FORECASTS

TODAY will become windy and will turn colder after a mild morning to mid-day period with temperatures steady 10-12 C then falling rapidly by afternoon. A few showers and risk of a thunderstorm around the time of the cold front passage most likely inland southwest to midlands. Winds southwest 40-70 km/hr becoming northwest 50-80 km/hr and temperatures falling to 2-4 C.

TONIGHT windy and very cold with wintry showers, snow on hills in Ulster and Connacht, west Munster. Winds continuing northwest 50-80 km/hr, some higher gusts in areas exposed to Atlantic. Clear intervals near east and south coasts. A more organized area of sleety showers or light snow could track across Kerry and west Cork during the period midnight to 0400h. Lows near -2 C and feeling closer to -7 C by morning.

TUESDAY windy and very cold with wintry showers, some snow on hills. Sunny intervals between bands of wintry showers. Winds northwest to north 50-80 km/hr at times during the morning adding a chill to temperatures in the range of -2 (morning lows) to +4 C (mid-day) but less windy by mid-day and afternoon, staying rather cold with highs 4-6 C. Clearing by afternoon in most places and becoming very cold again overnight at least in areas away from the west coast.

WEDNESDAY will start out clear and frosty in the east and north with early morning lows -5 to -2 C. Overcast skies will quickly follow, as the southwest becomes cloudy from about midnight, and temperatures will rise gradually, with a brief interval of sleet or wet snow changing to rain by morning in west Munster, mid-day Connacht and east Munster, and afternoon to evening further east and north. After a nearly calm start winds will increase again from the southeast to south, reaching 50-80 km/hr by mid-day west to the afternoon and overnight hours further east. Highs by late in the day 7-10 C. About 10 to 15 mm rain expected.

THURSDAY will be party cloudy to overcast, and mild after heavy bursts of rain move through early in the day; a few showers are likely after that, with temperatures steady near 10 to 12 C. Winds moderate south-southwest 40-70 km/hr.

FRIDAY (17th) will be mostly cloudy with a few breaks, and outbreaks of light rain in places. It may be rather misty or even foggy in some northern counties especially. Lows 4-7 C and highs 9-12 C.

SATURDAY looks rather variable and bit cooler with a few brief showery intervals. Lows 2-5 C and highs 7-9 C.

SUNDAY will have morning frosts and daytime sunshine with a few cloudy intervals, lows near -1 C and highs 6-8 C.

By MONDAY 20th rain will be pushing back in. The colder high pressure area now looks to be setting up a bit further east than previous guidance but I am half expecting it to be back to the west again at least once this coming week in forecast charts, so let’s just say the week of 20th-24th seems likely to be some kind of back and forth between milder Atlantic air masses and cool dry modified arctic air, details to be determined.
