DISCUSSION
STRONG WINDS AND DRY CONDITIONS LEADING TO POTENTIAL CRITICAL
FIRE WEATHER...
TODAY: A BROAD RIDGE IS STRETCHING ACROSS THE PACIFIC NORTHWEST WITH
THE APEX CENTERED OVER WESTERN MT. IT WILL CONTINUE TO PROMOTE THE
DRY, WARM PATTERN THAT HAS BEEN IN THE INLAND NORTHWEST SINCE
WEDNESDAY. 850MB MAX TEMPERATURES RANGE FROM 22-24C ON FRIDAY. IT
WILL KEEP TEMPERATURES IN THE UPPER 80 TO 90S FOR MOST. LEWISTON HAS
AROUND A 50% PROBABILITY OF REACHING TRIPLE DIGITS. AREAS BEING
IMPACTED BY WILDFIRE SMOKE COULD HAVE A FEW DEGREES SHAVED OFF THE
FORECAST HIGH. HEATRISK REMAINS MINOR TO MODERATE ACROSS THE REGION.
AFTERNOON WINDS WILL INCREASE WITH WEAK AFTERNOON THERMAL LOWS WILL
BRING BRIEF INCREASES TO WINDS WITH GUSTS REACHING INTO THE TEENS.
OVERNIGHT LOWS WILL BE IN THE 60S.
SATURDAY: IT CONTINUES TO BE MAIN FOCUS FOR THE UPCOMING WEEKEND.
THERE IS HIGH CONFIDENCE FOR THE WINDS ON SATURDAY. ENSEMBLES
CONTINUE TO SWING A STRONG +120KT UPPER LEVEL JET ACROSS WA AS A LOW
SWINGS INTO THE LOWER BC. ANY CHANCE OF PRECIP ACROSS THE REGION
WILL LIMITED TO THE CASCADE CREST. THE LOW WILL PUSH A STRONG DRY
COLD FRONT THROUGH THE INLAND NORTHWEST WITH 850MB-500MB WINDS
RANGING FROM 30-60KTS. THE WINDS WILL MIX DOWN TO THE SURFACE AS THE
FRONT PASSES. WESTERLY WINDS WILL BEGIN TO INCREASE IN THE LATE
MORNING AND CONTINUE INTO THE EVENING. TIMING FOR THE STRONGEST
WINDS WILL BE IN THE AFTERNOON TO EARLY EVENING HOURS. ENSEMBLES
HAVE BEEN VERY CONSISTENT WITH SPEEDS AND TIMING. FOR SPEEDS,
SUSTAINED WINDS WILL BE IN THE 20 TO LOW 30 MPH RANGE. WEAKER WINDS
IN THE TEENS WILL BE OVER THE LOWER IDAHO PANHANDLE. FOR GUSTS, A
RANGE OF 30 TO LOW 40S FOR MOST. THE LOWER IDAHO PANHANDLE WILL HAVE
GUSTS INTO THE 20S. OUTSIDE OF THE LOWER IDAHO PANHANDLE,
PROBABILITY OF WIND GUSTS GREATER THAN 35 MPH IS AT LEAST 60
PERCENT. SOUTHEAST WASHINGTON, LEWISTON, AND WESTERN COLUMBIA BASIN
INCLUDING WATERVILLE PLATEAU DOWN TO WENATCHEE HAS 20-40 PERCENT
PROBABILITY FOR GREATER THAN 50 MPH GUSTS. OUTSIDE OF FIRE WEATHER
CONCERNS, IMPACTS INCLUDE BLOWING DUST AND MINOR TREE AND PROPERTY
DAMAGE. IT WILL BE SOMETHING TO KEEP AN EYE ON FOR THE NEXT MODEL
RUNS. HIGHS FOR THE DAY WILL BE IN THE SLIGHTLY COOLER WITH A RANGE
OF UPPER 70S TO LOW 90S. OVERNIGHT LOWS WILL BE IN THE 40S TO 50S.
SUNDAY: WHILE TEMPERATURES WILL BE A LOT COOLER, WINDS WILL CONTINUE
TO BE BREEZY. THE REGION WILL SEE WINDS SUSTAINED IN THE TEENS WITH
GUSTS INTO THE 20S CONTINUING TO IMPACT ONGOING AND NEW FIRES IN THE
AREA. WINDS WILL SHIFT TO OUT OF THE NORTH AND FUNNEL DOWN THE
OKANOGAN ACROSS THE WATERVILLE PLATEAU BRINGING LOCALLY HIGHER
SPEEDS WITH GUSTS INTO THE 30S. HIGHS WILL BE IN THE 70S TO MID 80S.
OVERNIGHT LOWS WILL BE IN THE 40S TO MID 50S.
MONDAY THROUGH WEDNESDAY: A FLAT RIDGE WILL FILL IN BEHINDS THE
EXITING LOW. TEMPERATURES WILL REBOUND BACK INTO THE 80S TO LOW 90S.
WINDS WILL CONTINUE THE DIURNAL TREND OF BREEZY AFTERNOONS AND CALM
OVERNIGHTS. THE WARM, DRY PATTERN WILL CONTINUE WITH NO CHANCES OF
BENEFICIAL PRECIP FOR THE START OF AUGUST. OVERNIGHT LOWS WILL BE IN
THE 50S. /JDC
