National Outlook

SUMMARY: Turning colder from Wednesday with rain turning to sleet in the southeast on Wednesday evening. Sunny spells and showers of rain, hail and sleet for the remainder of the week and next weekend, with temperatures a few degrees below normal and a widespread frost each night.

TUESDAY NIGHT: Outbreaks of rain continuing in many areas overnight, however a clearance from the northwest will mean much of Ulster and Connacht will be dry by morning, with patches of mist and fog developing. Frost will set in quickly after dark in the northwest, with lows of between -2 and +1 degrees in Ulster and north Connacht. Less cold elsewhere with lows of 3 to 7 degrees in a light northerly breeze.

WEDNESDAY: Rain becoming persistent again in the east and south, heavy at times. Clearer in the northwest with showers. Northerly winds will mean a cold day overall, and it will become cold enough for the rain to increasingly turn to sleet through the afternoon and evening in the midlands, south and east with snow on high ground. A cold day with afternoon highs of just 3 to 5 degrees in light northerly winds.
The rain, sleet and snow will clear away eastwards on Wednesday night, with showers in the west and north. Frost will develop in lows of -1 to +2 degrees.

THURSDAY: A cold day, with bright spells in the south, but widespread showers over the northern half of the country. Some of the showers will have a wintry mix of hail and sleet at times. Feeling cold in a brisk northwest breeze, with highs of 4 to 6 degrees.
Mostly dry Thursday night, with showers retreating to western and northern coastal areas. A sharp frost in places with lows of zero to -3 degrees.

FRIDAY: Sunny spells and scattered showers on Friday, but lighter winds will mean the showers remain largely in the northwest without getting too far inland. Again some of the showers will be wintry, especially over high ground. Highs of just 3 to 5 degrees in light westerly winds.
Another sharp frost on Friday night with lows of between -2 and +1 degrees.

NEXT WEEKEND: Next weekend will be mainly dry with a mix of sunshine and showers. Remaining cooler than average with highs of 3 to 5 degrees on Saturday and 4 to 7 degrees on Sunday, with a widespread frost on both nights.
