DCA: 11/10 IAD: 10/30 BWI: 11/09 RIC: 11/09 Tiebreaker: 1.08"

50 for my low... DP was 49 but will have to check when I get home whether the temp ever broke into the 40s. (Not a big deal for many of you to be in the 40s, but my location is slow to cool down in Fall.)

The "D" stands for Decadal. ...(for the simple answer.) This isn't bad: https://www.daculaweather.com/4_pdo_index.php

They seem to be forecast to do it again tonight, for a total of 4, should it verify.

Do you mean the 1998 El Nino? Some of our snowiest winters have been since then. Also our coldest February on record. (2015) Snowiest winter on record too (2009-10).

I tried to add the January temps to your post. Hard to get excited about that group with some equally large warm departures. Using BWI normal of 34.3. Not sure what to make of it otherwise. edit: Looks like you have to click the expand button to see them all.

South River higher than it's been in a long time too. No road flooding though. (I cross at MD 450) Only about 0.65" when I left the house, but raining steady since. (since midnight) Windy rain. temp/DP...74/74 f

I'm afraid I'm not too impressed with this, but here you are. You're gonna need a bigger boat....

Cobalt is right, especially looking at their lowest claimed temp as 25f. But, looking at the monthly, only 10 days have positive departure on the avg temp. Eh, the place is weird.

Seems like a weird parameter that I'm not familiar with, but just trying to stay positive... , So for the record....It looks like Feb 2021 was : -0.8 BWI -1.0 IAD -2.2 DCA

Early acorn drop at my little oak forest. Got to wonder if this is related to the cicada invasion, because the trees have really suffered flagging, (as it seems to be called), of twigs and dead leaves everywhere. It was not this bad 17 years ago, but I don't recall what the acorn situation was then anyway. Was wondering if anyone else has noticed the acorns. According to the cicada thread, the flagging is bad for oaks region-wide.

Oh, I'm so surprised. Snowen, the fact that you make this statement shows you're already ahead of the game. Keep it up. And, IMO, the artwork doesn't look so bad at all.

Low of 57

Missed almost everything yesterday and overnight, (a few sprinkles). Now getting some gentle, steady rain for the morning.

Coldest Christmas Day on record in Balto. Zero for the min and 12f for the lomax. Reloaded a month later and IAD recorded lowest temp ever at -18f on 1/22/84 . I believe we had -12f in HoCo, but I'm going by memory, I've lost the written record from those days (I think). ETA: OK, now that you've made me dust off the record book (Balto)....I see that hot Sept 1983 set 5 record high max days: the 6, 10, 11, 19, and 20th. The 11th was hottest at 100f. No other year set so many record temps in the month.

(We tease because we love) IAD was 0.7, which is half of 1.4, so there's that I suppose. And those are the only ones I have readily available. But it just reinforces our idea that BWI is slightly broken, as I think most of us have noticed.

.07" overnight.

If you look at a chart of Atlantic ACE Index, (below hopefully), some of the best winters had low ACE. But I think RaindanceWX is looking at La Nina years only. Which, as we all know, are usually pretty woeful winters for snow lovers, with some exceptions. Looks like the snowy winters of 2013, 2014, 2015 all had low ACE

ACE (Accumulated Cyclone Energy) is a measure of tropical cyclone energy, but I'm probably not the best guy to elaborate except to say this... The way I look at it, things like the number of major hurricanes, or number of named storms, etc. are all subjective, since they'll name a thunderstorm these days. But the total accumulated energy is more absolute, so might be a good measure of how active the hurricane season is.

I guess we talking Atlantic ACE? This chart seems to say we're running ahead of normal for 2021, (as did 2020) That right? I looked at the snow avg calculation and re-did without the highest and lowest (because I feel 1995 is just too anomalous), and still got 20.3" which didn't seem so bad.

Earth's gravity was weaker in those days, so cars weighed less. Actually, I was driving a '68 VW Beetle that winter, (weight < 1800#) so maybe there's some truth there. I do recall looking at certain wheel tracks on the ice of the WSSC reservoir at the Rte 29 bridge. But I did not drive my car on the ice. I think it was a Chevy Vega. (Don't ask how I know.) Kids today don't know the fun they're missing.

KNAK (Navy) is my close station, and the same numbers there are 7.34", Lowest 63, Highest 91. So, living in a woodland, I might miss some rainfall, but I run 2 gauges, and they have agreed within a tenth or so. On the day we hit 59f, I seem to recall that many of our AmWx pals were into the mid 50s. I had 6 90+ days, and KNAK reported 5. KNAK reports avg temp departure of +1.5. BWI claims +3.5. (I don't record this item) What made it a "bad month" was the very high humidity here. Seemed like every day had a DP around 80 for a couple weeks.

August total 4.73" Lowest temp 59, highest 93.
