There is a lot happening this first weekend in August with the Pan-Mass Challenge being one of the bigger events. None of the riders want to ride in the rain and the good news is, depending on the route and the day you are riding, you could make it through the race rain free or at least without any prolonged rain.
Today we have a chance for showers in the afternoon from about 1PM to 7PM. Some of these showers could grow large enough to become thunderstorms, but I am not expecting any severe weather today. Severe weather would mean hail, damaging winds or tornadoes and the atmosphere isnít primed for that.
Highs this afternoon will reach the upper 70s to lower 80s, and with the added humidity itís going to feel quite summery. Of course today begins the final month of meteorological summer. During this month the biggest things you will notice are a loss of light and loss of heat. Although we havenít had many 90 degree days this summer, the chances of them occurring will decrease throughout this month. This is our last weekend of 8PM hour sunsets as we are losing over 2 minutes of daylight each day. The next time the sun sets after 8PM on a weekend is the 16th of May 2015.
You likely noticed itís a bit muggier today and this is going to continue into the evening. Overnight skies remain partly cloudy with some patchy fog. You might have to put on the air conditioning depending on your tolerance for the moisture in the air.
The frontal system which cleared us out Monday and introduced such a nice stretch of weather this week is going to back westward to the coast this weekend. An area of rain now over the southeastern section of the Atlantic Seaboard will ride north along this front. Iíll be updating the forecast on Twitter @growingwisdom. Please follow me there.
The highest risk of rain is roughly south and east of a line from Providence, Rhode Island to Plymouth, Massachusetts. Since the PMC starts west of this line tomorrow, I expect the first several hours to be dry for riders.
The wettest period of the weekend appears to be from about noon on Saturday to 8PM. Sunday will be drier overall, but the risk of showers isnít zero. Itís going to be the type of day where you should have a back-up plan if youíre outside. The map below shows how much rain might fall this weekend. I think it's a bit too far west in it's thinking, but you can see that the most rain is south and east.
Northern and western New England might escape the entire weekend rain free, but there will be an abundance of clouds and temperatures only in the 70s.
Next week looks less unsettled especially after Monday when there is still a risk of a few showers.
Tropical Storm Bertha
We do have our second named storm of the season in the Caribbean this morning. This storm is likely not going to reach hurricane strength as it moves westward and eventually curves right. This path, which you can see below, will keep the storm off our coastline next week and poses no threat to the mainland of the United States.
If the storm does remain a tropical system when it passes off our coast, there could be some big waves next week and with a warm and sunny forecast it could be a good time to head to the beach.
