Yes, in terms of it being the wettest February on record in DC, at 6.98 inches. February 2003 also featured the Presidents Day II snow storm, which dropped 16.7 inches of snow at DCA during February 15-18, and a major rainfall event of 2.27 inches there on February 22nd.

Today is the rainiest at DCA since September 30, 2010, and is currently the 22nd rainiest day in DC history. It could move up a little further, with some evening rain.

Mother's Day. May 8, 2006 reached only 57 at Reagan, but that was on a Monday. Mother's Day 2006 was on May 14th and reached 63.

The rain was followed by the coldest Mother's Day maximum at Reagan since May 14, 1967. Both this year and 55 years ago, it was 58.

I just posted this on the Capital Weather Gang page: I think the most interesting fact about this storm is that it produced the first consecutive days with at least an inch of precipitation at Reagan National Airport since July 2018: July 21, 2018: 4.00 July 22, 2018: 1.15 May 6, 2022: 1.00 May 7, 2022: 1.29

If it's any consolation, you were one of the 10 contestants to outperform the Capital Weather Gang, with a total departure of 5.8 inches at DCA, IAD, and BWI vs. 6.9 for the CWG.

I posted this on the Washington Post Capital Weather Gang page, regarding the 2021-22 CWG snow forecast for DCA, IAD, and BWI: "Very respectable snow forecast. On American Weather Forums, the winner for the smallest departure from the actual snow that fell at the three area airports plus Richmond International was 4.6 inches. Excluding Richmond, the winner's total departure for DCA, IAD, and BWI was 3.3 inches vs a total departure of 6.9 inches for the CWG's midpoint forecast at those three airports. Overall, the CWG forecast would have placed 11th out of 59 entries, if Richmond were not included."

I'm pretty sure that what you list are all hail reports. For some reason, hail seems to have been reported in some years, but not others. Consider that on July 1, 1990, the official Reagan National Airport report is: High Low Prcp Snow 90 69 0.44 Trace

I don't have all the numbers handy, but for Washington DC, according to https://www.weather.gov/lwx/winter_DC-Winters: Latest Snowfall = Trace on May 10, 1906; .5 inches on Apr. 28, 1898

I second the congratulations and commend PFWx for his outstanding job of running the contest for the last several years. With the assistance of his spreadsheet, for which he has already provided me important use instructions, I will attempt to keep the contest running smoothly.

Not so fast -- if there is a huge volcanic eruption that blocks out the sun for several weeks, I still have a chance. And if there are several huge volcanic eruptions, Roger Smith still has a chance. And if Doomsday arrives early, George BM still has a chance.

I'm hoping for a repeat of 1990. That year featured the earliest cherry blossom peak bloom on March 15th. On April 6th and 7th, a 2-day storm dropped 3.8 inches of snow at Dulles.

Looks as though DCA's snow total yesterday was revised up to 0.9 from 0.8.

Tough sledding today for LittleVillageWx, with IUsedToHateCold now in command but WEATHER53 and Rest of Field lurking.

It looks like LittleVillageWx is going to hold on in Richmond, leaving WEATHER53 as his biggest challenger. If on Saturday BWI gets 0.6 inches, DCA gets 0.2 inches, IAD an inch or so, and RIC 0.1 inch, that puts WEATHER53 into the lead, with limited chances for any more snow this season. I would handicap the win probability as follows: LittleVillageWx 40% WEATHER53 35% IUsedToHateCold 15% Rest of Field: 10%

February 2022 at DCA did not come close to matching March 2014 in either of the above categories, but did manage to tie for 20th in official DC weather history in the first one, with 1802 months now in the books. That's still quite impressive, especially since it's the second highest in the last 35 years. You wil note that all of these months are in either January (4), February (6), March (8), or April (3): Highest Average Daily Change in Maximum Temperature March 2014, 12.42 February 1900, 12.11 March 1934, 11.94 March 1923, 11.71 March 1911, 11.58 January 1950, 11.32 March 1935, 11.29 February 1893, 11.04 February 1917, 10.96 March 1907, 10.90 February 1918, 10.89 March 1987, 10.87 April 1965, 10.83 April 1926, 10.77 January 1937, 10.74 March 1890, 10.74 April 1936, 10.70 January 1885, 10.65 January 1890, 10.65 February 1883 10.64 February 2022, 10.64
