Freeze warning for Phoenix, hard freeze warning for Tucson tomorrow morning

Posted: Updated:

PHOENIX -- A low pressure system will be moving southeast across Arizona today with even cooler weather than yesterday.

While it's going to be sunny during the day, it is going to be quite chilly, and we're looking at freezing temperatures in many desert locations overnight.

Plan on a high of 57 today, which is well below the seasonal average of 70. Overnight low tonight will be about 36 degrees. Mid-20s are possible in the outlying areas.

A bit of a warm-up is on the way so we'll be back at that seasonal average by the end of the week.

Hard freeze warning overnight around Tucson

TUCSON, Ariz. (AP) -- The National Weather Service in Tucson has issued a hard freeze warning for the overnight hours Tuesday.

Temperatures will drop into the 30s by midnight Monday with subfreezing temperatures likely by 3 a.m. and continuing through at least 9 a.m. Tuesday.

Forecasters warn the conditions could kill crops and other sensitive vegetation as well as freeze exposed pipes.

A hard freeze warning means widespread temperatures at or below 28 degrees are expected with subfreezing temperatures expected for several hours.
