Glad the Germantown crew looks like they are in good shape. Heard from my brother west of Frederick that there is some wind damage there. Still waiting to the south to see what pops and where.
Frequency diagram of max yearly temps at DCA. 98 is the most common. 28/82 years (34%) have reached 100 degrees. However, it is streaky with a couple of 7+ year streaks without 100 degrees in the historical record.
I was being facetious, but I am surprised by the difference between my house and the airports. My max is 93.0 today. I’m not usually 5 behind IAD, so that may be the dry soil there helping out.
Euro has corrected down to 96/97. I haven’t been bullish on this heat wave in terms of chances for 100 and I remain that way. It takes a rare airmass for 100.
There has been a discussion elsewhere about the GFS long range having trouble with surface temps because it is drying out the surface too quickly and the boundary layer schemes are having a hard time as it goes further into the forecast period.
I'm skeptical that KC mixes to 600mbs and goes superadiabatic near the surface.
2010-2012 really skewed what the perception of hot is. For example, 100s are really uncommon, and are often clustered. So every year has less than a 20% chance of hitting that mark.
This is where I again complain that we got 8” of snow near the Pentagon and it immediately started melting when the sun came up. That one actually ends up on my dud list.
Now Feb 2014 had some rates in the overnight hours.
