PrinceFrederickWx Posted July 31, 2015 Share Posted July 31, 2015 BWI's had 16.58" for the summer now, so 8.81" is needed in August to beat the rainiest summer ever record. That's not going to be easy, as 8.81" by itself would be 12th wettest August. More realistic records are:-Another 4.25" in August gives us top 5.-Another 1.81" in August gives us top 10. (these are all to break reocrds, not tie them, so subtract 0.01" for everything to tie a record) Link to comment Share on other sites More sharing options...

However, the DC summer record is a staggering 27.05 inches, set in 1906. But to make the Top 5, DCA needs just 2.94 inches in August. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted August 25, 2015 Share Posted August 25, 2015 Assuming no additional rainfall, BWI limped through July and August to finish at a disappointing 6th rainiest summer, with 19.04" total. Link to comment Share on other sites More sharing options...

Didn't happen, as DCA recorded only 1.16 inches of precipitation in August, 15th lowest in DC history. Meteorological summer total of 18.11 inches still good enough for 13th all-time.

RodneyS Posted September 23, 2015 Share Posted September 23, 2015 With respect to overall temperatures, the 2014 astronomical summer at DCA was a virtual carbon copy of 2013, averaging a minimum of 69.5 degrees and a maximum of 85.8 degrees. And, believe it or not, the overall average was identical no matter how many decimal points you carry it out -- 77.66 degrees to two decimal points, which is the 26th warmest in DC history. The 2015 DCA astronomical summer (June 21-Sept 23) averaged 79.21 degrees -- 5th warmest in DC history. Warmest was 1980, at 81.74 degrees. The 2015 DCA meteorological summer (June 1-Aug 31) was also 5th warmest in DC history, at 79.68 degrees. Warmest was 2010, at 81.24 degrees.

Meteorological summer total of 18.11 inches still good enough for 13th all-time. Yesterday's 1.65 inches of precipitation at DCA was the highest daily amount there only since June 27th's 2.75 inches; however, yesterday's 1.57 inches of precipitation at IAD was the highest daily amount there since June 8, 2014 (1.71 inches).

PrinceFrederickWx Posted November 4, 2015 Share Posted November 4, 2015 Record high watch for Friday at BWI? Forecasted high is 74, record is 77. Forecast is for 79 now so it seems likely. Link to comment Share on other sites More sharing options...
RodneyS Posted November 4, 2015 Share Posted November 4, 2015 Forecast is for 79 now so it seems likely. The same is true for DCA (including historical DC records back to 1872) and IAD, with the NWS forecasts for Friday (November 6th) being 80 and 79, respectively, and the current records in each case being 78. However, the hurdle is not all that great, as the record high temperature from Nov. 6th until the end of the year is 83 for DCA and 81 for IAD. Both of those records were set on November 15, 1993.

Yeah, there's only been six record 80+ highs at BWI in Nov. (none in Dec.), and the last one is 11/8/1975. Monthly record high was 86 on 11/1/1950 so that's not happening either. But it would be neat if we could get another 80+ record. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted November 6, 2015 Share Posted November 6, 2015 BWI has tied the record highest min for the day (63) if we can hold it until midnight. Link to comment Share on other sites More sharing options...
RodneyS Posted November 6, 2015 Share Posted November 6, 2015 BWI has tied the record highest min for the day (63) if we can hold it until midnight. IAD also appears to have had a 63 minimum this morning, which would break the high minimum record of 61 set on this date in 2003, if it holds through midnight.

PrinceFrederickWx Posted November 6, 2015 Share Posted November 6, 2015 79 at BWI! Can we get 80? Yes we can- 80 for the high officially. If the 63 low holds tonight that's an average of 71.5- I think the hottest average day in Nov was 11/2/1971 (83H, 68L, 76 avg) Link to comment Share on other sites More sharing options...

It did hold, and IAD's minimum yesterday exceeded DCA's by three degrees. The last time that IAD's minimum exceeded DCA's was, I believe, April 7th. IAD currently has a departure for November of +10.1 degrees, vs.+ 8.4 at DCA. Link to comment Share on other sites More sharing options...

Blacksburg currently running a +13.3, Roanoke a +11.3. This is crazy. Think at end of month we went backwards one to Sept instead of forward to Nov. Least my wood supply should last at this rate, still haven't built first fire in stove yet this fall. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted November 17, 2015 Share Posted November 17, 2015 If BWI would finish with the current +6 departure, that would be 3rd hottest Nov. I'd say a top 10 hottest Nov. would be a good shot if it weren't for the extended forecast- that's probably going to knock it down a lot. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted November 19, 2015 Share Posted November 19, 2015 BWI missed the record highest min by just one degree... oh well, at least this will still keep us in a good position to hold onto the big positive departure we got going.
