The midweek rain was certainly welcome.  Any amount of rain helps the deficit, but we're still far below yearly rainfall averages.

Finally enought pitter patter to amount to something!!  The rain earlier this week certainly put a dent in our rainfall deficit, but we're still far below the yearly rainfall average.  Take a look at the radar at 7PM on Wednesday, May 9th.

This is exactly what we needed -- a large, uniform, swath of moisture for a few hours.  Right here in D.C. we received a little over a half inch.  Folks on the Eastern Shore got some of the heaviest rain with rainfall totals over two inches in some spots!  The rain is certainly much needed, as many areas across the region remain under a moderate to severe drought.  Here's the most recent drought index.

Now, you might be wondering why the Eastern shore is still under a severe drought with over two inches of rain Wednesday.  The drought index is issued every Thursday morning, but the data is only recorded through Tuesday.  Since the bulk of the rain fell on Tuesday and Wednesday, this map doesn't show how the drought is affected by that rain.  We'll have a better idea next Thursday on how the impact of this weeks rain on the drought. 

Here's a list of some rainfall totals across our region from our WeatherBug locations.

WeatherBug rainfall totals from Tuesday and Wednesday

You're seeing that right with over two and a half inches of rain in Ocean City, MD.  On the other side of the Bay, rainfall totals weren't quite as impressive, comparatively, with about a quarter to a half inch on average.  As mentioned, it's wonderful to receive the rain, no how much we get when it's particulary dry.  We do still need a few more good soakings to catch up to the yearly averages. 

Yearly Rainfall & Departures

Before the rain on Tuesday, D.C. only had 3.23" (as of May 6th) of rain since March 1st.  There have only been 5 other years we've had less than 3.25" of rain from March 1st through May 6th.  That gives you an idea of how dry this spring has been, so far. 

No significant rain is in the forecast through the weekend, but late Sunday through early next week we could see the chance for a few showers.  The rain dances continue.
