PHOENIX — Major changes are coming to Arizona as a big fall storm system moves in!
Temperatures will drop nearly 20 degrees on Thursday, putting us around 20 degrees below normal for this time of year.
Phoenix will be in record territory, too. The forecast calls for a high of just 63 degrees. The record cool high temperature for the day is 62 degrees set in 1956.
Winds are also picking up as this storm system approaches.
Expect breezes across our state on Thursday with peak gusts at 25 to 30 mph.
Spotty rain showers are possible in the Phoenix area overnight into Thursday. Rainfall amounts will be light with likely less than a tenth of an inch in the Valley.
Showers and isolated thunderstorms will move across the high country before snow levels gradually drop to near 4,500 feet.
Winter Weather Advisories are in effect through Thursday evening across the Mogollon Rim, along the Kaibab Plateau and for the higher elevations across northeastern Arizona. Travel may become hazardous in these areas as the roads become icy and high winds drive blowing snow.
Flagstaff, and other areas above 6,000 feet in elevation like Williams, could pick up four to six inches of snow. Payson, Heber and Show Low will likely be in the 1 to 2 inch range.
The rain and snow will end by late Thursday night, but the cold air will stick around.
Valley highs will only reach the mid 60s on Friday, before warming back into the 70s over the weekend.
Overnight lows will fall into the 40s across the Valley by Friday morning and drop that low again Saturday morning, too.
