Showers redeveloping today across PEI..

Wednesday, May 2nd 6:15am..  A warm front oriented in an east-west fashion will be located north of the Maritimes today. The region will be bathed in the warm air found to the south of this front but unfortunately some cloud and isolated showers will accompany this feature. This front will begin to sag south tonight as an area of low pressure ripples eastward. This will result in a more organized area of ran and isolated thundershowers to spread across the region. The front drops south of the region tomorrow taking the warm air with it making for a very chilly day across the island.  The front begins to lift north again as another area of low pressure located in the Great Lakes moves NE. This feature is expected to track along the St Lawrence River Valley during the day to be located near Gaspe Bay Saturday morning. Temps will begin to warm-up as the front moves north but will be accompanied by another round of rain as the low pressure system approaches. The associated cold front will then sweep eastward across the island before noon on Saturday bringing an end to the rain. Sunshine will break out as high pressure approaches for the remainder of the weekend and into early next week.

Precipitation.. Few showers today becoming more frequent towards evening as the front drops south. Showers will become periods of rain at times heavy tonight as the area of low pressure approaches. The rain should taper back to a few showers by noon tomorrow giving amounts near 10 mms. Up west could see slightly more. There is a risk of thundershowers which could give isolated higher amounts as well. Chance of showers exists for the remainder of tomorrow into Friday. These showers once again become more frequent during the day on Friday becoming periods of rain Friday night as that second area of low pressure approaches. The rain should taper back to showers Saturday morning then ending by noon. Rainfall amounts will again be in the 10 mm range. Some dry weather begins Saturday afternoon and extends into early next week.

Temperatures.. A warm day ahead for the island with temps expected in the high teens but better enjoy it as temps will be much below normal tomorrow. Almost back to normal for Friday but still a little cool. Saturday should see another fairly mild day then cooler more seasonal air invades for the remainder of the week. So tee-short weather today, sweater/coat required tomorrow.

Wind..Brisk SW winds today shifting to N-NE after midnight tonight which will continue through tomorrow. Winds become E-SE on Friday shifting to brisk southerly on Saturday then W-NW after the cold frontal passage during the afternoon. Light northerlies for Sunday and Monday.
