February 2019 – Historically warm after a freezing start

February started very cold, with the first 3 days averaging below freezing. Rain was plentiful until the 9th, but then the dry weather of February returned, accompanied by increasingly warm unseasonal temperatures.

The airstream was coming from the Canary Islands. The all-time February record was smashed in England and Wales on 26th and 27th, topping 20 degC for the first time in a winter month.

Here at my site in Durham, the maximum got to 17.1 degC on 26th, which is a very close to the February record at Durham Observatory, 17.4 degC observed on the 28th February 2012. I wait with baited breath to see whether that has been beaten.

Temperatures returned to normal for the last day, the maximum dropping 10 degrees from 27th. The average for the month was 6.3 degC based on hourly values, and 6.8 deg on the more traditional (max+min)/2 method of calculation. This made February 2018 very warm.

The rainfall total was below average again – only 33.6mm in total, with the two wettest days being the 7th (8.7mm) and the 3rd (6.6mm).

Monthly Report – January 2019

The New Year opened much the same as the old one ended, with dry benign weather and extraordinarily persistent High Pressure for the first half of the month. The high was a cloudy one, so temperatures stayed above freezing, with no fog or frost. It’s very unusual for a January to have such a high average pressure and not be cold and frosty.

Alarmist headlines were again plentiful in the tabloids, with lots of doom laden promises of snow-bombs and Polar vortices, the writers not really having a ‘scooby’ what they were writing about. All done to generate paper sales.

By 17th we got a strong Northerly flow and this drove snow showers inland along areas exposed to the wind. A slight covering of snow resulted.

Conditions continued generally cold in the second half, with the coldest weather reserved for the final day. Temperatures fell overnight 30th/31st to -5.9 degC, which is pretty impressive without any snow cover. The snow did arrive the following night though, with a 2″ powdery covering going into February.

Mean temperature for the month was 4.1 degC, which is slightly above the long term average for January (3.8). There were 10 days with air frost altogether.

The low level of rainfall was remarkable for a January total. 10.1mm is about 20% of what is normally expected here.

Heavy snow in Durham – “The Beast from The East” March 2018

An Easterly outbreak, dubbed “The Beast from The East” by the media, dumped a substantial amount of snow on us at the end of February and early March 2018. Here’s a view across The River Wear from the path just as we emerged from Pelaw Wood.

Nacreous Clouds over Durham, Feb 2016

A fantastic display of nacreous (mother of pearl) clouds occured across NE England in February 2016. These photos were taken above Durham Cathedral and Castle at about 7:15am.

Nacreous Clouds are quite rare. They can glow very brightly due to iridescence and are much higher than other tropospheric clouds, a height of 15-30km above the ground is typical. They are caused by wave-like motion of air, normally due to the proximity of mountain ranges. Best viewing is just before dawn and just after sunset.
