Outstanding late July day. 78/62 currently. Looks like 81 will be the high here.

Gorgeous day. I’m ready for September.

If the O’s can keep this up, bring on October.

Back to sweating in Leesburg tomorrow.

Pleasant this morning. Low of 48 in Canaan.

Canaan is like a piece of northern Ontario here in the Mid-Atlantic.

[WxUSAF]

Down to 62!

[CAPE]

63 here. Refreshing.

[George BM]

Down to 61F at IAD.

[mappy]

[ThePhotoGuy]

65 for the low.

Maybe some EHWs?

LONG TERM /WEDNESDAY THROUGH SATURDAY/...
For the middle to latter portions of the week, an anomalous upper
ridge maintains its stranglehold over the Four Corners into the
Southern Plains. Meanwhile, troughing across eastern Canada
gradually retreats northward as a western Atlantic ridge expands
back to the Eastern Seaboard. In between the pair of ridges will be
a weakness in the flow extending from the Gulf Coast up toward the
Tennessee Valley. Overall, ensembles agree on above average 500-mb
heights extending across a vast majority of the country. This
results in a notable warming trend across the Mid-Atlantic region,
likely resulting in the hottest stretch of the year.

Multi-ensemble temperature plots show highs soaring well into the
90s during the period, particularly on Thursday and Friday. During
these days, models are in agreement in carrying high temperatures to
the upper 90s. Low-level moisture should be abundant owing to a
multi-day period of warm/moist advection. Expectations are dew
points will rise into the low 70s which allows heat indices to surge
into the 105 to 110 degree range. As this stands, heat-related
headlines would be needed both days if the forecast holds up. As is
common in these regimes, little relief is expected at night with
most seeing low temperatures in the 70s. While the region is well
into the "Dog Days of Summer", the hottest stretch of the year will
certainly require added public response. This would include limiting
outdoor exposure during the afternoon hours, staying hydrated,
wearing light-colored clothes, and finding air-conditioned indoor
spaces.

Despite all the heat and humidity in the atmosphere, daily
convective chances are quite limited. The upper ridging should
squash many of the developing updrafts. The best chance for any
relief from such storms would be across the Alleghenies.
Thunderstorm chances increase into next weekend as a cold front
slowly approaches from the north and west. A gradual reduction in
mid/upper heights is forecast to slowly bring temperatures back to
the low/mid 90s next weekend.

Noisy morning in Columbia.

Picked up 1.01” with heavy shower  this morning 

72/66

[snowfan]

3rd night in the last week I’ve been woken up by overnight storms. Lots of T&L.

Pushing 1” of rain. Early alarm clock for my flight out of BWI. Hoping storms don’t delay me.

[Herb@MAWS]

IMBY in Columbia received 1.14" from early Monday morning storm, as rain is winding down now (6:30am). 

[weatherCCB]

Rain has ended here

1.13” total

[dailylurker]

Welp. Relationship failed in Carroll County so I'm back home in the swamps of AA County sitting at 100' above sea level lol. Pouring here and very swampy. No drought here.

[BlizzardNole]

I see we are back to normal with all the rain just to my S and E -- barely a trace here.  That's why I got up and enjoyed last Friday's 3 am fluke thunderstorm -- I know that was likely the one storm of the summer for me 

[GramaxRefugee]

0.20" overnight

Sorry to hear it, but welcome back.

Best night of sleep in months and slept right through the rains. .52” and nearly 6” recorded in July.

[ThePhotoGuy]

1.69 this morning. I didn't realize storms/rain was in the forecast.

[CAPE]

Just a few drops here. Nothing measurable.

[The Dude]

.88 overnight.

The rain shadow of Frederick continues to be a powerful force.  This pattern, for whatever reason, doesn't seem to be working too well for those on the lee side of the Blue Ridge (my guess is it's due to a lack of direct hits from these shortwaves rotating through).  On the bright side, I'm loving this weather.  I'm not interested in a NW flow in July...I want that mid-Atlantic swamp filth.  The only place I want desert-like weather is in the desert.

I truly hope this cooler summer is a sign that we are going to experience some sustained blocking this winter. It would be pretty terrible, but on brand, to see us flip to some raging +NAO and hostile PNA/QBO state this winter.

End of the week heat is just in time for the end of softball season and a one-day tournament on Saturday. Weeeeeeeeeeeeeeeee

The storms fired well southeast of your area, so it's not as though some local feature caused you to miss out this morning. Just the luck of the draw!
