Most meteorologists occasionally use the phrase "dominating high pressure" when skies are clear and temperatures warm for a few days. For the high pressure we're dealing with currently, this expression almost does no justice. Centered almost directly overhead, and in no mood or hurry to go anywhere else, this big H on the weather map brings huge doses of sunshine and elevated temperatures to the area for the foreseeable future.

Today (Sunday): We've a good shot at once again adding on to our total of 90+ degree days for this summer today. Loads and loads of sun quickly raise our temperatures from our cool morning lows into the lower 90s during the afternoon hours. Warm, to be sure, but it's nearly September so enjoy it while you can. Winds are light and variable, with sea breezes near the Bay. Confidence: High

Tonight: As warm as our day time highs have been, our overnights have felt relatively refreshing. We'll continue this tonight as relatively low dew points allow our overnight temperatures to dip into the low-to-mid 60s (upper 60s downtown), under mostly clear skies. Winds will be nearly calm. Confidence: High

Tomorrow (Monday): At least Mother Nature waited until we went back to work to really crank up the burners. A blistering sun shows little restraint as our temperatures climb easily into the mid-90s. Granted, humidity is just moderate, but, hot is hot. Winds are once again light and variable. Confidence: High

Tomorrow Night: The heat of the day stays with us longer tomorrow night. While the suburbs are able to cool into the mid-60s or so, downtown likely remains north of 70. Not unbearable, but noticeably warmer than recent times. Confidence: High


Tuesday, Wednesday, and Thursday all keep the heat on high. This commanding high pressure shows no relenting this week and the sun keeps cooking. We'll also be treated to our daily highs in the mid-to-upper 90s, drawing us ever closer to a record number of 90 degree marks. The intense day time heat keeps overnight lows elevated in the District, staying above 70 degrees. Outside the beltway, we'll be a bit more comfortable, with lows able to dip into the mid-to-upper 60s by morning. Confidence: Medium-High

Sigh. When I entered a total for this season of 58 days of 90+ in the Weather Challenge offered by Lori's AM Buzz, which was highlighted by the CWG a few weeks ago, I did it with the best of intentions: greed. (The prize is worth 25 buckaroos.) I didn't intend to wish this upcoming week upon us, but...if my AC goes out, it'll be just deserts. Mea culpa.

So is anyone keeping track of the Atlantic hurricane season this year? How are the predictions holding up? I know the serason is still young, however, seems like it has been pretty quiet out there so far. And when this high pressure sits down on top of the east coast this week, no hurricane has a chance of touching the east coast, I think.

@VikingRider - the Atlantic is anything but quiet right now, with the potential for three major (Cat 3) storms in a seven-day period. The wave train off of Africa is on fire right now, with the potential to throw some Cape Verde storms into the Atlantic. Earl shows a high probability of affecting Mid-Atlantic weather on Labor Day weekend (as well as weather all the way to Boston), and Fiona (currently Invest 97L) is predicted to ramp up by mid-week.

PS - Wish the CWG would do a tropical-specific piece. With all the potential action ahead for next weekend, I think it's in order.

Do any of you think that Earl could possibly turn into another Isabel around here? I sure hope not.

Posted by: Akabang | August 29, 2010 10:21 AM | Report abuse

Earl could possibly hit the Outer Banks head on. Or it could stay well off shore. Too early to say.

I'd say there's not much chance we'll get impacts from Earl around here.. big waves at the beach obviously.

We did a tropical piece Friday and we'll do one tomorrow. We'd only break in over the weekend if a threat is imminent, and it's not.

Oh autumn... Why has thou foresaken me?!? I am craving COOL AIR! sigh...

Good enough for my trail hike, though a bit hot...Still waiting for the inevitable "much-needed-rain" whining which traditionally accompanies these dominating high pressure systems. Dance weather is good up to late in the week, when one or more Cape Verde storms could threaten the area. Hope it doesn't rain for the upcoming huge dance weekend--Friday night at Dulles Hilton, Sunday afternoon/evening at Fairfax Elks Lodge.

thanks CWG. Seems like Earl and the rest of his clan are a long ways off, they could still fizzle out, turn into fish storms, or perhaps hit the Carib and Mex. It's Sunday, it's hot, I know it will be hot all week cause kids are back in school, so I ain't worrying bout Earl til he's on the horizon.

DCA's Monday high: 96, then 95,94, 91 for the 3 days after. Seriously? 0% chance of rain? I didn't think we would get anywhere near 67 days. Just sickening.

Standard alarmist crap from ennepe68. Earl has a LOW PROBABILITY of impacting Mid-Atlantic weather. What forecast are you reading?

"Standard alarmist crap" ?? Sir, I am offended! In no way was my post standard!
