mattskiva Posted April 24, 2013 Share Posted April 24, 2013 No, DCA's highs for 81-10 were slightly warmer than IAD's (using daily data from both sites), but you wouldn't know that by looking at the official norms. It is almost certainly something to do with how they homogenize the numbers. All of that aside (i.e. not relevant to current discussion), downsloping certainly factors in IAD temperature extremes in summer, right? Also proximity to water (DCA)? It seems like lately IAD has had higher extremes on both the high and low end at times, especially with a west wind. Lower cloud cover maybe too - DCA being closer to the ocean, clouds might hold down daytime maxes and make overnight lows warmer at times. Overall given clear skies and light wind, DCA should be warmer of course. I mean, we're talking 25 miles here so really it shouldn't matter that much, but IAD certainly seems to be much colder at night most of the time, and presumably the same factors might sometimes make it warmer during the day. 200-300 feet of elevation difference should not account for more than a degree of temperature difference at normal lapse rate, yet there is often a much greater difference than that between the two airports.

mattskiva Posted April 24, 2013 Share Posted April 24, 2013 Extended period of mid 60s to mid 70s in spring? If I can't have storms, I'll take this. By "this" you mean "normal"? That sun is HOT today though - wow - feels way different in the sun than in the shade outside. Link to comment Share on other sites More sharing options...
Ellinwood Posted April 24, 2013 Share Posted April 24, 2013 By "this" you mean "normal"? Indeed. 70/50 is good times for April and early May. Link to comment Share on other sites More sharing options...

Mrs.J Posted April 24, 2013 Share Posted April 24, 2013 Beautiful day! And the biopsies came back BENIGN!!! I don't have to wave goodbye to Thelma and Louise! I'd do a happy dance, but it would hurt too much right now. So instead I'm shouting out the happiness. *virtual happy dance* Wonderful to hear when someone gets good news! Especially news like this. Have enjoyed today, got the flower beds watered. Did not have to change from jeans to shorts. Link to comment Share on other sites More sharing options...
Bob Chill Posted April 24, 2013 Share Posted April 24, 2013 Guess the weather is pretty boring There are only 2 canned posts for this time of year unless there are storms. Nice day and not nice day.

Downsloping helps DCA also, arguably moreso. IAD nighttime temps are a little easier to explain - they are at higher elevation, away from water, and sit in a little bowl. Perfect conditions to radiate well and form a cold pool. Link to comment Share on other sites More sharing options...
Bodhi Cove Posted April 24, 2013 Share Posted April 24, 2013 Wonderful to hear when someone gets good news! Especially news like this. Have enjoyed today, got the flower beds watered. Did not have to change from jeans to shorts. Thanks Mrs. J!! Hopefully I'll be able to finally get some flowers planted this weekend. Might even buy a celebratory Hibiscus to replace the one that didn't do too well over the long winter. Link to comment Share on other sites More sharing options...

My BIL and sister work in cancer research and I know of too many people who are either fighting, lost their fight or have beat it. I always say the same phrase Cancer sucks! You get that Hibiscus.

Again, to me that brings in water. IAD has no water to moderate extremes. I don't know that this is the cause, it just seems logical to me.

Bob Chill Posted April 25, 2013 Share Posted April 25, 2013 I'm still vicariously living through webcams of my old stomping grounds. This webcam shot is this morning. It's the backside of Arapahoe Basin. This area wasn't lift served when I lived there. We used to exit the resort through an access gate and ski all over the place. They've had an unbelievable April after a terrible snow year. The resort will most likely stay open until mid-late June or even July if the snow holds.

Son just shared that Jay Peak in VT going to shoot for the weekend of May 4-5. Not bad for a EC resort. He has been on snow every month of year except September. He rode the snowfields of Mt. Washington on first day of summer one year to get his June in and boarded on Mt Hood in OR for his July and August. Link to comment Share on other sites More sharing options...
