NWS Pocatello, ID wrote its last area forecast discussion before the first event at Mar 11, 12:42 PM MST, 11 hours 18 minutes earlier.
Area Forecast Discussion National Weather Service Pocatello ID 142 PM MDT Tue Mar 11 2025 .SHORT TERM... Afternoon satellite imagery shows mostly clear skies across the region aside from some fast moving mid/high level clouds. Temperatures again are quite pleasant across the region with widespread 40s and 50s under ample sunshine. Winds are much lighter today compared to yesterday although they remain a touch breezy in parts of the Snake Plain and across the INL. This will be the last of our pleasant weather as changes will begin tomorrow afternoon but especially into Thursday. Cloud cover will be on the increase throughout the day tomorrow as begin to feel the influence of an upper level trough that will bring precip and cooler weather to the region. Rain and snow will move into the central mountains mid- afternoon and spread west to east across the area throughout the evening and into early part of the day Thursday. Snow levels initially will be very high (6500-7000ft) so the current forecast only calls for an inch or so in the Stanley basin and into the lower elevations around Sun Valley by Thursday AM. Most of the accumulations of note will be above 7kft so have opted to not issue a winter weather advisory at this time but one may be needed on the overnight shift to account for the high elevation snowfall, most of which will fall very late tomorrow evening and into Thursday AM. .LONG TERM...Thu through next Tue night. Cluster analysis has all clusters extremely close in timing with the only difference the intensity of the anomaly as either the 500mb low or the 500mb high pass over. Shortwave impulses appear to come through after the first big winter storm passes on Thu night/Fri. Weak upper level ridging may linger for Sat or Sun, but another trough arrives for Mon/Mon night. Not quite as intense as the low expected Wed/Wed Night/Thu/Thu Night. This low lingers through Tue/Tue Night. So lowest PoP should be Sat Night with slightly higher risk of precipitation on Sat and Sun. Temperatures go from near normal in the middle of the next winter storm to 8 to 12 deg F below normal for Fri, with a rebound by Sun back to around normal for highs. Then a cool down for Tue. Overnight lows stay near to slightly above normal for the period thanks to all the cloud cover. Thu is expected to have windy or very windy conditions in the Snake River plain and on the ridges. And with moderate to fast zonal flow over the region in the upper level pattern, the surface wind has abundant upper level support for breezy to windy conditions, mainly westerly flow. Thu and Mon have the windiest conditions, with Sat a close third. Messick && .AVIATION...18Z Tuesday through 18z Wednesday. Another CIG and VSBY unlimited day today and tonight, but by morning on Wed CIGs develop in the mid-levels. Precipitation should develop in the mountains around KSUN by Wed afternoon. Wind will start to turn gusty in the late morning as the next atmospheric river event moves closer. But...until then no impacts to aircraft operations from weather. Messick && .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
