We had a good weekend across the region, with sunshine and milder temperatures in the second half of the weekend. That all changed late Friday night, as cloud cover and showers moved into the state. Showers and downpours continued throughout the morning, with activity tapering down to light showers this afternoon and evening.
Steadier showers are once again probable late tonight, with temperatures dropping and showers transitioning to snow before, if not immediately after, sunrise tomorrow. Snow showers are predicted to fade quickly, with skies clearing in the afternoon and evening tomorrow. High pressure is likely to rise overhead over the middle of the workweek, resulting in more sunshine and colder temperatures on Wednesday and Thursday.
Going hour by hour through the rest of the evening, showers stay more isolated between now and midnight. Another wave of steady showers is forecast to arrive early Tuesday morning, accompanied by a cold front.
The cooler air, combined with the probability of precipitation, implies that rain will most likely try to change to snow, especially if northwesterly winds kick up. Overnight low temperatures will dip back into the lower to mid-30s in most areas. Northwesterly breezes tomorrow will keep temperatures from rising during the day, thus highs will most likely be set sometime after midnight.
Showers will taper off as colder air enters the region, but they will most likely take the shape of snow showers in the morning hours on Tuesday. A few flurries are still likely by lunchtime, but the majority of the action will be over.
From there, the skies will clear, revealing warmer but cooler weather for the middle of the work week. As previously said, northwesterly winds will increase during the day tomorrow, with gusts of up to 35 mph probable. The strongest winds appear to be in central Aroostook, with the northern and southern areas of the county missing out on the stronger action.
After tomorrow, the outlook calls for additional sunshine on Wednesday and Thursday. The conclusion of the work week now becomes more interesting, as an area of low pressure moves back into the state from the east.
This unusual passage of low pressure will most likely cause the storm to stay overhead or just off the coast of the Gulf of Maine. In any case, the end of the work week appears uncertain with the most consistent rain activity, with lighter shower possibilities remaining into the weekend and next week.
