FORECAST DISCUSSION

From chasing record highs to an approaching Winter storm.

High pressure cranks up the mercury over the next 72 hours. Temperatures peak in the mid 70s this afternoon, running 9-11° above average. Mostly sunny skies give way to mostly clear skies overnight.

Tomorrow’s forecast high of 79° is a degree shy of tying the record set in 2010. Thursday’s record high of 81° (set in 1969) will likely be reached or eclipsed.

Models continue to indicate a pattern change heading into the weekend. A cold front cranks up the winds Friday, followed by scattered showers late Friday night into early Saturday. Snow levels drop to 6,000 feet by daybreak Saturday, with rain & mountain snow tapering off late Saturday morning. Mt. Lemmon could see 1-3″ snow, while valley floors potentially pick up 0.10-0.25″ rain.

Highs this weekend struggle to reach the upper 50s to low 60s. Expect widespread freezing temperatures Saturday night.
