Washington, D.C. faces a developing winter storm threat with 1-6 inches of snow possible Sunday night. Weather models show increasing confidence in accumulating snowfall after a rainy Sunday morning, with the European model suggesting localized heavy bands while the American model predicts more widespread impacts.

Temperatures will remain above freezing through Saturday, with highs in the middle 50s, before a strong jetstream dip brings colder air Saturday night. The storm system developing ahead of this cold push could bring rain changing to mix and then wet snow by Sunday evening. Dynamic cooling processes may allow temperatures to drop despite daytime highs in the 40s.

Forecasters warn the exact track and intensity remain uncertain, with model consistency issues complicating predictions. The most likely impact window is Sunday afternoon into evening, potentially affecting Monday morning commutes. While not expected to match late January's severity, the timing raises concerns for school closures and delays. FOX 5 meteorologists emphasize the forecast remains fluid and will be refined as the storm's energy pieces become better analyzed by Friday night or Saturday.
