PREV DISCUSSION /449 PM MST/
A WEAK LOW OVER SOUTHERN ARIZONA
IS BRINGING MAINLY SHALLOW CONVECTION TODAY, WITH A FEW EMBEDDED
LIGHTNING STRIKES. THE EASTERLY FLOW AROUND THIS LOW IS FAVORING
AREAS ALONG I-40 WEST OF FLAGSTAFF AND THE PRESCOTT AREA, INTO
WESTERN YAVAPAI COUNTY. THIS WILL CONTINUE TO BE THE CASE THE
REMAINDER OF THE DAY, WITH ACTIVITY DYING OFF THIS EVENING.
THE LOW STAYS IN PLACE OVERNIGHT, THEN GETS PICKED UP BY
STRENGTHENING SOUTHWESTERLY FLOW SATURDAY, EJECTING NORTH THROUGH
THE DAY. THE COLD POOL WILL GENERATE ANOTHER ROUND OF SHALLOW
CONVECTION SATURDAY, ALONG WITH BREEZIER CONDITIONS.
THE MAIN LOW MOVES INTO SOUTHERN CALIFORNIA SATURDAY NIGHT AND INTO
ARIZONA SUNDAY AND MONDAY. THIS LOW IS NOW TRACKING FARTHER SOUTH,
SO WIND AND FIRE WEATHER THREATS HAVE DIMINISHED. IT STILL WILL BE
GUSTY AND BREEZY SUNDAY, BUT THE STRONGER WINDS WILL BE FOCUSED IN
THE EASTERN PARTS OF THE STATE AND LOOK TO BE JUST BELOW WIND
ADVISORY CRITERIA.
CONVECTION WILL CONTINUE WITH THIS STRONGER LOW, AS WELL AS MORE
ORGANIZED AREAS OF PRECIPITATION ALONG THE COLD FRONT AND IN THE
NORTHEAST AND NORTHERN QUADRANTS OF THE LOW. IT WILL BE COLD ENOUGH
TO SNOW AT 7000 FEET SUNDAY NIGHT AND INTO MONDAY, WE HAVE SOME
LIGHT ACCUMULATIONS IN THE FORECAST FOR NOW.
THE MAIN LOW EJECTS MONDAY NIGHT, BUT RESIDUAL TROUGHING OVER THE
WESTERN UNITED STATES WILL KEEP A COOL AIRMASS AND DAILY SHOWERS
GOING INTO WEDNESDAY.
FINALLY, RIDGING AND WARM TEMPERATURES RETURN AT THE END OF THE WEEK.
