HP brings a very mild but often cloudy airflow from the SW for 1st to 3rd. Airflow becomes more mobile and westerly, some brief, light drizzle late evening of 5th but not measurable. 6th is clear and sunny.
8th - 13th
LP "Tilo" crossing Orkney/Shetland brings stormy weather to far N. Cold front with squall line passes here late pm of 8th bringing brief downpour. Tilo moves slowly across southern Scandinavia leaving the UK in a Nly but not cold airflow. HP to the NW of Ireland by the 12th. Light rain early am of 13th.
14th - 17th
HP settles over the southern UK, feeling rather cooler with ground frost on 15th and 16th then hazy sunshine all day 16th.

18th - 22nd

LP drifts slowly in from the SW bringing snow to the Midlands as milder air meets colder air. Rain here on 18th late pm and evening with a little sleet for a while here before temperature rises, followed by more rain showers during the day on the 19th and more persistent rain later. Milder and continuing unsettled with outbreaks of light rain as LP continues to drift eastwards along the channel.

23rd - 30th

Ridge of HP over Ireland and W Scotland. Clearance of cold front overnight. 23rd is a sunny day with a cool breeze. Weak fronts bring much cloud but no rain 24th and 25th.

‡ SUN: Sunshine hours are calculated approximately and solely from solar radiation readings, but note that the solar sensor's exposure to sunshine is limited. The sensor receives only 50% of total possible sunshine exposure this month due to obstruction. There is no allowance for sunshine by visual observation only, so the sunniest day figures above can be very significantly less than the actual daily sunshine duration.
THW = Shaded Heat Index calculated with cooling/warming effect of wind and humidity to give an apparent temperature.
THSW = Unshaded Heat Index calculated with cooling/warming effect of wind, humidity and full direct sunshine to give an apparent temperature.
EVAPO-TRANSPIRATION is drying effect due to sun and wind, and is equivalent to "negative rainfall"
