Cool Break, More Storms to Follow
Posted by Chris Lambert
Typically, a morning with fog, patchy drizzle and temps in the 60s would be something to complain about this time of year, and we can do that, but at least it's a refreshing break from the heat and humidity of the last several days. I wish I could say it'll all burn off and we're on easy street from here on out, but we're not.
Lots of low level clouds and an onshore breeze hold temps down this afternoon to 70 or less along the coastline, especially along the North Shore. Well inland, we'll manage to sneak into the mid to upper 70s. A few breaks in the overcast allows for some sun to get on through, but any sunshine helps destabilize the atmosphere, and triggers more showers and storms later in the day along the front stuck across the area. We'll get our dry hours in at times today, but overnight, that will be harder to do.
As energy in the atmosphere and a wave of low pressure ride in from the west this evening, showers and storms with locally heavy rain, become more numerous. With the atmosphere loaded with moisture, it doesn't take long for pockets of downpours to produce an inch or two of rain in spots. Since the threat for that is there, a flood watch is in effect from this afternoon to tomorrow afternoon. The highest threat for street/urban flooding is overnight and early tomorrow morning. Some rivers and streams may near their banks by tomorrow afternoon, so we'll watch for that as well.
It won't rain all weekend, but more storms are scattered about on Saturday and Sunday.
