PHOENIX — Showers and thunderstorms are firing up across the high country, bringing lightning, gusty winds and flash flooding.
A Flood Watch is now in effect through Wednesday for parts of northern and western Arizona, including the Grand Canyon, the Mogollon Rim and much of Coconino, Mohave, Yavapai and Navajo counties.
Watch out for downpours that could trigger flash flooding in creeks, dry washes and near any wildfire burn scars. Low-water crossings and narrow canyons could become especially dangerous.
Even the Valley could see a few spotty showers overnight into Wednesday morning as this latest storm system moves through.
Valley highs will stay in the upper 90s on Wednesday before soaring back into the triple digits by Thursday.
As high pressure builds over the Desert Southwest, temperatures get even hotter over the weekend.
Valley highs will top 105 degrees and could even inch close to 110 degrees in some spots by Sunday and Monday.
On average, our first 110-degree day of the year happens around June 11th in Phoenix.
