Danielle to Remain at Sea and catch High Pressure weakness, But could the system behind Danielle (Earl to be?) be something to worry about down the road?
By Mark Vogan
Danielle, currently blowing at 80mph sustained winds is showing signs of catching the trough out but what is lurking behind Danielle is something perhaps paying more attention to as Danielle now only laying down the path for this system to develop like if not easier than Danielle is the same area, a moistened wake behind, may help fire the wave into Tropical Storm Earl. My thoughts are that Earl (to be) may find itself tracking FURTHER west, missing any weakness in the mid-atlantic ridge and may cross into a better overall atmospheric and oceanic environment to become a major issue 10-days from now over the Western Atlantic. Stay tuned!

Colliding air streams and surrounding warm water continue to bring flooding downpours to areas of UK

Because the base of the trough sits right over the UK airspace at this time and low pressure impules are riding an overhead jet stream, we are basically right benath a cross-roads of air masses as cold air flows down from the north and warm, moist, humid air flows north, slamming up against a boundary that covers British airspace. Last night and into the early hours of this morning whilst driving between Bathgate and Burton-Upon-Trent, Derbyshire, the skies were cloudy and the rain at times drenching between Glasgow and Preston, beyond Preston, the skies couldn't be clearer and with a full moon. In fact apart from a chilly breeze, which at times was strong, creating a little rocking around of cab and trailer on the exposed sections of the M74 and M6, overall it was a lovely night. It showed me that these "pulses" riding southeastwards along the boundary was dropping down and colliding at the base of the trough with a stream of warm, moist air flowing up from the sub-tropical Atlantic, this indeed has been forcing torrential donwpours, heavy of course to create flooding, some in fact in the nature of "flash-flooding" due to it's intensity.
The cooler air and chilly wind was indicative of the northwesterly flow, but down over southern England it's milder and these two air masses are creating the torrential rains at this time and look like they'll continue. The other big factor is not only the upper-level pattern and support of the jet directly overhead, but the warm surrounding waters... It's geography verses a large-scale cyclical pattern.
