MN Transplant

We had a nasty ice storm in MN back in the mid-90s. Was supposed to be 12-18" of snow and the storm wrapped up too much and drove the warm air north. It was fun for a while, until we got a wet basement from the combo of ice clogged gutters and frozen ground. You don't want that at any time of year, let alone January.

I am at 7.25", but half of that is from the last week. IAD to my area to Manassas did not do well, as compared to other spots, in the first half of June.

Fun to break a record. IAD is at 5.48" for more variability.

Four consecutive record max mins at DCA.

So, March is now winter and May is now summer. Yeah, Spring-pril.

Yep. Hottest May on record. IAD will be at least top 3. Didn't check BWI.

Still a toss-up at DCA for warmest May on record.

Both MOS and the NWS forecasts leave DCA with the #2 warmest May on record. It wouldn't take much more to push to #1. Basically, an average of 88/71 the rest of the way is a tie.

Agree, I think we can give up a little simplicity for the sake of better accuracy.

Looks like 3rd at IAD 1970: 31.5 1978: 31.5 2015: 31.8 2014: 32.3 1969: 33.4 Coldest Feb/Mar combo on record though.

We are going to put down some nasty departures as the norms go up in late Feb. Will be interesting to track.

An interesting breakout would be the people that were actually around for 79/83 and forward. I've only been here for the 09/10 storms so Feb 5/6 got my vote, but I would have loved to see how '96 compared.

February 18-19, 1979 - "PDI" - 17.4" February 11, 1983 - 23.1" March 13-14, 1993 - 10.7" February 10-11, 1994 ice storm - 1.4" precip January 7-9, 1996 - "Blizzard of '96" - 23.0" January 25, 2000 - 9.0" February 15-17, 2003 - "PDII" - 17.5" December 18-19, 2009 - 20.0" (me 19.0") February 5-6, 2010 - 22.0" (me 24.7") February 9-10, 2010 - 14.0" (me 9.5") This list is for the Vienna, VA coop station. '83, '96, '09 and '10 in a tight range. The last three I added my measurements.

Good stuff, Rodney.

Yeah, we've had this awesome persistent negative anomaly over most of the continuous 48. (Dec-Feb followed by Mar-May)

The double edited it, so DCA's total was 7.2"

Quite possible that both 1958 storms would have made that list.

Do you have the top-10 on hand, Rodney?

NOAA puts out a monthly climate report. It usually comes out about a week into the next month. http://www.ncdc.noaa.gov/sotc/

Rodney, have you split it out before and after the move to the river location?

We were due for a lull after the run we had in the prior few years.

All-time monthly December high minimums set at IAD and BWI on the 22nd.
