Rinse, repeat, flood watch

When the sun made an appearance this morning, the light re-animating  the lush foliage reminded us of just how deeply gloomy the last few days have been.

Unfortunately, on a day like this the concept of the atmosphere as an “ocean of air” feels like more than a metaphor.

An additional 2.5 inches of rain is possible this afternoon and tonight in some areas, and thus the National Weather Service has posted a fresh flash-flood watch for the region until 2 a.m.

Since Thursday morning, totals in parts of Montgomery County have approached 2 inches, with 2.5 measured in Palm.

The next round of storms, due to get underway in a few hours, could pack more sound and fury  as a cool front interacts with the saturated air.

The weather service is saying that an inch of rain in a 45-minute period would be enough to set off flooding if it happened to land on a place already inundated.

So far, no major flooding has been reported, although the Perkiomen Creek at East Greenville crested at just over 5 feet, about a foot above flood stage.

With all the clouds and rain, once again the official temperature won’t hit 90 this afternoon. As mentioned, this marks the longest wait for a 90-degree reading since 2003.

In records dating to 1874, this year ranks in the top 30 for the latest-occurring first 90-degree reading.
