Yep. I've had your yearly total of rain just since May 1st BTW.

I can't imagine lows bottoming in the 30s around here in July as a relatively normal thing. Global warming is definitely in play here, but I wonder if it's also a heat island affect, even though we are further from the city areas, how much of an affect have we seen? Also airborne pollutants trapping heat and not allowing it to radiate off (aside from CO2) And higher dewpoints would likely correlate with less radiational cooling.

Real winners north and west of the city.

Do you really want to give Kevin shit when you have this mid month gem?

I know a lot of our days in past summers, the dewpoint gets ticked downwards a bit by downsloping winds. Seems perhaps that has been largely missing this year?

Doesn't Mt Joy have about 35" for the year so far? Which is nuts since it's 27 miles away. Sent from my SM-G970U1 using Tapatalk

Anyone know if this will be the clear #1 for highest average dew point / humidity in dc on record? Seems like half the days were 75+ for much of the day - even in these parts that seems unusual? .

Nighttime doesn't matter to me but then again I'm cuddled up in my room with the a/c on 62.. if i didn't have it I would say this July was miserable but thankfully fortunate enough to have it..

Catoctin Creek is running pretty low again. This area could use a deluge at this point, but the models aren’t showing a whole lot from this event for the rain shadow zones. Hopefully we can at least get a line of cells to move through.

Whatever fits ACATT agenda

I, for perhaps one, am psyched for this impending rain. Well timed, while also well needed. Just commencing here... showery and vaguely convective N of the more obvious downpours sliding up ENE out of CT ...ranging to strata rains over Upstate NY and CNE. This is occurring through 13z tomorrow morning, and then the moisture fields/sigmas make it appear as though we actually fracture the ceilings and sun wins out over the course of the afternoon hours, NW-SE, tomorrow. It's a work day and night ... this is when we ...or I, prefer it. Wouldn't mind a solid 3" soaker but as me grandmammy always used to say, 'beggars can't be choosers'. Saturday still projects to be the very best weather in terms of subjective consensus, this summer ...or any summer, can provide on Earth. If you want something better... I don't know, go to "Pandora" or something I guess. It's like regional mean of 78/50, under the last days of solar max irradiance, thru 100 mi type visibility air moved around by caressing zephyrs. Altho..hm, not sure of Michigan smoke but cross that bridge.. . Sunday looks pretty much the same, too. Jeez

Humidity is what leads to our hottest months relative to normal as a mean temperature. Like Brewbeer said, it’s probably the most AC usage we’ll see. If you cannot cool off at night, that almost has more societal impacts than daytime. People expect the daytime to be hot/warm. But if it’s 75F all night… that’s when things get real abnormal. I don’t get the tossing of overnight summer warmth like it’s not important in this discussion.

Some loud thunder and heavy downpours earlier this morning with .33 thru the tipper so far, 67/66.

Impossible to really say at this point. Encouraging that the models have storms surviving east of the city but we just have to see how it evolves.

So basically summer doing what summer does.

radar must be wrong. we were told it was all going south of CT

Currently I'm sitting at 21.32" for the year. I should be at 25.76". For July I'm at 3.68", I should be at 4.76". So I'm definitely hoping for 2" today to eat into my 4.45" rain deficit. Sent from my SM-G970U1 using Tapatalk

Yeah it's gross out. Front please move through on time.

Oh so not the hottest or top 5…or even a top 10 lol. WTTTH

A very warm July. A heat wave at 1K at the end. Dry in terms of precip but super humid We take

From the 7/31 0z HREF:

This July was a continuation of the rural spots in NJ not dropping below 50°. Prior to the big increase of our summer temperatures in 2010, they would regularly have the monthly low temperature in the 40s. Before 1960 it was typical to get into the 30s in July. So the July lowest temperature has risen by around +12 since 1893.

From CTP: Southern/Southeastern PA/Lower Susquehanna Valley Farther south, this area is more removed from the jet-streak dynamics to the north. However, this region is closer to the deepening surface low with strong surface-925mb southerly theta-e advection directed into the southeastward advancing surface front. A tropical air-mass (depicted by 2-2.25" PWATs and low-mid 70s dew points) will coincide within a warm sector that becomes increasingly unstable (MUCAPE between 1,000-2,000 J/kg). It is worth noting that SST anomalies along the Mid- Atlantic and Southeast coasts are well above normal too, acting as an abnormally rich moisture source for southerly low-level flow to draw from. By this afternoon, low-level WAA into the front will support storms enveloping the region with additional storms from the Laurel Highlands/south central Alleghenies tracking east. Modest vertical wind shear aloft will also support organized clusters of storms, some of which will have the potential to backbuild and train between the I-81 and I-95 corridors into tonight. Latest 12Z HREF guidance shows 24-hr probabilities for >3" of rainfall are high (>70%) across southeast PA. Just as concerning is this same region sports 30-60% chances for >5" of rainfall with 24hr PMM/LPMM values close to the ensemble maxima approaching 8 inches.

One last flood watch for July. I currently have 3.21" of rain for the month. Will I finally be able to cash-in on one of these days? Maybe even reach average rainfall? Heat index is already 98F because of this "obnoxious" 79F dew point.
