And this chill it will continue: Hard freeze warning overnight in Tucson
Expect another cold night in the Tucson area, as a blast of Arctic air continues to hit Southern Arizona. A hard freeze warning will be in effect from 11 p.m. Tuesday until 9 a.m. Wednesday.
Following a stretch of temperatures well above normal, a freeze warning was issued for overnight Monday, into Tuesday morning. That cold will continue for at least another day.
Wrap your pipes, cover your plants, bring your pets inside and be kind to people who are outdoors at night.
The National Weather Service has issued a hard freeze warning for Tuesday into Wednesday. Temperatures could drop down to 22-28 degrees in the Tucson metro area, Green Valley, Vail, Marana, Oro Valley and west across the Tohono O'odham Nation to Sells.
That forecast is slightly warmer than what the Weather Service originally declared. An earlier version of the hard freeze warning said temps might fall all the way to 20 degrees.
A warming trend is expected at the end of the week, with temperatures slightly above normal for the weekend.
This past weekend, temperatures were in the upper 70s, about 10 degrees above normal. But as the sun dipped below the horizon Monday, a chill quickly fell across the Tucson valley. From a high of about 70, the temperature dropped nearly 20 degrees by an hour after sunset.
