Northeasterly winds increase by late Monday morning, peaking Monday evening into Tuesday morning. Wind gusts may exceed 30 mph at times. Humidity will be very low both afternoons, in the low teens on Monday and single digits on Tuesday, and overnight humidity recovery will be poor, only in the mid 20s. The strongest winds will peak during the overnight hours, unlikely to coincide with the lowest humidity. Winds remain gusty through early Tuesday afternoon, but will begin to taper off Tuesday evening. While humidity will remain extremely low into Wednesday afternoon, still in the single digits, the lack of stronger winds by Wednesday afternoon should limit fire weather concerns. Dry conditions and above-normal temperatures will prevail through the end of the week. No precipitation is expected. .MARTIN LUTHER KING JR DAY... Sky/weather.........Mostly sunny (5-15 percent).
