Bob Chill Posted July 21, 2013 Share Posted July 21, 2013 I personally cannot wait for the low dewpoints and highs in the low 70s. I personally can't wait for d10 threats on the euro Link to comment Share on other sites More sharing options...
Ian Posted July 21, 2013 Author Share Posted July 21, 2013 Any idea how this compares to the temp of the Potomac down by DCA? I would think Little Falls would be quite a bit warmer given that it's not tidal and is much narrower and shallower.No clue.. Not even sure exactly where it is heh.

Kmlwx Posted July 21, 2013 Share Posted July 21, 2013 exactly, weather news tends to hype the heatwave and then hype the cool down. MA summers are either hot or less hot most of the time. very rarely dry DP wise, too much moisture this summer to see dramatic drop in DP's ? until sept oct?. We do drought really well, though. All it takes is a decent period of dry with some dry airmasses and we'll be shriveled up and dry before you know it. Link to comment Share on other sites More sharing options...
Ian Posted July 21, 2013 Author Share Posted July 21, 2013 Past the DC/MD line, mile or so upstream from chain bridge. considering how long i've been here i have pretty limited knowledge of the area. my only thought would be that there is probably more flow thru that area? but if it is shallower it might run warm.

I would think Little Falls would be quite a bit warmer given that it's not tidal and is much narrower and shallower. maybe wikipedia can help answer? : Most lotic species are poikilotherms whose internal temperature varies with their environment, thus temperature is a key abiotic factor for them. Water can be heated or cooled through radiation at the surface and conduction to or from the air and surrounding substrate. Shallow streams are typically well mixed and maintain a relatively uniform temperature within an area. In deeper, slower moving water systems, however, a strong difference between the bottom and surface temperatures may develop. Spring fed systems have little variation as springs are typically from groundwater sources, which are often very close to ambient temperature.[4] Many systems show strong diurnal fluctuations and seasonal variations are most extreme in arctic, desert and temperate systems.[4] The amount of shading, climate and elevation can also influence the temperature of lotic systems.[3] Link to comment Share on other sites More sharing options...

It's quite shallow. During drier years late in the summer and into September you can wade across the river above the tide line if you find the right path.

MN Transplant Posted July 22, 2013 Share Posted July 22, 2013 Heat wave officially over? DCA down to 76 this AM The models are all cool by the end of the week, but the GFS has lost its damn mind. 52 for a low on Friday at DCA. Link to comment Share on other sites More sharing options...

MOS is like mid 60s which would still be nice. 87.. should be close to 90 today at least. Link to comment Share on other sites More sharing options...

usedtobe Posted July 22, 2013 Share Posted July 22, 2013 Just finished walking 18 holes of golf. I played really well for 10 and then sort of stunk but did have a nice slurpee to help revive me after the round was over. Also see that we caught our 8th squirrel in the past 3 and half days. Got go out and take him to a new home. Link to comment Share on other sites More sharing options...
WEATHER53 Posted July 22, 2013 Share Posted July 22, 2013 That was a significant week of heat but essentially we had 5-7 weeks of it in 2011 and 2012. Link to comment Share on other sites More sharing options...
