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 Riverton, WY wrote its last area forecast discussion before this winter storm warning went out at Jan 19, 1:16 AM MST, 9 hours 31 minutes earlier.
Area forecast discussion, Jan 19, 1:16 AM MST, 9 hours 31 minutes before
Area Forecast Discussion National Weather Service Riverton WY 116 AM MST Fri Jan 19 2018 .SHORT TERM...Friday through Sunday night Again, with the contrast in the weather pattern, we will split the discussion into West and East of the Divide once again. West of the Divide... So far, things have been a bit slow in evolving with only some light snow across the higher elevations so far. Radar to the west is beginning to fill in to the west however so snow should be widespread by daybreak. At this point, things still look to be on track with the heaviest snow expected during the morning hours which will coincide with the best jet dynamics and frontal passage. Things are rather warm in the Jackson Valley this morning, so there could be some rain at the onset of the precipitation. The models do show a period of heavy snow there this morning. Given that it would likely occur around the morning commute, we will hoist a winter weather advisory for the Jackson Valley. All other highlights will remain as is at this time. The heaviest snow in the northwest should shift out of the area shortly after noon and move to the south and east. Light snow will continue tonight into Saturday but any accumulations are expected to minor. And this brings the next problem as the heaviest precipiation shifts across southern Wyoming. At this time, it looks as though the almost all the precipitation would hold off until after around 5 pm. Snow then spreads into the area from southern Lincoln County to Sweetwater County. At this point, the heaviest snow looks to fall in Lincoln County tonight and then move into Sweetwater County late tonight into Saturday in conjunction with the best dynamics. The models have backed off on QPF just a bit though. However, snow looks to be a near certainty late tonight into Saturday and Saturday night across the I-80 corridor with the highest snowfall amounts the further south and east you go into the county warning are. If there is somewhat of a silver lining it is that with the low further away the pressure gradient will not be that great. There will still be some northeast wind but not as bad as with some previous systems. Snow should end here from northwest to southeast Saturday night into early Sunday as the low moves into the Plains states. As of now most of Sunday into Sunday evening looks dry. Another system will approach the western mountains later Sunday night with another chance of snow. However, we kept POPS low since the models have a bias to rush systems in too quickly in this time frame. East of the Divide... Dry weather will hold through today and also into most of this evening. The main concern today looks to be wind. Windy conditions will continue through the morning across the favored areas from the Red Desert through Casper, although so far most wind has been below warning criteria. 700 millibar winds actually decrease through the day so wind should subside a bit. Temperatures will also be the warmest of the work week, especially in the basins where inversions should finally break. Snow will spread across the area late tonight as a front moves across the area. The main feature with this storm is that the snow looks to be mainly driven by jet dynamics and frontogenesis rather than by upslope as flow is more easterly than northeasterly most of the time. As a result, much of the snow will fall in a band. Continuity has this band from Sweetwater County through the Green Mountains into Natrona County with amounts decreasing to the north and west. At this point, this looked reasonable so we made only minor tweaks to the forecast. One note of caution however, a small shift in this feature could bring heavier snow further north and west so still some uncertainty. For now, we will let the watch ride as is. Warnings and advisories will almost certainty be issued this afternoon though. As for the timing of the heaviest snow, across the Wind River and southern Big Horn Basin, more than likely mid morning into afternoon then tapering off in the evening. Further east, where the region will have a longer influence of the right rear quadrant of the jet streak, steadier and heavier snow will likely persist into the evening, hence the higher snowfall amounts. Again, if there is something good about this system, it will be the wind. By that, I the relative lack off. When lee cyclogenesis takes place, the low will move more easterly, keeping the tighter pressure gradient away from the area. There will still be a breeze, but not as much wind as many other systems. Snow will taper off from northwest to southeast Saturday night and should be out of the area by mid morning Sunday. Mainly dry weather should then continue through Sunday night. Lows Sunday night may be tricky. There will be fresh snow cover. However, some clouds may linger. In addition, the origin of the air mass in Pacific, not Canadian or Arctic, so it will likely be cold but not frigid. .LONG TERM...Monday through Friday A quick moving shortwave trough will push across the northern Rockies Monday with a good shot of some snowfall over the west possibly spilling into northern part of the forecast area late Monday into Monday evening. Models show another transitory/flat ridge Tuesday/Tuesday night with mainly dry conditions except perhaps a slight chance for some snow over the northwestern mountains. By late Tuesday night/Wednesday, global models show a trough pushing into the Pacific Northwest/N. California. Some difluent flow and a moist westerly isentropic upglide flow ahead of this trough should result in snow breaking out across western Wyoming late Wednesday into Wednesday night. Windy to very windy conditions are expected in typical wind corridors Wednesday. This aforementioned trough is then expected to dig, and become a broad trough across much of the western U.S. Thursday into Friday. Global models are in decent agreement with this, but have a good amount of disagreement on timing/track on where the main energy will occur with this longwave trough. For now will broad brush mainly slight valley/chance mountain PoPs on Thursday with an emphasis across the west where the potential for some significant snowfall could occur, and then slight chance across the entire area for Friday. Temperatures in long term will be mainly seasonal to slightly below average. && .AVIATION...00Z Issuance West of the Continental Divide...KJAC, KBPI, KPNA and KRKS A storm system will spread snow to northwest Wyoming today. The snow gradually develops over southwest Wyoming between 18Z and 00Z. The snow will not arrive at KRKS until after 06Z Saturday. MVFR to IFR conditions will prevail in northwest Wyoming today into tonight with mountains frequently obscured. These conditions will develop over southwest Wyoming this afternoon and tonight. East of the Continental Divide...KCPR, KCOD, KRIW, KLND, and KWRL VFR conditions will occur through 06Z Saturday. Snow will be developing after 06Z Saturday with MVFR to IFR conditions becoming widespread by 12Z Saturday. KCPR will see a gusty wind today with the wind decreasing after 01Z Saturday. LLWS will occur in some locations today. Additionally, the Aviation Weather Center will have the latest information on icing and turbulence forecasts. && .FIRE WEATHER... Snow will spread across the west this morning and then East of the Divide tonight and continue into Saturday. Windy conditions will continue from the Red Desert through Natrona County today. Colder temperatures will spread into the area on Saturday and continue into the first part of next week. Mixing and smoke dispersal will generally be fair to poor.&& .RIW WATCHES/WARNINGS/ADVISORIES... Winter Storm Watch from late tonight through late Saturday night for WYZ019-020-022-028>030.
