DAYS 1-5 (OCTOBER 13-17)
A frontal boundary draped just south of the area will struggle to move northward as a warm front today and tonight as low pressure approaches from the west. The passage of this low will take it along the frontal boundary, south of much of the WHW forecast area, as the warm sector may only barely get up into the region from the South Coast to the MA South Shore early Monday before the departing low pulls the boundary south and east. Rainfall will be most widespread north of I-90 on Sunday and then more showery in nature across the region Sunday night into Monday before it dries out. Behind this comes the coolest air mass of the season so far for Tuesday and Wednesday, along with blustery conditions. This eases Thursday as high pressure builds in with more tranquil but still cool conditions.
TODAY: Cloudy. Periods of rain, most widespread near and north of I-90. Highs 55-62. Wind E up to 10 MPH.
TONIGHT: Cloudy. Areas of fog. Rain showers likely. Lows 48-55. Wind E to SE up to 10 MPH may become variable or S to SW along the South Coast.

MONDAY NIGHT: Clearing. Lows 33-40. Wind NW 10-20 MPH. Wind chill below 30 at times.
TUESDAY: Sun and passing clouds. Highs 53-60. Wind NW 10-20 MPH.
