Yesterday's 71 degree high at Reagan National was the coolest July day since July 26, 2002. With the low a mere 4 degrees less at 67, the daily average of 69 made for a whopping 11 degrees below the average for the date. That's the greatest divergence from the norm since back on April 23 when the discrepancy was13 degrees, making for a most extraordinarily cool day in a month when relentless sun makes such chill almost impossible.
The rains of yesterday are largely finished - they were significant in some areas, e.g., 1.25 inches at BWI - and just some drizzle and fog remained this morning. The low clouds are beginning to breakup amd some peeks of sunshine are appearing this afternoon. The high temperature today should be around 80, which is still about 10 degrees below normal. However, as high pressure moves to the northeast and we start to get a southwesterly flow of warmer, more humid air, look for the mercury to rise rapidly into tomorrow when the dreaded 90s return. Thunderstorms are possible both Monday and Tuesday with some drier, more pleasant days likely on Wednesday and Thursday.
Enjoy one more cooler than normal day before July comes steaming back!
