Hot Weather to Start the Week, Storms to End It Featured

Well, we hope there will be storms, anyway.

Big Idea

  • Look for warm and dry through Thursday
  • A chance for showers from Friday - Sunday
  • We might get some remnants from Hurricane Kay
  •


Only a minimal chance for showers at the beginning of the week


Forecast Summary:

Mostly sunny and hot the next few days. Light wind, except for south to southwesterly breezes in the afternoons with only a slight possibility for isolated high-based showers or thunderstorms. Highs in the mid 90s, lows in the lower 60s. Increasing clouds Thursday, with mostly cloudy skies, cooler temperatures, and a chance for showers or thunderstorms each day Friday – Sunday.

Forecast Discussion:

Strong high pressure aloft, centered over Utah, has led to so much subsidence warming over northern Arizona that the atmosphere has dried out considerably these past few days. Despite strong easterly flow across our area off the Mogollon Rim and good low-level wind shear, the low-level moisture content is pretty marginal. The probability for showers or thunderstorms to develop these next few days will be very minimal. High temperatures will be well above normal through about Thursday. 

For the weekend and early next week, a complicated weather pattern sets up. Tropical Storm Kay off the western coast of Mexico will strengthen into a hurricane and propagate generally northwestward. Most forecast models indicate that Kay will stay on the western side of the Baja of California, directed offshore by easterly winds around the mid-level high. The high will eventually weaken as the hurricane approaches and shift to the south and east as weak troughing develops along the West Coast. This pattern will cause cloudiness shearing off from Kay to move across Arizona this weekend, cutting off some of our solar heating and keeping the air more stable. But there is also some indication that Kay will cause additional low-level moisture to surge across our area. If we can get enough low-level moisture up here along with enough solar heating and shearing in the winds, we could see considerable shower and thunderstorm activity this coming weekend and early next week. If not, at least the high pressure will weaken and the cloudiness from Kay will bring welcome cooling of about 10 degrees by Friday – Saturday and maybe some light rain over the weekend and early next week. The remnants of Kay may eventually swing across Arizona by next Tuesday – Wednesday for a continuing chance of light showers.

Curtis N. James, Ph. D. Is a Professor of Meteorology at Embry-Riddle Aeronautical University in the Department of Applied Aviation Sciences.

He has taught courses in beginning meteorology, aviation weather, thunderstorms, satellite and radar imagery interpretation, atmospheric physics, mountain meteorology, tropical meteorology and weather forecasting techniques for over 16 years. He participates in ERAU’s Study Abroad program, offering alternating summer programs each year in Switzerland and Brazil.

He earned a Ph.D. in Atmospheric Sciences from the University of Washington (2004) and participated in the Mesoscale Alpine Programme (MAP; 1999), an international field research project in the European Alps. His research specialties include radar, mesoscale, and mountain meteorology. He earned his B.S. in Atmospheric Science from the University of Arizona (1995), during which time he gained two years of operational experience as a student intern with the National Weather Service Forecast Office in Tucson, Arizona (1993-1995).

Dr. James is a native of Arizona where he currently resides with his wife and five children. He is active in his community, having served on the Prescott SciTechFest Advisory Committee and as a Board Member for the Children's Museum Alliance, Inc.
