Seasonal Forecasts
In Northwest Europe, water continues to plague while in the Southwest it’s fire. Beneath the rain bearing Atlantic jet stream racing over Glasgow at 40,000ft, surface temps only mustered 12-14C but instead of a cool, moist oceanic flow from the west, Gran Canaria basically endured the opposite with east winds blowing scorching hot air straight off the Sahara across Gran Canaria and […]
A system pushing through the N Rockies is drawing hot and humid air northward up the Plains while an upper low drives cool, dry Canadian air over top enhancing thunderstorm and severe weather potential later today and tonight for the northeast Plains/Midwest. This system will continue east through the Great Lakes pushing the heat, humidity to the […]
First and foremost, on this day back in 2003 we set a new UK all-time record high of 38.5C at Faversham, Kent. Scotland also witnessed it’s hottest day with 32.9C at Greycrook. Today is quite different beneath a fresh northwest air flow. Following a new summer minimum of -1C last night at Dalwhinnie, it’s a cool and […]
From a seed in the deep equatorial rainforests of Africa, a cluster of waves rode the AEJ into the 80+F waters of the tropical Atlantic. With the combination of warm water and good atmospheric conditions, 96L was born and days later TS Earl was born west of the Lesser Antilles. Over the even warmer waters of the southwest Caribbean Sea, Earl […]
What a difference a few days can make when winds turn from southerly to northerly, even in the typically sunniest, warmest part of the UK. On the same day Cairngorm Summit recorded a wind gust of 115 mph (Sunday), Cavendish, Suffolk reached 28C making them the UK warm spot. Thanks to a wind shift, this morning’s low dipped […]
An upper low and stalled frontal boundary over 85-90F water is fuelling an ongoing major flood situation from Tampa to Panama City extending up the Gulf Coast to Mobile and possibly as far as New Orleans. A constant injection of rich tropical moisture flowing over a record warm Gulf of Mexico into the low means some areas could see over 24″ […]
A combination of factors including jet stream, pressure and thermal gradient all came together to produce rare UK summer wind speeds yesterday. We had a tremendous sea level pressure gradient anomaly of -3 sigma within the cyclone off Scotland’s north shore and +2/3 sigma over Europe yesterday morning. Visible satellite yesterday morning. Wind events do occur in […]
Aside from heat and humidity we have two other significant weather stories currently unfolding, 1) the remnants of Earl may cross Mexico and get out over the warm waters of the east Pacific and reform and 2) a stalled system over the northeast Gulf of Mexico could drop up to 20 inches of rain in NW […]
We have a strong upper ridge over the Canaries extending into Iberia while we have an unusually deep summer low approaching Scotland which has forced two very different warnings on either end of Western Europe. Here in Scotland our weather turns from warm sun this AM to gales and rain this evening/tonight. This morning’s infrared satellite view 500mb height […]
By Jason Samenow Capital Weather Gang August 4 Hurricanes, large and small, have eluded U.S. shores for record lengths of time. As population and wealth along parts of the U.S. coast have exploded since the last stormy period, experts dread the potential damage and harm once the drought ends. Three historically unprecedented droughts in landfalling U.S. hurricanes […]
