Forecast for today.
Today is the start of a wintry spell of weather that will take us out of this month and into February.
There are a few things to note about the observations made.
Firstly, the air pressure is rising which means that for today we will have less cloud and some clear spells. This will allow some sun to shine through. The lack of cloud and the distant winter sun will, however, not be sufficient to bring the top temperature much above 6c. Overnight without the cloud duvet to keep in the residual heat the temperature will fall to around 0c.
The jet stream (see image below) and the low level wind direction are both coming from a generally northerly direction. This will bringing cold winds with an average speed of around 5mph during the daylight hours. This extra wind chill will turn our thermometer temperature of 6c into one feeling more like 3c.
The relative humidity is high and as temperature fall during the night we could expect to see some fog when the temperature reaches dew point.
Over the next few days some wintry showers will reach our patch following a wind shift to the east on Sunday. This means that early next week we could see some snow mixed in with the rain that is moving across our area late Sunday / early Monday. One reader of this blog @tcstretcher will be delighted to hear this news. For many others it is not such good news.
Cold with some bright spells.
