Rainy February commute (Flickr pool photo by Kevin Wolf)

There is a good chance of rain or storms each day of this week, through Friday.

Normally May is one of the more pleasantly sunny and warm months of the year in the D.C. area. Except for a brief period of warmth today, high temperatures this week will struggle to break out of the 60s.

How do you plan to cope with the cool, rainy, overcast weather this week?

Apparent dust devil during youth baseball game at Quincy Field (photo courtesy Harold Andersen)An apparent dust devil disrupted a youth baseball game in Arlington Saturday afternoon.

The tornado-like weather phenomenon happened around 4 p.m. at Quincy Field, near Arlington Central Library, during an Arlington Babe Ruth baseball game, we’re told.

A witness said the whirlwind sent spectators and players scurrying for cover.

“Three twisters made their way down the third baseball line during a 13-year old Senior Babe Ruth baseball game,” said Harold Andersen. “At first it appeared to be a strong gust of wind but as lawn chairs and full bat bags were carried up into the sky… players, coaches and umpires went running to the dugouts.”

The dust devils eventually dissipated over the library, said Andersen. But seriously, we asked — did one really lift bat bags into the air?

“I actually had a lawn chair lifted out of my hands as I was protecting my face from the flying sand,” Andersen said. “I would swear at least two bat bags loaded with catcher’s gear flew into and over the backstop.”

He added: “One parent yelled out ‘we are not in Kansas any more.'”

It’s not yet clear how much snow this weekend, but don’t be surprised if on Sunday you see a scene like the photos above, from March 25, 2013.

At minimum, forecasters say say a coastal storm will make for a cold, soggy weekend, with a mix of rain and snow. Accumulation seems to be the biggest wildcard.

So enjoy the start of spring and stay warm. Feel free to stay in this weekend and discuss any topics of local interest in the comments.
