TONIGHT
Dry and cold tonight with mostly clear skies at first, but with some mist and fog forming, likely becoming widespread and dense across parts of Ulster, Connacht and north Leinster. Lowest temperatures generally of -1 and 4 degrees, with some frost, though less cold in some eastern and southern coastal parts. Winds will just be light variable or east to northeast.
TOMORROW - Tuesday 3rd November
A cold start to tomorrow, Tuesday with any frost clearing early on, but the mist and fog will gradually clear through the morning and will possibly linger in some areas into the afternoon. Otherwise it'll be a mostly dry day, with good spells of sunshine developing. However, cloud will build from the east at times, bringing a few showers, especially further to the east. Highest temperatures generally of 9 to 12 degrees in mostly light variable breezes, later becoming light to moderate northeast to east.
National Outlook
Overview: High pressure will continue to be in control of our weather for the rest of the week and indeed probably the weekend too, so it'll be settled and largely dry, with just some well scattered showers. The best of the sunshine is likely early in the period, while it'll be bit cloudier through the second half of the week. There'll be a bit more of an easterly breeze too through the second half of the week, helping to limit fog and frost. Into the weekend the winds may ease light again, so probably a bit colder, with more in the way of fog and frost possible once again.
Tuesday Night: Apart from a few isolated light showers, mainly across the east and south, it'll be a dry night with a mix of cloud and clear spells. Some mist and fog will form once again, mainly across parts of the north and west, where skies will be clearest and winds lightest. Cold with lowest temperatures of 0 to 5 degrees generally, with some frost in mostly light east to northeasterly or variable breezes. There'll be a little bit more of a moderate east to northeast breeze though in eastern and some southern parts, which means it won't be as cold here and will remain frost and fog free.
Wednesday: Any frost will quickly clear and any mist and fog which will mainly be across parts of the north and west will gradually clear through the morning and early afternoon, to leave a mainly dry, bright day with plenty of sunshine. It'll be a little cloudier at times with a few light showers, especially in the south and parts of the east. There'll be a bit more of a breeze compared to the previous couple of days, with easterly winds increasing mostly moderate, fresher though in the south and parts of the east. Cool with highest temperatures of 9 to 12 degrees.
Wednesday Night: Apart from the odd isolated light shower in the east and south, it'll be a dry night with clear spells. There'll be less mist and fog around as compared to the previous couple of nights, with just isolated mist and fog patches expected further west, as there'll be a bit more of an easterly breeze. Lowest temperatures of around 2 to 6 degrees generally, with possibly some frost further west. It'll be less cold in eastern counties and in southern coastal parts. Winds will be light to moderate easterly, a little fresher at times in eastern and southern coastal parts.
Thursday: While there'll still be bright or sunny spells on Thursday, the best of these further west, there'll be more in the way of cloud around compared to the earlier days of the week. While predominantly dry conditions will persist, some well scattered showers will feed in from the east at times. Highest temperatures of 9 to 12 degrees and feeling a bit colder than that in mostly moderate easterly winds, fresh and occasionally gusty in eastern coastal parts.
Friday: Friday will once again bring plenty of dry weather, with just some well scattered showers expected. While there's likely to be a good deal of cloud, there'll be some bright or sunny spells, the best of these further west. Highest temperatures once again of 9 to 12 degrees in light to moderate easterly winds.
The weekend: It's likely to continue mainly dry and settled next weekend, with variable amounts of cloud, some spells of sunshine and with generally just some well scattered showers likely. Continuing cool and indeed colder by night as winds will likely decrease light again, with some frost and with mist and fog forming by night, probably a little slow to clear by day.
