Analysis by serious weather condition professional Jeff Halverson

A persistent wedge of cold, rainy air might be gotten into and worn down by a southerly push of milder, more unsteady air, ahead of an approaching cold front. Greater up in the environment, a powerful jet stream with extreme winds and a pocket of energy will top the location from the west. These functions might set the phase for a short round of serious weather condition.

The significant unpredictability lies with how far north and west a nose of moderate air originating from the south makes it. If the cold wedge of air in location over the instant D.C. location remains strong, then the serious weather condition risk might just reach as far north as Southern Maryland. If the warmer air can make it further north, then there is a short window for serious storms around D.C.

A couple of weak twisters are possible, in addition to spread circumstances of destructive wind, with any serious storms that establish. Flash flooding, along with lightning, stay a consistent risk area-wide.

The general rule today is that our opportunities of serious weather condition typically increase from northwest to southeast throughout the area.
