AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FLAGSTAFF AZ
420 AM MST MON JUN 01 2026
SYNOPSIS
WARMING TEMPERATURES AND MAINLY LIGHT SOUTHWESTERLY
WINDS EXPECTED THIS WEEK. MOST AREAS WILL REMAIN DRY, BUT CHANCES
FOR SHOWERS AND THUNDERSTORMS INCREASE BY THE MIDDLE OF THE WEEK
OVER SOUTHERN NAVAJO AND APACHE COUNTIES.
DISCUSSION
DRY AND RELATIVELY STABLE SOUTHWESTERLY FLOW ALOFT
CONTINUES FOR MUCH OF THIS FORECAST PERIOD. HGHTS TICK JUST A BIT
ABOVE NORMAL FOR THE WORK WEEK, WITH TEMPERATURES WARMING TO ABOVE
NORMAL READINGS, LIKELY PEAKING ON WEDNESDAY.
ONE THING TO KEEP AN EYE ON, A WEAK UPPER LOW WILL INDUCE SOME
SOUTHEASTERLY FLOW IN THE TUESDAY-THURSDAY TIME FRAME. THIS MAY
IMPORT HIGHER PW VALES TO EASTERN SECTIONS OF THE CWA, ALONG WITH
SOME HIGHER DEW POINTS AS CONVECTION OVER NEW MEXICO PUSHES OUTFLOW
BOUNDARIES INTO ARIZONA. THIS MAY BE ENOUGH FOR SOME THUNDERSTORM
ACTIVITY OVER OUR FAR EASTERN ZONES IN THE SAME TIME FRAME, BUT
ESPECIALLY FOR WEDNESDAY AND THURSDAY. PROBABILITIES HAVE BEEN
DECREASING FOR THIS EVENT, BUT STILL ENOUGH TO MENTION.
ANY MOISTURE INTRUSION WILL BE SHORT-LIEVED AS ANOTHER TROUGH FORMS
FOR NEXT WEEKEND AND INTO EARLY NEXT WEEK. THIS WILL PROLONG THE DRY
AIR OVER OUR REGION, WITH A POTENTIAL FOR SOME MINOR COOLING AND
INCREASED SOUTHWESTERLY WINDS OUT AROUND DAYS 6-8.
OVERALL, NOT MUCH GOING ON, LOW IMPACT WEATHER FOR MOST OF US.
BUT, A FEW STORMS TO WATCH OVER SOUTHERN APACHE COUNTY AND PERHAPS
SOUTHERN NAVAJO COUNTY BY MID-WEEK.
