Russia Heat Wave Set to Worsen, Persist into Next Week

The Russian heartland, already reeling from record heat aggravated by drought, will swelter under extreme heat for at least another seven to 10 days.

Most of western Russia will have average temperatures of 10 F to 20 F above normal through the end of July. Highest temperatures forecast through mid- to late week are 95 F to 100 F with 105 F in hot spots of southern Russia.

Most normal average daily temperatures in this area range from 60 F to 70 F with normal high temperatures mostly between 70 F and 80 F.

The Russian media have already labeled 2010's heat and drought as the worst in 130 years. Agricultural officials have said that grain output will be cut by 20 percent as tens of millions of acres of crops have been damaged or destroyed.

Drowning deaths have soared as people take to the water in droves.

The trigger for the abnormal heat and drought has been persistent high pressure anchored over European Russia together with southwest-to-northeast trending jetstream from the Atlantic coast to the European Arctic. At times, low pressure has dipped over southeastern Europe thereby further bolstering the heating.

Under this overall pattern of steering winds, desert heat has been tapped from North Africa, Arabia and central Asia and fed northward to the heart of Russia.

This weather setting will persist and even intensify during the next few days.
