I think July has the lowest standard deviation for monthly temps, so it doesn’t take much of an anomaly. The humidity definitely helped boost the overnight temps.
I was going to complain about my 1.10” over the past two weeks, but then I see a report from over by the DC arboretum of 0.56”. Meanwhile Silver Spring/Bethesda is at 7”. Feast or famine.
Last two runs of the HRRR seem to finally catch on that this initial line will be the main event for the metros while the later line will tap the unmodified areas to the south.
