nw baltimore wx Posted July 27, 2011 Share Posted July 27, 2011 Dulles didn't make it Monday I think. 91? Preliminary monthly climate report. I don't know when but maybe a cheapie in the early morning? Maybe it's called preliminary because it's not accurate? On a different note, I'm heading to Death Valley tomorrow. Expected high of 115 Friday. Link to comment Share on other sites More sharing options...

MN Transplant Posted July 27, 2011 Share Posted July 27, 2011 Dulles didn't make it Monday I think. 91° at 9:39am. IAD and DCA's streak began on the 18th, BWI started one day before that. Link to comment Share on other sites More sharing options...

With 10 in the bag, and MOS on board with another 7, things might get interesting. Link to comment Share on other sites More sharing options...

usedtobe Posted July 27, 2011 Share Posted July 27, 2011 I wonder if the number of 95 degree days can equal the average number of 90 degree days. Heck today it's already 91 at dca. It won't reach 95 but probably will get to 92 or maybe even 93. We're blowing by last years July record. Link to comment Share on other sites More sharing options...
MN Transplant Posted July 27, 2011 Share Posted July 27, 2011 I just downloaded the USGS temperature series for the Potomac River at Little Falls back to 1988. Amazing stuff Highest Max water temperature: 7/22/11, 35.4°C Highest Min water temperature: 7/24/11, 32.7°C Highest Mean water temperature: 7/23/11, 33.5°C Link to comment Share on other sites More sharing options...

MN Transplant Posted July 27, 2011 Share Posted July 27, 2011 12z GFS is just ugly. Hot and dry the entire run. Not a day below 90 at DCA, 850s don't drop below 17°C. Just looking at Raleigh's maps, the Euro doesn't drop below 17°C either through 10 days. Per SPC's mesoanalysis, we are at 16°C right now. Link to comment Share on other sites More sharing options...

Looks like we could enter into the top 3 longest stretches of 90-degree heat with the way things are trending. 1. 27 days (July 11-August 6, 1995) 2. 19 days (July 3-21, 1993) 3. 17 days (July 30-August 15, 1980) Link to comment Share on other sites More sharing options...

Ellinwood Posted July 27, 2011 Share Posted July 27, 2011 DCA now at 93... marks 10th day of 93+ in a row. Looks like we'll be able to extend that by another 4 days. (MOS showing 91 and 92 for tomorrow... they had 89 and 91 for today) Link to comment Share on other sites More sharing options...

snownut Posted July 27, 2011 Share Posted July 27, 2011 just a couple hours west and a wee wee bit of elevation . ( that and no concrete or asphalt for for miles) high 86.3 today. which is way way hotter than I like. only 2 days plus 90 this year and 4 other days with a high of 90. hate the heat and glad I don't live where the records are being broken.

(MOS showing 91 and 92 for tomorrow... they had 89 and 91 for today) I suspect we'll be at least 93 tomorrow. MOS tends to under-do these kinds of situations.

Ian Posted July 28, 2011 Share Posted July 28, 2011 GFS looks like it would support 90+ thru most of the period.. perhaps not toward the end but who cares about a d14 forecast anyway Link to comment Share on other sites More sharing options...

Ian Posted July 28, 2011 Share Posted July 28, 2011 what's the record for # of days in a row of +90F? 21 at DC, but we quickly jump toward the top after the next few. Though I don't have "second longest" by yr, which perhaps I should since a yr like 1988 had a 21 and an 18 (which would be second longest on its own).

eurojosh Posted July 28, 2011 Share Posted July 28, 2011 Thought this was an interesting reference from the LWX discussion: IN AN INTERESTING SIDE NOTE - LAST SUMMER I DID A TEMP COMPARISONOF 5 OF THE HOTTEST SUMMERS ON DC RECORDS - 1930..1936..1980..1988.. AND 2010 AND LOOKED AT THOSE SLIDES. IN THE 1ST 4 OF THOSE THERE WAS A SIGNIFICANT COOL DOWN DURG MID AUG. THE XCPTN WAS LAST SUMMER WHICH KEPT UP W/ THE >90 TEMPS THRU THE END OF AUG. 1930`S DC JUL TEMPS ACTUALLY LOOK FAIRLY SIMILAR TO THIS MONTHS - THE AVG HIGH WAS 91.6 (THIS MONTH 92.8) ALTHO THE AVG LOW HAS BEEN 5 DEGS WARMER THIS MONTH. IN 1930 THE HIGH HEAT KEPT UP THRU 8/9...TOPPING 100 ON 5 MORE DAYS. BUT THEN TEMPS DROPPED DRAMATICALLY - AFTR A HIGH OF 102 ON 8/9 THERE WAS A LOW OF 56 ON THE 12TH AND 55 ON THE 13TH. BOTH THE 8/9 HIGH AND 8/13 LOW RMN AS RECORDS FOR THE DAY. THAT MUST`VE BEEN ONE HECK OF COLD FNT. NOW TO WAIT AND SEE IF HISTORY REPEATS ITSELF. Not sure there's any reason to expect such a cooldown - how do the major climo factors this year compare to 1930? Link to comment Share on other sites More sharing options...
Ian Posted July 28, 2011 Share Posted July 28, 2011 There was a brief cooldown in Aug 1980, but it ended up warmer than 2010 going into Sept. I think generally it's hard to sustain neverending heat. I would suspect we get some sort of cooldown in Aug though I would not necessarily bet the house on it. Link to comment Share on other sites More sharing options...

Ian Posted July 28, 2011 Share Posted July 28, 2011 A cooldown from the hottest month on record? I think I would bet my house on it well i guess i meant "cooldown" like "hey it feels cool out there today" or "cool august". usually at some pt in august we get a decent cold front that gives a few nice days at least.
