DISCUSSION
HIGH PRESSURE WILL GRADUALLY BEGIN TO SHIFT POSITION
OVER THE NEXT SEVERAL DAYS, BECOMING BETTER CENTERED ATOP THE
FOUR CORNERS REGION. IN TURN, MOISTURE WILL GRADUALLY BEGIN TO
INCREASE DAY TO DAY, WITH ISOLATED SHOWER AND THUNDERSTORM CHANCES
POSSIBLE BY FRIDAY. HEAVIER RAIN IS UNLIKELY WITH THESE
INITIALLY, BUT THESE WILL BRING POTENTIAL FOR GUSTY AND ERRATIC
OUTFLOW WINDS. BY SUNDAY ON INTO THE UPCOMING WEEK THE MOISTURE
WILL INCREASE FURTHER AS THE MONSOONAL PATTERN BECOMES MORE
FAVORABLE. THERE WILL BE DAILY SHOWER AND THUNDERSTORM CHANCES
ROUGHLY IN THE 40-50% CHANCE RANGE OR SO, AND THESE WILL HAVE
BETTER POTENTIAL FOR PERIODS OF HEAVIER RAINFALL IN ADDITION TO
SOME GUSTY AND ERRATIC OUTFLOW WINDS. ADDITIONALLY, THIS PERIOD
WILL SEE BETTER OVERNIGHT MOISTURE RECOVERY AND HIGHER DAYTIME
MINIMUM HUMIDITY VALUES.
