Mrs.J Posted July 18, 2013 Share Posted July 18, 2013 The main solar panels for my WV place were on the barn roof and back fed the house electric. so in my case they had little effect. Seriously though it will vary depending on the install method, if they are rail mounted at least 6" above the roof surface. Tighter mounts trap more heat underneath (6" minimum I recommend since air flow and cooler panels perform better). There is know doubt the roof and attic area below the panels will be cooler. Send me a photo of your system when the installation is complete. And get a measurement or two of the attic temperatures now and then do that again on a comparable day after installation. Thanks! 80/84 HI 85 currently. Heading up to the lake this morning. Thinking we will be spending our whole time in the water with plans to be leaving around 12:30 as I have to pick up a friend of one of my daughters. Should be a good time to bail.

chris87 Posted July 18, 2013 Share Posted July 18, 2013 it'll be interesting to see if we do indeed max out 850s tomorrow and fri. almost get the sense of the subtropical high becoming "rooted" as a continental air mass as it sits around. im not sure i agree with the multiple comments about heat underperforming though. as far as i can tell looking at guidance as its progressed every day has hit the high end of reliable guidance. compared to an upper ridge like this in past years maybe but as noted the origins and pre-conditions were considerably different. just as a clarification -- I used "underperforming" not as a metric relative to guidance (which has been fine; see 2 days ago when i said that the low level thermodynamics didn't support 100 on tues/weds) but from a meteorological standpoint relative to how the magnitude of the mid-level anomaly didn't necessarily translate to a low-level anomaly of the same magnitude -- the current observed land surface-atmosphere coupling and the antecedent airmass favored a scenario where the low-level anomaly has been slow to strengthen (relative to the mid-level anomaly) -- not sure I know the relative weight of which played more of a role (the antecedent tropical airmass or land surface-atmosphere coupling).

MN Transplant Posted July 18, 2013 Share Posted July 18, 2013 87 at 9! 80 for the low again. Barring any storms we are going to have 4 in a row. Tomorrow's low may be more like 82. Link to comment Share on other sites More sharing options...

Ian Posted July 18, 2013 Author Share Posted July 18, 2013 80 for the low again. Barring any storms we are going to have 4 in a row. Tomorrow's low may be more like 82.Tops was 2 in row prior to 2011. Now could go 4,3,4. Could just be some 79s I guess.. Tho no doubt the return rate is much greater lately.

Tho no doubt the return rate is much greater lately. My question is - we know that the UHI exists, but is it really that much different than it was a couple of decades ago? Alternatively, have the extremely warm summers of the last 4 years affected the river temperatures to the point where they are driving the DCA lows upward.

Alternatively, have the extremely warm summers of the last 4 years affected the river temperatures to the point where they are driving the DCA lows upward.Year to year highest temps have been remarkably consistent over history but our highest lows are definitely on the way up overall. The last few summers have had some whacky things happen. I keep thinking it's just a blip though but if not something is different. While unimpressed with 90+ so far this year I think this heat event is pretty solid. Link to comment Share on other sites More sharing options...
Subtropics Posted July 18, 2013 Share Posted July 18, 2013 1 degree above yesterday at this time. Glad to see another 80 low. Hoping for no storms to keep streak in tact. Link to comment Share on other sites More sharing options...
MN Transplant Posted July 18, 2013 Share Posted July 18, 2013 I think those are all good points and worth discussing, but at the same time Chris's explanation is a factor too for this particular outbreak lows this morning ORD: 77 MDW: 79 MKE - 79 MSP - 80 Minneapolis has had a grand total of one low temp since the Dust Bowl that was higher than 80°. July 4th last year. This is definitely an aggressive airmass as far as lows are concerned. Link to comment Share on other sites More sharing options...
ravensrule Posted July 18, 2013 Share Posted July 18, 2013 I believe it is 5 dead this summer, not this heat wave. I could be wrong I thought on channel 11 they said 5 dead from this heat wave. Link to comment Share on other sites More sharing options...
astarck Posted July 18, 2013 Share Posted July 18, 2013 1 degree above yesterday at this time. Glad to see another 80 low. Hoping for no storms to keep streak in tact.

MN Transplant Posted July 18, 2013 Share Posted July 18, 2013 The "cool-down" this weekend is starting to look a little bit lame, and pretty much dependent on clouds/precip. A 4th consecutive Top-10 warmest July is in play. Link to comment Share on other sites More sharing options...
