Discussion from RNOFWFVEF


A WEATHER DISTURBANCE WILL MOVE ACROSS THE AREA TODAY AND TONIGHT. SHOWERS
AND THUNDERSTORMS ARE EXPECTED FRIDAY AND SATURDAY AS THIS WEATHER SYSTEM
TRANSITS THE AREA. ANY STORMS ARE EXPECTED TO BE HIGH BASED WITH
LITTLE IF ANY PRECIPITATION. GUSTY OUTFLOW WINDS MAY BE A CONCERN AS
WELL. ON TUESDAY ANOTHER SYSTEM WILL MOVE INTO THE AREA AND STRONG
WESTERLY WINDS MAY CREATE CRITICAL FIRE CONDITIONS.


Discussion from PHXFWFPSR


A LOW PRESSURE SYSTEM WILL BRING INCREASING CLOUDS AND COOLER
CONDITIONS TO THE REGION TONIGHT INTO SATURDAY. GIVEN THE DRIER

THUNDERSTORMS WITH GUSTY WINDS WILL BE POSSIBLE ACROSS SOUTHEAST

THE HIGHER TERRAIN AREAS NORTH AND EAST OF PHOENIX. DRIER AND WARMER
CONDITIONS ARE EXPECTED SUNDAY AS HIGH PRESSURE ALOFT RETURNS.
