Coldest Night of the Year

Dawn on Sunday morning produced our lowest temperature of the year as the thermometer plunged to -5.2°C or 22.6°F.
Temperature Records 01-03 February 2019
It's not quite the lowest temperature I've recorded in February, that record is still held by 11-February 2012 with -5.9°C or 21.4°F. However, it's still cold enough to move it into my list of top twenty lowest temperature since 2010.
Top Twenty Lowest Temperatures Since 2010
A few weeks ago I compared a couple of weather model outputs to show just how much the output could vary over a 10 day period. It's worth a quick look at this morning's output for the GFS and GEM models especially regarding the low overnight temperatures.
GFS (Top) and GEM (Bottom) Output for 03-05 February 2019
Whilst neither model has accurately modelled the temperature, at least the GEM suggests something rather unusual. The GFS model suggests nothing other than a slight frost, nothing out of the ordinary for a February night. The GEM is suggesting another cold night Monday into Tuesday, so it will be interesting to see if it continues this trend over the next day or so as the output updates.
Our newly purchased seed potatoes will be staying bagged up in the garage, hopefully protected from the cold temperatures, rather than moving into our unheated greenhouse to chit. There will be plenty of time for them to chit before planting time if they move into the greenhouse in March.

  1. Odd to me that January appears only once in that list of coldest nights.

    1. That got me worried. Had I missed some cold January nights off the list. I had a check of the January low temperatures and there is indeed only the one low temperature in the list. We've had some cold spells in January with temperatures around the 24°F mark for several nights in a row but missing the exceptionally low values.

      The weather turned milder so hopefully no more frosty nights for a few days.
