DISCUSSION
IDAHO (ZONES 102 AND 103): HIGH PRESSURE RETURNS TODAY WITH WARMING
TEMPERATURES AND GENERALLY LIGHT, TERRAIN-DRIVEN WINDS. THERMAL BELTS
WILL REDEVELOP AND LIMIT OVERNIGHT RELATIVE HUMIDITY RECOVERIES ALONG
MID- SLOPES AND RIDGES, WHILE VALLEY BOTTOMS EXPERIENCE MODERATE TO GOOD
RECOVERY. MONSOONAL MOISTURE RETURNS TUESDAY INTO WEDNESDAY, GRADUALLY INCREASING
AFTERNOON SHOWER AND THUNDERSTORM CHANCES WITH LIGHTNING AND GUSTY
OUTFLOW WINDS.
NORTHWEST MT (ZONES 104 AND 105): HIGH PRESSURE REBUILDS TODAY, BRINGING
WARM AND DRY CONDITIONS WITH GENERALLY LIGHT DIURNAL AND TERRAIN-DRIVEN WINDS.
THERMAL BELTS WILL BEGIN TO RE-ESTABLISH, LEADING TO POOR OVERNIGHT
RELATIVE HUMIDITY RECOVERIES ON MID-SLOPES AND RIDGES. MONSOONAL
MOISTURE SPREADS INTO THE REGION AS EARLY AS WEDNESDAY, BRINGING A MIX
OF DRY AND WET THUNDERSTORMS WITH LIGHTNING AND OUTFLOW WIND CONCERNS.
WEST CENTRAL MT (ZONES 106, 107 AND 108): HIGH PRESSURE BRINGS WARM AND
DRY CONDITIONS TODAY WITH GENERALLY LIGHT, TERRAIN-DRIVEN WINDS.
OVERNIGHT RELATIVE HUMIDITY RECOVERIES WILL BECOME INCREASINGLY POOR
ALONG MID- SLOPES AND RIDGES DUE TO THERMAL BELTS RESTRENGTHENING.
THUNDERSTORM CHANCES EXPAND NORTHWARD TOWARD THE I-90 CORRIDOR TUESDAY
AFTERNOON, INCREASING IN COVERAGE FOR WEDNESDAY WITH A MIX OF DRY AND
WET STORMS RENEWING LIGHTNING AND GUSTY OUTFLOW WIND POTENTIAL.
SOUTHWEST MT (ZONES 109, 110 AND 111): HIGH PRESSURE REBUILDS TODAY WITH
WARMING TEMPERATURES AND GENERALLY LIGHT DIURNAL AND TERRAIN-DRIVEN WINDS.
THERMAL BELTS WILL RESTRENGTHEN AND HOLD BACK OVERNIGHT RELATIVE
HUMIDITY RECOVERIES ACROSS MID-SLOPES AND RIDGES. MONSOONAL MOISTURE
BRINGS RETURNING SHOWER AND THUNDERSTORM CHANCES THIS AFTERNOON ALONG
THE MONTANA-IDAHO DIVIDE, EXPANDING NORTHWARD FOR TUESDAY, AND EVEN FURTHER
WEDNESDAY RENEWING LIGHTNING AND ERRATIC WIND GUST THREATS.
