Summer is well in our rear view mirror with Meteorological Autumn beginning at the start of September and Astronomical Autumn occurring yesterday. Day and night will be exactly equal as of Sunday the 25th (equilux) meaning equal and from there on, night is longer than day. Wish to know more about our seasons? VIDEO: Mechanism […]

A storm system centred over the Northern Plains will separate the West and East from winter and summer respectively. While snow and temps 10-15 below normal dominate the West, summer lives on from St Louis to Philly with storms and heavy rain in between. As for the Northeast, following some hot summery days, fall is […]
Today marks the autumn equinox when day and night are the same length. Beyond today, night will be longer than day and this becomes noticeable as warm air masses retreat and cold gains ground to the north. With cold building and creeping southward, so the thermal gradient steps up, increasing the jet stream and therefore we […]
As we approach the end of September you’d expect to experience cooler, windier days as the jet strengthens in response to the increased north-south temperature gradient. We are indeed seeing the jet strength increase, especially when tropical cyclones push heat northward while central Greenland gets ever closer to -40C. There’s no question that the pattern is becoming more energised as we […]
Here’s some interesting thoughts on the 2016-17 winter from Stuart Markham of Chorley Weather. Always good to share and learn from others! Be sure to follow Stuart on twitter @_weatherstu Source http://www.chorleyweather.com/uk-winter-forecast-201617-la-nina-now-unlikely/ La Nina the sister of the perhaps more well known phenomenon El Nino, looked likely to develop this Autumn given all the model guidance […]
[s2If current_user_can(access_s2member_level1)] It should be of no surprise how warm last winter panned out not just for the United States or Europe but for much of the Northern Hemisphere given the strength of the El Nino. As is the case when you get a super El Nino, it takes over the global atmosphere with warmth circling the globe, breaking […]
