Meteorologists don't expect prolonged 'polar vortex' again this winter

While the chill of the "polar vortex" and some snowy weather are forecast to return this winter, meteorologists don't expect them to have the same persistence as they did last winter, according to two seasonal forecasts issued Thursday.

The National Oceanic and Atmospheric Administration forecasts normal temperature variations in the mid-Atlantic this winter, with no strong climate signals suggesting either colder- or warmer-than-normal conditions. Of course, the forecast was the same last winter, which turned out to be among the coldest in decades.

"Those kinds of really extreme-type winters are pretty much impossible to forecast," said Mike Halpert, acting director of NOAA's Climate Prediction Center, which is based in College Park. "Our outlook certainly doesn’t favor something like that [again]."

The NOAA forecast suggests slight chances of a wetter-than-normal weather along the southeastern coast, including the eastern half of Maryland. It suggests likely wet conditions along the...

Fog and showers forecast early before cooler air moves in

Overnight lows were forecast in the upper 50s and lower 60s, with about a 30 percent chance of showers through midday. Mostly cloudy skies are forecast to continue through Thursday night.

Sunshine is forecast to return Friday, with lows in the upper 40s and lower 50s and highs around 70 degrees.

More sunshine is expected through the weekend, with significantly colder air moving in by Sunday. Highs Saturday are forecast in the upper 60s, but then lows could drop to the lower to mid-40s early Sunday morning, with highs only in the mid-50s Sunday afternoon.

Many areas could hit the 30s to start off the next work week with lows at 40 degrees or below Monday morning.

A tornado warning was issued for parts of Anne Arundel, Prince George's and Howard counties, including Laurel, Beltsville and Elkridge, as a severe storm moved through the region.

The warning was in effect until 1:30 p.m.

As much as 1-3 inches of rain could fall across the region Wednesday amid stormy weather that previously prompted a tornado warning in Washington, D.C. A flood watch is in effect for much of the Baltimore area.

The National Weather Service issued a tornado warning at 12:23 p.m. for southeastern Washington and parts of Prince George's County and Arlington and Alexandria in Virginia. Radar indicated possible tornado rotation near Fort Hunt in Northern Virginia, according to forecasters. The tornado warning was canceled about 15 minutes later.

The flood watch covers Howard, Anne Arundel and southern Baltimore counties and Baltimore City through 8 p.m., according to the National Weather Service. Low lying areas, particularly in urban areas, are prone to flooding,...
