Chilly Winds Bring In The Chill
A nice mild start to the morning with lows holding in the 40's and lwr 50's overnight thanks to clouds and a SW wind. Mild temps with sunshine are allowing temps to rise into the mid-upper 50's south of Boston with a west wind.
A cold front is pushing off the coast today with our surface wind direction shifting to the cooler NW wind direction with cold air draining in from Canada for the rest of the day into this evening. Cool air already in place in the north where it has been snowing in the northern Mountains from Jay peak to Sugarloaf. Temps this morning are in the 30's and 40's and will struggle to warm now that cold air advection is underway. This cold air will push south this afternoon.
An area of low pressure has pushed off the coast and is heading to Nova Scotia. High Pressure building in from the Great Lakes along with the departing Low will create a funneling effect of air into New England which will help to bring a cooler than normal airmass to us just in time for the trick or treaters. Winds could gust over 30 mph for a time this afternoon into the early evening.
Trick or treaters should dress warm tonight as temps will be dropping into the 40's. Near 40 degrees by 8 PM. The active winds will provide a real bite to the air. The clearing trend will continue this evening with winds diminishing overnight. Freeze warnings up along the coast as tonight will be the best chance for frost even near the beaches. Lows will be falling into the Upper 20's and Lwr 30's by dawn tomorrow.
High Pressure builds in through the midweek with sunshine and temps running about 5-10 degrees below normal. While we bask in the sunshine and throw an extra log on the fire to warm the house we will have to watch the Carribean closely.
Hurricane Tomas has strengthened into a Cat 2 Hurricane with 100 mph sustained winds, slowly moving NW at 8 mph. This storm is expected to slowly strengthen in the coming days...maybe reach a weak Cat 3 by the time it is south of Jamaica or Haiti by Thursday.
A deep trough will be swing into the Gulf of Mexico. This will be pushed further south because of an active northern stream which will likely merge with the southern stream and likely help to direct some of the moisture and heat up the east coast by the end of the week. The rainfall will likely arrive here for Thursday and Friday...This will likely come with a few inches of rainfall....but be fairly quick moving. It all should be gone by next weekend.
