November 2006 - Weather Summaries

[Andy Bown]

The month got off to a beautiful, sunny and cold start, then was dominated by very wet, windy and mild conditions.

For Westbury, Wiltshire

Average max = 10.76c (highest = 14c on 8th, 13th, 14th, 23rd)

Average min = 4.66c (lowest = -4c on 3rd, also 3 x -3c mins)

Mean = 7.71c (0.71c above 4 year November mean)

Dry days = 13

Precip days = 17 (of which sleet/hail = 1)

Rainfall = 147mm (nothing in first 10 days! and 2 and a half times last November's amount)

Had it not been for the cold, frosty start to the month the mean temperature would have been higher. If I discount the opening 3 days (of 7c maxxes and -3c/-4c mins) the mean for the other 27 days is 8.38c.

November 2006 Report.

By Paul Carfoot.

The beginning of November saw a cool north-westerly air stream affecting the country, this was to be a very brief affair however as high pressure quickly became established, this had the effect of trapping the cool air over the country, so from the 1st onwards for the next few days, frost was widespread at night. Here in Burton I recorded the first frost of the season on the evening of the 1st.

The rather cool settled weather with frost at night continued until the 4th.

The 5th saw the high which had given the settled cool conditions move SE in to Europe, this had the effect of turning the winds to a mild southerly, and with sunshine temperatures quickly returned to above average, although night time temperatures were still on the cool side with ground frosts recorded here in Burton on the 6th, 7th and 10th.

Later on the 10th the Euro high gave ground and allowed low pressure to approach from the west, this herald the most unsettled zonal spell of weather for over 12 months, with strong winds and rain at times, temperatures were mild at first, but as each low tracked a little further south, temperatures gradually fell to the November normal or a little below. Ground frost was again recorded on the night of the 18th under clear skies and an air frost on the night of the 19th when the air temperatures fell a little below freezing.

The 19th to the 24th continued with the very unsettled theme with plenty of rain as areas of low pressure continued to feed in off a very active Atlantic, however temperatures began to get back in to the mild category as winds came from a more southerly source.

The 24th until the end of the month continued with the very unsettled zonal type weather conditions, temperatures continued to be very much on the mild side here in Burton, although one or two nights gave some fairly low temperatures considering the very mild air source, the night of the 29th being notable, I recorded an air minimum of 3.6c during a brief clear slot in the weather.

Summary.

A rather dry start to November with below average temperatures as high pressure was close by.

However around the 10th of the month, a big change took place as the Atlantic came to back to life after seemingly laying dormant for the last 12 to 18 months. The rest of the month was unsettled and very mild.

Stats below are calculated using the average of the mean monthly maximum and the mean monthly minimum.

Average maximum temperature = 11.1c

Average minimum temperature = 4.1c

Mean temperature = 7.6c + 0.7c above the 1971 – 2000 CET average.

Warmest day on the 16th = 14.7c

Coldest day on the 22nd = 7.1c

Warmest night on the 15th = 10.9c

Coldest night on the 3rd = -3.6c

Ground Frosts = 3

Air frost = 6

Thunderstorms = 0

Wettest day on the 22nd = 9mm

Rainfall total = 41mm

Year total rainfall so far 447mm

[Thundery wintry showers]

November 2006 Stats for Cleadon: (Note: 1971-2000 temperature averages are estimated, based on the averages maps on the Met Office website)

Max Temp 11.1 (+1. :blush:

Min Temp 5.1 (+1.0)

Mean Temp 8.1 (+1.4)

Highest max: 13.9 (13th)

Lowest min: 0.1 (3rd)

There were no days with thunder, hail, sleet/snow, or fog. The closest I got was on the evening of the 17th, when rain fell at a temperature just under 3C, and snow showers were reported on high ground in Durham.

Precipitation: 25mm

It was a dry and sunny November. The first half of November was anticyclonic and comparably sunny to the second half of November 2005, with temperatures close to average (warm days but cold nights). The second half was unsettled and mild, with a similar mean temperature to the first half. Although it was unsettled, rain didn't amount to much, and the weather was frequently of the "sunshine and showers" variety, enabling sunshine to continue a little above normal.

Overall, it wasn't quite as sunny as last November, but it was probably one of the few sunniest in the last 100 years. It was the mildest since 2003 (which was only 0.1C warmer; the last significantly warmer November was in 1997), and the driest since 2004. There were no air frosts, for the first time in November since 2000. The remarkable homogeneity of the warmth of Autumn 2006 continued for another month, though it wasn't as anomalously warm as Sep and Oct.

I'm pretty certain that here in the North East, 2006 is going to be a record warm year, beating the previous record-holders of 1990 and 2003.

Apart from the initial rather cold spell with night frost, generally a very mild month. One quirk is that I recorded a maximum of 13.2 on four days in succession (23-26). Maxima were generally very consistent in the second half of the month (mostly in the range 11-13).

After a cool first 4 days it was a uniformly mild month without a single air frost, the first such November since 2002. The first week was settled and dry with some sunshine, but it quickly turned more unsettled with a combination of mild days and exceptionally mild nights. Suprisingly in such a zonal setup, the month turned out below average with regards to rainfall overall, though was rather sunny. There were also a lack of exceptionally mild days above 15°C and nights in double figures. The month was also completely devoid of thunderstorms and not suprisingly, snowfall.
