Air pressure change

Today has seen the overnight minimum temperature fall below 10c for the first time in a week.  Last night’s minimum temperature was 7.9c at 04:23 hours.  In 2013 we were in the middle of a very warm period with a temperature high on the 16th of 27.4c and an overnight low of 13.5c (around 70% warmer overnight in 2013 than it was overnight last night).

Today will see some bright spells through either fragmented or a thin cloud bed.  Low pressure will be pushing into our area from the W later today and this will help bring a risk of thunderstorms later this evening (as the day cools around 19:00 hours) and overnight.  During the daytime hours there is only an 11% risk of rain.  Overnight this increases to around 40%.  Our air pressure by 06:00 hours tomorrow will be around 1010mb.

Our top temperature today will be around 20c and the overnight low will be mild at around 13-14c.

The wind will start the day deriving from the NW but as the day passes the jet stream position will move to one from the W to E to the SW to NE.  This will help introduce the low pressure system to our area and also see the wind derivation to be from the E-ESE.  The average wind speed today will be around 6mph.

Summary : Bright spells through thin or fragmented cloud. A risk of rain and thunder later this evening with increased risk overnight.
