Southern Utah fruit growers are keeping an eye on the sky in advance of a system that will keep temperatures near critical levels, the National Weather Service said Friday.

Forecaster Wayne Brady said with breezy northerly winds, temperatures should range in the mid-20sacross much of the southern region. "This should keep minimum temperatures in the orchards of Utah's Dixie just above critical levels for apricots and possibly sweet cherries."If winds drop off just before sunrise, temperatures in the southern fruit growing area would fall to the upper teens and low 20s, Brady said.

The forecast for the southwest valleys and deserts, Wasatch Front and Cache Valley calls for a few snow flurries ending Saturday morning, becoming partly cloudy through Sunday.

Forecast highs Saturday include 40 at Salt Lake and Cedar City, 42 at Milford and Provo and 36 at Logan.

Authorities Friday cited poor weather as the cause of a rollover on the Utah-Salt Lake county line that critically injured a driver.

Jeffert L. Apple, 21, 3135 S., Second East, was in the intensive care unit at LDS Hospital with multiple injuries suffered in the 7 a.m. accident on I-15.

A warmer air mass is ahead for southern Utah through Sunday and minimum temperatures in the orchards should be in the mid-to upper 20s by Sunday night.

Looking to the start of the working week, the forecast Monday through Wednesday calls for partly cloudy skies in western Utah while fair skies will be the rule in the east. Isolated mountain showers are expected Tuesday and Wednesday in northwestern Utah. Highs through the period in the 50s to 60s; lows from the upper 20s to near 40.
