Rain tops 2 inches in spots; more due
The drizzle and spit continues across the region, and in some places it has produced some impressive overnight totals. More than 2 inches of rain had fallen by daybreak today in parts of Prince George's County and on the lower Eastern Shore, where they badly need rain for the winter grain crops. Here are some totals, taken from the online resources of the volunteer Community Collaborative Rain, Hail and Snow Network (CoCoRaHS).
Friendly, PG: 2.57 inches
Oxon Hill, PG: 2.15 inches
Salisbury, Wicomico: 2.05 inches
Pasadena, AA Co.: 1.11 inches
Ellicott City, Howard Co.: 1.00 inch
Eldersburg, Carroll Co.: 0.96 inch
Jacksonville, Baltimore Co.: 0.9 inch
Long Green, Baltimore Co.: 0.89 inch
Cockeysville, Baltimore Co.: 0.65 inch
Officially, Baltimore-Washington International Thurgood Marshall Airport has recorded 1.2 inches since the rain began, bringing the month's official total to about 1.6 inches. The average for an October in Baltimore is 3.16 inches, so we're still running very dry.

There's is still plenty of moisture available, sweeping north from the Gulf and the Atlantic. The image at the top of this post is a water vapor image from a NOAA satellite. There's more rain expected through Saturday.
And it comes none too soon. This week's Drought Monitor map, which shows agricultural drought conditions across the state as they stood on Tuesday, rated 6.5 percent of Maryland to be in "extreme" drought for the first time this summer. The worst conditions were found in western Montgomery, Prince George's and Charles counties. Two-thirds of the state was experiencing severe to extreme drought.
Streamflow data also looks better, for now, but flows are likely to subside quickly after the showers quit. This rain has surely helped to ease the situation. But the drought is not over.


Comments
Frank,
Love this blog. Has anyone done any studies on how the quieter hurricane seasons impact drought. I know that quite a few of these end up dissipating right over Georgia , Florida And Alabama and even we here in the mid Atlantic benefit from the "leftovers". Now I am not hoping for a active destructive Hurricane to hit us and maybe that is why no one talks about this angle (excepting you mentioning it a few posts ago to help us in a way). But it seems like the lack of these storms the last couple years seems to have a lot to do with lower water tables down south at least.
Just my novice thoughts.
