Colder-than-Normal Temperatures Likely to Return in Late Autumn
Andover, MA, August 22, 2011 — WSI (Weather Services International) expects temperatures for the upcoming period (September-November) to average higher than normal across all areas in Europe, except for the UK and parts of France and Benelux.
“High-latitude atmospheric blocking, as manifested by the negative phase of the North Atlantic Oscillation (NAO), has been in control again this summer. This has resulted in lower pressures across the UK and northwestern Europe, while higher pressures and generally warm summer temperatures have been the rule elsewhere,” said WSI Chief Meteorologist Dr. Todd Crawford. “We expect this pattern to reverse at least temporarily during the first half of autumn, with below-normal temperatures becoming more common across southern regions and above-normal temperatures becoming the norm across the UK and northern regions. As we head deeper into autumn, however, the influence of the NAO will likely become more predominant, and a return to below-normal temperatures is likely sometime in November. While it is still quite early to make confident winter predictions, an initial analysis suggests that a winter closer to what was observed in 2008-09 might be in the offing. It may not be as severe as the last two winters.”
In September, WSI sees the monthly breakdown as:
Nordic Region* – Warmer than normal
UK * – Warmer than normal
Northern Mainland* – Warmer than normal
Southern Mainland * – Cooler than normal, except Iberia
In October, WSI forecasts:
Nordic Region – Warmer than normal, except Denmark
UK – Cooler than normal
Northern Mainland – Cooler than normal
Southern Mainland – Cooler than normal, except Iberia
In November, WSI forecasts:
Nordic Region – Warmer than normal, except Norway & northern Sweden
UK – Cooler than normal
Northern Mainland – Warmer than normal, except parts of France/Benelux
Southern Mainland – Warmer than normal, except Iberia
