Drifts

Alvechurch amateur weatherman Phil Thomas records the changes.

March continued in the same pattern as February, with very cold temperatures. The 1st was an ice day (when the temperature stays below zero) with a maximum of –2.3C, followed by –1.0C on the 2nd and –0.3C on the 18th.

To get days like this in March is quite unusual in the Midlands. The middle of March turned much milder before temperatures plummeted on the night of the 16th, with further snow.     

March 2018 (to the 20th)
Mean Max 7.3C   2.5 below average

Mean     4.0C   2.1 below average
Rainfall     75.0mm   167% of average

February had only 28.1mm of rainfall, but a huge 102.2 hours of sunshine. However, daytime temperatures stayed low all month. Only one day reached double figures: 10.5C on the 19th.

The month was significantly colder than the local mean, with 13 air frosts and 23 ground frosts. On the 28th the air temperature only reached -1.2C.

February 2018

Mean     4.0C   0.2 below average
Rainfall   233.6mm 123% of average

Outlook
The cold spells of late February and March were due to Stratospheric Warming and a change in the Jet Stream. These winds from the east are commonly called “The Beast from the East”.

This pattern is rare these days but produces a very cold air stream and often snow and blizzards.

The further outlook in the coming weeks is for a colder or cooler than normal start to spring. Temperatures should gradually climb back towards the normal level – but this may also bring more changeable weather.
