Yesterday was a washout across the southern UK and the first of July. This was good for gardeners but not so good for sun worshippers. Yesterday afternoon’s radar. Nearly 2 inches fell in spots. Dreary old day over London. Covers were on at Wimbledon for the first prolonged period of the tournament so far. After […]
Semi permanent upper level ridges over the Southwest tend to fluctuate in strength during June and July but persistency in strong 594-597dm heights this summer is unusual. These cells tend to build into the 594-600dm range for only 3-6 days before deflating and are typically followed by weaker cells but this summer wants to hold onto the heat wave producing 594 to 597dm. Heights have fallen this […]
Thunderstorms swept across metro Paris Sunday evening delivering 2.1 inches of rain in just 2 hours and 1.9 inches within 1 hour which set a 24-hour rainfall record for July and all-time hourly record. This broke the previous hourly record of 1.8 inches set in July 1995. On the southern edge of central Paris, Montsouris Park received 2.6 inches […]
Heat is normal, so too are heat waves but the persistency of this summers intense heat is unusual even for the Southwest. If it continues then I wouldn’t be surprised if this turns out to be one of the hottest summers on record. Las Vegas tied it’s all-time record last month and during the past weekend, the thermometer […]
Thanks to low pressure over Spain, S, SW winds blowing off Africa has enhanced an already warm air mass affecting the Balearic Islands Friday. On the western side of Mallorca, open to the Saharan wind, temperatures touched the 40C mark which is rare for here. The 40.1C recorded at Palma Airport Friday was just 0.5C shy of the July […]
It wasn’t tropical storm Nanmadol to blame for the 15 inches of rain which fell in just 4 hours across southern Japan but convergence along the semi permanent baiu frontal. This front dropped south out of China bringing warm, moist air from the SW and cool, dry from NW in the wake of the TS. A record 542mm of rain fell within 24 hours and […]
We’re in the heart of the Northern Hemisphere summer with heat as you’d expect, dominant. However it’s anything but summer-like in Greenland where temperatures dipped to a new July record this week. July has opened very cold across most of Greenland. The temperature dipped to -33C (-27.4F) on the morning of July 4th at the DMI recording station, perched 10,551ft on […]
A powerful upper ridge continues to bake the Great Basin and Northern Rockies in temperatures 10-15 above normal this week and through the first half of the weekend but that core of heat shifts onto the Plains next week. This summer’s heat should peak in SW California including the LA area during Friday. Drought has worsened in the […]
Before touching on today, I just want to throw up the maximum temperatures across the UK from yesterday and check out the contrast between Scarborough and London… As forecast. It’s even warmer and more humid in the South this afternoon. Thanks to low pressure drifting over Kent from the Bay of Biscay, it’s also a stormy July afternoon/evening. A fairly warm air […]
