Warming up again



Now it's warming up again, the risk of air frost has probably gone until the autumn. The minimum temperature (2.2 Celsius) that occurred the night before last, was the equal lowest during the second half of May in Morden for at least 20 years. A similar minimum occurred on the night of the 28th/29th May 1994. An air frost did occur in a few places on Monday night, with minus 0.3 Celsius recorded at Farnborough (Hants). The cold air originated north of the Arctic Circle, and when it crossed Finland, minima of minus 10 Celsius occurred, resulting in much damage to apple blossom.
