High pressure over Quebec and low pressure off the mid-Atlantic coast this evening are the two main weather features as we head into the long holiday weekend. The high to our north will continue to drift over New England Saturday as the low to our south drifts southward.
The precipitation shield from the mid-Atlantic low never reached the greater Springfield area Friday and with the high pushing drier air southward we were able to capture a fairly decent day on Friday. This trend will continue into Saturday as we expect the clouds and rain to remain south of the area not only for Saturday but for Sunday and Columbus Day as well.
One concern is that a weak back door cold front will slide down from the north country and with it will come periods of cloudiness and a cool day Saturday. Overall, skies should average out partly cloudy through Saturday night, but there will be periods when there are more clouds than sun during the afternoon, possibly remaining mostly cloudy for a time into the evening hours. Early morning and late night areas of patchy fog and a spot of drizzle at night are also a possibility. High temperatures in the low to mid 60s. Overnight lows in the 40s. A persistent northeast wind at 10 mph or less.
Sunday, another chunk of drier air infiltrates the region as the high sinks further south and with that we should see a mostly sunny day. Areas of patchy fog in the morning will burn off around mid morning. Highs stay on the cool side, climbing to the low 60s at best through the area. Winds continue northeast around 10 mph.
Sunday night, skies become mostly clear and as a result lows fall into the upper 30s to low 40s. Winds near calm.
Columbus Day, partly sunny. Highs in the mid to upper 60s.
Monday night through Wednesday, high pressure remains in control. Generally partly cloudy skies and seasonably cool. Highs in the 60s and lows in the 40s.
If the low pressure system had been allowed to drift northward the weather picture would have featured low clouds, cooler temperatures and periods of rain through a good portion of the weekend. Fortunately that is not the case so get out and enjoy the weekend which will be nice for checking out the foliage among other things.
