High pressure will build across the Saint John Valley today and Wednesday, bringing plenty of sunshine, dry weather, and unseasonably warm temperatures. Some smoke from Canadian wildfires will remain high in the atmosphere today, creating a hazy appearance to the sky at times, but it is not expected to have a significant impact on air quality. Afternoon temperatures will climb into the mid-to-upper 80s both days, while overnight lows will cool into the upper 50s tonight and the mid-60s Wednesday night. Winds will remain light, becoming a gentle southwest breeze Wednesday afternoon. Patchy fog may develop late tonight into early Wednesday morning, especially in low-lying areas.

By Wednesday night, increasing clouds ahead of an approaching cold front from Quebec may bring a slight chance of a few showers, although many areas will remain dry through much of the night.

The cold front will move closer on Thursday as high pressure shifts off the Mid-Atlantic coast. This will lead to cooler conditions, with afternoon temperatures settling into the upper 70s. There will be a chance of showers across the Valley throughout the day, although rainfall amounts are expected to remain light. A chance of showers will continue into Thursday night under mostly cloudy skies, with overnight lows in the low to mid-60s.
The cold front will move across the Saint John Valley from Thursday into Friday, bringing the potential for showers through Friday morning. Rain will gradually taper off from west to east, with improving conditions expected by Friday afternoon as skies become partly to mostly sunny. Afternoon temperatures will reach the upper 70s, while northwest winds will develop behind the front. Friday night will be mostly clear and cooler, with lows settling into the mid-to-upper 50s as high pressure builds south from western Quebec.

High pressure will dominate the weather through the weekend, providing abundant sunshine, dry conditions, and comfortable temperatures. Highs on Saturday will reach the upper 70s, with overnight lows in the mid-50s under mostly clear skies. Sunday will remain sunny with highs around the low 80s, making for another pleasant summer day.

Clouds will begin to increase Sunday night as the next frontal system approaches from the west. A slight chance of showers will develop overnight, with lows in the upper 50s. By Monday, the approaching front will bring a chance of showers and isolated thunderstorms, especially during the afternoon. Temperatures will remain seasonably warm, with highs in the upper 70s. Shower and thunderstorm chances will continue Monday night under mostly cloudy skies, with periods of rain and a few thunderstorms likely across the Saint John Valley. Overnight lows will once again fall into the upper 50s.
