Annandale, Virginia – Bright sunshine is lighting up neighborhoods across Fairfax County this Sunday, but a significant weather change is already taking shape for the start of the workweek. Sidewalks are drying quickly, temperatures are climbing, and Monday’s rain threat is becoming the next weather story residents should watch closely.
According to the National Weather Service, Annandale will reach around 88 degrees this afternoon under mostly sunny skies. A west wind may gust above 20 mph at times, helping keep conditions comfortable despite the warming temperatures.
The more impactful weather arrives Monday. Rain chances increase sharply through the day, reaching 90 percent as showers become widespread. Thunderstorms may also develop during the afternoon, particularly after 2 p.m., as additional moisture moves into northern Virginia.
Latest weather guidance shows periods of rain continuing into Monday evening. Some downpours could briefly reduce visibility on Interstate 495, Interstate 66, Interstate 395, and the George Washington Memorial Parkway. Drivers should allow extra travel time and watch for ponding on roadways during heavier showers.
Meteorologists are now tracking a pattern shift that favors increased moisture and unsettled conditions. While widespread severe weather is not expected, isolated thunderstorms could produce gusty winds and frequent lightning. Tornado potential remains low, but residents should stay aware of changing conditions Monday afternoon.
Tuesday brings a return to drier weather with sunshine and highs in the mid-80s. Wednesday looks even more pleasant with abundant sunshine and temperatures near 85 degrees before scattered storm chances return later in the week.
Looking farther ahead, above-normal temperatures are expected to build across much of the Mid-Atlantic heading toward late week, reinforcing a summer-like pattern across northern Virginia.
