1. Low pressure will continue to bring a period of rain tonight.
2. High pressure over southern Canada slides east Monday through Wednesday providing fair weather and seasonably cool temperatures.
3. There is a signal for a slow moving coastal system near the East Coast late in the week. Impacts will be track dependent, which remains uncertain at this time range, while the potential exists for rain, gusty NE winds, and high surf sometime over next weekend.
