A cold gust of Arctic air reached San Diego County Wednesday bringing gusty winds and cool temperatures.
The jet stream brought an overnight influx of cool air – something we’re not used to in San Diego.
Coastal communities will see highs in the low 60s, some inland communities will see temperatures in the high 50s.
“You will want to make sure you pull out that coat,” advised NBC 7 meteorologist Jodi Kodesh. "If you're sending your kids to school - pants and a sweatshirt."
Wednesday will be overcast with gradual clearing. As the storm departs, there will be a chance of showers at the lower elevations and a possible flurry or two in the local mountains.
The National Weather Service has issued a high wind warning for San Diego’s mountains and desert areas until 8 a.m. Wednesday.
The wintry storm pushing through the western half of the country threatened crops across the state.
Citrus famers in the Central Valley checked wind machines and ran water through their fields in anticipation of temperatures at or below freezing Tuesday night, followed by even colder weather on Saturday.
However, farmers should not panic, said Bob Blakely of California Citrus Mutual, a trade association. Cold weather can be good for the crops, he said.
"Trees and fruits need some of that cold weather to harden off and prepare for late December and January," he said.
The cold air is expected to linger until next week then move east, where it will bring less-drastic temperature changes.
