A cold front will be working its way eastward into the metro area throughout the day Saturday, but its associated rainfall will arrive in the late afternoon and early evening, sparing the Bridge Run. It’ll be windy; gusts 30-35 MPH will be possible especially heading into the early afternoon, and this may contribute a bit of a headwind at times during the race. After starting in the mid-60s, temperatures should head into the low 80s in the afternoon ahead of the cold front.

A line of showers and thunderstorms will precede the cold front. It should be losing some steam with the bulk of the energy staying well north, but there is ample wind shear and should be enough instability for a few of these storms to be on the stronger side with wind damage the main concern. Some hail and even a tornado can’t be totally discounted, either, so you’ll want to make sure you have ways to get warnings tomorrow. These look to get into western parts of the Tri-County in the 3-5 PM timeframe, pressing off the coast by 6-7 PM with showers to fall for a little while afterward.

Once the front is through, cooler and drier air works its way into the area. Overall, Sunday should run about 10° cooler than Saturday with a lot more sunshine. It’ll be the pick day of the weekend for outdoor activities with comfortable warmth and low humidity.

Bridge Run: Should stay rain-free, but will be windy and a little muggy

The final call for the Bridge Run is for a rain-free but windy event. Temperatures will start in the mid-60s as things get started, but temperatures will warm quickly into the mid-70s by mid-morning. Southwesterly flow could provide a bit of a headwind at times, with sustained winds in the 20-25 MPH range with higher gusts expected. With dewpoints in the mid-60s, it’ll feel a touch on the muggy side, but it won’t be the worst it’s felt out there. Just watch for storms if your post-race activities stretch into the late afternoon. Good luck to everyone running or walking the bridge! As is tradition, I’ll probably be in bed.
