Warmer & Dry Days

The rest of this week will be much warmer and dry with highs reaching the 80's Thursday through the weekend. Surface high pressure is building in from the Southeast U.S. today, and will settle over the Mid-Atlantic the rest of the week. Here's the surface map early Wednesday morning, where you can see the center of the high pressure is over eastern Tennessee:
This is accompanied by an upper-level ridge as well, which means skies will remain mostly sunny the rest of this week. High temperatures will reach the 80's Thursday through Sunday widespread in Central Virginia for the first time this Spring. The highest temperature in Richmond so far this year is 79 degrees on March 20th.

However, only minor flooding is expected from Tuesday through Wednesday afternoon in these warned counties. The James River in Richmond will barely reach flood stage today and tomorrow. Here are the forecasts for the two measurement sites near the Huguenot Bridge and near Downtown:

Showers Linger, Rivers Rise

Rain showers will linger in the Commonwealth today and tomorrow while this upper storm system slowly tracks through the Mid-Atlantic. Here is a look at the upper-levels tomorrow morning:
Rain totals were widespread in the 1"-3" range overnight into Monday morning in Central Virginia, with some locations picking up more than 3" of rain. Most of this fell in a few hours as a squall line of strong thunderstorms tracked through the Commonwealth. As a result of so much rain in the area, river levels are rising and some are expected to reach their flood stages on Tuesday. The James River in Richmond near the Huguenot Bridge should reach flood stage around 3 p.m. Tuesday and peak at 13.5 feet at 2 a.m. on Wednesday.
In addition, so much moisture at the surface is leading to fog this morning, and will likely occur again overnight and Tuesday morning where winds are lighter.
