Breezy but not Doris (WS7weather report 25-2-2017)

smalllogo

As I write this blog (at approximately 08:15 hours) the air pressure is reducing rapidly.  A look at the synoptic charts show that, in our area, we are being affected by a low pressure system that is centred up above the NW of Scotland.

This low pressure system will “tighten” the points between areas of similar air pressure which, in turn, means it will be a breezy day.  By this I average winds speeds of around 12mph and nothing like those we encountered with Storm Doris the other day.  It will simply be breezy.

Couple with the breeze is a 60% risk of some rain from around 11:00 hours.  This band is clearly showing on the radar images this morning but, hopefully, it will have deposited most of its content before reaching our area.

It will be a mild and cloudy day due to the SW breeze.  The top temperature today will be around 9c and overnight will also remain mild with the thermometer low of around 7c.  It should be remembered that the wind chill (with a breeze of around 12mph) will reduce the feel of the air temperature by around 2.5c-3c.

Summary for today :A breezy day but mild.  A risk of some showers from late morning.

Observations made on 25/2/2017 at 08:08 hours Hammerwich, Staffordshire.
Temperature : 7.6c; Air pressure : 1009mb; Relative humidity  90%; Wind : 16 mph SW; Rain this month : 34.4mm; Rain this year : 85.2mm

After the storm (WS7weather report 24-2-2017)

smalllogo

Yesterday’s storm Doris is now beyond our area and it was pleasant to be able to hear the birds singing when I was making some of my observations this morning.  This was a far cry from yesterday’s roar of the wind.  As a matter of interest the top wind speed I recorded yesterday was 54mph at 09:36 hours.

To further demonstrate that the low pressure system is beyond our area is the rapidly increasing air pressure.  By mid afternoon the air pressure will be around 1016mb.

The early morning rain will generally be beyond our area by 07:00 hours and we can look forward to a bright morning.  The sun, breaking through, a fragmented cloud bed will help us reach a top temperature of 7c.  You will, however, find the commute to work a little chilly as the air temperature will only be around 4c. With the wind chill this will feel more like 2c.

During the afternoon the cloud bed will thicken and by late tonight there will be a 40% risk of rain.  Overnight the risk of rain is 80%.

It will still be a breezy day but nothing compared to yesterday.  The average wind speed will be around 6-8mph.  The wind will be deriving from the WSW for much of the day.

Summary for today : A cool start but some bright spells this morning.  Increasing cloud this afternoon will bring rain later tonight / overnight.

Observations made on 24/2/2017 at 06:36 hours Hammerwich, Staffordshire.
Temperature : 2.7c; Air pressure : 1013.3mb; Relative humidity  91%; Wind : 4 mph WSW; Rain this month : 32.8mm; Rain this year : 83.6mm

Storm Doris reaches Hammerwich (WS7weather report 23-2-2017)

smalllogo

The much talked about (in the press at least) Storm Doris reaches our area today and as you step out to go to work this morning you are likely to encounter a gusty breeze and some occasional rain showers.

The showers will be heavy at times but the good news is that the radar images are showing that there is a gap when the rain will either stop or become light during the peak commute time of around 08:00 to 09:00 hours.   We will see, however, more rain showers today with the risk of further rain at 95%.

The day will become very blustery particularly around mid day when the isobars are at their closest but as the daylight hours finish the wind speeds will begin to reduce.  The clouds will also begin to thin as the evening passes.

During the commuting hours our average WSW-W wind speed will be around 17mph will gusts of around 30mph. As the morning passes the average wind speed will increase to around 30mph by lunchtime with gusts speeds reaching around 50mph.  The wind will be deriving from W-NW by this time.  AS the day ends and evening begins we will see a reduction in wind speed back to an average of around 8-10mph.

Our top temperature of the day of 9.3c was at 06:30 hours this morning and by lunchtime we can expect the air temperature to only be around 5-6c.  With the wind chill this will feel more like -1c.  Overnight the minimum temperature will be around 2-3c.

.Summary for today : A windy day with some heavy showers.  feeling very cool with the wind chill and reducing air temperature.

Observations made on 23/2/2017 at 06:30 hours Hammerwich, Staffordshire.
Temperature : 9.3c; Air pressure : 987.1mb; Relative humidity  89%; Wind : 17 mph WSW; Rain this month : 29.4mm; Rain this year : 80.2mm

A breezy day (WS7weather report 22-2-2017)

smalllogo

It is a breezy start to the morning and these increased wind speeds will remain with us for much of the daylight hours.  The average wind speed will be around 10mph with gusts of 25-30mph.

The wind will be deriving from a WSW-WNW arc for most of the day.

It will be another mild day.  The air temperature at 06:40 hours was already at 11c.  Whilst this figure will not increase by much as the day passes this is still very mild for the time of year.  The overnight minimum temperature will be around 8c.

The radar images are showing that there is plenty of rain cloud around today although the bulk of the early morning rain is to the north and west of our area.  If you travel up to the Derby area though you are fairly certain of seeing some early morning rain.

We are, however, unlikely to remain all day given that there will be plenty of rain cloud passing our way as the day passes.  The risk of some rain during today and/or in the early hours of tomorrow is around 85%.

.Summary for today : A breezy day but mild.  A high risk of some rain showers.

Observations made on 22/2/2017 at 06:40 hours Hammerwich, Staffordshire.
Temperature : 11.2c; Air pressure : 1005.1mb; Relative humidity  87%; Wind : 9 mph WSW; Rain this month : 23mm; Rain this year : 73.8mm

Reducing air pressure (WS7weather report 21-2-2017)

smalllogo

It is another mild start to the day with the air temperature at 06:30 hours already at 10c.  Thursday and Friday this week will see a slight reduction to these high temperatures with the  overnight / early morning commute air temperature around 3-4c.

The radar images also show that there are some light rain clouds around our area today (particularly first thing this morning and during the afternoon) and these clouds bring a 40% risk of some rain  in our area.  In general, however, the day will be cloudy and mild.

The top temperature of the day will only be around 11-12c and the overnight low will be around 9c.

The air pressure will be reducing as the day passes and will end the day around 1005mb.  The steady change in air pressure will bring an increase in the wind speed this afternoon.

The average wind speed this morning will be around 4-5mph but this afternoon will see an increase to the average speed to around 10mph with gusts of around 20-25mph.  The wind will be deriving from the WSW.

.Summary for today : A mild but cloudy day.  Increasing wind speeds during the afternoon.

Observations made on 21/2/2017 at 06:35 hours Hammerwich, Staffordshire.
Temperature : 10c; Air pressure : 1005mb; Relative humidity  90%; Wind : 4 mph WSW; Rain this month : 22.4mm; Rain this year : 73.2mm

How warm? (WS7weather report 20-2-2017)

smalllogo

It will be a very mild air temperature that greets you as you make your journey to work and those of you that are on half term holiday will certainly have a warmer than normal first day of your February half termholiday.

Our top temperature today will be around 13c and overnight we again will remain mild at around 9c.  Last night’s minimum temperature was 10.1c at 00:00 hours.

I cannot, however, promise too much in the way of sunshine as the mild WSW  wind will be developing plenty of clouds.  This cloud will not bring too much threat of rain during daylight hours (14% risk of rain) but we will see an increased risk after dark (40% risk of rain).  The biggest risk of rain (75%) will be in the early hours of tomorrow morning and it is possible that some rain will be lingering around as we commute to work on Tuesday.

The wind will be averaging  a speed of around 7mph and will be deriving, for the majority of the day, from the WSW-W.

.Summary for today : A warm day for the time of year but mostly cloudy.

Observations made on 20/2/2017 at 06:31 hours Hammerwich, Staffordshire.
Temperature : 11.3c; Air pressure : 1017.5mb; Relative humidity  90%; Wind : 6 mph WSW; Rain this month : 22.4mm; Rain this year : 73.2mm
