OK, I was going to post a longer update on the rainfall on Wednesday but instead I posted this entry.
There was additional rainfall after my initial update posted at quarter to seven PM yesterday. And in the past two hours, additional bands of rainfall have formed now that the elongated warm front associated with the old cut-off low has pushed north of the immediate D.C. and Baltimore areas.
UPDATED 2:04AM 5/3/2014: I had intended to post this image with the original entry but forgot to do so. It is the high-resolution surface map for the mid-Atlantic and central Appalachians at 3Z May 1, 2014 (11PM EDT April 30, 2014) and shows the orientation of the warm front in question. Obviously, that is not how the map looks now. Click on image for larger version.
End of update.
A flood warning (as opposed to a flash flood warning) is in effect for the District and much of the area through 8AM. In fact, it stretches across northern Delaware, eastern Pennsylvania, and much of New Jersey as well though the duration varies.
The final daily rainfall totals for April 30th and for the storm total (so far) stretching back to Monday at the four regional civilian climate stations are as follows:
KDCA: 2.70 inches (daily record); 4.02 inches
KBWI: 3.06 inches (daily record); 4.62 inches
KIAD: 3.99 inches (daily record); 5.35 inches
KDMH: 3.99 inches; 5.67 inches. Yes, KDMH -- the Maryland Science Center at the Inner Harbor in Baltimore, Md. -- had an identical amount as Dulles Airport. Also, KDMH does yet have a full 30-year climate record.
Briefly, I would like to mention the 10 to 24+ inches that caused so much damage in Pensacola, the western Florida panhandle, and the Mobile Bay area including Mobile, Ala., itself.
Tweets stating estimated Pensacola, Fla., and Mobile, Ala., precipitation totals for April 29, 2014 and put in context of top 3 events for both locations.
This Capital Weather Gang entry has some good pictures and images including three of the four images posted (radar estimated precipitation map, second picture of washed out car, and Pensacola and Mobile preliminary precipitation amounts for April 29th sent in tweets).
NWS Doppler radar estimates of precipitation for the Florida panhandle and adjacent portions of other states including the Mobile Bay area for April 29 - 30, 2014. The legend is on the right. The magenta and violet colors are 14 to 18 inches, though even higher amounts were recorded locally.
Before concluding, I want to post this picture -- directly below -- of a washed out roadway in Pensacola, Florida.
It is a picture of Scenic Highway, a portion of which collapsed due to the flooding, taking not just the roadway but some vehicles with it.
The burgundy red car in particular sort of attracted my attention. Now I don't drive a car -- much less own one. However, that burgundy red car intrigued me. It looked like it was a nice burgundy red car. I can't tell the make or model, but then again, I'm not exactly expert at that. There is a silver-hued pickup truck next to it.
Here is another picture that came from the CWG entry linked above (whence I also got the satellite image for the above-linked blog entry). It was probably taken at a slightly different time.
I showed it to a co-worker, who joked that this car may very well end up on a CarMax lot.
OK, that's all for now.
I'll post final Baltimore/Washington regional storm totals once the rain is ended as well as the full April monthly and year-to-date totals and comparisons to normal. However, I might not be taking the computer home on Thursday evening, so it would have to wait until at least Friday night.
