Weather update: A few good changes to this morning’s forecast
Time and Day: 1000 Tuesday
The Snapshot: Rain today changing to snow tomorrow, a short dry period
tomorrow night, snow (lots) Thursday through Sunday.
The
Science: Rain will
continue through most of the day. A
little shot of cold air descending in from the north will bring a short period
of snow above 4500’ tonight. Freezing
levels will rise back up after midnight with rain continuing into the early
morning hours.
A
cold front is expected after sunrise tomorrow that will lower freezing levels to +-4000’ and change the rain to
snow before it tapers off later in the day.
Another push of moisture arrives on Thursday morning with snow likely
and then again on Friday.
Long
Range: Big snow on
the way for the weekend? A good looking
progressive winter storm is beginning to take shape for the weekend. Snow totals from Friday - Sunday 4 pm could exceed several feet.
