Forecast discussion: A weak trough off the New England coast provided Providence with overcast skies today. Also, a warm front well to our northwest helped keep mild temperatures over the area. We will keep warmer temperatures until the end of the workweek, until colder air from Canada comes down from the north.
During the overnight, the weak trough will continue to provide us with overcast skies, and an increase in the dewpoint will create patchy fog after midnight. A weak cold front passing through Ohio will help create some showers and light rain Thursday night, and continue into the overnight hours. All precipitation will end by Friday morning, with some drier air moving over Southern New England. Once skies clear Friday night, low temperatures will fall into the upper 40’s.
By Saturday, we will continue to keep moisture in the upper levels of the atmosphere, so we will see limited sunshine throughout the day. Also, we will fall autumn like temperatures, as highs only reach the lower 60’s. This is due to colder air coming down from Canada, as an upper level trough digs into the central U.S.
As we go into Saturday night, a weak disturbance will form off the coast of New Jersey, and may provide us with some showers early Sunday morning. However, the surface low will move off to the northeast just as quickly, as precipitation ends by sunrise. A strong high pressure system to our south will bring drier air over us, giving us mostly sunny skies by Monday. But, temperatures will struggle to reach the lower 60’s.
A quick moving low pressure system will move over the Great Lakes on Tuesday morning, giving us the chance at more showers ahead of the system. The low will keeps showers in the area until Wednesday morning, with mostly sunny skies by the afternoon. Also, there is a slight chance of seeing the first frost of the year, as temperatures could fall into the middle 30’s north and west of the capital city.
