Skies remain mainly cloudy tonight as a weakening cold front approaches from the west. A few scattered light showers may crop up later tonight, but nothing of any significance is expected. Patchy fog develops late as well. Low temperatures in the upper 40s to low 50s. Winds near calm.
Low pressure, centered over Lake Superior Wednesday morning, gradually moves northeastward and will be in Quebec later Thursday. It will swing the cold front through western Massachusetts and then offshore early Thursday. A chance of a shower early in the day, otherwise morning clouds should give way to increasing afternoon sunshine as the westerly flow behind the front dries out the atmosphere. Highs will nicely rebound into the upper 60s and a few low 70s. That’s about 10 degrees over normal for the middle of October. Southwest winds under 10 mph.
Things get a bit dicey later Thursday night and early Friday. Models are showing an area of low pressure forming along the cold front to our south. The low is expected to ride up the coast and be positioned close to eastern Massachusetts early on Friday, then shift east through the afternoon. With this in mind we should see clouds returning early Thursday night, with a round of showers moving across the area overnight into very early Friday. It is possible that we could have a period of moderate to heavy rain during the overnight, but the system will move through quickly and the rain will shut off by early Friday. Skies become partly cloudy by Friday afternoon. Lows Thursday night in the low to mid 50s, highs Friday in the mid to upper 60s. It will become quite breezy during Friday afternoon with a freshening west wind that brings gusts to around 25 mph.
Friday night and Saturday will remain generally partly cloudy and dry. Cooler air will begin to infiltrate the area as lows fall into the upper 30s through the outlying areas to the mid 40s in greater Springfield. Highs Saturday only in the low 60s.
Another approaching cold front will bring an increase in clouds Saturday night into parts of Sunday. Although the front is likely going to be moisture starved there is a slight chance of a shower Saturday night or early on Sunday, otherwise it looks to be another nice afternoon on Sunday. Much cooler air will filter in behind this front as highs struggle to reach 60 on Sunday, after lows dip into the 30s Saturday night.
Monday, similar temperatures to those of Sunday with a mix of clouds and sun.
Next week most likely will feature the coldest air of the season so far, but more on that this weekend.
