TODAY'S WEATHER ACROSS SCOTLAND, UK & EUROPE
By Mark Vogan
High Pressure allows Great Britain to enjoy warm sunshine by day, cool by night! Fresh Cold Push for Scandinavia once again coming by Weekend!
Sunshine has been the dominant feature across much of the UK today and over recent days, replacing the cold, stormy pattern of the last 10 days. In fact, on the morning of Wednesday March 9th it snowed as my wife and I drove to Glasgow Airport to catch our flight to the US. The days which followed brought strong, gale-force wind, rain, hail and snow along with below normal temperatures, those days of stormy, cloudy cold and unsettled days have been replaced by a more stable, calmer weather pattern with high pressure returning which in fact helped produce the UK's warmest weather of 2011 yesterday. At Bridlington in Yorkshire the temperature rose to a spring-like 17C and elsewhere most areas saw 12 to 14C. The strong late March sun and longer hours of daylight is allowing warmer temperatures with the high pressure cell.
As you can see from the above European map for today, it shows the high pressure system sitting slap bang over Britain and this is welcome to winter weary Brits. In fact the high stretches from the eastern Atlantic all the way to Germany and central Europe, meaning mild, sunny conditions prevail across this entire region with cool air replacing mild air after sunset thanks to those clear skies which allows radiational cooling by night. Further east and cooler air resides over the Black Sea, however even the Baltic Sea which has been frigid this winter and western Russia which saw a frigid past 5 to 6 weeks is enjoying that much warmer air much of Europe including Britain is enjoying.
TURN TO COLDER FOR MUCH OF CONTINENT BY FRIDAY AND THROUGH THIS WEEKEND!
Unfortunately, if the European is correct, a fresh push of cold air will drop south once more from the far north back across Scandinvia and into the Baltic States by as soon as Friday as you can see from the European above.
As you can see from the graphic above for Saturday, that trough of cold, Arctic air will continue to pushing south into much of northern and central Europe but this southward migrating trough will be restricted once it hits up against an increasingly strengthening sub-tropical ridge that's building northwards from North Africa. That ridge is fairly strong and dominant over the Med and southern Europe at the moment and thanks to the late stage in the season, cold air really doesn't make it into southern Europe from now on and this will hold true this weekend whilst the continent overall cools down considerably.
The time of year is now going to show more and more as we progress into spring and towards summer and the sub-tropical high becomes the dominant force over this region.
HIGH PRESSURE AND MILD AIR RETURNS TO BRITAIN BY NEXT WEDNESDAY (30TH) AND PUSHES EASTWARDS!
By the midpoint of next week, the European as you can see above shows the return of high pressure back over Britain and this looks possible to migrate eastwards across the continent like we've been seeing this week.

Mark Vogan's March, 2011 Vacation to New Jersey and Tri-State Area
PART 1
On arrival to the Northeastern US on Wednesday March 9, 2011 it was cloudy, rainy and quite windy. The latest in a series of storm systems was barrelling through. In fact it was just like what we had left behind back in Scotland.
However, unlike the UK, high pressure systems which move in behind storm systems, often pumping mild or even warm air north and northeastwards from the South, can and does bring upper 50s to upper 60s and this was the case during the 2-4 day stretch after the first 2 that brought rain and gusty winds.
The American South by late March can easily warm into the 70s, even 80s as the sub-tropical ridge begins to have it's effects felt from Mexico and the Gulf. Once storm's exit off the Eastern Seaboard and high's slide off the Southeast coast, winds from this warm region blow up the coastal plain, east of the Appalachain chain and into the Washington DC to New York corridor.
As for the further north UK high's which park themselves overhead pull mild, but hardly ever 'warm' air in thanks to cold surrounding waters which greatly modify this milder air that's sometimes dragged northeastwards all the way up from the Azores. Temperatures as warm as the 60s or even 70s that get all the north to Boston, often travel all the way from Monterrey, Mexico with no cold water to modify the air. The Appalachain mountains often help further heat air travelling northeastwards into the big cities.
This very pattern of high pressure behind a storm system allowed bright sunshine to prevail just 2 days after arriving in the Mid-Atlantic and Northeast and we were able to enjoy upper 50s along the beaches of the Jersey Shore to low 60s inland. Remember the ocean water temperatures off the Jersey and entire Mid-Atlantic and Northeast coast is still in the chilly 40s and 50s and off New England, the 30s during mid to late March.
