10 February 2012 – A day with snow?

Today will not be a great day for a walk or cycle unless you like wearing waterproof wellingtons and clothing.  Already (at 08:55 hours) we have had 3.4mm of rain to fall and more will follow as the day passes.  Like yesterday the consistent cloud cover will also mean that it will be another dull day.

We are currently sitting a low pressure dominated by colder winds from the NE.  As the day passes the jet stream will bring warmer but weather weather from the NW.  This will initially increase the rain fall rate with the heaviest rain falling between 15:00 and 18:00 hours.  During the later part the rain will begin to fall as sleet.  During the later part of the heavier period of rain some sleet is likely.

Our top temperature today will be around 4c and the minimum overnight will be around 0c.  The wind will be blowing from ENE at an average speed of 7mph with gusts up to 20mph by mid afternoon today.  This will add some wind chill to the temperature and, as we need the temperature at 1.5m from ground level to be at -5c or less for snow, then the conditions may just reach optimum for snow.

The conditions are only currently around 80% perfect for snow later this evening but the indications on all of the ensemble models strongly suggest that snow conditions will form fully by around 20:00 -21:00 hours when will see any previous sleet begin to fall more consistently as snow.   I will keep this situation updated on twitter via @WS7weather.


Rain for the majority of the day sleet and snow likely later.
