Area forecast discussion National Weather Service Pocatello Idaho 420 PM MST Wednesday Nov 25 2015 Update...adjusted winds tongiht for very strong northerly surface pressure gradient resulting in winds gusting around 50 to 55 miles per hour in a few locations in the Arco desert and Interstate 15 near DuBois. Gradient looks strong through or a bit later than midnight. Receiver station && Previous discussion... /issued 142 PM MST Wednesday Nov 25 2015/ Short term...tonight through Friday. Main center of the low is still over central Nevada which seems to be the timing of the forecast off. Snow has been ongoing across the base of the central mountains as expected and should continue into the evening before diminishing overnight. Snow showers have been developing over the southern Highlands...more or less as expected but sun actually broke out across the eastern Highlands and snow has not been widespread across the Magic Valley. Thinking the slow progression of the low is largely to blame for both of these factors. However the overall forecast is still reasonably OK. The low continues to track east tonight. Models continue to show snow developing across Utah and east Idaho which will work its way into southern and eastern Idaho throughout the night. Snow intensity will weaken during the morning hours on Thanksgiving and begin to diminish during the afternoon and evening. Additional snow totals starting 00z this evening should amount to 2 to 3 inches from Pocatello to Rexburg...including the Driggs area. An additional 2 to 3 inches is likely from Carey to Arco. The Magic Valley including I 84 to the Utah border should see 2 to 5 inches. Meanwhile 2 to 4 inches is likely across the southeast Highlands including Soda Springs and Montpelier areas. Winds will continue to produce blowing and drifting conditions...mainly across the snake plain from near the i84/86 interchange northward throughout the night. Snowfall will come to an end Thanksgiving night with cold but dry weather likely for Friday. Valle Long term...Friday night through next Wednesday night. There continues to be disagreement between the GFS and European model (ecmwf) product suites on the track of an upper level low through the Great Basin. The GFS has a slower eastward progression...with the low passing overhead during the weekend. The European model (ecmwf) moves the low out farther south and quickly...leaving eastern Idaho very dry. Taking a cue from ncep's thinking...they have abandoned the GFS solution and are using other models for its preferred solution. Would like to do this as well...but intercede coordination would suffer quite a bit. So have lowered probability of precipitation and sky condition some more starting sun. Still expecting a cold period with northerly air flow and no relief to the cold air through this period. Would like to use colder European model (ecmwf) but again coordination has prevented going much colder. Very little wind expected with the dense cold air continuing. Messick Aviation...ksun should be under northwest flow by the late evening and the strong downslope in this part of Idaho means improving conditions when it develops...which looks around 26/04z. At kbyi...bands of snow will continue through the night...potentially slight improvement by 26/15z if fog doesn't ruin things. Still expecting kpih and kida to have some impact to ceiling and visibility due to snow...but it has been slow to develop. This is why most of the forecasted IFR conditions are only tempo. Kida should be better as the north wind is condition. Messick && Pih watches/warnings/advisories... Winter Weather Advisory until 11 am MST Thursday for idz019>021- 023>025-031-032.
