Columbus Day morning greets us with chilly temperatures as the mercury generally fell into the upper 30s to low 40s overnight throughout the local area. Areas of patchy valley fog are burning off and overall we are in for a delightful day with plentiful sunshine and cool afternoon highs in the low to mid 60s. Light and variable winds throughout the day, may turn onshore along the coast.
High pressure continues to control our weather and is centered overhead this morning. A weak cold front through western New York State is triggering a few showers from the central portion of the state into the Adirondacks and upstate Vermont this morning. These showers will erode as they move toward our region but cloudiness will increase as we move into tonight. Overnight lows will not be as chilly Monday night, generally falling to the mid 40s to 50 degrees, coolest inland. Winds near calm.
Tuesday and Tuesday night, the cold front to our west tries to push across the area. It will produce nothing more than partly cloudy skies and other than that will have no impact on the area. High pressure nudges offshore as we have another day of seasonably cool temperatures. Highs in the mid 60s and overnight lows from the mid 40s to 50 degrees, cooler readings inland. Winds remain light.
A weak trough may extend northward from a coastal low off the North Carolina coast. This would prompt an increase in clouds during Wednesday with a slight chance of a shower. Highs again in the mid 60s.
A cold front approaches from the west and is expected to swing through here very late Wednesday night or early on Thursday. With that feature we maintain a threat of a few showers overnight Wednesday and on Thursday. Skies will become mostly cloudy at night, then partly cloudy later Thursday. Lows Wednesday night in the low 50s, highs on Thursday in the mid to upper 60s.
Another weak trough may develop offshore and bring a threat for more clouds Thursday night and chance of a shower Friday. Otherwise, if this does not develop we should expect partly cloudy skies with lows Thursday night in the upper 40s to low 50s, highs Friday tapering back to the low 60s.
We have been dry the past couple of months and so far through the first half of October. Through the first 13 days of October Boston has recorded just under a half inch of rain, 0.45 inches to be exact, and in the month of September we were about 1.25 inches below normal. October averages 3.94 inches so we have quite a ways to go to reach that number over the next two weeks or so. Whatever rainfall we do get this week, if any, is not likely to add much to the overall monthly total as it stands now.
