More heavy rain is possible for the DC area later this week into the weekend

WPC 5-day Quantitative Precipitation Forecast

A storm system will bring the potential for very heavy rainfall later this week into the weekend ahead. Upwards of 2 inches of rain will be possible with the heaviest of it expected between Friday morning and midday Saturday.

Low pressure over the Southwest will move eastward over the next few days. As it moves eastward, it will pick up moisture from the Gulf of Mexico increasing our humidity levels and returning more clouds to the region by Thursday. A few showers will be possible by late Thursday evening into Thursday night, but the majority will fall on Friday into Saturday morning.

Model guidance thus far has been a little inconsistent as far as the placement of the heaviest rainfall, so we'll be monitoring the forecast very closely for changes. Since we are basing a lot of our forecast on the cut-off low over the southwest, if it happens to slow down or speed up as it ejects into the Plains, this will certainly bring changes to the local forecast.

Low pressure is expected to transition to the coast by Saturday morning and intensify as it moves farther into the Atlantic. Sunshine should return for Mother's Day along with breezy northwesterly winds in the wake of the low pressure area.
