This morning comfortably marked our coolest of autumn so far with a widespread frost and minimum down to -5C at Tulloch Bridge. As our high slides off to our south, milder maritime air will quickly return overnight tonight.
Sunday’s northerly air flow followed by Monday’s high pressure set the scene for this morning’s cool, crisp and frosty start but it’s our pattern is transient meaning the high is easily pushed south and mild, moist SW winds return to make for a much cloudier, at times wetter and mild Halloween.
See how the cold is replaced by the mild within a day.
Today
Tomorrow. (jet stream and 850 temps)
With colder air now within our mid latitude air flow, low pressure opens the door to another taste of cold and northerlies come Thursday!
Then again next weekend in the wake of another low.
On the whole, we’ll continue to see a classic up and down regime thanks to the persistence of the westerlies. Thanks to the return of a positive NAO.
