WASHINGTON DC METRO AREA FORECAST DISCUSSION
Early morning showers have more quickly eroded so have limited precipitation chances to patchy drizzle through 8 AM. Today`s high temperatures are likely too mild so have lowered readings to the cooler side of the guidance. For Tuesday, model guidance has a growing signal of a decaying convective complex reaching the area at some point during the day.

Cloud Base
The cloud base is the distance from the sea level to the base of the clouds. It is estimated using the current temperature and humidity to indicate an altitude where the air could be cold enough for clouds to form. There may or may not be clouds at that altitude (or at any altitude)
