The drip goes on ...

Looks like more drips and drizzle in the forecast today as we remain stuck beneath this stalled frontal boundary. After an inch-and-two-thirds of rain over the past three days, we're expected to get more clouds and drizzle today, with occasional showers this afternoon and tonight as well. We can hardly complain, after a long summer with hardly any sustained precipitation, and news of awful flooding coming in from the Midwest.

Accumulated rainfall so far this month comes to almost 2.5 inches. That's close to the average for the first three weeks of August.

The cool temperatures are something else. Yesterday's high at BWI was only 68 degrees. That's 16 degrees below the average high temperature for BWI on an Aug. 21, and the coolest high temperature since May 18, when it was just 63 degrees.

But it wasn't close to the record "low maximum" for the date. That was 63 degrees, set on Aug. 21, 1926. A 68-degree maximum today would have beaten the record, however, besting the 69-degree high reached on this date in 1990. But today's temperatures should rise above that, into the low 70s. That's still cool. The average high for an Aug. 22 in Baltimore is 84 degrees.

But we haven't seen the last of the summer-like temperatures. Not by a longshot. The sun should creep back into sight by Friday, with highs in the low 80s. And we'll be back in the 90s for the weekend, as the stalled front drifts back to our north, bringing us back into the warm, muggy southern flow. Look for high heat indexes again until another cool front washes it all away for the first week of school for many local kids. Here's the discussion from Sterling.
