Weather: Seasonal ForeshadowingBy Greg Lawson
STAFF METEOROLOGIST -- Persistent northerly flow due to a weak quasi-stationary low right over southeastern Massachusetts brought cold Canadian air southward yesterday, helping the temperatures drop much more quickly than expected. At 6 p.m. temps were 10 degrees cooler than had been forecasted for that time the day before. The low and its associated front and rain will have passed out to sea by the time this forecast is available, leaving us in a dry, chilly air mass. Expect the skies this afternoon to remain partly to mostly cloudy, finally clearing as the weather gives way to a building high over the Ohio Valley.
Temperatures will be kept well below normal values for this time of year. It should slowly warm up as the high settles in with tonight being a bit warmer than last night and tomorrow coming within five degrees of normal Normal high is 67°F (20°C) and low is 50°F (10°C). However, another surge of cold northern air should arrive sometime Wednesday night or Thursday morning and cool things off yet again; this time we should stay dry though. The outlook is a return to normalcy by the weekend.
Today: Mostly to partly cloudy skies clearing mid to late afternoon.
Cool with a high of only 50°F (10°C).
Tonight: Cool and clear. Low of 44°F (7°C).
Tomorrow: Clear with clouds forming in early evening. Warmer with a
high of 62°F (17°C) and a nighttime low in the upper 30s (3 to 5°C).
Thursday: Cloudy then clearing. Highs in the mid 50s (12 to 14°C).
Nighttime lows again in the upper 30s (3 to 5°C).
Friday Outlook: Still unseasonably cool, but warming. Look for a
pleasant holiday weekend.
