Avoided the severe weather this evening, but not avoiding wet weather altogether.

Any lingering showers end, then mostly cloudy with patchy fog
Lows: upper 60s to low 70s
Wind: SW 4-8
Partly Sunny with PM Storms
Highs: Near 90
Rain: 50%
Partly Cloudy, an isolated t-storm possible
Highs: Upper 80s
Rain: 20%

We dodged severe storms this evening, but still got wet.  Rainfall added up to about 1/4" in D.C.  Our weather pattern is changing starting tomorrow and lasting well into next week, but we will still see plenty of chances for storms on and off.  The cold front that triggered today's storms will stall out over the mid-atlantic.  It is associated with a trough of low pressure that will hang out over our region.

This trough will usher in slightly cooler temps, so we say goodbye to the 90s, but we only drop into the mid to upper 80s.  Air rises in low pressure systems and with plenty of moisture still available, we will see little disturbances that move through the upper atmosphere and trigger some afternoon thunderstorms.  While we will be a little cooler and wet, the ridge in the west will feature very hot and very dry conditions. 


Record heat in the southwest will be possible through the weekend, not good for ongoing fires there.  Here, we don't really need the rain either.  Surplus for the month in D.C. is +3.32"
