Autumn 2015
Thanks to a pretty deep trough driving into the Northern Plains, a July-like heat pump has been forcing the hottest September air in 32 years up through the Northeast. The last time it was hotter than yesterday at this time of year, I was just 7 months old. Yesterday was also the hottest day of the year for New York and […]
In the last week, the upper pattern is been pretty much opposite of the summer with a blocking high across the north while low pressure has run underneath. The system which brought the flash flooding to parts of Spain last weekend is now crossing the Mediterranean producing very active weather over Sardinia, Sicily, Italy and eventually […]
Well it may have taken till autumn but the hottest temperatures of the year have arrived in the Northeast. Today not just represents the hottest day of summer for NYC but 5th 90+ for Sept and most since 1983. NYC also sits in 3rd place for most 70+ degree nights since 1950. Boston’s 96 is […]
While heat has been the main story throughout this summer across Europe, it’s storms that’s now taking centre stage. The upper air pattern is one similar to the last two July’s and opposite the past June-August period with strongest heights extending from the Atlantic across the UK into Scandinavia. Here’s the current upper setup. Lower heights […]
A very brief post this evening. Taking a particular interest in New York. Some records broken or tied on this Labor Day. An all-time record consecutive 80+F days continues. Interesting this Labor Day is about 20 degrees warmer than on July 4th. A look back at past Labor Days. Think the 65 day stretch of […]
From Met Office The following represents an assessment of the weather experienced across the UK during Summer 2015 (June, July and August) and how it compares with the 1981 to 2010 average. Summer 2015 was mostly characterized by a cool, westerly Atlantic flow with the UK often under the influence of low pressure systems; eastern […]
September sure has gotten off to an extreme start on both ends of the temperature ledger with record cool in the Pacific Northwest while it’s been record warm over the Plains through Great Lakes up into Canada. Pretty much opposite of summer. Yesterday was one of those extreme days. 20 below verses 20 above within a […]
Long range forecasting is often seen to be impossible and laughed at. However it’s predictable if you know what your looking for. Some years I struggle and get it wrong, other years like 2015, I get it right. The lessons learned from 2012 have certainly paid off this year. Right or wrong, here you get […]
We’re into September and approaching the height of the arctic sea ice melt season. This usually coincides with regeneration of cold over the pole and the sun angle continues to lower from it’s peak back on June 21. There’s a lag of about a month between longest day and warmest time of year but by late August, […]
As we head into September I continue to watch the overall global pattern and the primary drivers. The El Nino is strong and influential to the global circulation, however as I’ve pointed out previously, there are competing factors which suggest there’s nothing obvious as of now. By that I mean we can’t just look at this […]
