A sunny day ... Tuesday

 Satellite image Maryland

With more than 3 inches of rain already on the books for June, the forecasters out at Sterling say we can expect mostly cloudy skies and at least a chance for more showers and thunderstorms straight through Monday. The nearest day rated at least "mostly" sunny comes next Tuesday.

But hey... school is out, and if your old unconverted analog TV winks out today you'll have all the reason you need to get outside and enjoy. Splash in the puddles, maybe.

The culprit once again is a weak cold front hovering to our north. It's expected to push slowly across the region today, setting off scattered showers and thunderstorms along the way as sunshine peeks through and gets the still humid atmosphere stirred up. 

Things will slowly begin to dry a little Saturday, as the front drops down to the Virginia/Carolina border. But we'll still run a small risk of showers and storms. And the wet weather returns Sunday as a low-pressure system moves into the mid-Atlantic and pushes the old cold front back north across the region as a warm front. We won't get things truly cleared out until late Monday or Tuesday, when sunny skies return with highs near 80 degrees.

So far, June 2009 has continued the wet pattern established in early April. But June has been an unusually wet month for some time. Only three Junes of the last 10 have had less-than-average rainfall.

Thirty-year average:  3.43 inches

2009:  3.11 inches  *

2008:  3.70 inches

2007:  2.20 inches 

2006:  7:32 inches

2005:  3.74 inches

2004:  4.17 inches

2003:  6.96 inches

2002:  2.39 inches

2001:  3.58 inches

2000:  5.54 inches

1999:  2.04 inches

* Through 10 a.m. June 12

I expect plenty of mosquitoes from now through Labor Day.

FR: A pretty safe bet, I think. I wonder if the rain explains the nine ticks I found on my person last night after spending a few hours in the woods and fields of Chas. Co. yesterday on a story.

Hi Frank, Wow!! An actual sunny day!!! I'll believe that when I see it...I packed my sunglasses away with the sunscreen thinking I wouldn't need either this entire summer. Thanks!

FR: You're welcome. No charge.

Interesting data set. I wonder if 2009 will continue the three-year pattern starting in 2000. Also, any idea whether the peak numbers in 2006 and 2003 were due to single incidents? I seem to recall missing a week of work in 2006 due to an overnight storm that dumped multiple inches of rain and flooded federal buildings in downtwon DC...

June 2006 was marked by a persistent, week-long deluge as wet, tropical air was pumped north into the region. Can't access the 2003 at the moment.
