If you just looked at the statistics this month you would have thought it has been a warm month. But it has felt much colder with a few snow events. The temperatures at night haven’t been that low which is why the statistics have come out as milder than average. The final CET for England has come out at 5.26c which is 1.5c above normal.

Here in Watford we only had 5 air frosts and only 10 dry days, more stats below.

Looking ahead to February

The first week of February is looking cold with frequent out breaks of snow. It will feel much colder as we will be on the cold side of the jet stream. Looking further ahead there will be further brief mild interludes when the Altantic tries to break through the block to our east. Could be lots of fun with snow or cold rain.
