Upper low swings through
The best chance for rain Tuesday will be north of Portland / Fryeburg as an upper level low spins eastward. The best chance for a pop up thunderstorm appears to be for the central part of the state this afternoon. As the upper low slides east, showers become isolated Tuesday night, then dissipate all together by Wednesday morning.
Rain estimate from 4 AM Tuesday to 8 AM Wednesday indicates the heaviest amounts for eastern Aroostook, but most of that falls early Tuesday.
Gusty winds are the main threat with any thunderstorm activity this afternoon, and the chance for severe is very low.
The recent uptick in humidity levels remains on track to fall during the day. The dew point will fall in all areas during the day to more comfortable levels Tuesday night.
With the upper low passing through, northern areas will be on the cool end of the spectrum as clouds and showers are likely to dominate the weather of the day. The coastal plain sees the most sun, hence the warmer temperatures.
Skies clear Wednesday
Wednesday starts off roughly 10° cooler than Tuesday with 40s for the north country and 50s for the coastal plain.
All in all a pleasant day with a mix of sun and clouds, low humidity, and a fall feel to the air in The County.
Next rain chance Thursday afternoon
Another cold front works through the region Thursday afternoon into the evening. Yet again, this one may fall apart as it passes through, not bringing much in the way of rainfall.
One again, northern areas are likely to see the most precipitation, with little to nothing to the south. Showers end in the wee hours of Friday as the front passes east.
For now the weekend looks dry for most areas, with just a risk of a light shower for the mountains and north on Saturday.
