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.
Also could be called confirmation bias where you only remember the cases that fit your ideas. The better dynamics were always north today. Fredericksburg is missing out too, but isn’t in the DC beltway.
0.14” of pedestrian rainfall today pushing my total to 3.64” for July.
The writing on the wall for anything interesting was a couple of days ago. The line near Dulles is now kicking out an outflow boundary, so we'll see where that takes us.
Pretty cool watching the Arlington cell. The flow that would otherwise be pushing the cells to the east is balanced by the outflow to the west which keeps kicking up feeder cells.
