.DISCUSSION...
High pressure gradually builds in from the west, providing cool and
dry weather into the start of the new work week.

Widespread frost is likely to develop early Monday morning, then
patchy frost is possible for Tuesday morning. Minimum RH values Monday
afternoon will be in the lower to mid 20s.

The chance for rain arrives late Tuesday, and then continues into
Wednesday as a cold front crosses the region. Drier weather returns
Wednesday afternoon, and persists until another system approaches late
this week.

The weather will remain seasonably cool for early spring through
much of the week, before a warming trend takes place ahead of the
late week or weekend system.
