[font=arial][size=3][b]Last weeks highlights[/b][/size][/font]
[font=arial][size=3]Very mild with some rain and drizzle up to last Tuesday night, Snowdonia receiving several inches of rain over a couple of days, although only a little rain for most of the Midlands. 13 or 14c reached in places both Monday and Tuesday with nights staying in double figures too, notably mild for late December due to air of Tropical origin. A cold front brought cooler though not especially cold weather on Christmas Eve which lasted through to Boxing Day giving some slight frosts making it feel more Seasonal. Much of the north Midlands had a snowfall on Friday evening, worst over the Derbyshire peaks where up to one foot fell, for most though no more than a brief fall and temporary covering. In contrast at the same time a mild sector passed over SW Wales and the south Midlands during Friday evening, 11c reached across Pembrokeshire at the same time Derbyshire was very snowy! This weekend has been quite cold too with wintry showers for many areas and further night frost and ice. Temperatures Saturday night as low as -4c in places such as Llanwnnen.[/size][/font]
[font=arial][size=3][b]The week ahead[/b][/size][/font]
[font=arial][size=3]This week will see plenty of dry and cold weather with frosty nights as an anticyclone crosses southern UK. More unsettled to end the week with some rain or showers at times but still quite a bit of dry weather. Sunday morning is frosty, with shade frost persisting for many all day, high pressure over Ireland feeding down rather cold northerly winds. Mostly sunny for Sunday highs 4 to 6c, below average. More of the same really through to New Years Eve with the anticyclone transferring SE across southern UK and into the Continent. A chilly but dry 3 or 4 days to come seeing out 2014, sharp frosts and foggy in places by night, but for many some sunshine by day. However some areas of fog will stick into afternoons some days locally, where this happens temperatures not getting above zero, generally though maxima in the 3 to 5c range, and milder along west Wales coasts. As mentioned, quite hard frosts to come until mid week, widely getting down between -2 and -4c, with lowest readings of -6 or -7c possibly for usual spots. [/size][/font]
[font=arial][size=3]Changes underway as we go through New Years Eve as the high recedes into the Continent, and a SW flow becomes established across northern and western UK. For most though a similar picture of dry bright chilly weather after frost on Wednesday, fog persistent over parts of the Midlands. It should be dry in most places for the New Year festivities except perhaps for NW Wales where a little light rain or drizzle may arrive by midnight. Milder on Wednesday night across WW but another frost likely for the Midlands. Uncertainties on the extent and nature of the breakdown for later in the week, but it turns milder and more unsettled during New Years Day into Friday as SW winds sweep across all areas. Maxima by this stage between 8 and 11c, mildest out west, rain at times but still some dry conditions at times too. [/size][/font]
[font=arial][size=3]Next weekend and the weather looks changeable, we may well see a temporary ridge at some stage giving a dry cold interlude, but on the whole rather unsettled with some further rain or showers about, these wintry especially over hills.[/size][/font]
