A front will stall close to the area, and low pressure system moving along this front, will bring us periods of rain on Tuesday. This is going to be a steadier rainfall later Tuesday into Tuesday night with some places getting a half to an inch of rainfall.

Temperatures then will hold steady to slowly fall through the rest of the day. There will also be areas of fog, especially over the ridges.

Thursday will feature a mix of clouds and sunshine, with maybe a good deal of sunshine east of I-99. It will be pleasantly cool on Thursday with highs near to just above 60. Another cold front will then move through the region and usher in the chilliest air of the season so far. Friday will feature a partly to mostly cloudy sky with a couple of scattered showers, especially near and west of Route 219. Temperatures on Friday will likely not get out of the 50s. Saturday will be another cool day despite more sunshine than clouds. Highs will be in the 50s. Sunshine will give way to clouds on Sunday. Highs will in the 50s to near 60.
