Sunday October 19th 5:30pm... A north-south oriented cold front just crossed PEI and is now located between the Island and Cape Breton. Showers with the front have basically moved off to the east but an upper level low pressure system will be tracking across NB tonight into tomorrow giving periods of rain to the area. A ridge of high pressure will eventually build in across the region for tomorrow night into Tuesday giving mainly clear skies.. Things then start to get interesting with the development of a closed low pressure system off the mid Atlantic coast. This system will be very slow to move into Atlantic Canada and will result in a prolonged period of unsettled wet weather which should extend into at least Saturday. The computer models continue to be at odds with each other as to where the axis of heaviest rainfall will occur. The current thinking is the heaviest rain will be confined to southern Maine.
Precipitation.. Showers or periods of rain tonight into early tomorrow giving 5-10 mms. A potential rain event will be developing south of the Maritimes but details on timing and amounts are still unclear.
Temperatures.. Say good by to the warm weather at least for a few days.. Temperatures will drop tonight and should remain below normal tomorrow with a blustery cold westerly wind. Temperatures return to normal for Tuesday and could go above normal towards the end of the work week but will all depend on the movement of the coastal low pressure system.
Wind.. Light north winds tonight incresing and shifting to brisk westerly tomorrow diminishing to light westerly for Tuesday then calm Tuesday night. Winds will shift to easterly on Wednesday as the coastal system organizes off the mid Atlantic coast.
Watches/warnings… Nil at this time
Potato harvest… 5-10 mms possible tonight into early tomorrow. Dry for later Monday into Tuesday then a big question mark for Wednesday through Saturday.. Looks wet but details are unclear at this time..
