NEW : Today's forecast: Partly cloudy & warm

After a hot weekend, expect slightly cooler temperatures today. Highs will still be warm and above normal though, ranging from 103-108. Partly cloudy skies and light winds can be expected. There’s a slight chance of storms along the Mogollon Rim today, and in southeast Arizona.

Throughout the week, expect a slow increase of humidity, along with partly cloudy skies, and cooling temperatures. Highs will be closer to average by midweek, and at that time, we also pick up a slight chance of storms in the Valley. The best chance of rain, of course, remains in the higher elevations around us. Rain chances for the entire state increase by the end of the week, as we tap into the remnant moisture from Hurricane Jimena.

Jimena is currently a Category 4 hurricane with sustained winds at 145 mph. Hurricane Jimena is moving NW at 8 mph, and is about 355 miles SSE of Cabo San Lucas, Mexico. The storm is expected to make landfall late Tuesday on the southern tip of the Baja California Peninsula, where hurricane warnings and watches are already in effect. Hurricane Jimena will quickly lose strength over land, and as it slowly travels along the peninsula, is expected to eventually be downgraded into a remnant low pressure system by Friday.

By midweek, we will really start to feel the effects of Hurricane Jimena. Expect increasing clouds toward the weekend, along with a rise in humidity levels. Because of the increase in moisture and cloud cover, afternoon highs are expected to drop, and only warm to around 100 by the weekend.

The final track of Hurricane Jimena, will determine our rain chances in the Valley. As of now, we’ve got about a 30% chance of seeing rain on Friday and Saturday. If Jimena veers out into the Pacific sooner, those rain chances will diminish. But, if Hurricane Jimena continues on its current path, our rain chances could increase for the weekend.
