* Flash Flood watch through 10 p.m. except western suburbs *
Although Baltimore, counties near the Chesapeake Bay, and parts of Frederick county got socked with heavy rain today, amounts tended to be more moderate elsewhere. Along and east of I-95, areas of heavy rain continue this evening but taper off to the west. By late tonight, everyone dries out. Over the weekend, we can’t totally shake the shower chances, but they’re far less numerous than today.
Through Tonight: Heavy rain is likely this evening along and east of I-95, but tapering off from south to north between 6 and 9 p.m. West of I-95, light to moderate rain tapers from south to north between about 5:30 and 7 p.m. After the rain ends, we may have some breaks in the cloud cover, with lows in the low-to-mid 60s.
Weekend forecast: Despite mostly cloudy skies both days, there may be some intervals of sunshine, especially Saturday. There’s a chance of showers both days, but only about a 30% chance Saturday and 40-50% chance Sunday - with the most likely timing being the late afternoon or early evening. Neither day looks like a washout, and outdoor activities will be possible despite the chance of an interruption or two. High temperatures tend to be in the mid-to-upper 70s. Overnight lows are in the low-to-mid 60s.
