FIRE WEATHER PLANNING FORECAST FOR SOUTHEAST ARIZONA
NATIONAL WEATHER SERVICE TUCSON AZ
1230 AM MST THU APR 23 2026
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
20-FOOT WIND FORECAST OF 'LIGHT WINDS' INDICATES MAINLY
TERRAIN DRIVEN WINDS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
DISCUSSION
WARM AND DRY ACROSS SOUTHEAST ARIZONA WITH
PERIODS OF HIGH CLOUDS THROUGH SATURDAY. BREEZY CONDITIONS EACH
AFTERNOON WILL RESULT IN ELEVATED FIRE CONDITIONS EAST OF
TUCSON INTO THE WEEKEND...WITH AREAS NEAR THE AZ/NM STATE LINE
EXPERIENCING BRIEF CRITICAL FIRE CONDITIONS THIS AFTERNOON.
MINIMUM RHS WILL GENERALLY BE IN THE 10-20 PERCENT RANGE THROUGH
SATURDAY, THEN INCREASE TO 15-25 PERCENT IN THE VALLEYS AND
25-35 PERCENT IN MOUNTAINS SUNDAY WITH THE WEATHER DISTURBANCE
MOVING INTO THE AREA.
A WEAK WEATHER DISTURBANCE MOVING INTO SOUTHEAST ARIZONA WILL
BRING STRONG AND GUSTY WESTERLY WINDS CAPABLE OF PRODUCING AREAS
OF BLOWING DUST BOTH SATURDAY AND SUNDAY, ALONG WITH A SLIM
CHANCE OF MAINLY DRY STORMS NORTH OF TUCSON SATURDAY NIGHT INTO
SUNDAY. SATURDAY 20-FOOT WINDS WILL BE 20-25 MPH WITH GUSTS
40-45 MPH LEADING TO THE POSSIBILITY THAT SOME AREAS FROM
CENTRAL PIMA COUNTY EASTWARD COULD SEE CRITICAL FIRE WEATHER
CONDITIONS. WINDS WILL STILL BE STRONG SUNDAY EAST OF TUCSON,
BUT WITH RH VALUES INCREASING...THE THREAT FOR CRITICAL FIRE
WEATHER CONDITIONS IS GREATLY REDUCED.
