DAYS 1-5 (NOVEMBER 7-11)
The large scale weather pattern dominating is a zonal (west to east) flow. This means that weather systems are on the move and not lingering. Overnight, a warm front pushed through, and late evening lows in the 40s were followed by a temperature rise into the 50s, along with higher humidity (dew point nearly matching but in general trailing the temps by a degree to a few degrees). Rain showers also moved through most areas, and with the help of a trough of low pressure, a swath of widespread showers will move across eastern CT, RI, and southeastern MA into mid morning before departing. Between this and an approaching cold front we get a slice of sunshine and a mild day with highs topping 60 across most of the region. The cold front trailing low pressure moving across southeastern Canada will swing through our region late this afternoon and evening, producing a few scattered rain showers, and a sharp turn to colder weather overnight. This sets up a fair but chilly Wednesday with below normal temperatures, as high pressure builds from the Great Lakes across northern New England / southeastern Canada. The next low pressure system makes a run at our region via the Great Lakes on Thursday. It’s quick-moving, as previously noted, so clouds move in rapidly ahead of it Wednesday night and a band of precipitation associated with warm air advecting in aloft arrives in the pre-dawn hours with air cold enough that some if it can fall as sleet and/or wet snow, especially north of I-90. But this system is going to be moving along a non-supporting upper air flow and won’t be strengthening, but weakening rapidly, and as the initial band of precipitation exits as quickly as it arrived, additional precipitation will start to dry up so anything that falls after the initial burst would be limited, and in the form of very light rain. A weak surface low will move eastward along a frontal boundary which will probably never lift any further north than the South Coast region, so with the exception of a possible brief shot of mild air along the South Coast, most of the area will have a light northeast flow and chilly weather Thursday. This all slides away to the southeast Thursday night and another surface wave passes well south of the region late Friday, but during the day Friday an upper level trough will swing trough with lots of clouds. These can produce a spot shower of rain and even graupel in isolated locations, otherwise expect generally dry weather Friday. High pressure builds in Saturday with dry, breezy, and chilly weather for Veterans Day.
TODAY: Cloudy start including widespread showers into mid morning from eastern CT through RI and southeastern MA, then emerging sun and passing clouds before clouds increase again northwest to southeast later, with a few scattered showers possible northwest to southeast afternoon.

DAYS 6-10 (NOVEMBER 12-16)

DAYS 11-15 (NOVEMBER 17-21)
