Until tonight : Continue to hydrate yourself conscientiously and look for air conditioning in the evening, as temperatures do not cool quickly. We can only go down to the upper 70s to the lower 80s for many places. Skies are mostly partly cloudy and southerly breezes remain at or below 10 mph. The chance of showers and thunderstorms is at best 10%.

Tomorrow (Monday): The morning sky is a little clearer than the afternoon sky. High temperatures can reach the mid-90s before the chance of rain increases by mid-afternoon. Dew points near miserable levels in the mid-70s again create heat index values near the mid-100s.
As a cold front approaches, damaging winds and downpours are possible in all thunderstorms, and they can continue until dawn. Low to mid 70s feel a little better for low temperatures as dew points slowly drop back into the 60s.
High probability of severe storms tomorrow
Expect the severe storm threat tomorrow. We have a 2 in 5 chance of seeing severe storms, as indicated by the yellow shading. If a storm were to become severe, its main threat would be damaging gusts of wind. Around DC, that means winds of 58 mph or more from a thunderstorm.
A secondary threat may come from torrential rains. In this second graph, we have a slight chance – at least 5% – of seeing excessive precipitation. This means that within 25 miles of any point in the green shade, flash flood criteria could be met. Let’s keep up to date with the weather until tomorrow afternoon and overnight as well. We will keep you informed.
