.DISCUSSION...
Recent observations at KDCA indicate winds have dropped off
considerably during the last couple of hours. Northwest winds may
gust to around 15 knots overnight before further weakening into
the morning hours. Skies remain mostly clear through the night
with no chances for any precipitation. The dry air mass in place
will allow temperatures to drop rather quickly over the next
several hours with a forecast low of 30 degrees. Meanwhile, the
Potomac River remains very cold with a temperature of 35 degrees,
accompanied by some areas of ice on the river.

Behind a cold front, high pressure will briefly build back into
the area on Thursday. Expect another dry day as well underneath
mostly sunny skies. Temperatures are forecast to return closer to
normal for late January with highs in the upper 40s on Thursday.
Winds are expected to shift to southerly by the late afternoon.

For the marine waters, do not expect any small craft conditions
over the next 24 hours.

For tidal purposes, the next low tide is at 2:32 AM (Thursday),
while the next high tide is at 8:26 AM (Thursday). No tidal
flooding is expected.
