By Brian Jackson

But pesky front keeps slight shower chance around

* Outside Now? Radar, Clouds, Temps & More: Weather Wall *

EXPRESS FORECAST

Today: Partly sunny, p.m. shower south? 84-87. | Tonight: Partial clearing. 63-66. | Tomorrow: Sun and clouds, isolated shower, 83-86. | A Look Ahead

FORECAST IN DETAIL

Less humid air arrives behind the cold front that pushed through the region last night. However, as it stalls just to our south, it will keep the slightest chance for some showers in the forecast due to several weak waves of low pressure developing along it. For the most part though, we'll remain rain-free and the next several days will feature comfortably warm air before we finally get close to breaking the 90 degree mark later this week.

Today (Sunday): Isolated overnight showers and t'storms will be working their way out of the area this morning, leaving us with another fairly nice day in their wake. By breakfast time, we should be high and dry around the District, while the Eastern Shore may still be seeing some lingering showers. In the afternoon, we should have a mix of clouds and sun with highs into the mid-80s. By evening, the front may drift back northward and produce a few more widely scattered showers, likely south of the District. Winds will become out of the northwest at 5-10 mph. Confidence: Medium-High

Tonight: Other than a widely scattered shower mainly south of the metro region in the evening, skies will be partly cloudy overnight with low temperatures in the mid 60s, cooler in the west where clouds may exit earlier. Expect light winds to blow from the west-northwest. Confidence: Medium-High

Keep reading to find out if summer heat will make itself known this week...

Tomorrow (Monday): Tomorrow's forecast is a bit trickier due to proximity of a weak disturbance moving along the front stalled to our south. I'll call for a small chance for an afternoon/evening shower (20%), but otherwise expect partly to mostly cloudy skies and highs in the lower 80s. Winds will be variable early, becoming more out of the west towards evening. Confidence: Medium

Tomorrow Night: Showers will still be within the realm of possibility overnight but for the most part the area will remain rain-free. Skies will begin to clear towards morning and overnight lows will be in the mid-to-upper 60s. Confidence: Medium-High

A LOOK AHEAD

Unseasonably dry air returns to the region Tuesday. High pressure building in will provide us with the nicest day of this week. Skies will be mostly sunny and afternoon highs will be quite comfortable in the mid-80s. Clear skies continue overnight, with lows in the mid-60s. (near 60 in the cooler suburbs). Confidence: High

Wednesday will begin to feel more like summertime around here. Southwesterly flow will begin to pump more moisture and higher humidity into the area along with increasing warmth. Expect sunny, hazy skies during the day and temperatures climbing into the upper 80s. Confidence: Medium-High

Fortunately last night's weather turned out to be a light, gentle rain during the early evening and not the dangerous lightning predicted by some for Saturday afternoon/evening. I believe we had just enough to wet the ground, nothing more.

We also had a nice Rockabilly Jam at the Spanish Ballroom, and the big concert at Nationals Park undoubtedly came off without a hitch. Now all we need is a contending baseball team or two. Do we have to keep contenting ourselves with continued last-place finishes??? Getting contenders in town will work wonders for attendanceat both Nationals Park and Camden Yards...just ask folks in Milwaukee and St. Louis.

One bad item: I had to be picked up at home instead of my original plan to take Metro to Dunn Loring...thanks to GM Catoe's decision to terminate half the Orange Line trains at West Falls Church instead of sending them on to Vienna! If you REALLY want to get people out of their cars and onto transit you shouldn't be making things hard for us with continual "trackwork" delays and construction projects tying up Metro lines for FOUR YEARS, when such projects could probably be done within three to six weeks. Does it REALLY take that long to renovate a portion of the Red Line; my understanding is that NONE of the area affected by the recent accident is involved in this process.

National hit 90 today, 4th this season (including the one pre-summer in April). BWI/IAD also 90. Downsloping winds outdo cold front.
