Exceptionally wet, mild

 

This was one of the wettest Februaries locally on record, 213mm of the total falling in the first half, with a drier but nonetheless wet second half. It was the wettest of any month since November 2009 (309mm). It was the third successive month above 200mm. As with the whole of Winter 2014 there was a total absence of hard frosts or significant wintriness with no lying snow and only occasional falling sleet. Although a mild month there was no really mild weather the highest readings of the month being 10.4c (18^th and 27th).

 

1^st – 14^th: Very disturbed, exceptionally wet and with strong winds. A succession of deep lows crossed the UK through this period, bringing unusually low pressure, it got down below 970mbar on 3 separate occasions, and with the months lowest pressure of 963mbar 14^th. Frequent bouts of heavy rain, 9 days in this fortnight over 10mm, 5 over 20mm and 3 over 25mm, with the wettest day of the month being 32.2mm 14^th.

Relatively a much drier period with more 'normal' unsettled conditions, and lows now tracking north of the UK. Still, most days saw at least a little rain, but amounts much lower, and the wettest day in this spell saw only 13.8mm (17^th). Sunny intervals with the 16^th being a nice sunny day. Maxima getting above 10c at times although there were a few more slight frosts, the lowest reading of the month being -1.9c on the 16^th.

February 2014 Statistics

February was a month that was fairly benign from those that preceded them, except for one final storm around Valentines Day and the snow snowfall of the season that occurred on the 11th, however the snow did not settled and it only lasted around 5 minutes. There was a fair bit of rain, without it being nearly as wet as January. Again this month will be noted for the absence of air frost, which has been the big headline hitter along with the rain and wind this Winter.

HOBART is Australia's southern most city situated at sealevel at the base of Mt.Wellington (1270m). Climate maritime temperate.

 

February - Final month of summer

A destructive squall line ahead of a cool change on the 9th caused widespread minor damage around Hobart. The peak wind speed of 130km/81mph was the highest ever recorded for February and the highest for any season since winter 1991. Trees and power lines came down. A motorist lost his life when a falling tree crashed down on his moving vehicle. What are the chances.

 

Daily maximum temperatures jumped around a bit from day to day but were chiefly in the range of  high teens to mid 20s. Two days exceeded 30C, close to average. A tropical depression eventually reached Tasmanian latitudes on the 15th producing overnight thundery showers ( 19mm) making it the wettest day of the summer. Otherwise, weak fronts brought an occasional shower or two, or a brief drizzle period. Summer was more warmer ( mean +0.7C ) and drier ( 54% of average ) than normal. Temperature anomaly based on 1981-2010 values.

 

Average maximum:  23.1 ( +1.0 )

Average minimum:  13.0  ( +0.4 )

Rainfall:  28mm ( average 41mm )

Rain days ( +1mm );  5/from 9

The joint mildest February since 2002. The month was completely snowless for the first time in 27 years of snowfall records. It also marked the end of the first snowless winter on record. The month continued the trend of the winter of seeing close to average rainfall and above average sunshine. Indeed, it was the sunniest February since 2008. Nevertheless, the month was still very unsettled with frequent wind and rain. The highest gust of 53mph seen on the 12th was the highest recorded at this site since I got my Davis. The mean sea level pressure was 992.9hPa, a new record low. Winds were consistently within 90 degrees of south meaning it was mild almost without fail. Despite this, there was a marked difference between the first and second halves of the month. The first half had a mean of 5.9C and 36.8mm of rain, but the second half was much milder and drier with a mean of 7.4C and a total of just 9.0mm of rain.

 

Overall another very disappointing month for winter weather, finishing off a completely snowless winter, but still containing some interesting weather.

My statistics for central Reading in February 2014:Average maximum: 10.2Average minimum:3.8Average for month: 7.0Highest maximum: 19.1 (Feb 20)Lowest maximum: 7.2 (13)Highest minimum: 8.7 (23)Lowest minimum: 0.1 (16)Air frosts: none

Sleet/snow: noneRainfall: no data available for this site; Reading University shows around 140mm for the month, which is around 350% of average, so a very wet month again.  The only 24 hour period with no rainfall was on the 16th.

 

A continuation of more of the same here - very mild and exceptionally wet, with frequent depressions bringing a the rainfall total similar to January's.  Another month with an exceptionally large number of wet days - 1.0mm or more was recorded on 24 days out of 28.  A further notable statistic was the lack of any air frosts, exceptional considering that February is the month of the year with on average the coldest night time minima.

...the maximum on 20 February here was 13.8, not as shown.  As you probably guessed, it wasn't my thermometer that suffered a hiccup, it was my typing .   When I get time I hope to put up a short summary of the winter statistics here in Reading.
