By Camden Walker

Daily shower & storm chances through weekend

* NatCast | Sunrise Photos | Later - Weather Trivia: Think Trillions *

EXPRESS FORECAST

Today: Mostly cloudy. Occasional showers (60% chance). P.M. T-storms? Mid-70s. | Tonight: Decreased chance of rain. Around 60. | Tomorrow: Showers likely. P.M. storms? 70s. | Sunday: Clouds & showers again. P.M. storms? 60s. | A Look Ahead

FORECAST IN DETAIL

Temperatures in the 60s and 70s today through the weekend don't sound so bad, right? However, we'll have clouds win out over sunshine. And showers and thunderstorms will threaten. Daylong washout looks doubtful, and any storms shouldn't be too severe. Yet you will want to tote along that umbrella. Unsettled weather continues into early next week.

Today (Friday): Mostly cloudy skies will prevail. At least it will be warm with highs in the mid-70s. Occasional showers are possible through the day (60% chance a given spot will see rain), with a chance of thunderstorms in the afternoon. It'll be rather breezy -- winds at times around 20 mph from the southwest -- and a bit humid. Where showers do come through, around .25" looks possible. Maybe closer to 0.5" for those who see a thunderstorm. Confidence: Medium

Tonight: The threat of showers and storms should diminish quite a bit from around 7 p.m. until after midnight, leaving most of us with plain ol' mostly cloudy skies, temperatures in the 60s, and a light breeze for the evening. After midnight and toward morning, there's a 30% chance that a few showers will move back in. Confidence: Medium

Well, Friday evening looks like it may be salvageable. What about the rest of the weekend? Keep reading...

Tomorrow (Saturday): Clouds again, and even showers in the morning. And as it gets warmer -- highs genearlly in the 70s -- guess what threatens again in the afternoon? Thunderstorms, about a 60% chance, in addition to the likelihood of more showers. Winds will be light. Confidence: Medium

Tomorrow Night: Continued cloudy, and a 50/50 chance of showers. Lows in the 50s will be just a touch cooler than recent nights. And breezes will be light, out of the northeast. Confidence: Medium

Sunday: Guess what? Yup, mostly cloudy. And a good chance of showers through the day (60-70% chance). Maybe some afternoon thunderstorms. With light winds out of the north, highs will be cooler -- in the 60s. Confidence: Low-Medium

A LOOK AHEAD

For Sunday night our broken record of shower chances continues. Around a 50-60% chance of scattered showers. Seasonable low temperatures can be expected, in the lower 50s. Confidence: Medium

On Monday, high pressure may try to work its way in and give us a brief break in precipitation chances. But that scenario is far from a sure bet. Highs in the 60s should feel somewhat comfortable, I suppose. Confidence: Low

Forecast uncertainty remains high for Tuesday, but it does seem that shower and storm chances could increase again, especially later in the day. This may be our best chance to see some stronger storms, fueled by highs that could reach the upper 70s thanks to an increasing wind from the south ahead of an approaching cold front. Confidence: Low

Updated: Friday May 1 @ 5 p.m.

Comments

Lots of outdoor events this weekend -- Flowermart at the National Cathedral, the Landon Azalea Festival, the season opening of the carousel at Glen Echo Park. Will the off-and-on showers keep you inside? Or will you still plan to be out and about and hope the timing of any rain cooperates?

Still waiting for the day when it's 70 degrees and sunny out...

But not just the one day. You know, the one few day stretch. That happens periodically throughout the season. Cause it's spring.

East of Front Royal, my bucket has about 7/8" of rain in it from this week. Current conditions: foggy, 58.8F.

Another popular event this weekend is the Apple Blossom Festival in Winchester. I haven't made weekend plans yet.

This is that week in May when it rains every day. Seems to happen every year.

It appears this hung-up front and its attendant CRUD are with us for the next ENTIRE week, according to Topper, Tony, Kim and the rest of the gang at channel 9. Despite this, the rain-dance crowd continues to whine about drought. Laura in NW is right; we either see 55 and cruddy or 92 and soggy; never 75 and nice around here in the spiring.

More on Glen Echo--they are moving the swing dance tomorrow night to the bumper car pavilion in order to hold a Viennese ball in the Spanish Ballroom. My undergrad college at Eau Claire State also holds a Viennese ball some time this month.

This rain covers the entire eastern half of the country, and, in Louisville, Churchill Downs is expecting a rather sloppy track for the Derby tomorrow. Bet on a mudder.

This weather, especially the washed-out weekend, is really getting on my nerves. Why is it always rainy in the spring, when temperatures are comfortable, and dry in the summer, when it's 90 degrees out? It's just not possible to enjoy the outdoors in this area. :(
