The next couple of days have afternoon and evening scattered storms in store for us. Winds aloft will be blowing out of the northwest, allowing several disturbances to ride those winds into our area. There’s also a nearby cold front, with rain and storms developing along it as it pushes southeast through Wednesday.
Together, these features will help spark scattered showers and thunderstorms each day from Tuesday through Thursday.
As we head into the weekend, ridging will shift eastward and build over the southeast, which is clearly shown in the 500 mb anomaly composite map below (left). For our region, this transition will take us from near-normal to above-normal temperatures, so keep an eye out for possible heat advisories that may be issued this weekend.
Overall, it looks like a nice weekend ahead, with mostly sunny skies expected across the region, and of course we can’t rule out an evening isolated storm near coastal cities.
