A First of June Monsoon Kicks Off Climatological D.C. Area Summer; A Mention of Certain Notable May Weather; Other Stuff Not All There Posted

Early evening deluge as seen from my 5th floor apartment overlooking 16th & U Streets and New Hampshire Ave NW, Washington, D.C., 6:36PM June 1, 2015.


This first day of June (and start of climatological summer) has turned out to be an exceptionally wet one right in the immediate D.C. area -- even "officially" at National Airport climate station (KDCA) -- and into the Baltimore area along with the Tidewater region as well as southeastern Pennsylvania and southern and central New Jersey.

While KDCA has had 2.18 inches of rainfall today through 11PM -- more than the entire month of May when just 1.92 inches fell, which was 2.07 inches below normal -- Dulles Airport climate station (KIAD) missed nearly everything with just 0.04 inches through 11PM.

The deep reds were right over D.C. and, yes, National Airport. Having said that, however, this was not the cell that gave KDCA the 1.42 inches in a one-hour period or 2.04 inches in a three-hour period. Strange are the ways of the KDCA rain gauge and its keepers.

BWI Airport climate station (KBWI) has had 2.45 inches (or thereabouts) through 11PM. For once, though, the Maryland Science Center climate station (KDMH) at the Inner Harbor didn't get deluged -- it has only had 0.44 inches today through 11PM.

All these numbers will change for the final daily totals. I intend to post those as well.

There are flash flood watches, flash flood warnings, and flood warnings in effect in different parts of the region tonight with heavy rainfall still occurring in places (see LWX advisory map below).

A front is slowly sagging through while the upper level pattern is very favorable for this flood of tropical moisture.

I would like to post a full weather briefing including an overview of May -- which was the warmest May on record officially in D.C. at KDCA, running +7.2F above normal for the full month at 73.2F -- to include a discussion of the unprecedented rainfall across Texas and Oklahoma that averaged in many locations in the 15 to 25 inch range*, setting all-time monthly totals, (although the Texas state legislature will probably soon ban any mention of a linkage to climate change). For more information, see these Capital Weather Gang entries: here and here.

*The NWS office in Fort Worth calculated that approximately 35 trillion gallons of rainwater fell on the State of Texas in the month of May (refer to second CWG link).

However, I am not sure I'll be able to post such an entry tonight. I'm rather tired after a long day that included a decently productive workday and a solid three hours at the gym (Anthony Bowen YMCA) that included a 6.75 mile / almost 65-minute jog, an hour of weightlifting, and a short swim plus all the in-between and transition stuff. (Alas, my plantar fasciitis seems to be flaring up in my right heel.)

Tomorrow will not be a gym night. Wednesday is intended to be and Thursday -- in order to avoid pre-weekend drinking that interrupts my Friday -- I'll go to the National Capital YMCA big swimming pool.

As for tonight, I also need to make some dinner before I go to bed.

In terms of other entries, I'd also like to post just a few of the truly odd text exchanges I've had tonight with someone I'm only 95% sure who it is (it's a complicated story). Some of them are literary quality in terms of the wackiness / nuttiness taken to high art and the powerful intelligence behind them.** But this is a separate entry for another time.

Oh, and I'd also like to post some political commentary with links, but that too will have to wait for another time.

**Alright, just one exchange (edited for a few minor punctuation and grammar issues):

[NAME]: "8**962.oc(1). Trust me."

Me: "[NAME], you have an odd relationship with reality."

[NAME]: "Hardy Har har. You, pumpernickel, have no idea where my tech saavy takes me. I am amazing beyond the Christ child!"

[NAME]: "I detest the smell of Irish Spring soap, you doofus ... my sweet pumpernickel."

OK, that's all for now. I'll try to post an update tomorrow night.
