A strong cold front will pass through the Washington Region late tonight bringing a chance of showers beginning during the predawn hours and potentially lasting through the morning rush hour before skies clear out and gusty northwest winds bring in the coldest air of the season thus far.
Highs on Monday will struggle to climb out of the lower 60s. Monday will be a day to wear your light-weight fall coat as gusty winds will keep wind chills into the 50s. As dusk approaches Monday evening the winds should begin to calm down and temperatures will drop pretty rapidly through the lower 50s into the 40s. Lows on Tuesday morning will likely dip into the upper 30s to near 40 degrees for the suburbs with DC dropping near 48 degrees.
