WASHINGTON DC METRO AREA FORECAST DISCUSSION
Based on observational trends, have lowered visibilities across areas currently seeing patchy fog. Also, have continued to adjust the cloud forecast based on the westward erosion of the stratus deck. While Wednesday`s thunderstorm chances have increased, it might still be a bit overdone by the models.

In one mobile home park 200 of the 213 residents hid from the storm in the park's underground shelter. All 200 survived.
