NATIONAL WEATHER SERVICE BOISE ID
250 PM MST FRI FEB 6 2026
SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
DRY CONDITIONS
EXPECTED OVER THE SHORT TERM WITH WINDS SLOWLY INCREASING AHEAD
OF A COLD FRONT ON SUNDAY NIGHT. A RIDGE TEMPORARILY REBUILDS
OVER THE AREA ON SATURDAY AND SUNDAY WITH MILD TEMPERATURES
CONTINUING. INCREASING WINDS ALOFT WILL ALLOW FOR MORE WARMING
ON SATURDAY AND SUNDAY WITH THE LOWEST VALLEYS APPROACHING 60F
AHEAD OF THE COLD FRONT. WINDS WILL INCREASE ON SUNDAY AND THE
AIR STAGNATION ADVISORY HAS BEEN TRIMMED TO MIDDAY.
LONG TERM...MONDAY THROUGH FRIDAY
PRECIPITATION WILL CONTINUE
INTO MONDAY OVER THE WEST-CENTRAL/BOISE MOUNTAINS, WESTERN MAGIC
VALLEY, AND SOUTHWEST ID HIGHLANDS AS THE SHORT-WAVE AN
ASSOCIATED COLD FRONT MOVES OUT OF OUR AREA. SNOW LEVELS DROP
BEHIND THIS FRONT, HOWEVER THAT IS ALSO AS THE PRECIP COMES TO
AN END. SNOW LEVELS MONDAY MORNING WILL START OUT AT 4-6KFT MSL,
BEFORE DROPPING TO 3.5-4.5 KFT MSL MONDAY AFTERNOON...AS THE
BULK OF THE PRECIPITATION IS ENDING.
BEYOND MONDAY, THE ACTIVE PATTERN WILL CONTINUE, ALTHOUGH
DETAILS BECOME A LITTLE BIT MORE MUDDY. AS ANOTHER TROUGH DIGS
DOWN TOWARDS CALIFORNIA, FLOW ALOFT WILL TRY TO SPLIT AND
DIRECT THE STORM TRACK NORTH AND SOUTH OF US. AS THIS TROUGH
DIGS DOWN HOWEVER, DETERMINISTIC GUIDANCE RESOLVES A SHORTWAVE
GRAZING OUR SOUTHEAST ZONES. AS A RESULT AM MAINTAINING A 20-30%
CHANCE OF PRECIPITATION TUESDAY AFTERNOON THROUGH WEDNESDAY
FOR THE AFOREMENTIONED ZONES. OTHERWISE, DIURNAL AND TERRAIN-
DRIVEN LIGHT SNOW SHOWERS EACH AFTERNOON OVER HIGHER TERRAIN.
THE UNSETTLED PATTERN CONTINUES TO END THE WORK-WEEK, AS
ANOTHER TROUGH IS SET TO DIG SOUTH FROM THE GULF OF ALASKA.
TEMPERATURES NEXT WEEK WILL BE MORE SEASONABLE COMPARED TO THIS
WEEK, ALTHOUGH STILL LEANING A FEW DEGREES ABOVE NORMAL.
