At the end of a week of deep blue skies, the folks driving the Indy cars in the Baltimore Grand Prix races this weekend may have to contend with some rain on the track. And those in the stands will need to pack rain gear.
The forecast from the National Weather Service forecast office in Sterling, Va., say there's a 40 percent chance of showers and thunderstorms on Saturday, with a 30 percent chance through Labor Day Monday. Temperatures, at least, will be ideal, in the low-to-mid 80s. Skies, between the showers, will be partly sunny.
The issue will be a slow-moving cold front that's forecast to approach the region through the weekend. Showers and storms will crop up ahead of the front, which won't clear the area until late Monday, if the predictions from Sterling prove accurate.
The forecast is much the same for Ocean City, except that the front won't begin to affect the weather there with showers and storms until Sunday. So Saturday may be your most reliably sunny day at the beach.
One other issue in the 7-day forecast this morning is a disturbance in the far western Caribbean. For now, the National Hurricane Center is giving it only a 10 percent chance of becoming the next named tropical storm within the next 48 hours.
The thinking is that the storm, if it develops, may move to the Gulf Coast and then north along the frontal boundary into the mid-Atlantic by Tuesday. If so, we might see some serious rain by Tuesday or Wednesday next week. "Something to keep an eye on," forecasters said.
