####018018620#### FNUS55 KTWC 092159 FWFTWC Fire Weather Planning Forecast for Southeast Arizona National Weather Service Tucson AZ 259 PM MST Mon Feb 9 2026 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 20-FOOT WIND FORECAST OF 'LIGHT WINDS' INDICATES MAINLY TERRAIN DRIVEN WINDS +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ .DISCUSSION... A low pressure system near the southern Baja Peninsula this morning will move across Sonora and Chihuahua Mexico Tuesday. The close proximity of this system will result in a northerly push of low-level moisture into the area tonight into Tuesday, resulting an increase in RHs between today and Tuesday. This will also result in a slight chance of showers, possibly with an embedded thunderstorm, from Tucson south east Tuesday. Otherwise, afternoon high temperatures will remain 6-10 degrees above normal through the middle of next week. Min RH levels will be in the 15-25 percent range for the valleys and 25-35 percent for the mountains today, increasing to 35-45 percent valleys and 45 to 65 percent in the mountains Tuesday. Another low pressure system late Thursday through Friday will bring increasing RHs, and wetting rains across Southeast Arizona with light snowfall in the highest elevations.
