14:40 – Flood warnings for parts of the region, but rapid rainfall north
In the face of heavy rains, the Saturday's rainfall triggered flooding warnings for parts of the region, including Northwest DC, Montgomery County, Fairfax County, and parts of Anne Arundel, Prince George, and Calvert County.
Fortunately, the heavy rains flowing through the area move very fast and should leave the Beltway from 3 to 3:15 pm and our northern suburbs between 3:30 pm and 4:00 pm. However, it rains so badly that it can come in these rains to local flooding.
The Reagan National Airport has accumulated at least another 0.84 inches of rain since 2 pm
It is best to travel near streams and streams, some of which are still rising from the Saturday rain and are becoming faster with additional rainfall rise up.
2 pm – Heavy thunderstorm warning for southern Prince George's County
A streak of rain and storms roams into the immediate subway region from the south. Severe thunderstorm warnings were issued for the northern Charles and the southern counties of Prince George, as well as for northern Calvert and the southern Anne Arundel counties until 14:15. to 14:45
These storms can cause heavy rainfall that can cause local flooding, lightning and gusty winds. They move quickly (at 35 mph) and should leave the region north between 3 and 4 pm

FORECAST IN DETAIL
We probably will not repeat yesterday's epic record. But we're still in a wet ride, as humid air from the ocean combined with a stalled front to deliver waves of showers and embedded thunder until mid-week. Since the exact position and timing of the heaviest rain are difficult to predict, we should all pay attention to the ongoing risk of flooding in the next few days.

Today (Sunday): It's a bit foggy to start, with maybe an isolated shower in the morning. The probability of having a shower increases in the late morning, probably in the afternoon, as the winds from the southeast draw increasingly humid and unstable air from the Atlantic. We should not see the solid rain shield we saw yesterday, but rather a few separate waves of showers, each of which has the potential to deliver pockets of heavy rain and more floods. A few thunder rolls are also possible. The maximum values are near 80 in mostly cloudy skies, with increasing humidity, as the dew points rise to the 70s. Confidence: Mid High
Tonight: Scattered heavy showers and a bit of thunder are possible over the evening, perhaps they become lighter and more isolated overnight. The air gets even more unpleasant, as the dew points approach in the mid-1970s. A thick cloud cover prevents temperatures from falling sharply. Most of us settled in the 70s. The wind blows from the southeast by 10 miles per hour. Trust: Mid High

Morning (Monday): The same general pattern is expected, with mostly cloudy skies and occasional showers throughout the day. The afternoon brings the best chance of stronger showers and storms, as slightly stronger winds from the southeast (about 10 to 15 mph) continue to pump the humid and unstable air from the Atlantic. Floods continue to be a problem where ever stronger rain waves are created. The temperature trend is a bit warmer, as the heights are high in the mid-80s with very high humidity. Confidence: Medium
Tomorrow Night: Occasional rainstorms are likely to continue in the evening and possibly overnight, with the potential for some brief, intense rains. The cloud cover keeps the temperatures high again, with the lows only sinking into the middle of the 70s. Winds persist ten miles per hour from the southeast. Confidence: Medium
A Look Ahead
A front anchored across the lower Central Atlantic means more Tuesday through Wednesday with occasional rain showers and storms. Chances are that we will continue the diurnal trend with lighter showers in the morning and more rainfall in the afternoon to evening, but it's hard to pinpoint exactly how things will turn out. Heights remain in the low to mid-80s, with relentless humidity. Confidence: low-mean
