ROANOKE, Va. – We hope you were able to enjoy the lower humidity over the past several days. This coming week will be the polar opposite. We’ll start with Monday, in which temperatures will be similar to Sunday but the humidity will be slightly higher.
With that in mind, we could see a few pop-up storms during the afternoon. These will happen on an isolated scale and mostly west of the Parkway. Come Tuesday, a southwest wind will translate to higher humidity levels. With dew points in the upper 60s to near 70°, that’s air you can wear.
That will lead to a heat index of 95-100° in the Roanoke Valley, Lynchburg and Southside. That’s prior to the more scattered storms that will develop after lunchtime.
Those storms are our only hope of cooling down each afternoon this week. Keep in mind that with temperatures in the 80s and 90s, along with high humidity, any storms that do develop will have the potential to become strong-to-severe. Localized flooding is a possibility too (yes, even though it’s been quite dry).
We’ll stay under this pattern’s influence throughout the rest of the week. Hot, humid air will blow in from the southwest and trigger afternoon/evening showers and thunderstorms each day.
By Saturday and Sunday, a front will be close by and could increase the amount of showers and storms we see. As that front blows through, we will likely see temperatures drop off Sunday into next week.
It’s at this point that we could be tracking a tropical system near the East Coast. A system nearing the Caribbean has a chance of developing within the next few days, so we’ll keep a close eye on its potential.
