More rain, more clouds, forever ...

Or at least that's how it seems. The forecast out of the NWS Sterling forecast office looks exactly like it did at this time last week: Rain chances, showers and thunderstorms as far as the eye can see.
Today marks the fourth straight day of measurable rain at BWI-Marshall Airport, with about an inch and a half in the gauge since Friday, including what's fallen so far this morning. Here are some more 24-hour rain totals from across the region this morning. The Eastern Shore seems to be getting a good soaking.
Easton: 1.51 inches
Denton: 1.39 inches
Ellicott City: 1.35 inches
Pasadena: 1.15 inches
Towson: 0.98 inches
Havre de Grace: 0.72 inches
The problem (if you regard it as a problem) is a stalled cold front draped across the mid-Atlantic states since last week. Low-pressure waves are moving along the front like squirrels on a wire, kicking off showers as they ramble along. It's been great for the grass, and some of it will reach the water tables and continue to raise them up from their winter-drought lows. That's all to the good.
The bummer, maybe, is that the front remains stalled just to our south. And that's keeping us in cool air - maybe 15 degrees below the long-term averages for this time of year - and northeast winds are dragging more cool air and moisture in off the Atlantic. If it feels like we're sailing the North Atlantic out there, that's why.
The rain has been heaviest to our north and west. The NWS has issued flood watches for Washington and Allegany counties in Maryland, and for the Appalachian counties of Virginia and West Virginia
This soggy state of affairs will continue Tuesday, with more cool temperatures and light rain. On Wednesday, the next low to track along the front will lift the front northward as a warm front, raising our temperatures into the high 70s on Thursday and Friday - well above the seasonal norms - with continuing chances for showers and thunderstorms.
The next cold front is due in late on Friday into Saturday, with (surprise!) more showers in the cards. If the forecast holds up, we may finally see a dry day with sunshine by Sunday.
So keep the umbrellas handy and change those raggedy wiper blades. And be grateful we're putting water in the bank for summer.

Even though the deficit keeps eroding, it's not gone yet.

I was worried -- hadn't seen any posts since black thursday; glad you advanced to the next round of 'survivor'!
FR: Thanks. So far, so good.

Frank,
Nice front page piece today! Two days in a row! Glad to see you remained with the Sun, I enjoy your blog and the other informative scientific articles you author, such as yesterdays on the Space Shuttle rescue plan.
FR: Thanks very much. Happy to be employed.

Is there any reason that the Baltimore Sun cannot post seasonal degree days (heating and cooling) as most major papers (Wash Post/Ny Times) do? \
FR: Only space reasons. I'd like to see it, too. I will ask the people who decide these things.
