The National Weather Service has issued a Severe Thunderstorm Watch for the District until 10 p.m. this evening, just as we return to full strength after the last round of storms. The issue tonight could be strong gusts of wind from an approaching frontal system, but the storms are fairly broken up into concentrated halos — so none of the area’s forecasters can say with much certainty whether tonight’s storms are something we need to really worry about or not. For Pepco’s sake, we’re crossing our fingers for the latter.
