The local office's own words before the first event, 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 the first event at Feb 28, 1:53 PM MST, 11 hours 7 minutes earlier.
Area Forecast Discussion National Weather Service Pocatello ID 153 PM MST Tue Feb 28 2017 .SHORT TERM...Tonight through Friday. The latest satellite and radar imagery was showing a weak storm system shearing SE into Wyoming early this afternoon with ongoing light snowfall trailing across the region. Winds recently began to ramp up and are still expected to produce advisory level wind speeds across the Upper and Lower Snake River Plain through early evening. Numerical models remain fairly consistent with the idea that a ridge of high pressure will slowly expand along the NW coast as additional disturbances dig SE into the NRN Rockies/Upper-Midwest Wednesday through Friday resulting in periods of light snowfall over the NW facing aspects of the CNTL and NE mountains. Temperatures will also gradually rise through the period with a slow resumption of snow melt anticipated within the ERN Magic Valley and Snake River Plain. Huston .LONG TERM...Friday night through Tuesday. A cold front will move through the region Sunday. Expect mild conditions Saturday ahead of the front with most precipitation in the mountains. Expect more widespread precipitation Sunday with the frontal passage with snow levels likely reaching valley floors late in the day. The timing of this system will likely still vary the next couple of days so no real snow amount forecasts yet. European has a much quicker warmup Tuesday and is much drier than GFS solution which keeps it much cooler and wetter Tuesday. GK && .AVIATION...Have had snow showers and periods of MVFR and IFR today at the sites. Think it should gradually improve after sunset with the main threat stratus overnight. Went with some MVFR to IFR ceilings at IDA and PIH by early morning. 15 to 25 knot sustained winds expected at BYI, PIH, and IDA through sunset as well. GK && .HYDROLOGY...Cooler temperatures have helped to mitigate snow melt issues. The next warm up comes late this week peaking on Saturday with snow melt follow-through expected into Sunday. Huston && .PIH WATCHES/WARNINGS/ADVISORIES... Wind Advisory continues until 7 PM MST this evening for IDZ020-021. Winter Weather Advisory until 8 PM MST this evening for IDZ019-023. &&
