Thursday turns slightly warmer; drop in humidity and heat wave to come soon after

We’ll go from the 50s Saturday morning to the 90s Sunday through next Wednesday

ROANOKE, Va. – A weak front passes through the region Thursday night, sparking very isolated showers. Outside of that, Thursday’s a slightly warmer and slightly more humid day.

High temperature forecast for Thursday, 8/17/2023

Once that front passes, however, the humidity drops off by quite a bit Friday and Saturday.

Another drop in humidity to come after a weak front Thursday night

This will lead to a very cool Saturday morning. You can probably get away with turning the A/C off at that point!

Overnight lows Friday into Saturday morning

Don’t get too comfortable with that, however. A strong area of high pressure will set up camp over the Upper Midwest starting Sunday.

High pressure leads to a heat wave late weekend into the middle of next week

The sinking air associated with this system will lead to a heat wave across the Eastern U.S. Highs will reach well into the 90s Monday and Tuesday of next week.

High temperatures reach into the 90s Sunday into next week

Storm chances will be very limited, so we’ll need to watch that in case of drought or drought-like conditions in the next one-to-two weeks.
