UK regional weather forecasts could be improved using jet stream data. Weather forecasters could be able to better predict regional rainfall and temperatures by using North Atlantic jet stream data, according to new research. Climate scientists examined the relationship between changes in North Atlantic atmospheric circulation -- or jet stream -- and UK regional weather variations during summer and winter months over the past 65 years, and found that the jet stream changes were significantly associated with variations in regional rainfall and temperatures.

UK’s weather office records provisional temperature of 40.2 degrees Celsius (104.4 degrees Fahrenheit). It'll be the hottest on record if confirmed. British authorities recently described the heat as a "National emergency" and portions of the nation are under an “extreme” heat warning for the first time. Much of Europe is caught in the heat wave.
