Showers will clear decks for fine holiday weekend

It's a long way 'til Friday, but if the National Weather Service forecast holds up, we can look forward to some terrific weather for the long Memorial Day weekend - sunny skies and seasonable highs in the 70s. But first we have to sit through a couple of days of showers as a Canadian storm system sends a series of weather disturbances across the region.

Here's the deal. It's going to be a bit cool, but sunny today, as high pressure builds behind the cold front that passed by yesterday. That front is what brought us all the showers, and the dramatic clearing late in the day. Here's the link to near-real-time data from The Sun's weather station at Calvert & Centre streets.

The sunny skies and gusty winds today will yield to increasing clouds and a chance for showers late tonight. The low over southeastern Canada is turning counter-clockwise like a water wheel, and it will deliver the first packet of showers tomorrow, with rain likely in the morning before it rotates out to sea.

After a short break and a chilly night in the 40s, the next package arrives on Wednesday, with a renewed chance for showers into Wednesday evening. (No risk of an overnight record low; the BWI records are still in the 30s at this time of year.)

But then the Canadian low that's driving all this drifts away, and we come under the influence of more Canadian high pressure, forecasters out at Sterling assure us. That will mean cool, clear, dry weather from Thursday right through the long weekend. They're forecasting highs in the mid-70s - at BWI - about right for this time of year. 

Friday's a comp day for me. They had me working Sunday writing obits and covering a rained-out Studio 6001 art show in Mount Washington. (That's Sun Photog Ken Lam's photo below. We both got pretty wet out there, but the show's been rescheduled for this Sunday noon to 5 p.m.)

So now I'm looking at a four-day holiday weekend ahead with perfect weather. Hoo-wah! Anybody have any suggestions for how we should enjoy the weather this weekend? Or will the old hammock be just about right?
