[color=rgb(0,0,0)][font=Helvetica][color=rgb(28,40,55)][font=arial][b]Headline: Cool, sunny intervals and hit and miss showers; drying weekend but perhaps wet Bank Holiday Monday[/b][/font][/color][/font][/color]

[color=rgb(0,0,0)][font=Helvetica][color=rgb(28,40,55)][font=arial]The past week was a cool and showery one, as always in these showery set ups, some places saw torrential downpours and thunder while others missed the worst. [/font][/color]Downpours and thunderstorms were quite widespread on Thursday, here at Llanwnnen 10mm fell in just 15 minutes on Thursday morning, with a maximum rain rate of 123mm/ hour briefly, while [color=rgb(28,40,55)][font=arial]45mm fell in 24 hours Thursday at Swyddfynnon, Ceredigion. In contrast Valley on Anglesey collected just 0.2mm Monday to Saturday inclusive while quite a few spots missed the worst of the showers after Monday. [/font][/color]A rather cool week past overall, especially for Cardigan Bay and NW Wales where some days did not exceed 17c. The Midlands and SW Wales fared rather better in the temperature stakes, much of the Midlands managing 19 to 21c and so closer to average on some days. Wellesbourne 21.1c on Wednesday being highest reading of the week across our regions, however on the same day Capel Curig in Snowdonia did not better a miserable 15c! Cool nights in the second half of the week, Bala 3.7c, Trawsgoed 5.4c Thursday night lows, then Friday night down to 5.9c here at Llanwnnen, and 6.1c Pembrey Sands. [/font][/color]

[color=rgb(0,0,0)][font=Helvetica]Another essentially cool and showery week to come, as ever showers hit and miss - some areas may even escape with a reasonably dry week, while other get a good soaking from time to time. Cool, sometimes very cool for all, it is doubtful that anywhere will reach 21c (70f) in the coming week in spite of sunny spells. Some of the colder spots of Wales and the Marches may even see an unseasonable ground frost by the end of the week.[/font][/color]

[color=rgb(0,0,0)][font=Helvetica]The remainder of Sunday afternoon is rather cool and windy, strong to gale force gusts especially for North Wales, a scattering of showers, heavy in places, as usual some of us escape with a dry afternoon. Maxima this afternoon 16 to 19c and much as they will be all week. We should be seeing 19 to 22c at this time of year on average, so a cool week indeed. The fresh to strong NW wind continues tonight, clear spells and dry for most, but some showers rattling into NW Wales and Cardigan Bay, lightning and hail may be a feature of these. The wind prevents temperatures dropping so low, around 10c in general.[/font][/color]

[color=rgb(0,0,0)][font=Helvetica]A deep and large low pressure is circulating over Scandinavia for much of the week, dragging Arctic air south across the UK. Sunny intervals with hit and miss showers on Monday, some places catch heavy downpours with hail, temperatures in the 16 to 19c range, some decent sunny intervals but a fresh NNW wind.Clear periods, less wind and cool overnight, down below 10c for most of us. Again showers may continue to train down the Irish Sea into northern and some western parts of Wales through the night, so a rather wet night in places here.Tuesday sees plenty of cloud with more widespread showers and possibly longer spells of rain, especially for NW Wales and the NW Midlands. Very cool on Tuesday 'highs' just 13 or 14c over Snowdonia and 15 to 17c elsewhere. Clearing skies and reducing windspeeds means some low temperatures for August on Tuesday night, widely 5 to 8c, and 2c for parts of inland Wales and the Marches, so the chance of a of grass frost locally. Another sunny intervals and showers day on Wednesday, more chance of some areas escaping with a basically dry day though. Highs Wednesday back into the 16 to 19c range, best for the Midlands and coastal South Wales sheltered from the cool NNW breeze which will though be lighter. Another very chill night for Summer to follow, coldest spots over inland Wales again, down to just 3c with a grass frost just possible very locally. [/font][/color]

[color=rgb(0,0,0)][font=Helvetica]Lighter winds too on Thursday with a slacker pattern over the UK, sunny intervals and some showers again, the odd heavy one in places, again some areas stay essentially dry while the next village gets a prolonged soaking with a clap of thunder! Familiar but cool temperatures between 16 and 19c, it will feel pleasant enough in the sunny breaks given only gentle breezes on Thursday, a few spots in the Midlands perhaps touching 20c. Clear spells and some showers overnight, chilly again temperatures in the 4 to 8c range away from cities and coasts. Similar Friday too, showers in places, some pleasant sunny intervals, cool though for August, maxima generally in the 16 to 19c range yet again, perhaps very cool though for NW Wales where showers may 'gang up', and if so no better than 15c here. Clearing skies means that Friday night is yet another very cool one down to 8c generally, 4c though locally with mist and fog patches by dawn. [/font][/color]

[color=rgb(0,0,0)][font=Helvetica]Bank Holiday weekend and changes as an albeit somewhat tenuous ridge crosses the UK trying to kill off most of the showers. Saturday hopefully will be a largely dry and bright day although still on the cool side highs 17 to 20c so a slight improvement. The ridge may just about hang on for Sunday but an Atlantic low is heading towards Ireland threatening rain and wind as we go through the day, and quite likely into Wales at least by evening. Holiday Monday may see us entering another unsettled spell although a warmer one. Showers or longer spells of rain the guesstimate then for Holiday Monday with a low set to cross Britain, at least milder SW winds taking over by then![/font][/color]
