No contest at Dulles, as today's high of 70 easily eclipsed the previous record of 63 set in 1995. DCA's 72 didn't break the 1890 record of 76, but was the warmest January 12th in DC since that year.

At Dulles, the current record is just 38, set in 2007. Today's low there is currently 49, and is very likely to hold. In DC, the current record is 47, set in 1890. Today's low at DCA is currently 51, and is also very likely to hold. Link to comment Share on other sites More sharing options...
RodneyS Posted February 1, 2017 Share Posted February 1, 2017 On 1/31/2016 at 6:43 PM, RodneyS said: And January wasn't cold. It was cool. However the 34.9 degree average temperature at DCA, while only 0.3 degrees below the January 1871-2016 DC average of 35.2 degrees, was 16.3 degrees below the December 2015 average DCA temperature of 51.2 degrees. That decline represented the greatest one-month change from December in DC history. The previous record-holder was January 1912, which declined 16.0 degrees from December 1911. (The largest increase was January 1990, which was up 15.7 degrees from December 1989.) This January was a different story at DCA, rising to an average temperature of 42.1 degrees vs 41.8 in December 2016. The January average was 12th warmest of all-time in DC, and was 6.1 degrees above the 1981-2010 normal. Link to comment Share on other sites More sharing options...

It's interesting that the lowest DC daily January maximum is quite a bit higher than either December's or February's (now 65, on February 3, 1927), at a relatively balmy 68 degrees (on January 3rd, in both 2000 and 2004). At Dulles, it's a different story, as January 10th (2002) is the lowest daily maximum temperature on record, at a mere 58 degrees. Today's high of 72 at IAD easily broke the previous February 7th record of 65 degrees, but the lowest February daily maximum there remains 63 (in both 1990 and 2001). In December, the lowest IAD daily maximum is also 63, set on December 19th (1967). Link to comment Share on other sites More sharing options...

Yeah this was a low hanging fruit record at BWI too- appears to be the lowest. Although a high of 72 would break or tie on many other days in February too so it's still an impressive record.

They are currently at three, with many more chances coming up. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted February 23, 2017 Share Posted February 23, 2017 Legit shot at hottest February ever for BWI. As of yesterday the departure was +7.0 which would be tied for 4th with 1932. That will go way up after today and tomorrow. Question is how much Sunday/Monday will knock it down. +8.3 is the magic number, which is where the hottest February (1976) finished. We have five 70+ highs as of today; tomorrow will be an easy win so that ties it at six. Saturday is questionable since the forecast is a high of 68 but if we can overperform a bit we can break the record. Only two degrees away from getting the daily record high today too.

PrinceFrederickWx Posted March 1, 2017 Share Posted March 1, 2017 Another good one: February 2017's average temperature at BWI (44.2 degrees) would still be 0.6 degrees above average had it occurred in March. Link to comment Share on other sites More sharing options...

At Dulles, the February 2017 average temperature of 44.8 is second all-time warmest for meteorological winter, behind only December 2015 at 48.7.

Fozz Posted March 12, 2017 Share Posted March 12, 2017 I'm starting to wonder whether this March will end up colder than not only February, but also January and December. Some of the guidance is predicting some scary cold for the next few weeks, and since the actual met winter months have been so mild, I think we have a shot at March being colder than any of them, not just relative to normal but also in an absolute sense. I wonder how many times that has happened. Probably in 1960, but that sure isn't easy to achieve. Link to comment Share on other sites More sharing options...

PrinceFrederickWx Posted March 13, 2017 Share Posted March 13, 2017 Here you go: March colder than February (7 instances + 1 tie): 1883 (tied), 1887, 1890, 1891, 1909, 1932, 1960, 1984 March colder than January (11 instances): 1876, 1880, 1890, 1906, 1916, 1932, 1933, 1937, 1947, 1950, 1960 March colder than previous December (19 instances): 1885, 1890, 1892, 1896, 1906, 1912, 1914, 1924, 1932, 1940, 1941, 1947, 1950, 1957, 1960, 1972, 2013, 2014, 2015 Surprisingly, 2016 didn’t make the list here- even though December 2015 was the hottest December ever, March 2016 was also 6th hottest March. March colder than all three (3 instances): 1890, 1932, 1960 A few things struck me as interesting- first, it's happened more times in January vs. February, despite February having a higher average temperature. Second, it wasn’t too unusual for March to be colder than January before 1960, then it suddenly stopped happening. Third, our recent December futility/torches are apparent here.

The projected March 2017 average temperature works out to be 44.0, which would be 3.7 degrees colder than February 2017, but 1.9 degrees warmer than January 2017 and 2.2 degrees warmer than December 2016.

Those averages were good enough for a 5th place tie and 3rd place, respectively, all-time in DC. The comparable averages for 1997-98 were 42.5 and 42.4. The warmest astronomical and composite DC winters each occurred during a weak La Nina in 2011-12, at 45.9 and 45.6, respectively. The 2016-17 DCA astronomical winter wound up in second place all-time in DC, with an average temperature of 44.3 degrees. The composite winter averaged 43.7, finishing just behind last year and 4th all-time in DC. Link to comment Share on other sites More sharing options...

The mid-March forecasts for the last half of the month at DCA missed the mark on the low side, as the final DCA March 2017 average temperature was 47.2 degrees. Half a degree cooler than February, but still above the 1981-2010 March normal of 46.8. In fact, it tied 1988 as the 49th warmest of 147 Marchs in DC history. Similarly, IAD averaged 44.2 in March 2017, which was 0.6 degrees below February, but exactly equal to the 1981-2010 March normal and tied with 2011 as the 25th warmest of 55 Marchs in IAD history.

PrinceFrederickWx Posted April 1, 2017 Share Posted April 1, 2017 March at BWI finished at 43.9 degrees which is a +0.3 departure. March did finish colder than February, but only by 0.3 degrees (43.9 vs 44.2). March did finish warmer than December and January though. This March, for the time being, destroyed any chance of getting a top ten hottest year- we’re way, way down on the list now. Link to comment Share on other sites More sharing options...

Are you sure? If you weight the first three months of 2017 equally, the first quarter average temperature at DCA was 45.7 degrees, which is third all-time in DC behind only 1Q 2012 (47.3) and 1Q 1990 (46.3). 1 Link to comment Share on other sites More sharing options...

With all the hype last month about March being colder than February, the cherry blossoms freezing, and the only half-way decent snowstorm of the winter occurring then, I'm guessing 90% of the Mid-Atlantic's population thinks it was an abnormally cold month. :-) 1 Link to comment Share on other sites More sharing options...
