Flash flooding far west, hot & humid east

This afternoon we find a lot of different weather across the region. Big storms are firing up in far Western Massachusetts prompting a flash flood warning in western Franklin county (small red area on map). Heat and humidity are combing to the southwest of Boston, prompting a heat advisory. (orange area)


The immediate coast is enjoying a sea breeze which is keeping temperatures in the upper 70s. While there could be a thunderstorm this evening, most of the region will remain dry and warm overnight. Sunday will be another very warm and humid day with more storms over night.

Weekend specifics
Most of the shower activity this evening will be north and west of Route 495. In New Hampshire, some areas west of Concord are seeing inches of rain in stationary storms. Sunday night, I expect to be tracking a line of storms moving south and east from northern New England.
Today was the hottest of the two weekend days with many places getting into the lower 90s. The Cape and Boston had “coolest” temperatures remaining in the upper 70s and 80s with sea breezes. Humidity is oppressive everywhere. Tomorrow, high tide is mid to late afternoon for those of you heading to the beach. I recommend, as you already know, getting there very early if you want to get parking. One other option of course is to go to the beach around 4PM when people are leaving, the sun isn’t as strong and you can usually find a spot. I prefer the early morning or late afternoon at the beach as the 10AM-2PM sunshine is just too intense
Sunday, sunshine will start the day after any early morning fog burns away. The fog can be quite thick in spots between about 4AM and 7AM. The reason for the fog is that the air cools overnight to the point it can’t hold the water vapor. The air, basically turns into a saturated cloud of moisture at the ground we call fog.


In fog the temperature and the dew point are usually the same. Once the sun gets higher and the temperature rises above the dew point, the fog vanishes rapidly as the difference between the temperature and the dew point increases.
Sunday night and Monday
A cold front will drop south from northern New England overnight Sunday and the first part of Monday. Showers and some thunderstorms will form and accompany the front. The timing of the front is such that it will move through during the cooler part of the day not the warmest. Therefore, the chances for severe weather are low. However, with all the humidity, there can still be some heavy downpours. Temperatures will be warm and humidity high through the night Sunday. On Monday, drier air will slowly filter into the region. After any morning showers clearing will move through and it will turn partly sunny. It will be another warm day, but I expect a super evening of weather Monday as by then the humidity will have fallen and temperatures will turn comfortable.


From mid-August through until October (November for some plants) is perfect for planting. This is the time of year you can see where you have some gaps in the garden that need filling. Also start thinking about bulbs that might need to be ordered now.
Below is a video on a great plant I put in the garden last year at this time. The plants are looking terrific this year and had a great spring bloom.
