Afternoon update: Rain showers are developing this evening and sometimes continuing into Monday

The increase in cloud cover this afternoon was probably a clear sign that our period of fantastic weather is coming to an end. A persistent and slow moving upper level storm system will create showery conditions through Tuesday. And a steady outflow will keep cloud cover locked in and temperatures well 10 degrees below normal for mid-August. Needless to say, this isn’t the best beach or outdoor weather to start the week.

Until tonight : Scattered showers this evening will become more numerous after midnight. Some of these showers will include bouts of moderate to heavy rain. Low temperatures will be in the low to mid 60s with a light easterly wind.

Tomorrow (Monday): Light and intermittent showers will be possible throughout the day, but it won’t rain all the time and overall rainfall amounts may only average 0.1 to 0.25 inches (locally greater amounts are possible). A few rumbles of thunder are also not to be excluded in the afternoon. Fairly chilly with overcast skies, highs in the 70s and a light northeast wind at 5-10 mph. Showers and isolated thunderstorms continue tomorrow evening, with low temperatures in the mid-60s.
