A record high? (WS7 weather report 21-11-2017)

smalllogoOnce again we start the day with a wet footpath following some overnight rainfall in our area.

It is also going to be a breezy day with the synoptic charts showing that the points of similar air pressure are tightly packed in our area.  The average wind speed today will be around 10mph with gusts reaching around 25mph.  The wind will, however, be bringing with it mild air from the WSW.

At 06:30 hours the air temperature was already 12.9c.  Although we should not expect much variation from this for the remainder of the day (a top of 13.5-14c) the air temperature will very possibly beat the record for the day /area set in 2009 (13c).  Overnight we can expect the air temperature to reduce to no lower than 12c.

As the afternoon passes the rain radar forecast models are suggesting that a band of rain will push into our area by mid to late afternoon and will linger around during the evening.  The risk of some further rain today is around 80%.  The rain will eventually move away from our area around 03:00 hours.

Summary: An extremely mild start to the day.  Breezy with a risk of rain later.

Observations made on 21/11/2017 at 06:27 hours Hammerwich, Staffordshire.
Temperature : 12.8c; Air pressure : 1008.1mb reducing slowly; Relative humidity 91%; Wind : 14 mph WSW; Rain this month : 38.4mm; Rain this year : 512mm

Damp underfoot (WS7 weather report 20-11-2017)

smalllogoWe have received (by 06:30 hours) some early morning rain (1.8mm) in our area but the good news is that the bulk of the heaviest rain cloud is now beyond moving to the east.

There are some more, smaller, rain cloud formations that we will reach us around 10:00 hours and this system will bring a 40% risk of further rain.

The day will see the odd bright spell but will be generally cloudy.  The cloud will be at low and high heights.

It will be a mild day with a top temperature of around 12-13c.  Even overnight will remain mild with the low around 10-11c.

The mild air and occasional rain showers are entirely due to the warm SW-WSW air that we will be enjoying today.  It will, however, be breezy at times with the average wind speed around 7-8mph.

This evening / early overnight sees a 60% risk of further rain falling in our area.

Summary: A mild start to the day.  A risk of further light rain during the morning but then becoming dry with occasional bright spells.  Further rain likely later tonight / overnight.

Observations made on 20/11/2017 at 06:26 hours Hammerwich, Staffordshire.
Temperature : 9.5c; Air pressure : 1012.9mb reducing rapidly; Relative humidity 90%; Wind : 9 mph SW; Rain this month : 37.6mm; Rain this year : 511.2mm

The same as last year (WS7 weather report 19-11-2017)

smalllogoIt is a cold and slightly frosty start to the day. At 08:10 hours the air temperature was a lowly 1.3c.  By 08:21 hours, with the sun rising, the air temperature had leapt up to 1.6c! This is not dissimilar to the same day of the year last year when, at 08:21 hours, the air temperature was 2.1c.

Today will be cool but with some bright spells too.  Our top temperature will be around 8c and overnight the minimum temperature will be around 6c.

During the daylight hours of today the cloud cover will be generally thin but as we reach the later parts of the afternoon and overnight the cloud cover will thicken.

This thicker cloud will, eventually, bring some rain to our area.  The radar images are currently suggesting that we will have around a 80% risk of rain from around 02:00 hours.  (see image below).

Today’s breeze will be light and deriving from a SSW-W arc.  The average wind speed today will be around 4mph.

Summary: A cool start to the day with some frost around.  Some bright spells and dry.  A risk of rain overnight.

Observations made on 19/11/2017 at 08:20 hours Hammerwich, Staffordshire.
Temperature : 1.6c; Air pressure : 1023.5mb rising; Relative humidity 89%; Wind : 1 mph SSW; Rain this month : 35.8mm; Rain this year : 509.4mm

An average day (WS7 weather report 18-11-2017)

smalllogoThere is plenty of cloud cover around as I write this blog at (approximately) 08:30 hours.  The radar images, however, tell me we will see some odd brighter spells breaking through (the often) high to medium height cloud cover.

As my heading suggests today is going to be an average sort of day temperature wise for this time and day of the year.  Since I began keeping formal records in 2010 our average temperature at the time of my morning observations is 6.3c.  The lowest air temperature was 1.8c (at 08:42 hours so very similar timing) in 2012.  The highest early morning temperature was 9.8c in 2015.

Today’s top temperature will be around 8-9c and overnight our minimum temperature will be around 3c.

Today’s wind will be mostly deriving from a WSW-WNW arc.  Regular readers will be aware that this wind direction usually forms some cloud cover.  Today will be no exception.  The more northerly the wind direction the thinner the cloud will become.  The average wind speed today will be around 6-7mph.

The rain radar images are showing that there is rain to the west of our region but the current tracking does not suggest it will reach our area.  The risk of rain in our area is around 20%.

The next real risk of any rain for us is during late Sunday or the early hours of Monday when a widespread rain cloud system will move across the UK.  The current suggestion from the model is that the heaviest rain will fall to the north of us.

Summary: A mild but cloudy start to the day.  Some brighter spells will develop from time to time but, overall, mostly cloudy.

Temperature : 5.9c; Air pressure : 1021mb steady; Relative humidity 91%; Wind : 4 mph WSW; Rain this month : 35.8mm; Rain this year : 509.4mm

It’s cold outside! (WS7 weather report 17-11-2017)

smalllogoIt is certainly a cool start to the day with the air temperature at 06:30 hours only 2.3c.  The lowest temperature overnight was 1.8c at 05:17 hours.  Today’s low air temperature is in stark contrast to the same time yesterday when the air temperature was nearly 10c.

There is a ridge of high surface air pressure over our area today and although it will reduce from around 1029mb to 1024mb as the day passes there is only a 6% risk of any rain.  We will see plenty of bright spells with a bit of cloud cover particularly late afternoon.  The cloud will be at a medium height.

Our top temperature today will be around 7-8c but with the wind chill this will feel more like 4-5c.  Overnight the minimum temperature will be around 3c.

Today’s breeze will be deriving from a WSW-W arc.  The average wind speed will be around 5mph.  Gusts speeds could reach around 15mph.

Early next week should see a return to double-digit air temperatures and the odd drop of rain.

The weekend currently looks to be mostly dry with just a low risk of rain on saturday morning.

Summary: A cool start to the day.  Becoming brighter but still cool.

Observations made on 17/11/2017 at 06:30 hours Hammerwich, Staffordshire.
Temperature : 2.3c; Air pressure : 1018.9mb falling slowly; Relative humidity 89%; Wind : calm; Rain this month : 35.8mm; Rain this year : 509.4mm

Getting cooler today (WS7 weather report 16-11-2017)

smalllogoThere will be some air pressure and jet stream changes today that will bring some high surface air pressure to our area.

This high surface pressure will bring a clearer sky and lower air temperatures this evening.  The temperatures will be lower than those we have enjoyed more recently.

This morning will see cloud cover increase and the rain radar images are showing two clusters of rain that could bring some precipitation to our area.  The first will arrive just after 09:00 hours and bring a 25% risk of rain.  The second, late morning / lunchtime, will bring a 60% risk of rain.

Once these systems have passed the cloud will dissipate as the afternoon passes and the air temperature will reduce into mid to low single figures.  Our top temperature today will be around 11c and overnight the minimum temperature will be around 3c.  At 18:00 hours the air temperature will have reduced to around 5-6c.

Today’s breeze will be mainly from a WSW-WNW arc.  The average wind speed will be around 5mph.

Summary: A mild start with some risk of rain.  Becoming brighter and cooler later.

It was mild overnight (WS7 weather report 15-11-2017)

smalllogoBy the time of my observations (approx 06:15 hours) we had received some light rain in our area. The amount, however, was very small (below 0.2mm). The chance, today, of any further precipitation is only 18%.  There will, however, be a risk of some mist about.

It will, however, be a cloudy day with the cloud often at low and high heights.  Later today the cloud will thicken to encompass the full spectrum of low, medium and high heights.

The thicker cloud and an occasional SW breeze will help keep the day mild.  Our top temperature will be around 11c and overnight the minimum temperature will be around 8c.  (Last night’s minimum temperature was a very mild 8.6c at 04:25 hours).

Later today the air pressure will begin to reduce slightly and this will mean a slight increase in wind speed.  Overall, however, the wind will be light with an average speed of around 3-4mph.  The wind will b deriving from a SW to NW arc.

Summary: A cloudy day but remaining mild.

Observations made on 15/11/2017 at 06:17 hours Hammerwich, Staffordshire.
Temperature : 9.2c; Air pressure : 1023.2mb rising slowly; Relative humidity 89%; Wind : calm; Rain this month : 35.4mm; Rain this year : 509mm
