Wicklow Weather have issued and advanced weather advisory, while MET Eireann have issued a status Yellow Low Temperature Warning for tonight.
The Aughrim based weather station posted “This is an advanced weather advisory and not an alert or warning advisory.”
A heads up on a possibly severe cold outbreak.
Our advise over the coming days is to keep a very close eye on our national and local weather forecasts as we enter a more reliable forecasting time frame.
We expect temps to slowly drop off later this week and by Sunday/Monday we expect a bitterly cold easterly airflow to move in frigid cold air to NW Europe. This timeline is not set in stone just yet.
Latest model consensus moderates between a cold outbreak (some snow but nothing too severe) with some models signalling a severe cold outbreak (See Image above) with daytime temps not rising above freezing by mid next week with widespread heavy snowfalls and a windchill/feel like temperature at lower levels/populated areas of -7c to -11c.
As this is an easterly airflow the highest risk areas will include Leinster, East Munster and East Ulster and Midlands. However some models put all of Ireland at high risk of heavy snowfall and very low temperatures.
How long will this cold last: Between 3 days to 7 days?
Wicklow Weather confidence level is based on the timeline. Once we are within 3/4 days of the event we will either begin to issue “alert or warning” advisories. Our next update on model output will be posted at 2100hrs tomorrow, Wednesday.
