.DISCUSSION...Next two days will have some moisture spilling over
upper ridge but only very light snow showers expected with
accumulations of an inch or less expected today and Tuesday. Some
decent westerly flow may cause some winds upwards of 20 mph or
more today through Tuesday. A strong cold front moves through
Tuesday night and with this system expect heavier snow Tuesday
night into Wednesday with 4 to 8 inches possible. Wind flow will
shift from strong out of the southwest Tuesday night to a
northerly flow by Wednesday afternoon behind the front. Much
colder air will enter Wednesday as well.
