« Howard County tops rain charts | Main | Four storms ranked among top 30 Northeast snows »

March 15, 2010

Hang in there; sunny and 60s by Wednesday

There was more rain on our parade this morning as the departing huge weekend storm continued to spin off Delmarva and throw its weight around. But the slow-moving system is on its way out, NOAAand there is some real springtime weather in the wings.

First, the rain. Forecasters out at Sterling say we could see a few tenths of an inch more Monday and Tuesday before we finally shake free of this mess. Rivers and streams remain high, but the crests appear to have passed most points on the major rivers. 

The National Weather Service still has Coastal Flood Advisories posted until 11 p.m. Monday all around the Chesapeake Bay, with high tides expected to run 1.5 feet or more above predicted levels and minor coastal flooding possible.

Out along the Maryland beaches, the high tides will run 2 to 2.5 feet above normal, with minor flooding in Ocean City.

At Conowingo Dam, the waters of the Susquehanna River reached 22.12 feet at 9:30 a.m. Flood stage is at 23.5 feet. Minor flooding at Port Deposit, Md. begins when the river reaches 23.7 feet. The gauge at Conowingo was reporting 251,000 cubic feet per second flowing past the instruments this morning, a record for the date. 

On the tidal Potomac River, Coastal Flood Warnings are up until 11 p.m. Monday as high tides and the crest of the river flooding reaches the Washington, D.C. and Alexandria, Va. area.

The river flood crest is due in Washington around midday Monday, with Potomac River levels rising as high as 5 feet above normal at Georgetown. Major flooding is forecast at Wisconsin Avenue (chart below). More tidal flooding is expected in Old Town Alexandria

Three days of rainfall at BWI-Marshall have totaled more than 3.6 inches, but as wet as it's been, no records appear to have been broken. Saturday was the wettest day of the three, with 2.31 inches of rain at BWI. That fell short of the record for the date of 2.45 inches, set in 1993.

The total for the month of March so far, through Sunday, is 3.71 inches. The long-term average for March in Baltimore is 3.93 inches, so we're close to the month's quota, with half the month yet to go. The wettest March on record for the city is 8.64 inches, recorded in 1994.

But enough talk of rain. The sun will be out ... not tomorrow, but Wednesday if the forecast from Sterling holds up. The forecast calls for sunshine and highs in the low to mid-60s through Saturday. Showers are possible Saturday night and Sunday.
