The end of the heat wave is in sight but not before two more stiflingly hot days.  Look for triple digit temperatures and heat indices Saturday, with storms moving in on Sunday. 

This Afternoon: Dangerously Hot & Humid

Highs: 100-105 | Heat Index: 105-110

Tonight: Partly Cloudy, Warm, Muggy

Lows: 73-80 | Wind: W 5-10 mph

Sunday: Pt. Cloudy & Hot, PM Storms Likely

Highs: 94-98 | Precipitation: 60% Chance

It could be an historic day in Washington, but not one most of us want to live through.  Entering the tenth consecutive day of a heat wave, there's the possibility that the all-time hottest recorded temperature of 106 degrees could be equaled this afternoon. Coupled with high humidity values, the apparent temperatures could climb to near 110.  That dangerous combination has prompted the National Weather Service to issue an Excessive Heat Warning for the area from 11 a.m. until 10 p.m.  Making being outdoors even more problematic is the poor air quality.  High levels of ozone and particulate matter have resulted in a Code Red for everyone.  

Sunday will be very hot once again, but a drop in the jet stream should bring a cold front through the area by afternoon.  Showers and strong thunderstorms in the front's wake are expected to bring much more comfortable temperatures to the region with highs Monday through Saturday only in the 80s. It will be good to return to days not destined for the history books!
