ISSUED AT 305 AM MDT TUE OCT 14 2025
A LOW PRESSURE SYSTEM OVER CA WILL MOVE INTO THE GREAT BASIN
TODAY, WITH CONTINUED SOUTHERLY FLOW KEEPING TEMPS MILD AND
INCREASING MOISTURE INTO SE IDAHO. ISOLATED TO SCATTERED
SHOWERS AND A FEW T-STORMS TODAY WILL INCREASE TO WIDESPREAD
SHOWERS/HIGH-ELEVATION SNOW TONIGHT INTO WEDNESDAY MORNING.
LONG TERM /WEDNESDAY THROUGH MONDAY/
ISSUED AT 106 PM MDT MON OCT 13 2025
WEDNESDAY BEGINS WITH THE CLOSED UPPER LOW IN PLACE ACROSS
CENTRAL NEVADA WITH BROAD UPPER TROUGHING IN PLACE ACROSS
EASTERN IDAHO. THIS WILL SET THE STAGE FOR A FEW UNSETTLED DAYS
ON WEDNESDAY AND THURSDAY WITH WIDESPREAD PRECIPITATION EXPECTED
THROUGHOUT THE AREA ON WEDNESDAY. TEMPERATURES WILL BE WELL
BELOW NORMAL, BY 10 TO 15 DEGREES, THROUGHOUT EASTERN IDAHO WITH
HIGHS ONLY IN THE 40S TO LOWER 50S. SNOW LEVELS WILL BE RUNNING
AROUND 7000-7500 FEET DURING THIS PERIOD SO EXPECT SOME
ACCUMULATIONS ACROSS THE HIGHER TERRAIN OF THE CENTRAL MOUNTAINS
AND EASTERN HIGHLANDS WHERE SOME WINTER WEATHER ADVISORIES MAY
BE NEEDED ABOVE THE AFOREMENTIONED ELEVATIONS FOR ACCUMULATIONS.
STAY TUNED. THURSDAY LOOKS LIKE THE COLDEST DAY WITH THE LOW
NEARLY CENTERED NEAR THE BEAR LAKE REGION WITH AREAS NEAR THE
WYOMING BORDER PERHAPS STAYING IN THE 30S TO LOWER 40S FOR
HIGHS, WITH 40S AND LOW 50S ELSEWHERE. PRECIP WILL SLOWLY TAPER
OFF FROM WEST TO EAST THROUGHOUT THE DAY AS THE LOW STARTS TO
MOVE EAST OF THE AREA OVER THE COURSE OF THE DAY.
RIDGING LOOKS TO QUICKLY BUILD OVER THE AREA ON FRIDAY AND
CONTINUING INTO THE WEEKEND WHICH SHOULD ALLOW TEMPS TO WARM UP A
FEW DEGREES EACH DAY RETURNING CLOSER TO SEASONAL NORMS BY SUNDAY.
PRECIP CHANCES LOOK LIMITED TO THE HIGHER TERRAIN DURING THIS PERIOD
ALTHOUGH ANOTHER DEEP UPPER TROUGH APPEARS POISED TO APPROACH THE
REGION ON MONDAY. AS SUCH, EXPECT CLOUDS TO BE ON THE INCREASE
DURING THE AFTERNOON HOURS SUNDAY AND INTO THE OVERNIGHT HOURS
MONDAY MORNING AS ANOTHER SYSTEM LOOKS TO BRING MUCH COOLER TEMPS
ALONG WITH RAIN/SNOW CHANCES FOR THE EARLY PART OF NEXT WEEK.
AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/
ISSUED AT 536 AM MDT TUE OCT 14 2025
LARGELY VFR CONDITIONS WILL CONTINUE TODAY AS VARYING CLOUDS AND
MOISTURE STREAM ACROSS SOUTHEAST IDAHO FROM THE SOUTH AHEAD OF
AN APPROACHING LOW. WE CONTINUE TO LARGELY HOLD WITH VCSH UNTIL
AFTER 04-09Z/10PM-3AM TONIGHT DEPENDING ON THE TERMINAL, WHEN
MOISTURE INCREASES FURTHER SUPPORTING WIDESPREAD SHOWERS AND
EMBEDDED STORMS. THIS WILL ALSO KICK OFF A THICKENING/LOWERING
TREND TO CIGS, WHICH MAY EVENTUALLY DROP BELOW MVFR WED MORNING.
