POTENTIAL RISK OF GOOD SNOWFALL NEXT MONDAY INTO TUESDAY FOR PARTS OF IRELAND
Temperatures across Europe this morning
Early next week models are showing the potential for a colder blast of polar maritime air to effect Ireland Monday night into with cold upper air temperatures at 850hPa at around -6C to -7C.
At present a area of low pressure centred or near Iceland will feed in a cold northwesterly (Polar maritime airmass) across the country next week. A band of precipitation associated with the areas of low pressure system looks set to pass over Ireland falling as rain sleet or snow for a short time, further heavy wintry showers look set to follow behind this system with snowfall possible across mainly west Munster, Connacht and Ulster with a few showers also possible across the midlands. The current outlook from the latest GFS and ECMWF model are much the same shown this risk.

Current models runs show that there will be a covering of snow on Monday Night into Tuesday morning to some lower level areas along with higher ground areas. At the moment it is to early to go into details as this areas of low pressure could yet shift further south or further northwards leading to a change in the forecast.
This is around 115hrs away and is within a good enough time frame roughly 5 days. If we keep seen this setup by Friday and Saturday then is will be interesting and in a very good time frame. This has been showing on some models for the last week nearly.
I know many will want to know more but its not possible yet a could be late Sunday before we get into any fine details.

once this system passes early next week there are sign that we will then see a east to northeast airflow leading to colder conditions by day and over night with a sharp frost and icy conditions. There will also be the risk of weather fronts moving in from the Atlantic bumping against the colder conditions turning precipitation to snowfall in some areas.
I will update on early next week again either late Friday or Saturday when the outlook will be much clearer.
