You will have noticed that it’s cold out there. The descent from Indian Summer to Arctic Winter seemed to happen overnight, and the bad news is that it’s not going to get much better in the immediate future, with temperatures tonight rising no higher than 6 to 9 degrees Celsius.
According to Met Éireann there will be frost tonight in parts of the midlands, east and south, with rain and drizzle spreading from the Northwest.
Tomorrow will be milder and generally dry after some rain in the morning, with temperatures reaching the dizzying heights of 10 to 13 degrees Celsius.
Sunday will be cloudy, with some rain in the north and west. Parts of Munster and Leinster will see a little sunshine on Sunday.
If you are driving in frozen conditions AA Roadwatch recommends that you: Don't brake fast under any circumstance; Reduce acceleration but don't take your foot off the accelerator completely; and Use the highest gears possible.
AA Roadwatch also points out that there are a number of events likely to cause traffic delays over the weekend.
The Ireland versus Iran World Cup Qualifier tomorrow means that parking will be prohibited from 8 a.m. on various roads around Lansdowne Road.
The Dublin Simon Fun Run at the Phoenix Park takes place on Sunday. Various roads in the vicinity will be closed between 1.30-4.30pm.
The Ireland versus Samoa rugby match on Sunday will lead to the same restrictions as for the previous day’s football match.
The phenomenal interest in the Harry Potter film, which previews tonight across Ireland (with the full opening next weekend), should ensure that there is heavy traffic on the approach roads to most cinemas.
The most eagerly awaited film for a generation, Harry Potter and the Philosopher's Stone is expected to become the most popular children's picture of all time.
Critics have been unanimous in their praise of the film, based on the book by J.K. Rowling. Her four books about Harry and his adventures at Hogwarts School of Wizardry are popular with children and adults alike, and have sold 100 million copies in 46 languages.
The return Swift sailing from Holyhead to Dublin at 9.15 tonight will not sail due to the weather conditions. For further details you can contact Irish Ferries at 1890 313131, Stena Line at 01 2047799 and Seacat at 1800 551743.
