Forecast Issued – July 29th 2017
Brought to you by www.laoisweather.com
Overview: Breezy and showery with sunny intervals and average temperatures.
Saturday 29th July: After a fine sunny start, cloud will gradually build and showers will develop in the early afternoon. With moderate southwest breezes the showers will pass over quickly enough so rainfall amounts should be low overall. Temperatures will max out at around 19c, perhaps 20c in any sunshine. OVERNIGHT: Clear and cool in light breezes. Lows around 10c.
Sunday 30th July: Partly cloudy at first, however a band of heavy showers will extend from the northwest during the late morning. As with the nature of showers, some areas will get some heavy ones while others don’t – it is impossible to pin down exactly where the heaviest of these occur. However, moderate westerly winds will ensure that showers move through rather quickly. Some sunshine will occur between the showers making it feel pleasant as highs once again reach around 19c. OVERNIGHT: Showers dying out in the evening and skies clearing. Cool in light breezes and lows around 10c.
Monday 31st July: More or less a carbon copy of days previous as a low pressure anchored off W Scotland continues to steer in an unstable Atlantic airmass. So, sunshine to begin, clouds buildup and showers develop before dying out in the evening – however Monday’s showers should be lighter and more scattered. Highs again in around 19c or 20c at best in moderate westerly breezes. OVERNIGHT: Cool and clear conditions returning with lows of 9c or 10c.
Tuesday, 1st August: Finally, an expected break from the showery regime as the low pressure looks set to retreat from it’s five day visit to the west of Scotland. This should result in a day with good sunny spells and light breezes. Highs perhaps reaching into the low 20s – say 21c or 22c. In the evening, cloud will gradually increase from the west.
Outlook: Tuesday evening/night and Wednesday morning looks set to becoming wet and windy as an unusually deep summertime low pressure moves up from the southwest. The direction of this low pressure is uncertain once it reaches the vicinity of Ireland, so keep in touch with forecasts early next week as the situation becomes clearer: Presently though, some computer models are predicting a return to the showery regime that ended the last week of July, whilst others are suggesting high pressure builds in quickly to give a fine warm August Bank Holiday weekend.
