DISCUSSION
ISSUED AT 233 AM MDT THU APR 23 2026
TODAY THROUGH SAT NIGHT. AS THE WET LOW OF YESTERDAY EXITS, YET
ANOTHER, DRIER BUT COLDER, LOW MOVES IN FROM THE NORTH. IT WILL
PRODUCE ONLY LIGHT PRECIPITATION, BUT THE SNOW LEVELS WILL BE
LOWER AND THE VERY STRONG WEST NORTHWESTERLY WIND MEANS THAT THE
EASTERN MAGIC VALLEY WILL REACH WIND ADVISORY CONDITIONS. THE
CURRENT WINTER WEATHER ADVISORIES APPEAR ON SCHEDULE TO EXPIRE
AT THEIR CURRENT EXPIRATION TIMES, LATER THIS MORNING AND THIS
EVENING. FRI NIGHT AND SAT WILL SEE VERY LITTLE PRECIPITATION,
LIMITED TO HIGH ELEVATIONS, BUT THEN SAT NIGHT WILL SEE A RETURN
OF MOISTURE MAINLY TO THE NORTHERN HALF OF THE MOUNTAINS AND
HIGHLANDS. PRECIPITATION APPEARS TO CONTINUE LIGHT WITH INLAND
CANADA STILL BEING THE SOURCE OF THE AIR MASS.
AS EXPECTED, THIS SECOND LOW WILL BRING IN COLD AIR, PLUNGING
OVERNIGHT LOWS IN A LARGE PORTION OF THE SNAKE RIVER PLAIN AND
EASTERN MAGIC VALLEY INTO A FREEZE. HOWEVER, THE PORTIONS THAT
ARE NOT AFFECTED INCLUDES THE HIGHWAY CORRIDOR FROM IDAHO FALLS
THROUGH POCATELLO TO BURLEY. FRI NIGHT APPEARS TO BE EVEN COLDER
AND ALL BUT THE BURLEY-RICHFIELD AREA ARE AFFECTED. AFTERNOON
HIGHS BOTTOM OUT FRI AND A WARMING TREND DEVELOPS SAT, BUT
TEMPERATURES WILL ONLY WARM INTO THE 50S, MAYBE 60 IN THE
SOUTHERN MAGIC VALLEY.
THE SUPPORT FOR WEST WIND ALOFT WILL PUSH WIND IN THE EASTERN
MAGIC VALLEY TO WIND ADVISORY CONDITIONS WITH GUSTS UP TO 50 MPH
EXPECTED FOR A SHORT INTERVAL FROM MID-AFTERNOON TO EARLY
EVENING TODAY. THE WIND IS NOT EXPECTED TO REPEAT TO THIS LEVEL
ON FRI OR SAT, WITH A GRADUAL DECREASE IN THE WIND FROM DAY TO
DAY.
SUN THROUGH WED. CLUSTER ANALYSIS INDICATES A SOLID CHANCE OF
SUN AND MON REMAINING WET AND COLDER THAN NORMAL, THEN A
POSSIBLE TRANSITION TO DRIER WEATHER TUE AND WED. TUE AND WED
HAVE TEMPERATURES CLOSE TO CLIMATIC AVERAGES FOR THE TIME OF
YEAR AND BELOW AVERAGE RISK OF PRECIPITATION. ABOUT 70 PERCENT
OF THE CLUSTER SOLUTIONS FOR TUE AND WED ARE FOR A DRY PERIOD.
