Forecast: Blissful Weekend Weather Wise

By Jason Samenow

Though dry, next week looks wet

* Can Wind Farms Change Weather? | Alignment on Tornado Advice*

Today: Partly to mostly sunny. 83-86. | Tonight: Partly cloudy. 59-66. | Tomorrow: Mostly sunny. Mid-80s. A Look Ahead


Considerable sunshine and low humidity will grace the region this weekend in the wake of the sticky weather that concluded the work week. Though pleasant, it will remain dry while lawns and gardens grow increasingly parched. Most of the region has received less than 0.25" of rain all month. However, early indications are that next week's pattern will be favorable for wet weather. So enjoy the dry weather while it lasts.

Today (Saturday): A partly to mostly sunny day is in order as high pressure builds in from the west. Humidity levels will fall throughout the day even as the warm July sun warms us up into the mid-80s. Winds will be out of the west at around 10-15 mph. Confidence: Medium-High

Tonight: With high pressure continuing to build into the area, expect a mainly clear night. Some of the cooler spots will dip into the upper 50s while locations closer to downtown fall to the mid-60s. Confidence: Medium-High

Keep reading for the forecast for tomorrow and into early next week...

Tomorrow (Sunday): More high pressure and more sunshine tomorrow. With a light breeze from the north at 5-10 mph, the air will remain pleasantly dry, as temperatures climb into the mid-80s. Confidence: Medium-High

Tomorrow Night: The atmosphere will begin to moisten up as winds start to come around out of the east. The modestly more humid air and slight increase in clouds will keep overnight lows a little milder, with low 60s in the cooler suburbs and upper 60s downtown. Confidence: Medium


We may begin to feel the effects of a juicy Bermuda High Monday that will steer a good dose of moisture over the region during the week. Under a mix of clouds and sun, highs will just be in the low-to-mid 80s, but humidity will continue rising. A few showers and storms cannot be ruled out (30% chance), especially late in the day. Partly cloudy overnight, with lows near 70 (mid-60s cooler suburbs). Confidence: Medium

Mostly cloudy and humid on Tuesday, with a 40% chance of showers and thunderstorms. Highs will probably be in the mid-80s. Confidence: Medium

.67" much needed rain yesterday.

It appears that the combination of a trough to our west and strengthening HP in the Atlantic will open the doors of both the Gulf and Atlantic and allow a very moist pattern to establish itself over the region.

The next two to three weeks look to be as wet as the last three have been dry and tropical system contribution is possible.

Frenetic and fretful times are ahead for El Bombo!!!

Boy oh boy!!! My keyboard stalled or something while I was trying to respond to AugustaJim's pro-rain diatribe above...However, there are no Tuesday night dances at the Clarendon Ballroom during August in addition to one Friday night with no dance at Chevy Chase, giving me more evenings at home next month anyway.

The low humidity has been rather nice, and it will be sad to see a return to the conditions of this spring, when everything was wringing wet and gloomy. It will be nice to get the sunny dry days of autumn back, unless the weather patterns set up for an autumn as gloomy as this spring was. However, I guess Jim and the other rain buffs around here prefer fungus and mold over autumn color anyway.

As for the tropics, that type weather has been relatively quiet so far. Sometimes this time of year we get "pure tropical" air from the southeast with nice weather but very humid conditions; maybe that's what AugustaJim is talking about...

El Bombo:
Hello again my fairweather obsessive friend.

I enjoy lush, green lawns during the summer and bright reds and gold during the autumn.

Neither can be achieved with sparse amounts of rainfall during June to August as you erroneously seem to believe.

Lawn watering is a joke and waste of water unless you are well versed on the subject, have a very small lawn or very elaborate sprinkling system.

Autumn colors are dependent on sufficient moisture during the mid and late summer.

BUT....I am very happy that your DANCE interuptions will be somewhat limited during August!!

Bring on that 4-6 inches of evenly distributed rain during the next 30 days!!!
