Pinpoint Weather: Warm Wednesday with chance for late-day storms

Weather Blog

ROANOKE, Va. (WFXR) — A cold front to the west will bring Southwest Virginia the chance for showers and storms late Wednesday and into Thursday.

Much of the region will be dry during the daytime hours Wednesday; a few isolated showers and storms west of the Blue Ridge Parkway cannot be ruled out for the afternoon, though. There will be an increase in cloud cover throughout the day with high temperatures in the 80s. A few spots in Central Virginia and Southside, such as Lynchburg and Danville, may reach the 90-degree mark.

Areas west of the Blue Ridge will have the best chance for showers and storms later in the day, more so after 3 p.m. The approaching cold front, along with leftover moisture from Nicholas, may allow showers and storms to produce downpours.

There is the potential for severe weather, as well. The Storm Prediction Center has areas along and west of the I-81 corridor under a Marginal Risk for severe weather. A few isolated strong to severe storms may develop and produce gusty winds and hail. Keep in mind, not everyone will see wet weather this Wednesday.

The cold front will sweep through Southwest and Central Virginia Thursday. There is the chance for scattered showers and storms across the region, but coverage won’t be widespread. Any shower or storm that does develop, though, may produce heavy rainfall. Thursday won’t be a complete washout, but we will notice more cloud cover overhead. Temperatures will also be on the cooler side with highs in the upper 70s and low 80s.

Lingering moisture from Nicholas will help to provide us with daily rain chances throughout the remainder of the week and into the weekend. Showers and storms will be hit-or-miss. If you’re planning on heading outside Friday or Saturday, just make sure to have a backup plan in case you need to get inside. For now, the severe weather risk is low, but thunderstorms may form. Expect high temperatures in the upper 70s and low to mid-80s for Friday and Saturday.

An area of high pressure will begin to build into the region during the weekend. By Sunday, rain chances will be a bit lower. However, there will still be a chance for a few isolated showers and storms during the afternoon. High temperatures will be in the upper 70s and low to mid-80s.

Tracking the Tropics

Nicholas is a tropical depression but it still poses a risk for significant flooding in parts of Louisiana. The system will linger over Louisiana for the next few days as it continues to weaken.

The National Hurricane Center (NHC) is watching two other systems with a high chance for tropical development in the Atlantic Basin.

The first is east of the Bahamas. This system has a 70-percent chance of developing into a tropical cyclone in the next five days. The cold front that will push through our area Thursday is expected to interact with this system and guide it out to sea. However, those along the coastlines of Virginia and the Carolinas could see some showers and storms as this storm passes by.

The second system is off the coast of Africa. It will move out into the middle of the Atlantic Ocean over the next few days. It will be a while before this storm impacts any landmasses. NHC says there is a 90-percent chance for this system to develop into a tropical cyclone during the next five days. It has an 80-percent chance to develop into a tropical cyclone in the next two days.
