Saturday, October 27th 8:20am.. A ridge of high pressure oriented East-West is currently cresting over the island and will drift off to the east later today. Clear skies and calm winds are accompanying this feature. Clouds will invade the island later this morning as the next system approaches. This system is an area of low pressure currently organizing off the US mid Atlantic coast vicinity Cape Hatteras. This low will intensify and track NE along the coast to about NYC just after midnight tonight then turn northward and begin to weaken as it tracks inland into eastern Quebec by early tomorrow evening. A secondary are of low pressure then develops near NYC Monday morning and tracks NE across the Maritimes MOnday night into Tuesday morning then moves into the Gulf by later Tuesday morning. A significant rainfall threat exist as a result of these 2 systems. It will also be quite windy especially with the first system tomorrow. Skies will begin to clear Tuesday afternoon as high pressure briefly approaches and is expected to crest across the island Tuesday night. Cloud will once again spread across the island Wednesday morning as a cold front approached front the west. The front will lie south of the Maritimes early Thursday morning then begin to lift northward again as a warm front later Thursday bring more rain. The front will then stall across the region and allow several low pressure systems to ripple NE along this stalled frontal boundary across the Maritimes for Friday Saturday and Sunday. So a wet stormy but rather mild week of weather ahead for the island.
