Showers redeveloping this afternoon across PEI..

Wednesday, October 17th 6:30am.. A strong fall storm moved across the northern Gulf of St Lawrence yesterday which resulted in the wind and rain. This system is now east located off the east coast of Newfoundland and continues to move away. A weak ridge of high pressure is now cresting over the island as it also moves east across the Maritimes. This feature should give some sunshine to the island for a few hours this morning but skies will cloud over this afternoon as another cold front approaches from the west with showers developing towards mid/late afternoon. The frontal passage occurs this evening with a wind shift to the west. This will usher in the coldest air of the season so far resulting in showers changing to flurries snow pellets/ice pellets by dawn tomorrow which will then continue all day Thursday.  Some sunshine expected on Friday as a ridge of high pressure crests over the island. Clouds thicken up again later Friday as the next weather system approaches. This system will be much like yesterday ‘s storm passing across the northern Gulf later Friday accompanied by rain and strong winds. The associated cold front sweeps across the island near dawn on Sunday morning which will be accompanied by a wind shift to the NW resulting in falling temperatures and showers changing to flurries as the cold air returns. Clearing skies on Monday as a ridge of high pressure moves across. A warm-up accompanied by clouds and rain develop on Tuesday.
