What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pocatello, ID wrote its last area forecast discussion before this winter storm warning went out at Jan 15, 7:56 PM MST, 6 hours 32 minutes earlier.
Area forecast discussion, Jan 15, 7:56 PM MST, 6 hours 32 minutes before
Area Forecast Discussion National Weather Service Pocatello ID 756 PM MST Wed Jan 15 2020 .UPDATE...Overall forecast in generally good shape. Broad band of high clouds spreading over the southern highlands this evening while region of more dense moisture beginning to spread into the central mountains. Light precipitation present over the western portions of the state has not quite made it into the central mountains as of yet, but snowfall should spread across the region during the overnight. Winds especially at higher elevations of the central mountains are quite breezy to windy with a few higher elevation gusts over 40 mph thus will leave the current Winter Weather Advisory in place. Other concerns are the very localized area of fog in the Island Park region, and temperatures in areas where the cloud cover hasn't reached yet. Have added Patchy Fog across that region, but have also lowered the overnight lows where temperatures have already approached or dropped below current forecast minimums. No further updates are anticipated this evening. DMH && .PREV DISCUSSION... /issued 131 PM MST Wed Jan 15 2020/ DISCUSSION...A pair of systems will be moving through the region. The first one arrives tonight. This will bring snow mainly to the central Idaho mountains roughly from Bellevue to Stanley. Forecast amounts came down slightly, but still looks like 2 to 6 inches with the heaviest amounts on mountain passes and ridgetop level. The second system is much more widespread and arrives Thursday night and persists into Friday. This system will bring wind to the area beginning around daybreak on Friday. Blowing and drifting will most likely be problematic with road closures once again possible, especially in those areas still recovering from the last series of storms. Forecast snow amounts came down for this next system as well as the NAM has really backed off on the amounts, probably because this system is pretty fast-moving. Still, looking at 2 to 6 corridor from Bellevue to Stanley, as well as along the eastern highlands. Probably less than 2 inches elsewhere. Even though there is some uncertainty with the snow amounts, we are very confident in wind developing and likely causing problems for eastern Idaho. Therefore we will be issuing a winter weather advisory for much of east Idaho to specifically address potential blowing and drifting snow issues. The parade of storms ends by Saturday as a ridge of high pressure develops. Could see some light snow in the central mountains and upper snake highlands on Saturday as moisture rides over the top of the ridge. But, the ridge will amplify on Sunday and persist through early next week. Valle AVIATION...After days of low CIG and occasional low VSBT due to snow, eastern Idaho will get a break until 16/06Z tonight, when the next low pressure moves in and starts to develop mid- and high level CIGs. A weak impulse will develop isolated snow showers in the central Idaho mountains, affecting KSUN, but otherwise nothing impactful happens until Thu night in terms of CIG/VSBY. However, an approaching front will mean some potential low level wind shear with strong south to west wind aloft while surface wind is north to east. It appears as though during the morning on Thu that these strong southerly wind will come into alignment as the inversion disappears. Messick && .PIH WATCHES/WARNINGS/ADVISORIES... Winter Weather Advisory until noon MST Thursday for IDZ072>074. Winter Weather Advisory from midnight Thursday night to midnight MST Friday night for IDZ052>054-058>067. &&
