Forecast: Cool Day Begins Sunny Stretch

By Dan Stillman

Say it ain't so! ... back to sub-par weekends?

Remember, back before that beautiful holiday weekend of ours, when the repeating pattern was lovely mid-to-late-week weather followed by increasing clouds and rain chances over the weekend.

Uh, yeah. It's ba-a-a-a-ck.


Becoming mostly sunny. Upper 60s to near 70. Our brief bout with higher humidity is over. Today will be noticeably less humid than yesterday. But the price will be cooler temperatures. Even after clouds clear out and skies become mostly sunny by late morning or lunchtime, afternoon highs will only make it to the upper 60s, maybe touching 70. Winds, from the north, should start out around 15-20 mph in the morning, decreasing to near 10 mph for the afternoon.

Tonight, clear and cool with lows near 50 downtown, mid 40s in the burbs.

Confidence: Medium-High

Keep reading for the forecast through the weekend, and check back later this morning for our 2008 summer outlook.


Mostly sunny. Mid to upper 70s. Now this is good stuff! ... After a crisp morning, especially outside the Beltway, highs will climb to the mid to upper 70s along with mostly sunny skies, low humidity and light winds. Overnight, not as cool with lows in the upper 50s downtown, low to mid 50s in the burbs.

Confidence: High

Friday brings more sunshine, maybe with an increase in clouds during the latter part of the day, and highs in the upper 70s to near 80. Confidence: Medium-High

Showers and thunderstorms are a definite possibility on Saturday and Saturday night as a cold front closes in from the northwest. Early indications are that some storms, should they materialize, could be strong or severe. Under a mix of sun and clouds, Saturday's highs should make the 80s with rather high humidity. Confidence: Medium

Will the front linger in our vicinity on Sunday? It very well might, though the chances for showers and storms should be lower compared to Saturday. Looks like upper 70s to lower 80s for highs. Confidence: Low-Medium

SPC didn't include the Saturday threat on the new Days 4-8 Conv. outlook. I've noticed that they seem to drop threats the next day even with fairly good model agreement. Any one know why they do this?

Also, just took at look at the BUFKIT from the 00z models and still looking impressive. GFS spits out near 2500 CAPE it looks like.

No rain for Vintage Virginia Wine Festival on Sun either. :)

I'm going to consider requesting a flexible work week, so that I can work on weekends when it rains, and have off on the sunny mid-week days.

One has to figure that in the days 4-8 outlook, there is a 30% or more probability of severe weather and that it's not highlighted over our region for Saturday. But the odds are greater for strong-severe on Saturday than last night given the better instability and greater shear parameters.

But the cool weather cannot last forever, along with the storm chance comes a warmup and a surge of more humidity just in time to wrap up May and begin June.

At least I will be retiring effective May 30 ~ so I can stay home when it rains (except on dance nights!).

My NRECA e-mail address will cease to be active effective May 31. My new Gmail address will be:

I may also be getting Comcast internet with e-mail at some point in the near future. This depends on when Dell delivers my new desktop computer and I can get installation--likely some time between May 30 and June 3.
