Phoenix
Light rain and isolated thunderstorms impacted the Valley early Wednesday morning, with potential for more light rain during the morning hours. The forecast predicts a return of sunshine by the afternoon, with a high temperature reaching around 91 degrees, which is warmer than the seasonal average.
An area of low pressure is currently moving onshore in Southern California, bringing moisture across Arizona, thus increasing the likelihood of showers and isolated thunderstorms. Rain is expected to cease by early afternoon, but storm chances will still exist in the state’s high country.
As the low pressure system progresses toward the Four Corners region and into Utah by tomorrow, cooler and drier air is anticipated, which will result in a drop in Valley temperatures into the mid 80s for Thursday and Friday. Morning temperatures in the Valley are projected to fall into the 50s to low 60s.
High pressure is expected to make a return by the weekend, lifting Valley temperatures back into the upper 80s. A more robust high pressure system could push temperatures back to or above 90 degrees by the middle of next week.
Additionally, a separate area of strong low pressure is moving into the Pacific Northwest, which may result in stronger southwesterly winds starting Sunday and possibly lasting into early next week. Wednesday afternoon winds in the Valley may experience gusts around 20 mph, with stronger winds projected over higher elevations.
After the passage of the low pressure system, winds are expected to decrease, allowing conditions to gradually dry out from south to north. However, light showers may still occur in far northern Arizona as the week continues.
Current Weather Overview
Currently, temperatures across Arizona are slightly above normal, with mostly sunny skies expected. Monday exhibited beautiful, warm conditions statewide, while Tuesday was predicted to be the warmest day of the week with peak temperatures reaching the low 90s.
Future Forecast
Looking ahead to Halloween, mild weather is anticipated, with average temperatures expected to be a high of 83 degrees and a low of 60. There is a 40-50% chance of above-average temperatures in Arizona for the period from October 25 to November 7. Rainfall is expected to be light overall, and no major weather systems are currently active in the region.
A Flood Watch is in effect for western, northern, central, and eastern Arizona from Thursday morning through Saturday evening due to forecasts of anticipated heavy rainfall. Rainfall totals statewide may vary significantly, with some areas possibly receiving as much as two inches or more, raising concerns about flash flooding.
Summary
Residents of Phoenix and surrounding areas should prepare for variable weather over the coming days as light rain and thunderstorms transition to cooler temperatures. The weekend is expected to bring a warmer trend, while flash flood concerns warrant attention in specific regions due to forecasted heavy rainfall.
