Blocking High

The end of January has seen a lot of very quite and cold and sometimes frosty weather. It has not been nearly as severe as what we experienced in December but the temperature has still dipped to minus 7c. The coming few weeks see a cold pattern continuing up to the first week of February before the Atlantic once more tries to make inroads but it is too early to say yet how this will pan out. Overall models signal a low overall rainfall pattern for February continuing the drier than normal Winter theme. Since November 1st there has been 280mm of rain in Sligo whereas in a normal mild 3 month period this figure would be closer to 400mm. There has also been 41 days of frost while in some Winters there was only 10 to 20 days.
