.DISCUSSION...
A warm front will move to the east this morning. Some rain and
freezing rain is occurring early this morning along and ahead of

MST in the northeast where temperatures are currently below

A cold front will quickly follow the warm front this morning. This
will bring strong west to NW winds. Wind gusts in the south will

Winds diminish tonight with a high pressure system that quickly
moves to the east Sunday morning.

A warm front moves through the area during the day on Sunday which
will bring the possibility for a mix of rain and snow in the

The next cold front Monday Night and Tuesday will bring strong
west to NW winds that may need another High Wind Warning. There
