Another cool night is on the way with mostly clear skies allowing temperatures to fall into the upper 50s and low 60s through the Pioneer Valley. Some valley fog will develop through Saturday morning. We are looking dry for the most part on Saturday, however as a more southeasterly flow develops, expect more clouds and a slight risk for an isolated shower through the afternoon. Very little rain is expected though and most should stay dry.
Temperatures remain warm this weekend with highs in the mid to upper 80s Saturday, then mid 80s Sunday. We also become more humid ahead of an approaching cold front. This front will be a game-changer as we move into early next week.
Clouds will increase Sunday along with rain chances through the afternoon. Showers and a few thunderstorms are likely Sunday night into the pre-dawn hours Monday. We could see rain amounts around a quarter to half an inch overnight. We will clear out quickly Monday and our warm, humid air mass will be replaced by a much cooler, drier one.
A taste of fall on the way through mid-week with very low dew points (dry air) and temperatures only reaching 70s during the day and dipping into the upper 40s at night. We get warmer and more unsettled by Friday.
