February 2016: average contrast

Though it was devoid of snowfall February 2016 was average for temperature and sunshine and on the dry side.

On the 15th cold northerly winds brought sharp showers to the coast. A big swell was seen at Broadstairs allowing for some good surfing conditions

Some sharp frosts made for a couple of stunningly sunny days, “ski resort weather” the kind of days that were absent during the first half of winter after the super mild December.

Rainfall of 35.1mm was 90% of average – the driest February for three years. Mean temperature for the month was 5.4C, 0.1C above the 1981-2010 mean.

Sunshine was just above average. Over 79 hours were recorded, 108% of what we can expect to see during an average February.

The wettest day occurred on the 7th with 11.6mm.

Air frosts: 10

Ground frosts: 16

So what has March got in store weatherwise? The late winter synoptic pattern could see the first snowfall above 1cm over the coming days and next week though amounts are likely to be small and temporary and restricted to night hours.

The pattern bringing this messy wintry mix is low pressure moving SE across the UK between now and the weekend each band bringing progressively colder air across the UK. Much of the precipitation will be showery although Friday looks more interesting as a secondary moving south brings cold N or NE winds. Models suggest next week will see high pressure from the west displacing this cold N. The timescale is very uncertain and it may be toward the second half of next week before the general theme of dry and settled conditions prevail. Frosts at night remain likely and daytime temperatures remain close to or a little below normal.

Overall the first half of March does not look like it will offer much in the way of spring weather.

My long range forecasting method suggests the most likely scenarios to be rather cold or cold, though both are only at 33% probability. Something average or below works out at 83% probability. The only mild indicator is for something rather mild at 16% probability.

A dryer than average month looks most likely at 66% probability. Something wetter than average works out at 34% probability.

Very dull conditions look most likely at 83% probability.

So to sum up: Mean: 5.9C, rainfall 31.6mm, sunshine 68 hours.

Taking all of the above into account perhaps the most likely scenario will be that the month will be predominantly anticyclonic with lots of gloom during the day and night frosts, varying in intensity.

So to sum up: Mean: 5.9C, rainfall 32mm, sunshine 67 hours.

My February outlook for temperature was good. I predicted a mean of 5.9C (outcome: 5.4C) with 31.6mm of rain (outcome: 35.1mm). Sunshine 68 hours (outcome: 79.5hrs)
