If you got measureable rain from those thunderstorms last night, count yourself lucky. Instruments at BWI caught only a trace, so the dry streak that began Sept. 16 at the city's station of record continues today into its 25th consecutive day. The record for Baltimore is 32 days, ending Oct. 31, 1963.

Jim Decarufel, out at the NWS Sterling forecast office said there's a low-pressure system spinning our way tomorrow out of the Great lakes. "That might have a few sprinkles here and there," he said, "but other than that, continued dry ... The worst thing is, there aren't even any tropical storms out there, and we're gonna need a couple of them to do anything beneficial."

I figured the airport would pick up a little bit of rain from last night's storms. We had 0.33 inch out on the WeatherDeck in Cockeysville. Jim said a private observer in Damascus, in Howard County, recorded just over a half-inch. But amounts elsewhere were paltry: 0.08 inch in Emmittsburg; 0.02 inch in Riveira Beach; a trace in Oxon Hill. We had 0.07 inch here at Calvert & Centre.

At BWI, it has taken us since Aug. 22 - that's 49 days - to accumulate just one inch of rain. 

"It's not good," Jim said.

Here are some other readings from around the region on last night's storm. And these.

We're now closing in on a 10-inch rainfall deficit for the year. Many streams are near record lows. Groundwater levels are falling. Here's some realtime data from a monitoring well in Granite, Baltimore County.

There's only a "slight" chance for some showers in the next few days as we work through another frontal passage and welcome some cooler air. After Friday, the forecast is clear and sunny well into next week. On Thursday of next week, if there's no measureable rain at BWI by then, we'll break the all-time rainless record.

BTW, Tuesday's record high of 94 degrees at Dulles International Airport broke not only the high-temperature record for an Oct. 9, but also the all-time record for any date in October.
