[b]Last weeks highlights[/b]
Quite a cold week just gone, the coldest of what has been quite a mild Winter to date, however only a few areas saw much in the way of snow: hard frost across Wales last Sunday night lowest readings -7.6c Llanwnnen, -7.5c Sennybridge and -5.6c Trawsgoed followed by a lovely sunny Monday bar some wintry showers over Pembrokeshire ('Dangler'). The Midlands was colder on Monday night, many spots getting to -5c, including -5.2c at Coventry. Snow in places Tuesday into Wednesday. although WW missed this, even over the Midlands it was a fleeting affair, only the north of Nottinghamshire and Derbyshire seeing appreciable falls, the Peak District as so often getting locally deep accumulations of over 6 inches. A sharp frost Thursday night, especially parts of the Midlands, -6.8c Pershore and -6.1c Hereford. Friday did end up mild at above 9c over WW by evening. Overall it was a fairly dry week with precipitation amounts generally low (weekly totals under 10mm)).
[b]The week ahead[/b]
After the cold weather last week the start of this coming week is generally mild, and there will plenty of dry weather during Monday and Tuesday. Big changes from Wednesday however as we are plunged into a cold and quite windy NW flow bringing showers and some longer spells of wintry weather, most of us should have seen at least some snow come next weekend.
Sunday is a mostly cloudy and mild day, a few sunny intervals are possible, mainly Midlands. WW will be seeing a little rain or drizzle at times as the day progresses. Highs Sunday 9 to 11c, with a moderate SW breeze. Staying cloudy and mild tonight with a little light rain or drizzle at times, then with a band of more persistant and moderate rain affecting all parts later in the night. No lower than 7c excepting NW Wales where skies clear by dawn. Any rain clears the South Midlands by midday and with a ridge of high pressure over Ireland it should be a mostly dry afternoon with some sunshine. Sunny intervals from the off for most of WW, just the odd light shower possible here afternoon. Highs Monday 7 to 9c with a moderate to fresh NW breeze. Clear spells overnight leads to a fairly widespread but slight frost, minima between -1c and +2c inland.
The ridge is over sourthern Britain during Tuesday which is another largely dry day with sunny intervals and a brisk westerly breeze, highs 6 to 8c about average for the end of January. Probably clouding over during the afternoon for WW as fronts approach, these bringing a little rain or drizzle during the evening. Cloudy and mild for Tuesday night with rain at times, some heavy bursts for WW, and a strong SW to west wind. We will be in a warm sector on Tuesday night so one of those nights when it turns milder, temperatures up to around 10c after midnight. A pronounced cold front in total contrast swiftly moves through all parts during Wednesday morning with a band of heavy rain and gusty winds along it before it clears. Much colder air for Wednesday afternoon, sunny intervals and showers these turning increasingly wintry especially for high ground. Temperatures that were close to 10c at dawn Wednesday will be down to just 2 or 3c by mid afternoon! Feeling bitter in the fresh to strong WNW wind and by the end of the afternoon showers may well be falling as sleet or snow even to low levels. Remaining quite windy with wintry showers through Wednesday night too, most of the showers affecting WW, snow and hail featuring in these showers with a clap of thunder possible, and by morning there will be a covering of snow in places. In spite of the wind there will be a frost with temperatures down around -2c away from coasts.
By Thursday a large complex area of low pressure area has become situated between the UK and Scandinavia and controls our weather for the remainder of the week. Winds right through to the weekend predominantly coming from a cold NW to north direction and with the quite deep low so close by it will prove interesting weather too! A wintry mix of showers for Thursday then driven by a fresh west to NW wind, snow could fall in the showers virtually anywhere but more especially over hills, some heavy showers putting down a fresh covering - again this possible almost anywhere. Maxima of just 2 to 4c Thursday so a cold and wintry day! A longer spell of sleet or snow may move down from the NW later Thursday or during the night, and if so may give appreciable falls particularly to higher ground. A low may be centred over eastern England during Thursday night meaning lighter winds by this stage and so with clear intervals between the wintry showers a widespread frost will develop along with icy stretches, minima 0 to -3c.
A similarly cold and wintry picture seems likely for Friday too with low pressure just to our east and north, further showers or longer spells of sleet or snow, this settling particularly over high ground. Note: any snow accumulations to lower ground may well come and go as temperatures rise enough during day time to permit thawing, and in any case perhaps fewer showers getting across the Midlands with some places here having a mostly dry, bright day. Highs Friday between 2 and 5c with a cold NW wind. Next weekend and the cold and unsettled weather with showers and possibly a longer spell of wintry conditions looks like lasting. The details modelled vary obviously at this range ahead, but there is the risk of some more widespread snowfall at some stage next weekend as we remain locked into this cold pattern, no higher than 4 or 5c by day and there will be frosts by night. As with Friday WW most prone to wintry showers with the SE Midlands more sheltered and so may escape the worst.
