There is also a Wind Chill Warning in effect from 8 p.m. to 9 a.m. Thursday for the Southern Arizona's mountains.  Gusty winds combine with cold temperatures to produce wind chill values in the -15 to -20 range. 

Wednesday, expect winds at around 10 to 20 mph across Southeast Arizona. Wind chills will also keep temperatures feeling more like the low to mid 30s than the forecasted afternoon highs of the upper 30s to low 40s for Southeast Arizona. 

In Tucson an afternoon high of 41 degrees is expected. 

Thursday morning record cold will take over Southeast Arizona. Tucson's record low for February 3rd is 21 degrees.  The forecasted low is 18 degrees.

Tips for the four Ps: People, Pets, Pipes, Plants. 

Bundle up! Dig out the hats, gloves, scarves, and heavy coats and layer up if you are going to be outside

Take pets inside.  Even the garage will be too cold for the pets in this kind of weather. Just like people, if they are not used to the cold they are very vulnerable to harm. 

Wrap pipes exposed to the outdoor air in towels and secure with duct tape. Also drip an indoor faucet overnight to keep water moving through the pipes.  Moving water freezes slower than still water. 

If plants were not covered last night that damage may already be done.  And tonight even covered plants are at risk of damage in temperatures this cold regardless of being covered.  Be prepared for damage even with precautions.
