TUCSON - A strong storm system will bring the first significant valley rain, mountain snow and gusty winds of the year.
Showers will spread into southern Arizona throughout the day and will continue off and on before finally tapering off from west to east Sunday morning. Valley locations are expected to receive between 0.25"-0.75" with locally higher amounts over 1.00" possible. A rumble of thunder may also be heard this afternoon.
This is not a particularly cold system with snow levels starting out as high as 8,500ft on Saturday before falling to as low as 6,500ft early Sunday morning.
A Winter Weather Advisory is in effect for the Catalina and Rincon Mountains above 7,000ft from 1pm Saturday until 10am Sunday. 6-12" of snow may fall during this time period leading to hazardous winter travel.
A Winter Storm Warning is in effect for the White, Pinaleno and Galiuro Mountains above 7,000ft from 1pm Saturday until 10am Sunday. 10-20" may fall making for difficult travel and reduced visibility.
Gusty winds will also accompany this system today with gusts in Tucson up to 30mph. Stronger winds are expected across Cochise County where a Wind Advisory is in effect from 10am to 6pm today. Gusts in Cochise County may reach up to 45mph in some areas especially the mountains. Localized blowing dust and a strong southwest crosswind will make for difficult travel.
Daytime highs will remain slightly below average in the mid 60s both today and Sunday. As we dry out a gradual warming trend will take over as we head into this upcoming work week.
