Forecasts for Ireland
TRENDS for the week of 15 to 21 September, 2019
— Temperatures will average 2 to 3 deg above normal, with daytime readings contributing more than relatively normal overnight lows.
— Rainfall will average 25 per cent of normal values, a little today and possibly a bit more around Sunday of next weekend.
— Sunshine will average near normal to 25 per cent above normal.
TODAY will be rather misty and overcast in many areas with outbreaks of light rain or drizzle, amounts slight except possibly 3 to 5 mm in parts of Ulster, north Leinster and northeast Connacht. Those areas will remain rather cool with highs 14 to 17 C. Further south, it should reach 18 to 20 C with a few brighter intervals especially near the south coast.
TONIGHT will remain overcast with fog and mist, and the drizzle should end after midnight, with lows 10 to 13 C.
MONDAY will see a gradual clearing trend with the morning fog or mist slowly giving way to intervals of hazy sunshine, highs 18 to 21 C.
TUESDAY to FRIDAY will be a dry and warm interval, at least in terms of daytime highs which should reach the low 20s in many central, inland southern and western counties, and 17 to 20 C in places exposed to southeast breezes from the Irish Sea or south coast. Nights will be clear except for extensive ground fog or mist forming after sunset but becoming more widespread in the early morning hours, then slowly dissipating after sunrise each day. Winds will be light and variable in this spell.
The outlook for the weekend of 21-22 September and beyond is rather uncertain as this warm spell slowly breaks down under increasing attack from the Atlantic and even the possibility of remnant tropical activity being involved. This will likely be the storm forming after the current disturbance, Humberto, which will be quite close to Bermuda by Thursday then probably moving north towards Iceland while Ireland remains under the protection of blocking high pressure. By later in the week of 23rd to 27th there could be some rather gusty winds and rain from stronger Atlantic frontal systems.
My local weather on Saturday was overcast with occasional light rain, and moderate southeast winds, with highs near 17 C.
