We loose the warm, damp and dreary regime over the next 24 hours and will return to the much more typical, cooler, crisper weather we expect to see during November. The frontal boundary responsible for the mild flow and wet weather will sink south tomorrow, fragmenting as it does so and this will introduce cooler […]
Scotland Temperatures throughout Scotland are rising to a good 4-8C above seasonal averages and in some Moray coastal locations, an impressive 10C above normal with a high topping 16C this afternoon at Kinloss. It’s all thanks to a long fetched, deep sub-tropical flow which has roots all the way back to the tropics. Unfortunately with this very balmy air flow comes […]
While we have entered my much anticipated warm and wet spell in November with a long fetched moisture plume extending from the UK back out into the subtropical Atlantic, this is not all that dissimilar to what was experienced in November 2009 when Cumbria experienced devastating flooding. This very event was something I believed could setup this year […]
As forecasted here from well over a week ago, as the western trough deepened and slid east, so the ridge pumped up the East Coast. The combination of sunshine and enough southwest wind forced temperatures to warm to levels more typical of September and not mid-November. This of course is in stark contrast to the […]
With a large vortex of low pressure dominating the North Atlantic and a huge high over Europe, Ireland and the Northern UK finds itself beneath a long fetched plume of moisture associated with a stalled frontal boundary which extends from the heart of the central Atlantic, all the way to Scotland. Incredibly, according to satellite imagery the cloud band […]
Scotland A VERY WET PERIOD WILL DOMINATE THE NEXT 48 HOURS, PARTICULARLY IN THE WEST, WATCH FOR POOR TRAVEL CONDITIONS AND FLOODING! It’s been a very damp, overcast and dreary day across much of the country, particularly in western areas, always drier in the east but here there is more mist and fog to contend with. A […]
We live in very interesting times. With the NAO/AO now positive, we’re seeing the atmosphere do what I’ve been hoping for and that is the building of cold over the source region during November. Given the negative trend in the NAO ensembles and the forecast of a return to negative later this month, this reload at a time […]
The arctic air which entered Montana first will slide across the Dakotas today and Minnesota, Wisconsin tomorrow. The arctic air is moderating as it pushes east and if you live in the East, this never reaches you! By Tuesday, the amplification starts to flatten across the country with the flow turning zonal. The door to the arctic […]
While a sprawling upper ridge builds across Europe this week promoting mild, sunny days but misty, murky, foggy and chilly nights, this extends northwest into the southern half of the UK. While temperatures range 2-4C above normal throughout the UK, it’s Scotland which will unfortunately be positioned beneath a far reaching frontal boundary which separates the large […]
There is a very large temperature spread currently between Montana and the Mid-Mississippi Valley. While temperatures are running 20-30 below normal over the Northern Rockies, it’s 10-20 above normal further east. This sharp divide is courtesy of a vigorous storm system and it’s potent cold front. Along the front, warm air is being driven northeast […]
