Heavy rain risk Monday in North Carolina, wet roads likely [Video]

The WXII First Warning Weather Team is tracking a weather system that will bring a chance of a few rounds of rain to our area on Monday. While localized flooding is possible from a waves of moderate to heavy rain, you may have to be under thunderstorms repeatedly to see a greater risk for flash flooding. Mondays excessive rainfall forecast is a level two or slight risk for the Blue Ridge Parkway east toward Greensboro. A marginal risk or level one excessive rainfall threat extends from Greensboro east toward Raleigh. This is not a guarantee that every neighborhood will experience drought busting rainfall, but it is a reminder to take precautions while driving during rain and storms on Monday.A broad area of low pressure will move over North Carolina Monday. In addition to support above the surface, a consistent southwesterly flow of moisture from the Gulf of Mexico will increase precipitable water values. This means that storms that do form this week have a chance to bring soaking rainfall.RAINFALL TOTALS MONDAYPockets of heavy rain may bring in excess of one inch rainfall totals especially from thunderstorms. The average rainfall from scattered showers on Monday is expected to be between two tenths of an inch of rainfall to near one half of an inch of rain. Some areas of the Piedmont Triad may receive much lighter totals depending on whether more storms develop Monday afternoon through late evening. TIMINGMONDAY MORNING COMMUTE-DRIVING HAZARDS POSSIBLERain is likely early Monday morning for the commute into the Mountains, Foothills with light to moderate showers to begin the day. Light scattered showers are also likely in the Piedmont Triad. A few forecast models hint that thunderstorms may form before the lunch hour. Hydroplaning conditions may develop on roads, and this will bring a risk for drivers. Storms bring the greatest risk of isolated flash flooding, but most areas will be dealing with wet roads and spotty ponding on roads from pockets of heavy rain.MONDAY MIDDAYSteady showers of light to moderate intensity are expected for Monday morning with lulls from the rain at times by midday.MONDAY AFTERNOON-EVENINGA few scattered afternoon thunderstorms may develop that could also intensify rainfall totals. Storm chances are dependent on how much instability develops after the morning rain and storms. Rain and storm chances should end after the evening commute. The Piedmont Triad and southern Piedmont may receive additional thunderstorms late Monday night that bring heavier rounds of lightning and downpours near High Rock Lake and Troy.RAINFALL TOTALS THIS WEEKRain is expected to be light to moderate with some occasional heavy downpours going into the weekend. Right now, the heaviest rain and highest rainfall totals are expected from Mondays scattered thunderstorms and more widespread rain possible again on Saturday. Rainfall totals between one inch and one quarter of an inch are possible on average through Saturday, August 3. Isolated amounts of two to three inches in storms are possible from thunderstorms Tuesday, Wednesday, and Friday through Saturday. Thursday may be a drier day although high temperatures climb into the 90s.WHERE TO FIND RAINFALL TOTALSOf course, check out WXII12 Radar and adjust the layers to find your desired storm information and the latest weather alerts.Many volunteer weather watchers from across the Southeast will be reporting their rainfall totals this week.
