DISCUSSION
IDAHO (ZONES 102 AND 103): HOT, DRY, AND BREEZY CONDITIONS CONTINUE
THROUGH FRIDAY UNDER THIS RIDGE OF HIGH PRESSURE. A FIRE WEATHER WATCH
HAS BEEN ISSUED FOR SATURDAY AFTERNOON THROUGH THE EVENING. A STRONG DRY
COLD FRONT WILL BRING WIDESPREAD WESTERLY WINDS GUSTING 25 TO 40 MPH
WITH MINIMUM RELATIVE HUMIDITIES IN THE MID TO LOW TEENS. COOLER
TEMPERATURES AND MODERATE RH RECOVERY ARRIVE ON SUNDAY BEHIND THE FRONT,
THOUGH WINDS REMAIN BREEZY.
NORTHWEST MT (ZONES 104 AND 105): HOT AND DRY CONDITIONS CONTINUE
THROUGH FRIDAY. A FIRE WEATHER WATCH HAS BEEN ISSUED FOR SATURDAY
AFTERNOON THROUGH SATURDAY EVENING. WESTERLY WIND GUSTS OF 25 TO 45 MPH
WITH ISOLATED GUSTS TO 50 MPH IN THE HIGHER ELEVATIONS ALONG THE
CONTINENTAL DIVIDE COMBINED WITH RELATIVE HUMIDITIES IN THE TEENS AND
LOW 20% RANGE WILL CREATE CRITICAL FIRE WEATHER CONDITIONS. THE DRY
COLD FRONT SATURDAY NIGHT BRINGS COOLER TEMPERATURES AND IMPROVED RH FOR
SUNDAY THOUGH BREEZY STRONG WINDS WILL PERSIST ESPECIALLY IN HIGHER
TERRAIN.
WEST CENTRAL MT (ZONES 106, 107 AND 108): HOT AND DRY CONDITIONS
PERSIST. A THREAT FOR DRY THUNDERSTORMS DEVELOPS THURSDAY AFTERNOON AND
EVENING, EXPANDING INTO THE SAPPHIRE MTNS (ZONE 108), BRINGING A RISK OF
LIGHTNING AND STRONG, GUSTY, ERRATIC OUTFLOW WINDS. A FIRE WEATHER WATCH
IS IN EFFECT FOR SATURDAY AFTERNOON THROUGH THE EVENING DUE TO
WIDESPREAD WESTERLY WIND GUSTS OF 25 TO 45 MPH AND MINIMUM RH IN THE
TEENS AHEAD OF THE DRY COLD FRONT. COOLER TEMPERATURES AND IMPROVED RH TO
FOLLOW THOUGH WINDS REMAIN GUSTY THROUGH SUNDAY.
SOUTHWEST MT (ZONES 109, 110 AND 111): ISOLATED DRY THUNDERSTORMS ARE
EXPECTED THIS AFTERNOON AND EVENING, PRIMARILY NEAR THE MT/ID BORDER
(ZONES 110 AND 111). ON THURSDAY AFTERNOON AND EVENING, CONVECTIVE
CHANCES EXPAND NORTH AND WESTWARD INTO THE SAPPHIRES (ZONE 109). MAIN
HAZARDS WILL BE DRY LIGHTNING AND STRONG ERRATIC OUTFLOW GUSTS. A FIRE
WEATHER WATCH HAS BEEN ISSUED FROM SATURDAY AFTERNOON THROUGH SUNDAY
EVENING. EXTREMELY HOT AND DRY CONDITIONS (MINIMUM RH IN THE SINGLE
DIGITS AND TEENS) COMBINED WITH WIDESPREAD STRONG WESTERLY WIND GUSTS UP
TO 45 MPH WILL CREATE CRITICAL FIRE WEATHER CONDITIONS. CRITICAL HEAT,
LOW RH, AND STRONG WINDS WILL PERSIST THROUGH SUNDAY EVENING BEFORE
COOLER AIR ARRIVES AND POST- FRONTAL WINDS SUBSIDE. AN EXCEPTION WILL BE
ON SATURDAY NIGHT, RH RECOVERS INTO THE 30-40% RANGE ABOVE VALLEY
FLOORS AND WINDS DECREASE SLIGHTLY, REMAINING GUSTY AT ELEVATION THOUGH.
