yoda Posted July 16, 2013 Share Posted July 16, 2013 Yoda*, there is no benchmark...we've done it with 88...maybe even lower...we are fine...not saying we will hit it...there are of course other factors....but our current temp is by far no disqualifier.. Ah ok... thought there usually was a watermark we would like to be at to possibly reach 100 Link to comment Share on other sites More sharing options...

87storms Posted July 16, 2013 Share Posted July 16, 2013 i feel like summer has been near par for the course so far. probably more humid than normal and maybe very slightly above normal, but nothing to get disappointed about. if i didn't follow the weather much i probably would have thought this was a pretty typical summer. though this week may change my thinking a little.

chris87 Posted July 16, 2013 Share Posted July 16, 2013 my guess is yes, but I don't know...we were at +16 last hour...but +19 was very close by I'm sure there's a case, 20C at 850 fully mixed only gets you to about 95/96 w/o downsloping -- I looked at the days > 100 last year and the lowest 00UTC observed 850T was 20.8 (on July 6 and July 17) -- using the 0z IAD sounding which should represent pretty closely the diurnal max for 850T Link to comment Share on other sites More sharing options...

chris87 Posted July 16, 2013 Share Posted July 16, 2013 we are around 18.5 now..we might just make 20 later... yeah, 100 seems a bit out of reach today -- i still like thursday as our best shot at 100 -- maybe Friday too Link to comment Share on other sites More sharing options...
87storms Posted July 16, 2013 Share Posted July 16, 2013 it actually doesn't feel all that bad outside, so far, to me at least. i wouldn't recommend playing a few sets of tennis right now, but i was able to walk around for a few blocks and not sweat profusely.

Low temps have been on the warm side, which is why our overall temps have been above average. Highs have been pretty much right around average.

Ian Posted July 16, 2013 Author Share Posted July 16, 2013 we even suck at heat this summer..the only thing we are good at with weather is absurd lows gfs still has some 21C 850s over parts of the area thurs and fri. Link to comment Share on other sites More sharing options...
chris87 Posted July 16, 2013 Share Posted July 16, 2013 we even suck at heat this summer..the only thing we are good at with weather is absurd lows it's predictable though -- you have a vegetation canopy that is experiencing no water stress and a humid airmass, takes a lot of energy to warm.

mattskiva Posted July 16, 2013 Share Posted July 16, 2013 we should probably ban OBS from all the auxiliary stations since they are pretty much all bogus All the PWS out here are reporting high dews also. Maybe it has something to do with the LWX equipment surrounded by concrete in an open field while most of the outer stations are in more rural areas - evaporation from the vegetation raising the dewpoint?

mattskiva Posted July 16, 2013 Share Posted July 16, 2013 Interesting - dews peaked around noon and have plummeted, now down to 93/71 which is identical to Dulles. JYO seemed to do the same - much higher dews earlier but have now dropped to an only mildly disgusting 70. Link to comment Share on other sites More sharing options...
