February on the Arizona Trail brings strong contrasts. Southern lowlands often see sunny, dry stretches broken by brief showers, with daytime temperatures commonly 15 to 25°C and nights near 0 to 9°C. Higher ranges and central highlands swing between bright days and winter storms that drop rain and snow, with daytime 6 to 20°C and frequent subfreezing nights. Farther north on the Mogollon Rim and Kaibab Plateau it is distinctly wintry: daytime 0 to 10°C, nights -5 to -14°C, and recurring snow events that range from light dustings to 10 to 30 mm or more. Cloud cover varies from clear to overcast across the month, with quick transitions.
Near the Mexico border into the first sky-island canyons, days often range from 6 to 23°C with nights -4 to 9°C. Skies alternate between clear and overcast with occasional light drizzle, and brief winter storms deliver heavy snowfall around 12 to 15 mm. Precipitation is otherwise sparse.
Across the rolling foothills east of Tucson, clear spells dominate but short rain pulses near 7 mm appear, and an isolated light snowfall occurs. Highs reach 11 to 27°C with nights -4 to 12°C. Cloud cover fluctuates from overcast to sunny.
Climbing into higher slopes, winter systems bring snow totals near 8 to 12 mm and rain around 5 mm. Temperatures swing from 1 to 25°C by day with nights -9 to 11°C. Overcast periods are common between bright breaks.
Through the middle desert basins and uplands, conditions vary from sunny to stormy. Rain events peak near 26 mm, with isolated light snow around 3 mm. Daytime temperatures sit from 12 to 30°C and nights -4 to 14°C.
Approaching the Superstitions and Tonto country, repeated fronts mix rain and snow. Rain commonly reaches 6 to 16 mm, while snowfall around 13 mm lands on higher ground. Highs span 7 to 27°C with lows -1 to 12°C.
Across the Mazatzal high country, February turns wintry. Heavy snowfall reaches about 24 to 48 mm in places, and rain can spike to roughly 31 mm. Highs range -2 to 22°C and nights plunge to -16 to 5°C.
Northward toward the Mogollon Rim, lower river corridors stay mostly dry and mild, but the Rim accumulates frequent snow. Heavy snowfall climbs to about 33 mm on some days. Temperatures vary from 0 to 24°C by day with lows -14 to 7°C.
On Anderson Mesa and the open Coconino Plateau, storms arrive in succession. Snowfall varies from light to heavy, roughly 2 to 46 mm, with cold, clear interludes. Highs run 0 to 18°C and lows -10 to 1°C.
Near the Grand Canyon’s South Rim, snow recurs with individual events near 2 to 11 mm. Daytime temperatures are -1 to 14°C with nights -11 to -1°C. Skies shift rapidly between overcast and clear.
Crossing the North Rim and Kaibab highlands, storm trains bring rain bursts and repeated heavy snow around 4 to 19 mm. Highs sit between -5 to 14°C and lows -11 to -2°C. Cloudy stretches dominate.
Beyond the high plateau to the state line, conditions oscillate between sun, rain, and snow. Heavy snowfall is near 11 mm and a notable rain pulse is about 14 mm. Highs range 4 to 24°C with lows -7 to 4°C.
