Tideswell, Derbyshire – Friday 20th April 2018

1600z 29007kt 30km SKC 17.3/08.1 1023
RMK: It remained rather cloudy till around midday with only
occasional sunny intervals. Through the afternoon the
cloud gradually dispersed and it has become increasingly
sunny. We now have wall-to-wall blue sky, deep blue overhead
and a little bit hazy-looking around the horizon. Max
temp 17.6° so, at least for me, it’s been a very much more
pleasant day than the excessive heat of yesterday.

0900z 28007kt 10km 6St007 11.4/9.9 1023
RMK: The fog lifted around 0630z but the stratus is proving to
be much more stubborn. The base has slowly risen but it has
broken only sufficiently to allow a few brief sunny intervals.
It’s a much cooler morning than yesterday with today’s 0900z
temperature being 7.0° lower than yesterday’s.

outside of my comfort zone. With a max temp of 25.1° it’s
been, by some margin, the hottest April day in the 10 years
that we have been here. The previous highest was 21.9° in
2015 and in 2011, both on the 23rd.

cloud then slowly broke up and dispersed and it has become
increasingly sunny. A very warm and muggy afternoon with

this year.

Tideswell, Derbyshire – Wednesday 11th April 2018

1600z 01007kt 0150 -DZ FG VV/// 05.4/05.2 1009
RMK: Drizzle and fog all day. The vis improved to 400m for a
time in early afternoon but it’s as thick as ever now with vis
down to 100m at times. With a max temp of 5.4° and a gusty
breeze it has felt decidedly raw. It’s one of the nastiest
faces of spring. There’s even some snowdrops still in bloom,
adding to the February feel and look. I still don’t understand
why fog as thick as this doesn’t trigger a severe weather
warning. Fog is fog, no matter what the mechanism is for
its formation. Attempting to drive at 60 m.p.h. on the main
roads through the area at present would be foolhardy.

0900z 01009g29kt 0250 -DZ FG VV/// 04.5/04.4 1009
RMK: A thoroughly unpleasant, raw morning. There was some
slight rain mixed in with the drizzle 0715-0745z but it’s back
to drizzle only again. It looks like progressively colder
air has been advecting in during the morning. The temp was
6.9° at 0145z It then fell steadily to 6.0° at 0400z then
flat-lined at 6.0° till 0515z. After that it fell quite quickly
to 5.0° to 0620z then more slowly to the present value of 4.5°.

1600z 06005kt 0300 -DZ FG VV/// 06.3/06.1 1005
RMK: The perfect activity today would have been to curl up
in front of a log fire with a good book. I spent the day in
front of a computer screen, which was probably a good
second-best! The rain ceased by 1000z but was immediately
replaced by slight drizzle. At the same time, the cloud base
lowered to ground level. We’ve been in fog ever since with
the vis mostly in the range 200-400m. There’s been slight
drizzle for much of the time and a decidedly raw breeze
which was gusting 25-30 knots 0800-1100z. Max temp only 6.4°.

0900z 34009g25kt 4000 -RA 7St004 04.9/04.5 1002
RMK: The rain is slowly easing but it remains gloomy, bleak
and raw. The statistics show just how dull and wet it has
been in recent weeks. With 30% of April gone we have already
had 107% of the average rainfall for the whole month but
only 16% of the average sunshine for the whole month. 43% of
spring has now elapsed. In that period the rainfall total
is 93% of the average for the whole of spring while the
sunshine total is only 18% of the average for the whole of
spring. Dull and wet sums up the first half of spring very
well. It has also been cold.

such conditions here. The first 4 days of the month have
produced 80% of the average rainfall for the whole month but

Tideswell, Derbyshire – Monday 2nd April 2018

1600z 35002kt 0400 RA FG 8St001 +02.8/+02.5 992
RMK: It must be a Bank Holiday Monday! There was a dry spell
for a couple of hours in mid-afternoon but the rain is back.
There’s been fog on and off since mid-morning. There’s still
2-3cm of lying snow with a 90% cover. The roads around the
village have only a little slush on them and are no problem.
All the high-level main roads are now open after many were
closed earlier in the day. Max temp 2.8° so far. A thoroughly
foul day.

RMK: Moderate sleet started just after 2200z yesterday evening
with the temp on +2.0°. Judging from the temperature trace
and the time the AWS stopped clocking up rainfall I reckon
the sleet probably turned to snow around 0300z. There’s
5cm of lying snow on all surfaces, including the road. There’s
no drifting. The temp is slowly creeping down.
