Does it snow in Arizona?

The kind of weather you experience in winter in Arizona largely depends on where in the state you are. The southern regions, including Tucson and Pheonix, usually enjoy sunny weather (with a slight smattering of rain here and there) with average temperatures of around 68°F, so chances are you won't even need a jacket, at least during the day. Temperatures do tend to drop to freezing levels during the night so make sure you pack a heavier coat or jacket if you're planning on participating in any nighttime activities. 

However, if you're traveling further north (think Grand Canyon National Park, Flagstaff, and Kingman), the months of December, January, and February are likely to bring cold days, frequent snowfall, and other wintry weather conditions with average temperatures of around 38°F.

Regardless of where you are, make sure to keep an eye on weather patterns throughout your stay as they can shift quickly and can sometimes be unpredictable. 

Again, what to pack for your trip to Arizona depends on which part of the state you're traveling to. Clothing items such as dresses, shorts, and t-shirts are all acceptable for the southern, drier regions, whereas jackets, coats, and warmer clothing are needed for the northern regions. It's also best to at least pack a light jacket or heavier cardigan, even if you're going to arid, desert-like areas as the temperatures can drop to freezing or below. 

You should also pack comfortable, enclosed walking shoes, a waterproof jacket in case of light showers, and a hat to protect you from the sun's rays when you're outside.
