FOX 10's Erica Horvatin has the details about our next possible winter storm.

PHOENIX - Monday was a quiet, partly to mostly cloudy day across Arizona. A couple of showers passed through the mountains of central AZ.

The Valley warmed to 70 degrees on Monday afternoon. The rest of the evening and night will be dry and mostly cloudy.

Overnight lows will fall into the low 50s tonight.

This Week:

Tuesday will be another mostly cloudy and mild day, with a high temperature of 70 degrees.

Two storms will impact Arizona on Wednesday and Thursday, bringing rain showers, some mountain snow and cooler temperatures.

Scattered rain will arrive on Wednesday, with the heaviest and most widespread rain falling in the southern half of AZ. Rain may turn to light snow along and north of the Mogollon Rim on Wednesday night.

The second storm will bring more scattered rain to all of AZ throughout the day Thursday. Snow is more likely in the mountain terrain of central and northern Arizona Thursday and Thursday night.

The amount of snow is still up for debate, but totals along the Rim, San Francisco Peaks and White Mountains could range from a dusting on the low end, to seven inches on the high end. Stay tuned!

Leave prepared before heading north

After recent snowfall in the high country, the Arizona Department of Transportation is reminding drivers who are heading north to never park along highways to play in the snow.

Use the highway shoulders for emergencies only. Parking on them to play in the snow is hazardous in the following ways:

Other drivers may be distracted by your vehicle.
Other drivers may pull over as well to play in the snow, compounding the problem.
Your vehicle may interfere with first responders who need to use the shoulder.
Plows can throw snow and ice far off highways.
It’s much safer to re-enter highways from on-ramps and other designated entrances

"Also, it’s not uncommon for lots of desert dwellers to take the opportunity to head north to play in the snow. So, remember to pack your patience and expect to spend extended time in your vehicle getting to and from snow play areas."

ADOT's suggestions for items to take along:

Warm clothing and blankets
A fully charged mobile phone and charger
Flashlight with extra batteries
Drinking water
Healthy snacks
First-aid kit and necessary medications
Ice scraper
Small bag of sand or kitty litter for wheel traction
Small folding shovel for snow removal
Travel tool kit and battery cables
Safety flares
Plastic bags or containers for sanitation
Road map(s)

ADOT says you and your vehicle must be prepared for driving in wintry conditions, including snow, ice and freezing temperatures.

Get plenty of rest
Plan your route in advance and notify someone about your route, destination and arrival time
Take frequent breaks from driving
Make sure your fuel tank is at least half to three-quarters full at all times
Use snow tires, chains or studded tires as recommended or required. Studded tires are permitted on Arizona highways from Oct. 1 to May 1.
Ensure your wipers, window defroster, headlights, taillights, brake lights and turn signals work
Change your motor oil to a winter grade
For electric or hybrid vehicles, be sure the battery has sufficient voltage and the connection cables are tight

Rain/flood safety tips

The American Red Cross' tips for heavy rain situations and flood safety:

Turn around don’t drown! If you must drive and you encounter a flooded roadway, turn around and go another way.
If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground.
Tune in to your local radio, NOAA radio, or news channels for the latest updates.
If your neighborhood is prone to flooding, be prepared to evacuate quickly.
Follow evacuation orders and do not attempt to return until officials say it is safe.
If power lines are down, do not step in puddles or standing water.
If power is out, use a flashlight. Do not use any open flame as alternate lighting.
