DC Daily: Wintry Mix, River Testing, RFK Redevelopment

1) Weather: wintry mix returns for the workweek

Temperatures swung back down Monday, with snow showers possible later in the day and colder air settling in after sundown. Forecasters say a period of snow could mix with freezing rain overnight, which may leave a few slick spots—especially on bridges, ramps, and untreated side streets—before things trend warmer and wetter on Tuesday.

If you have an early commute, the main takeaway is timing: the risk for icy patches is highest late Monday night into Tuesday morning, then conditions should improve as temperatures rise.

• Build in extra travel time Tuesday morning
• Slow down on neighborhood streets and elevated roadways
• Check real-time transit alerts if you rely on buses or rail

2) Potomac & Anacostia: daily bacteria testing expands

District officials said they will increase water-quality sampling frequency at several sites on the Potomac and Anacostia, moving to daily testing for bacteria with results expected to be posted within roughly 48 hours of collection. The expanded testing comes more than a month after the region’s major sewage spill and is aimed at giving residents clearer, more regular updates as spring river activity ramps up.

Health guidance may shift as results come in, so anyone planning on rowing, fishing, or shoreline activities should watch for updates tied to water-contact advisories.

3) RFK site: local businesses invited into the redevelopment pipeline

The city is inviting small, local businesses to compete for contracts connected to the RFK Stadium site redevelopment. The mayor said the agreement includes a target share of project spending for District-based companies, with vendor opportunities beginning to roll out as demolition and early work move forward.

For many neighborhood firms, this is the practical next step: getting certified, tracking solicitations, and preparing to bid as the project advances toward new construction.
