THE COLD FRONT IS MOSTLY THROUGH EASTERN IDAHO BY THIS POINT, BUT
THE LOW ITSELF IS STILL WORKING ITS WAY THROUGH THE AREA THIS
AFTERNOON/EVENING. RADAR SHOWS MOST OF THE MOISTURE STILL IN PARTS
OF THE SOUTH HILLS AND EASTERN HIGHLANDS THIS AFTERNOON, THOUGH
SCATTERED SHOWERS WILL CONTINUE ON AND OFF THROUGH THE EVENING,
AND WRAP AROUND MOISTURE IS JUST BEGINNING TO MOVE INTO THE
UPPER SNAKE RIVER PLAIN. WIND ADVISORY CONTINUES AS WINDS
REMAIN ELEVATED WITH THROUGH THE EVENING, SUSTAINED AT 25 TO 35
MPH WITH GUSTS TO 55 MPH. WINDS WILL DROP BELOW ADVISORY
CRITERIA LATER THIS EVENING, BUT GUSTS AROUND 20 TO 25 MPH LOOK
LIKELY TO CONTINUE OVERNIGHT.
AS MENTIONED ABOVE, WE ARE WATCHING THE WRAP AROUND MOISTURE ON
THE BACK SIDE OF THE LOW BRING A CONVERGENCE BAND OF SNOW TO
THE UPPER SNAKE RIVER PLAIN AND EASTERN HIGHLANDS THIS AFTERNOON
THROUGH EARLY FRIDAY MORNING. WE ARE STARTING TO SEE IT MOVING
INTO THE MUD LAKE AREA AND IT WILL KEEP MOVING EAST/SOUTHEAST.
CURRENTLY, CAMS ARE PAINTING A VARIETY OF SNOWFALL TOTALS IN THE
UPPER SNAKE RIVER PLAIN WITH THIS WRAP AROUND MOISTURE RANGING
FROM A DUSTING TO ALMOST 2-3" OF SNOW. THE TRUTH IS MOST LIKELY
SOMEWHERE IN THE MIDDLE. THE NBM CAME IN A BIT LIGHT WITH ABOUT
A QUARTER TO A HALF INCH FROM IDAHO FALLS TO ST. ANTHONY, SO
WENT IN AND ADJUSTED IT TO MORE OF A HALF INCH TO 1 INCH RANGE.
THE HREF IS SHOWING ABOUT A 30 TO 50 PERCENT CHANCE OF AT LEAST
AN INCH OF SNOW FOR THE FIRTH TO ST. ANTHONY CORRIDOR WITH THE
CONVERGENCE BAND AND ABOUT A 15 TO 30 PERCENT CHANCE OF 2
INCHES. AT THIS POINT, MODELS KEEP THE BAND JUST NORTH OF
POCATELLO, SO VERY LITTLE SNOW IS IN THE FORECAST FOR THE REST
OF TODAY/TONIGHT AROUND POCATELLO, BUT IF THE BAND MAKES IT
FARTHER SOUTH THAT WOULD CHANGE THINGS A BIT. KEEP IN MIND, ROAD
TEMPS AND GROUND TEMPS ARE FAIRLY WARM, SO IT WOULD NEED TO
SNOW HARD AND FAST TO OVERWHELM ROADS QUICKLY.
IN THE WINTER WEATHER ADVISORY AREAS, MOST OF THE ORGANIZED
PRECIPITATION FOR THE CENTRAL MOUNTAINS IS FINISHED, BUT SHOWERY
ACTIVITY WILL CONTINUE THROUGH THE REST OF THE AFTERNOON, SO WILL
ALLOW THE ADVISORY TO CONTINUE THERE AS PLANNED. TOTAL ADDITIONAL
SNOWFALL LOOKS TO BE AROUND 1 TO 3 INCHES AT AND BELOW PASS LEVEL
WITH AN ADDITIONAL 3 TO 6 INCHES ABOVE PASS LEVEL. IN THE EASTERN
HIGHLANDS, ADDITIONAL SNOW WILL RANGE FROM 1 TO 4 INCHES BELOW PASS
LEVEL AND 4 TO 8 INCHES NEAR PINE CREEK PASS AND EMIGRATION SUMMIT.
MOST, IF NOT ALL, OF OUR SNOW SHOULD BE WRAPPED UP BY MIDDAY FRIDAY
AS THE LOW WILL BE EXITING WYOMING AT THAT POINT. THEN, A RIDGE OF
HIGH PRESSURE BEGINS TO BUILD IN OVER THE WEST ALLOWING US TO DRY
OUT AND WARM UP AS WE HEAD INTO THE WEEKEND. HIGHS WILL GO FROM LOW
50S ON FRIDAY TO NEAR 60 ON SATURDAY, MID TO UPPER 60S SUNDAY, TO
LOW 70S ON MONDAY AND TUESDAY.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1147 AM MDT THU APR 2 2026
COMPLEX SPRING SYSTEM BRINGING A MIX OF CONDITIONS TO EAST IDAHO
THROUGH TONIGHT. WINDS REMAIN GUSTY THIS AFTERNOON INTO EARLY
EVENING WITH GUSTS 35-40KTS THROUGHOUT THE SNAKE PLAIN MAINLY
IMPACTING BYI, PIH AND IDA. GUSTS ARE EXPECTED TO REMAIN
SLIGHTLY LESS AT 25-30KTS FOR DIJ AND SUN. SHOWERS REMAIN VIABLE
FORECAST THROUGH THE REMAINDER OF THE DAYLIGHT HOURS PRIMARILY
FOR SUN AND BYI, THOUGH CONFIDENCE IS LOW AT ANY PARTICULAR
TIME, THUS KEPT VCSH PRIMARILY. SHOWERS COULD TEMPORARILY LOWER
VFR CONDITIONS TO MVFR, OTHERWISE CONTINUED VFR IS EXPECTED FOR
THESE TWO LOCATIONS. FURTHER EAST, THERE IS EXPECTATION OF A
CONVERGENCE BAND OF SNOW TO IMPACT IDA AND DIJ TONIGHT BRINGING
VIS AND CIGS TO AT LEAST MVFR AND LIKELY TOWARD IFR. BAND IS
EXPECTED TO SHIFT SOUTH TOWARD PIH. CONFIDENCE NOT QUITE HIGH
ENOUGH TO PUSH TERMINAL FORECAST TO PROB30, BUT IS ON THE CUSP.
IF BAND CAN MAKE IT THAT FAR SOUTH, CONDITIONS WILL BE SIMILAR
TO IDA WITH MVFR BORDERING ON IFR. ONCE THE PRECIPITATION ENDS
OVERNIGHT, EXPECT CONDITIONS TO SHIFT BACK TOWARD VFR.
