A. Camden WalkerIt's been a week of temperature swings and we have one more today, this time toward the warm side and with humidity, too. What had looked like a spectacular weekend still looks pretty promising. But clouds may be more of a factor than originally expected if the cold front responsible for today's thunderstorm threat stalls closer to the area than first anticipated. Still, the weekend should provide plenty of pleasant outdoor time, with comfortable conditions on tap for tomorrow's Preakness up in Baltimore.

Today (Friday): Unless you were born in Miami, Houston or New Orleans, today's humidity will feel unnatural for mid-May. Or at the very least uncomfortable, especially combined with warm highs in the mid-to-upper 80s. The sun tries to peek through mostly cloudy skies at times as breezes blow around 10-15 mph from the southwest, and we run a 40% chance of afternoon thunderstorms. Any storms that do form have the potential to turn quite strong or severe, possibly with strong winds and hail. Confidence: Medium

Probability: 40%
Coverage: Isolated-Scattered

Tonight: Skies likely remain mostly cloudy with evening storm chances staying around 40%. Any storm activity should hopefully die out after midnight. Lows cool to the low-to-mid 60s inside the Beltway, perhaps some upper 50s in the traditionally cooler suburbs. Drier air behind the cold front slowly filters in overnight on breezes from the west/northwest around 10 mph. Confidence: Medium

Keep reading for the forecast into next week...

Tomorrow (Saturday): Clouds may linger for a time in the morning. But the sun should shine more brightly as the the day goes on. A moderate breeze (10-15 mph) from the northwest keeps the humidity low, yet we'll still enjoy mild highs in the upper 70s. A great day for flying a kite or catching the Preakness in Baltimore, where similar conditions are expected. Confidence: Medium-High

Tomorrow Night: Partly cloudy with comfy sleeping weather -- lows in the 50s with humidity still on the low side. Open the windows! Turn off the A/C! Confidence: High

Sunday: The forecast gets trickier Sunday mainly due to an uncertain cloud forecast -- we'll call it partly sunny for now -- but we also can't rule out an isolated afternoon or evening shower. Low-to-mid 70s for highs should be nice enough for a walk along the C&O canal or around downtown. Wear that sunscreen, though, whether it's cloudy or not. Confidence: Low-Medium


Partly cloudy Sunday night with a slight chance of a shower. Temperatures remain pleasant with lows mostly in the mid-50s. Confidence: Medium

What could be a juicy low-pressure system threatens to bring periods of rain late Monday & Tuesday. Both days should be mostly cloudy with highs in the 70s to upper 60s. Confidence: Low-Medium

@Camden: So all the wind is on Saturday, with nearly nothing on Sunday? NWS posted a Small Craft Advisory for Saturday calling for gusts to 25mph, and Sunday listed as North winds at 5mph. :-( Any chance we might do a tad better than that on Sunday?

Even though it is cloudy, at least the sky is a little bright, right? Doesn't that help (be less depressing)? :)

You can't be too depressed if it's warm & you're planting beans & okra.
Welcome to sauna Friday. Don't forget to bring a towel.

Yes, better mood today thanks to sun. Or maybe it's just because it's Friday. LOL

Thanks, Camden.

hey --sg: I am so sorry the darn comments don't load right some days. I didn't see your comment till now. And I believe Sunday..well, I am skeptical of much of a breeze at this point. Sorry!

I DO NOT like this forecast for Tuesday the 18th as I'm scheduled to have my remaining wisdom teeth extracted at 4 PM that afternoon.

As everyone knows, low pressure and bad weather make pain more painful. I scheduled the surgery for the 18th because the usual Tuesday night Clarendon Ballroom swing dance got bumped for a "private event". So what happens??? eemes the generally anti-Bombo "much needed rain" crowd picks the day of my wisdom tooth surgery for a pain-increasing "juicy low-pressure system"! Enough of this! Can't someone have the mercy to give me a pain-suppressing high-pressure system instead?

Excuse me...the previous post should read as corrected..."Seems the generally anti-Bombo 'much-needed rain' crowd..."

And, believe you me...I'm still FURIOUS that I can't get better weather for my major dental surgery...I think I can get to the oral surgeon OK, but, thanks to the low pressure, recuperation will be that much more painful. Would much prefer a high barometer for this type of oral surgery!

Bombo47, a simple 9-letter word should allay your fears Tuesday about dental pain.


And perhaps (?) the dentist can give you something to take home with you after the initial effects of the shot wears off...maybe a strong NSAID anti-inflammatory. Indomethacin works well on may types of imflammatory pain.

Looking at the radar, I see what looked a line of showers coming thru WV and basically dying. Is that a sign of things to come later today?

Posted by: ThinkSpring | May 14, 2010 2:00 PM | Report abuse

Camden, Looking at your forecast, my guess is that we're not going to see cooler daytime temps for a while (i.e. less than mid 60s). We've had some flip flops but my take is that the heat, and increasing humidity, is now here to stay. Do you think that's the case?
