After the mostly sunny and mild day we experienced Friday temperatures will cool down considerably tonight as we are reminded that it is the middle of October. Under a mostly clear sky lows fall into the upper 30s to low 40s throughout the greater Springfield area, as winds diminish to around 5 mph.
A bubble of high pressure allows for another delightful day Saturday as we sit between two unsettled weather systems. Low pressure off the North Carolina coast will move southeast of Cape Cod and be positioned just south of Nova Scotia Sunday morning. Meanwhile, system number two will move out of the Great Lakes, across southern Ontario and then to a position near Quebec City by Sunday morning. This second system will swing another cold front through here later Saturday night.
What to expect for the first half of the weekend is a mostly sunny Saturday, with some high clouds on the increase during the afternoon. Highs will climb back into the low to mid 60s with a south to southwest breeze of 10 to 20 mph. Skies become mostly cloudy Saturday night and there is a chance of a passing shower as the front moves across the Pioneer Valley overnight. Not as chilly, lows in the low to mid 40s. Winds shifting to northwest by morning at 5 to 10 mph.
Cooler air infiltrates the area during Sunday and it will feel noticeably cooler with highs only in the upper 50s to perhaps a few spotty low 60s during the afternoon. A stiff west to northwest breeze will make it feel even cooler, especially in the shade, despite a fair amount of sunshine. It becomes even cooler Sunday night as temperatures tumble into the mid to upper 30s, a few low 30s cannot be ruled out through the outlying areas, with a mostly clear sky once again.
High pressure expands over the area for Monday. A cooler weather pattern is trending for the Northeast over the coming week. Although temperatures rebound on Monday, with temperatures back into the low 60s, the trend is going to be for much cooler air by mid week and it is going to hang around for awhile. Generally partly cloudy skies prevail for Monday and through Monday night. Overnight lows dip back to the upper 30s and low 40s.
Tuesday, the cold front makes its approach and moves through here late day or in the evening. Skies change from partly cloudy to mostly cloudy by late in the day and overnight, with a chance of a few showers associated with the frontal passage, most likely late day and early at night. Highs Tuesday in the low 60s, lows in the 30s.
Then on Wednesday we begin to see the transgression to much cooler weather. Highs only in the low to mid 50s with a gusty breeze and partly sunny skies.
We will watch for the possibility of a developing storm later in the week while it continues quite cool and blustery through the late week period.
