Detailed Forecast Discussion |
The difference in pressure between a strong ridge building over the Great Plains and a low over Baja has resulted in gusty easterly surface winds over much of southern Arizona today; similar winds are expected until about late morning on Tuesday. Since winds are rather gusty, local ozone levels should be relatively low thru Tuesday despite the easterly component. An evolving southeast to southerly low-level wind flow is predicted to transport a modest amount of monsoon moisture northward over the local forecast area and points west by Tuesday. This will result in a slight chance for Valley shower and thunderstorms thru Wednesday and an increased risk of blowing dust via gusty outflow boundary winds. Since no local significant rains have fallen since August 28, any outflow winds that exceed 30 mph or so will be capable of producing areas of dense blowing dust from areas of disturbed soil. -Reith |
