>HOW DID CUMBRIA, ENGLAND EXPERIENCE SUCH HEAVY, PERSISTENT RAINFALL THAT LED TO A NEW NOVEMBER RECORD?

I am gathering my thoughts of the recent storm which by the way, forced me to detour some 20+ miles this morning down in Dumfries and Galloway, because of many areas flooded.. Why we experienced such torrential rains and for a long period of time.

We are use to gales and heavy rainfall from the frequent visits from Atlantic fury, however, I wasn’t really at all surprised when I read that Cumbria recieved a stunning FOOT of rain within 24-hours, making for a new November record for the UK..

I shall have more tomorrow (hopefully) if I have time and am not too tired…

Initial thoughts.

1) A strong 957mb low which by the way was well off the British mainland, so why the extremes?

2) This low originated within the tropics and was once known as category 2 hurricane Ida. Thi begs the question, that despite it’s total transformation into a cold-core baroclinoc Atlantic low, did this system store added fuel. i.e. more moisture than a normal Atlantic low?

3) A major factor I believe.. The southern jet stream connection. If coupled with energy dispersed by the low and inject a sub-tropical jet stream with a long plume of moisture, into an already soaked circulation and fuse the jet and low into one narrow channel, then major rains are inevitable.

4) The crucial factor within this idea is WHERE THIS PLUME OF MOISTURE HIT and directly…

A hilly region of the UK, exposed on the western side of the country. Orographic lift created by the Lake Districts mountainous topography as well as a similar terrain just north of the Lakes in Dumfries and Galloway also experienced the worst of the rainfall and floods..

Even up in the central belt, major travel issues arose as the rains were relentless. However the direct wrath of a moisture plume stretching, likely 500 to 1,000 miles southwest into the tropics and point that straight onto a exposed mountainous land and you’ve got a record-breaking rainfall set up…

More wind and rain to move in tomorrow as another Atlantic low moves onshore. I believe winds will be more notable this time around rather than the rains, however we can expect more heavy and persistent rains which will create more flooding probably.

More tomorrow,

Thanks for reading.

Today’s Weather Here
High 54 degrees and falling as system’s cold front pushes out Low 40s (no exact low due to not the usual diurnal patterns)

Heavy rains once again overnight, which turned to showers later in the morning. Skies cleared for a time during late morning and into early afternoon before more clouds and showers pushed in.. Tonight, skies clear out and blustry winds die down, allowing temps to drop close to freezing ahead of the next weather system tomorrow. The poential for frost in present tonight as lulls in between weather systems tend to allow the return to more classic diurnal temperature swings…
