Watching the jet stream

Today will see the last, for a few days, of the generally dry, bright and mild weather as, within 36 hours, the jet stream will be firmly “looping” towards the south. This means that the cool air to the north can “mix” with the warmer air from the south forming clouds and rain.  The jet stream will then “push” this cloud and rain mixture across our region over the next few days.

Today, however, will be a dry day with only a 10% chance of any rain in our area.  The cloud cover will eventually fragment to leave us with some bright spells and a top temperature of around 15-16c.  The overnight low will be around 5c.  There is good news for our astronomers too as we should see some clear spells for them to make observations.

The isobar maps show that the air pressure points are fairly close together which indicates that it will be, at times, breezy.  The average wind speed will be around 9-10mph with gust speeds up to 20-25mph.  The wind will be deriving from the SW.
