Weather Authority Expects Best Chance for Significant Heat in First Half of Summer with Increasing Likelihood of Broad-Based, Below-Normal Temps as Summer Progresses
Andover, MA, May 21, 2012 â WSI (Weather Services International) expects temperatures for the upcoming period (June-August) to average higher than normal across the Nordic region, UK, and the northern mainland, with below-normal temperatures confined to the Southeast.
âThe last few summers have all been characterized by very warm, dry weather across much of eastern and southern Europe with relatively cool and wet conditions across the UK and western parts of the mainland and Nordic region,â said WSI Chief Meteorologist Dr. Todd Crawford. âThis pattern has been driven by extreme levels of North Atlantic blocking, which we do not expect to occur again this summer.

This year, reduced levels of blocking should result in a distinctly different summer with high pressure driving warmer, drier and less windy conditions across northern and western Europe. Conversely, lower pressures will be associated with cooler, wetter and windier conditions across southern and eastern Europe. Finally, the emerging El Nino event suggests increased chances of more widespread, below-normal temperatures by late summer with the best chances for significant heat during the first half of summer.â

RED-HOT SUMMER TO BREAK RECORDS
by Nathan Rao - Daily Express
.....According to Weather Services International, a âpressure blockingâ system which caused recent summers to be cool and wet has now moved away.
Chief meteorologist Dr Todd Crawford said: âThe past four summers have been fairly wet and cool across the UK. This was driven by extreme levels of North Atlantic pressure blocking, as seen in summers 2007-11, but that pattern has now seemingly ended.
âReduced levels of blocking should result in a distinctly different summer this year â with high pressure driving warmer, drier and less windy conditions.
âWe expect a summer pattern more like 2002-06, with above normal temperatures.â
Jonathan Powell, forecaster with Vantage Weather Services, said summer would see âspikesâ of extreme hot weather. He said: âThere are going to be some very hot periods of weather as summer kicks in.
âThese will be tempered by some periods of cooler weather but what we are expecting to see is a summer of extremes.â
Meanwhile, the May mini heatwave could last into next week. The best weather will be in central parts of the UK, although the entire country can look forward to summer-like sunshine, according to the Met Office....Click above Daily Express link to read FULL report from Nathan Rao
Summer Forecast - Please note that this forecast is a preliminary look at the some months using output from the CFS model, the full Netweather summer outlook will be available later this month.
June is currently expected to have higher than average presure acros the British Isles, meaning that rainfall will for many regions be below or close to average levels. It's worth noting though that the forecasting model does forecast some periods of higher which may see some locations ending up with a wetter than average month. Temperatures are widely expected to be warmer than normal, although for central and eastern England it may be fairly close to average.
The forecast is low confidence from this point. At this stage, July is again expected to be a warmer than average month but with rainfall close to or above average across a good deal of the UK and Ireland.
The forecasting model dries things out a little into August with many regions (particularly in the east) currently forecast to see below average rainfall. Temperatures are again forecast to be warmer than the norm for the majority. Again it's worth re-iterating that this is a very low confidence forecast.

Start of meteorological summer â June 2012
The start of the meteorological summer will bring a wide variation of unsettled weather types across the country. June will also be hampered by periods of cool and wet weather across many parts, with a noticeable reduction in temperatures for the time of the year in places. Some of these showers will also turn particularly heavy and thundery in places, with the potential for some further wintry showers of hail, sleet and snow in places (especially across higher ground in parts to the north â in what will be officially summer). The unsettled weather will also be accompanied by some very strong winds at times throughout June too.
Any periods of prolonged warmer and settled weather are relatively slim throughout June. However, one or two widespread warm are sunny periods are likely to develop, but I expect these to be very brief in nature. The best of any drier and brighter weather to be had throughout the month, will more than likely feature in Scotland and some parts of the north. Elsewhere, is likely to experience a generally unsettled and very wet theme throughout June as a whole.
Temperatures as a whole are also likely to be near or below-average for June. However, I expect the Central England Temperature to come in at below-average for June (the oldest recorded temperature dataset in the world â over 350 years old)...Click ExactaWeather link for more
