A guess of 6.7*C and 42mm please.

Probably mostly High Pressure dominated with variable cool and mild days. Nights being chilly and misty with some frost at times. A gradual return of unsettled conditions from the West around 2 thirds into the month, perhaps preceded by snow over Northern high ground, but High Pressure quickly building back centred over Northern UK. Pressure maybe low enough to the South to bring in some light wintry showers from the East over South-Eastern areas at times.

Exceptionally dry Novembers (EWP) are rare beasts and compared to other months they are not that exceptionally dry 

Top 10 driest Novembers' average: 31.9mm

Compared to the average of the other top 10 driest for the rest of the months

January: 19.8mm

February: 10.7mm

March: 12.4mm

April: 10.1mm

May: 16.4mm

June: 15.3mm

July: 20.1mm

August: 20.5mm

September: 16.5mm

October: 21.9mm

December: 20.2mm

Driest November is 1945 with 17.0mm and there have been 3 drier months this decade than this: April 2011, September 2014 and June 2018
