FIRE WEATHER PLANNING FORECAST FOR SOUTHEAST ARIZONA
NATIONAL WEATHER SERVICE TUCSON AZ
236 AM MST THU APR 9 2026
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
20-FOOT WIND FORECAST OF 'LIGHT WINDS' INDICATES MAINLY
TERRAIN DRIVEN WINDS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
DISCUSSION
AFTERNOON WINDS BECOME SOUTHWEST TO WESTERLY 10-15
MPH THROUGH FRIDAY AS A PACIFIC SYSTEM APPROACHES THE REGION.
SOUTHWEST WINDS INCREASE FURTHER THIS WEEKEND AS THE SYSTEM CROSSES
THE REGION, BECOMING 15-25 MPH WITH GUSTS TO 35 MPH. WITH THIS
SYSTEM NOW LOOKING DRIER, THE COMBINATION OF CRITICAL WINDS AND
RELATIVE HUMIDITY WILL RESULT IN THE POTENTIAL FOR FIRE WEATHER
CONCERNS AS EARLY AS SATURDAY, BUT ESPECIALLY ON SUNDAY. AS THE
FIRST PART OF THIS WEATHER SYSTEM MOVES THROUGH, ANY PRECIPITATION
THIS WEEKEND LOOKS LIMITED IN SCOPE (10 TO 20 PERCENT CHANCE
SATURDAY MAINLY GRAHAM AND GREENLEE COUNTIES). WHILE WINDS REMAIN
GUSTY EARLY NEXT WORK WEEK, COOLER TEMPERATURES AND INCREASED
MOISTURE MONDAY SHOULD HELP MITIGATE WIDESPREAD FIRE WEATHER
CONCERNS, THOUGH IT COULD STILL LINGER ALONG THE NM BORDER MONDAY.
THEREAFTER, WINDS GENERALLY 15 MPH OR LESS FOR THE MIDDLE OF NEXT
WEEK.
