DISCUSSION
MOSTLY DRY AND HOT CONDITIONS WILL CONTINUE FOR
MOST OF THE UPCOMING WEEK AS THE MONSOON MOISTURE TAP REMAINS
CUTOFF GIVEN A BROAD RIDGE DRAPED ACROSS THE SOUTHERN PLAINS.
DIURNAL CONVECTION WILL REMAIN ISOLATED (<30% CHANCE) EACH DAY
WITH MOST OF THIS STAYING CONFINED TO THE TERRAIN.
A WEAK SHORTWAVE WILL BE PASSING THROUGH MONTANA ON TUESDAY. THIS
WILL INCREASE SOUTHWESTERLY FLOW ACROSS THE REGION WITH AFTERNOON
GUSTS 20-25 MPH, AND A SLIGHT INCREASE IN POPS ACROSS FAR
NORTHEASTERN UTAH AND SOUTHWESTERN WYOMING.
THE RIDGE STRENGTHENS ACROSS THE SOUTHWEST LATER THIS WEEK WITH
HIGHS IN THE MID TO UPPER 90S ACROSS MOST VALLEY LOCATIONS ON
THURSDAY AND FRIDAY. THIS RIDGE WILL START TO ADVECT MORE MOISTURE
INTO THE AREA THROUGH THE WEEKEND WHICH WILL HELP TO INCREASE
PRECIPITATION CHANCES ACROSS MOST OF THE AREA WITH TEMPERATURES
REMAINING WARMING THAN NORMAL FOR THIS TIME OF YEAR.

THROUGH THURSDAY, WITH A LOW CHANCE OF SHOWERS AND THUNDERSTORMS
DEVELOPING ON MONDAY AND TUESDAY AFTERNOONS. CHANCE FOR WETTING
RAINS REMAINS NEAR ZERO. NEAR CRITICAL TO CRITICAL HUMIDITIES
WILL BECOME MORE WIDESPREAD ACROSS MOST VALLEYS WITH MOST HIGHER
TERRAIN SEEING MINIMUM RH IN THE 25-40% RANGE. SOUTHWESTERLY WINDS
