TODAY’S WEATHER ACROSS UK & EUROPE By Mark Vogan

ABOYNE, ABERDEENSHIRE CHALLENGES HEATHROW AND SOUTHEAST FOR WARMEST UK READINGS TODAY

Note the darker yellow over Scotland and the North of England that indicate’s warmer air aloft than the brighter or weaker yellow seen over Southeast England, this may aid in making the warmest high in Britain today over Scotland than the typical southeast England hot spots.

According to a 3pm Met Office observation, Aboyne, located due west of Aberdeen and away from the cooling influence of the cold North Sea waters was reporting a reading of 19.5C (67 degrees) and this is challenging readings found around the typical warm spots in the southeast of England. Unless Heathrow continues cooling from it’s maximum at 3pm of 20C and Aboyne rises, this would mean Aboyne could be the warmest spot in Britain today.

TIREE’S 11C (52F) VERSES AVIEMORE’S 18C (64F)

The reason for Aberdeenshire being as warm and quite possibly warmer is thanks to pressure heights being slightly higher than those over the southeast of England. The warmer theair, higher up in the atmosphere or the higher level in which the clumn of air can commence it’s sinking process, the warmer temperatures on the ground below can go. Wind and cloud cover also influences this process of course, Meteorlogists often look at the temperature at the 850mb level or 5,000ft above the ground to work out what the temperature will be. The local envirnonment plays a big role, where the surrounding hills are and where are the winds blowing from. This can be where highly localised micro climates can come in.

The conditions across Scotland are such that winds are blowing in from off the sea and thus temperatures are only in the 11 to 13C range despite sunny conditions. Inland highs are pushing 18 to 20C and any breezes crossing up and over hilly (inland) terrain may be adding a little downslope/compressional warming, perhaps warming Aboyne and Aviemore to the levels their seeing this afternoon. However, light winds and high pressure sitting almost directly overhead will also help warm the ground up nicely too!

TODAY’S WEATHER ACROSS AMERICA By Mark Vogan

Sadly the front’s final throws came at high price over the Carolinas and Virginia, US skies have been scraped clean of bad weather for a few days at least but storms and rumors of storms will return!

It’s very sad when looking at pictures and video coming out of the Carolinas and Virginia from the spate of tornadoes that wrecked havoc. It’s certainly one of the more crual aspects of US weather and springtime in this country.

Unfortunately, the next 48 hours will be a short lived window for damage assessments, cleanup and a chance at starting a long, tiring rebuilding of lives. The pattern is a very active one at this time and another storm is set to cross out of the Rockies and onto the Plains early to mid week and I do see a growing potential for similar weather across the same areas.

So far this spring, we’ve seen likely well over 500, perhaps even 600 tornadoes, with a record 241 this weekend alone and with not only a new storm brewing for early week that’s going to most certainly produce more, more storms will cross the country over the coming weeks ahead, could the 2008 tornado record of over 1000 fall? If it doesn’t, it will most certainly be threated that’s for sure given the pattern in place at the moment that I don’t see changing.

High pressure builds back into the Northeast and Middle Atlantic after a weekend of soaking rains and even their own share of severe weather. However, after a sunny respite, this region too will once again return to wind, rain, thunderstorms and cool temperatures perhaps by late Wednesday or Thursday as the front approaches. Stay tuned for details on the upcoming week’s return to stormy weather tomorrow.


WEATHER TALK
By Mark Vogan

If the 2008 Severe Weather Season is like 2011, does that mean a similar hurricane season to 2008 also?

If the warmer than normal Gulf is creating or at least fuelling this record breaking Severe Weather season, What does that mean for the Hurricane Season?

It would appear that warmer than normal conditions in the Gulf of Mexico may be adding fuel to the fire in relation to this spring’s severe weather season which is strikingly similar to 2008. If that’s the case that Gulf waters, that are warmer than they should be is aiding in creating a worse severe weather season, then does this mean a worse hurricane season also?

Of course it can greatly depend on the track of cyclones once formed, but could there be larger-scale influences based on a warmer Gulf? Eg. warm water can feed back to the atmosphere, enhancing upper level ridges, forcing stronger upper winds and or re-routing them too.

The problem is, if the hurricane season mirrors or is at least remotely similar to 2008, we can only fear that as we saw Gustav and Ike, two powerful hurricanes that went into the Gulf. We all know what Ike did! 

A mere food for Sunday evening thought, I’m not trying to scare but share the facts and some of my thoughts.

Only time will tell.
