DISCUSSION
TEMPERATURES CONTINUE TO WARM AND HUMIDITIES
CONTINUE TO DROP INTO THE WEEKEND AS HIGH PRESSURE BUILDS IN. A
BACKDOOR FRONT WILL RESULT IN BREEZY SOUTHEAST WINDS EAST OF
TUCSON AS EARLY AS FRIDAY, BUT ESPECIALLY SATURDAY. WIDESPREAD
CRITICAL FIRE WEATHER CONDITIONS ARE NOT ANTICIPATED WITH THIS
FEATURE, ALTHOUGH LOCALIZED/BRIEF NEAR CRITICAL CONDITIONS WILL BE
POSSIBLE SATURDAY ACROSS PORTIONS OF SOUTHEAST ARIZONA.
OTHERWISE, THE WARM CONDITIONS WE WILL EXPERIENCE TODAY INTO THIS
WEEKEND WILL BACK OFF THE FIRST HALF OF NEXT WEEK AS A DRY TROUGH
MOVES INTO THE REGION. THIS WILL RESULT IN STRONG AND GUSTY WINDS
RETURNING TO THE AREA MONDAY THROUGH WEDNESDAY, WITH THE
STRONGEST WINDS/POTENTIAL FOR CRITICAL FIRE WEATHER CONDITIONS
IMPACTING THE REGION TUESDAY.
