Extremely dry! temperatures will soar this afternoon with dry air rushing back into Arizona. At 1 PM the dew point dropped to a reading of only 2°. Dew point is a measurement of moisture in the air, and we need that number to be up at 54° or higher to have a good chance of monsoon storms. A dew point of only 2° is so low that we will be luck to see any clouds at all! Moisture will slip back into the state by Thursday. Expect hot conditions through the end of this week. - First Alert Meteorologist Aaron Pickering
