Heavy Rain Likely in D.C. Area Monday

The D.C. area is in for yet another rainy day. The region will likely see heavy rain Monday afternoon and evening.

A flash flood watch is currently in effect for much of the region through late Monday night as the stormy weather may cause isolated flooding along creeks and stream and low-lying areas.

Additionally, some of the afternoon storms could produce thunder and lightning, but the chance of damaging winds is low.

This stormy pattern will continue throughout much of the week ahead, Storm Team4 meteorologist Tom Kierein said. However, there's only a 30 percent chance of afternoon and evening storms on the Fourth of July.

Curious why the region's been experiecing such a lasting pattern of rain?

It has to do with two opposing weather systems being stuck in place, Kierein said. First, a big area of high pressure is anchored off the East Coast. But that has allowed an area of low pressure to our west to also get stuck.

The circulations between the two are giving us a persistent southerly flow that's trapping tropical moisture all the way from the Caribbean into our region.

Those two patterns aren't showing any signs of changing until July 4, Kierein said. Each day until then, the D.C. area has the potential for tropical downpours, and Monday, the potential for flooding is especially strong.
