We had a fair amount of sunshine today but the clouds did fill in during the afternoon. Skies become overcast tonight as a cold front approaches and then shifts across the region overnight. A few showers may accompany the frontal passage before skies rapidly clear early on Sunday morning. Low temperatures tonight in the 40s with a light southwest wind under 10 mph.
Sunday, expect a different feel to the day than what we experienced Saturday as temperatures will be several degrees lower than today and with a feisty wind from the west and northwest it will feel noticeably cooler. Highs reaching around 60 degrees with a mostly sunny morning and a partly cloudy afternoon, but it will feel cooler than the actual temperature, especially in the shade.
Cooler air continues to filter in Sunday night. A ridge of high pressure expands over the area to be centered over the mid-Atlantic on Monday. Temperatures will quickly drop off after sunset as winds diminish considerably to near calm overnight with a mostly clear sky. Lows bottom out in the mid 30s, with a few locations possibly falling into the low 30s. Thus, areas of patchy frost should be expected into Monday morning.
High pressure is firmly in place Monday and with a southwest flow temperatures rebound into the low 60s, possibly a few of you not getting out of the upper 50s north of greater Springfield, under a mainly sunny sky. It will not be so chilly at night, lows rolling back to the low and mid 40s with just a few clouds around.
Tuesday and Tuesday night, another in a series of cold fronts will pass through the Pioneer Valley. This is the front that will deliver the coldest air of the season. Mostly it will be a partly cloudy day, becoming mostly cloudy late and overnight with a chance of a passing shower. Highs in the low 60s, lows in the mid 30s in some outlying communities to low 40s in Springfield.
A coastal storm is likely to develop south of us along the front. With much colder air overspreading the area and the low moving northeastward we could be in for a cold rain by Wednesday night. Overall, Wednesday is shaping up to be a mostly cloudy and chilly day. Highs only in the low 50s, falling to the upper 30s to 40 degrees at night. If the storm tracks far enough east the precipitation shield will not reach western Massachusetts, but this far out we are not certain of the track and how much the system intensifies so do stay tuned.
Behind the departing storm on Thursday we can expect a blustery day with gusty winds and temperatures struggling to get out of the upper 40s, with a chance of a freeze in some locations overnight.
