Showers welcome, but Sept. still dry

The thunderstorms that swept across Baltimore and other parts of the state Thursday - part of the same line of storms that caused so much damage in New York City - brought some welcome moisture. But they did little to break the region's prolonged spate of dry weather.

Here on the WeatherDeck in Cockeysville, the storm left just 0.23 inch of rain in the bucket. The Baltimore Sun's weather station at Calvert and Centre streets shows just 0.22 inch. And out at BWI-Marshall, the National Weather Service reported just 0.06 inch. Other parts of the state - especially the extremely parched western counties - reported the most. Here are some reports from the CoCoRaHS Network:

Cumberland: 0.80 inchDrought Monitor

Williamsport:  0.76 inch

Thurmont:  0.43

Frederick:  0.41

Even so, the total so far this month at BWI-Marshall comes to just 0.89 inch. That's 1.29 inches short of the average through the 16th of the month. And there is no rain anywhere in the 7-day forecast from Sterling.

The Drought Monitor map released Thursday does not include any rain that's fallen since Tuesday. It continues to show a third of Maryland in "moderate" to "extreme" drought. The portion of the state considered "abnormally dry" increased last week from 59 percent to 84 percent.

The dry conditions are - or were, before Thursday's showers -  closing in on the "normal moisture" bubble that has surrounded Baltimore and its suburbs since some mid-August rains, leaving not quite 16 percent of the state in that "normal" category.
