moderate risk situation where a warning is a high-risk situation so a heat advisory foromorrow and likely an excessive heat warning in effect for saturday and sunday. ut., i mean, check it no matter what way you slit it, you need to take it easy. 8:00 a.m.mo toow, already feels like we're in the 80. we move towards lunchtime. we have triple-digit heat indices across the area so it's feeling like 103 or 105 in washington, annapolis, justimore, gaithersburg and about everywhere on the map. it has a triple-digit heat index. tomorrow at lunchtime it only gets worse as we head towards 4:00 p.m., so we actually might see our heat advisory upgraded to an excessive heat warning in parts of the area tomorrow. based on these numbers here, feeling about 107 degrees in washington tomorrow at 4:00 p.m. and then as we move towards the evening hours it's still dangerously hot out there. 7:00 p.m. it's still feeling 06 about 1n leesburg as well as down in fredericksburg.
