Sunshine until rain returns late Wednesday
Noticed a few cars during the commute this morning that had some snow on their hoods and roofs. We had only a sprinkle of flakes, or sleet, on the WeatherDeck. But some locations across Maryland really did get measurable snow overnight as the rainstorm pulled away and dragged some very cold air down from the north behind it.
The National Weather Service is reporting 2.5 inches on Frostburg, Md. The highest totals were in West Virginia, topped by 6.7 inches on Bayard, Grant County. None of that, of course, compares with the foot or more from the same storm system, recorded this morning in portions of northern New England and northeastern Canada (AccuWeather.com map, left; depths in centimeters).
Around here it was just rain, falling, it seemed, in a series of heavy showers, interspersed with drizzle. As predicted, the amounts were typically in the 1-to-2-inch range. But some locations in Harford and Montgomery counties topped 2 inches. Here's a sampling:
Gaithersburg, Montgomery County: 2.38 inches
Somerset, Montgomery County: 2.3 inches
Darlington, Harford County: 2.25 inches
Emmittsburg, Frederick County: 2.0 inches
Glen Burnie, Anne Arundel: 2.0 inches
Reisterstown, Baltimore County: 1.35 inches
Pimlico, Baltimore City: 1.25 inches
Here are some more rain totals from the CoCoRaHS Network. There is a Flood Watch up this morning for the Monacacy River in Frederick County as the heavy weekend rains continue to drain off. Only minor flooding is being reported.
If you liked Sunday, you'll probably like Thursday, too. That's when forecasters expect the next rainy cold front to pass through Central Maryland. We'll have sunshine and seasonable temperatures until then. And look for more gusty weather today.
But by Wednesday, a storm brewing in the Great Plains will begin to influence our weather. Like the weekend storm, this one will begin by dragging more warm, moist air up from the Gulf in the broad, counter-clockwise flow around the low. That will increase our cloud deck on Wednesday and raise our rain chances during the afternoon.
During the overnight period from Wednesday into Thursday, the forecast boosts the predictions to "moderate rain." But, like we saw on Sunday, that comes with some periods of heavy rain, as well. More stream flooding is possible.
The cold front finally moves through the area sometime on Thursday, followed by a rush of cold air out of the northwest - around the backside of the low. Once again, as we saw this morning, that could mean some snow in the mountains into Friday morning.
The weekend, at least, looks sunny and mild for the moment, with highs in the 50s.
