Will have slightly cooler conditions today but still warm with
highs in the 60s mountains and 70s valleys. Upper ridge builds
in Sunday with very warm conditions Sunday through Wednesday.
Highs tomorrow into the 80s low elevations and 60s and 70s
mountains. By Tuesday many low elevations will reach the lower
90s. And even some mountain areas will hit the 80s. It will be
the warmest day of spring so far. No precipiation is expected
through Tuesday. Ridge moves east Wednesday and southerly flow
aloft increases which should return some moisture and allow at
least a slight chance of showers and thunderstorms late
Wednesday into next Saturday.
