WASHINGTON DC METRO AREA FORECAST DISCUSSION
Have continued to trend temperatures down today given the semi- permanent low stratus deck blanketing much of the region. Otherwise, have lowered dew points on Monday closer to the model consensus. The signal for locally heavier precipitation remains on Monday for those in central Virginia eastward into southern Maryland. Any flood risk would be tied to the heaviest showers or in spots with saturated grounds from recent bouts of rain.
