MN Transplant

Not home, but checked in on the pet cam and it was just one crack of thunder after another.  This is as electrical as I’ve seen in years.

That cell NE of Baltimore is just crushing a small area.

Dew point at DCA has been up to at least 78.  MD mesonet ranges from 74-78.  Disgusting.

Oh yeah, we are deep into splotchy season now

Definitely have convective initiation happening.

98.1, topping yesterday.  I think the immediate surface layer drying out helped with my temps today.

90 at 9am.  Awful 

87.4 at 8:30am.

Highs:

DCA 99

BWI 98

IAD 97 (Ties record)

I’m going to top out at 97.9.

Put this ridge over us in mid-late July and we’d be in 2011 territory.

probably 99F (with 4 straight 5-min obs of 98.6F / 37C).  We'll see!

Need the wind to kick off of Crystal City

DCA probably 98.  Reminder that 99 on the 5-min obs could be 98 or 99.  100 is 100.

I’m up to 97.5

The MD mesonet shows a good correlation between temps and sail moisture.  The Salisbury area is dry and temps continue to run a couple of degrees warmer there.  That’s why I’m still skeptical of hitting 100 this week.

93.0.  Staying inside all day.

Highs:

98 at DCA (99 was the record, way back in 2024)

97 at BWI (1 short of 2024’s record)

96 at IAD (2 short of 2024’s record)

Remember kids, always ignore the Euro surface temps in summer.

106 HI at DCA

DCA at 92, running +8 over the river wind of yesterday.

That 500 height number is close to the dreaded 600dm level.

DCA  84

IAD  86

BWI  88

Inner Harbor/Science Center is 93 lol

DCA hopped from that 84 to a 89/90 reading 13 minutes later.  Looks like we already have widespread 90s at 9:30am.

91 DCA

93 BWI

94 IAD

Before this starts, on the Global side, the ICON is the coolest and shuts the big heat down earliest, while the Euro is still insisting on topping 100.  GFS in the middle with upper 90s but pushes any relief well down the line.

The mesos have a similar spread, with the NAM Nest on the low side with mid-90s and the Canadians into the 100s.  HRRR has upper 90s to near 100 Monday.

I’m trying to determine what is the grossest part of the 18z parent NAM run, and I think it is the 108 Heat Index at 8pm on Monday.

5.08” for the week.  Almost 14” since May 1st.  Less than an inch behind 2018 for the wettest May-June combo in my 11-year record.

18z RAOB from IAD told the tale, plenty of surface CAPE and low level lapse rates, but absolutely pitiful mid level lapse rates and no shear. Had we better timing, this would've been a legit event for everyone.

You could see that it gusted out in MD while it didn’t in VA.  We had no outflow boundary.

Almost 100k w/o power in northern VA
