PRESQUE ISLE, Maine (WAGM) - Good evening everyone and happy Monday. Post-tropical cyclone Lee brought heavy rain and gusty winds across the county Saturday. Looking at some of the rainfall reports from across the region, western areas ended up not seeing much in terms of rain shower activity. Rainfall reports from western areas vary around 1/10th of an inch of rainfall. Working further east into the valley, rainfall totals picked up between a quarter to as much as half an inch falling in spots. Central and eastern parts of the county saw the highest rainfall reports, with between an inch to as much as two and a half inches reported in some locations. While it won’t be as much rain as what Lee brought to the region, we’ll see more showers and downpours tonight as a low pressure system works into the region.

This evening’s weather setup shows the area of low pressure, actually multiple areas of low pressure slowly working north and east this evening. This is expected to stall out, at least with its eastward trek later tonight, resulting in showers and downpours lasting into the day tomorrow. Showers and downpours eventually taper off during the day tomorrow, leaving us with cloudy skies during the afternoon and evening hours. Cloud cover right now looks to last at least into Wednesday morning, with improvement expected by the afternoon and evening hours.
