Area Forecast Discussion National Weather Service Pocatello ID 302 AM MST Sat Dec 1 2018 .SHORT TERM...Today and Sunday...An area of snow showers are noted across the Caribou Highlands and along a line from Lava Hot Springs to Idaho Falls this morning. The gradual progression of the activity is forecast to the east with the bulk of snow forecast over the Caribou Highlands and near the Palisades by sunrise. These areas can expect another 2 inches of snowfall or so before the activity dissipates and/or moves into Wyoming mid- morning. Meanwhile, over in western Idaho, a new area of low pressure is producing snow showers. This low will track toward the Central Mountains of Idaho this morning and begin to accumulate on Galena and Banner Summits as well as across the Wood River Region. For the most part, snow showers will persist throughout the day although a break for a hour or two is not completely out of the question. The heaviest snow is expected this evening as the center of the low passes across the area. This snow will continue to near midnight before taping off some. Light snow is expected to continue throughout the night though as wrap- around moisture encompasses the region through tomorrow morning. In part resulting from our forecast of 5 to 7 inches at pass level, 2 to 5 inches in the valleys and 5 to 8 inches at mountain tops, we will issue a Winter Weather Advisory in effect from this morning through Sunday morning. Areas of snowfall are also anticipated across the Eastern Magic Valley and on mountain peaks in the Southern Highlands. Valley locations will see anywhere from 1 to 3 inches today with peak snowfall this evening. Sunday will be a calmer weather day overall however snow showers will remain in the Central Mountains throughout the day. For the most part the rest of SE ID will be clear of additional showers but forecast models are just not certain in placement at the moment. Anything that does develop will be light and not likely to lead to any issues. NP/DMH .LONG TERM...Monday through Saturday. Very little has changed in the extended period. Monday remains the transition day between patterns. Influence of broad trough over the north central US gives way to weak dirty ridge as next Pacific low moves into California coast. Still seeing good consistency in model solutions with timing of placement of warm frontal/ deformation band precipitation developing near southern border early Tuesday, shifting north across the region by Tuesday night. Overall QPF amounts remain quite low so despite cold temperatures have continued to hold on to low snow accumulations during this time. Upper low reaches coast by Wednesday morning, meanwhile a weak fast moving shortwave trough drops into Montana. Have nudged precipitation chances upward Wednesday and Wednesday night across the region. This precipitation should linger across southeast portions of the forecast area into Thursday as northern shortwave scoots east leaving East Idaho more under the influence of southern low/trough which weakens and shifts east into the Great Basin during the day. All models indicate this feature should exit the region by early Friday, leaving East Idaho under cool northwest flow with ridge redeveloping along coast. Only concern then remains with temperatures. Latest GFS guidance has pushed temps upward slightly, with the coldest lows early Monday and then again Monday night/Tuesday morning. This guidance also now has Wednesday warming up slightly above freezing for lower elevations. The ECMWF is warmer early on, then colder later in the week, but overall spread remains high. Opted for a blend of guidance, but leaned on a high percentage of the previous forecast run to keep changes minimal this far out. DMH && .AVIATION...Small area of moderate snowfall continues just east of KPIH early this morning but satellite imagery shows the back edge of the cloud cover slowly working east. There is a bit of low stratus/fog in the clear area in the middle of the Snake Plain, but anticipate this to be short lived as next feature already located along Oregon coast and cloud cover already working through the western half of the state. So trend should be for a quick improvement this morning to MVFR/VFR most areas with localized continuation of IFR under stratus/fog early in the day. Should then see another decrease in ceilings and vis spread across the region this afternoon, though that may get started late morning for KSUN/KBYI. Moving into the overnight, snowfall focus shifts to southern portions, which could leave KIDA/KDIJ in a quiet period. DMH && .PIH WATCHES/WARNINGS/ADVISORIES... Winter Weather Advisory from 8 AM this morning to 8 AM MST Sunday for IDZ072-073-075. &&
