It’s turned crazy warm over the Western interior and Plains thanks combination of dry ground, lack of snow and a digging trough bringing snow to the Sierra Nevada and strong downsloping SSW over the Front Range. Denver climbed to a new November benchmark of 81 degrees this afternoon besting the previous record of 80 degrees […]
Steep 5-7 day rises in temperature over Greenland typically heralds a developing -NAO and that’s exactly what we’re seeing now which promises a chilly week dominated by northerly winds over the UK. Temps have went from -55 to -22 and it’s likely to warm further in the next few days. The reason for warming is […]
The tremendous swath of warmth spanning an area from California to Great Lakes shall shift eastwards as we close the books on November and begin December. November has very much been categorised by a cold north, warm south which La Ninas tend to favour. Thanks to strong high latitude blocking, a warm US doesn’t typically […]

Looking ahead at next week, it appears we firmly hold onto the cool theme once a system sweeps through tonight and tomorrow.

This week has seen the first -50C of the season in the Northern Hemisphere (outside Greenland). The coldest inhabited place on earth, Oymyakon dipped to -52C in recent days. That’s the lowest […]
As expected, thanks to an unusually large and strong upper level ridge, Thanksgiving Day became the hottest on record for many sites stretching from Los Angeles to the Dakotas. Looks like Lake Elsinore, CA tied the US Thanksgiving Day record high with 97 degrees. The NWS San Diego weather balloon measured a summer-like 994dm […]
We were graced by plentiful wintry showers, snowy scenes, bracing NW wind and temperatures which barely cracked 2-4C today. All thanks to a cold NW flow with origins extending all the way to Greenland. This was the scene on the M9 near Stirling around lunchtime. Near Dalwhinnie at around 2pm where the temperature was 0C.

November 2017 will be remembered as a chilly North, warm South with an impressive opening arctic outbreak which broke long standing records from Montana to the Mid Atlantic. It’s also going to be remembered as very snowy in the interior Northwest, perhaps a top 10 cold month over parts of the Northern Plains and will […]
