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 Great Falls, MT wrote its last area forecast discussion before this winter storm warning went out at Mar 14, 11:45 PM MDT, 3 hours 43 minutes earlier.
Area forecast discussion, Mar 14, 11:45 PM MDT, 3 hours 43 minutes before
Area Forecast Discussion National Weather Service Great Falls MT 1145 PM MDT Wed Mar 14 2018 Aviation Section Updated. .UPDATE... 1015 PM Update...Freezing rain is being reported in the Dillon area. Ice accumulations up to a tenth of an inch possible. Up to 10 inches of snow possible in the mountains of Southwest MT. Thus a winter weather advisory issued for Southwest MT until Noon Thursday. Brusda 830 PM Update...Only update this evening was to add mention of patchy freezing fog for Hill and Blaine Counties until the widespread clouds and precipitation move into that area. Otherwise, the current forecast appears to be on track, as precipitation has moved into the area west of Interstate 15. As more moisture advects into the area, precipitation will spread further east across the area overnight. A wintry mix of rain, freezing rain, sleet, and snow will develop over the plains of north central Montana through midnight, but it will then transition over to all snow throughout the night as cooler air aloft moves in. It is still looking like a messy pattern with widespread snow accumulation through tomorrow. Coulston && .SYNOPSIS... An upper level ridge will move eastward tonight, as a strong upper level disturbance moves into the region. Expect rain and snow showers to develop late this afternoon over Southwest MT and then gradually move northeastward and spread into Central MT tonight. Cold air will begin a change over to snow...and possibly some freezing rain or sleet overnight tonight into Thursday morning. Rest of Thursday, expect this colder air keep filtering into the region, continuing chances for freezing rain, sleet or snow over much of Northern and Central MT. Moderate snow accumulations are possible. && .AVIATION... Updated 0545Z. VFR conditions for North-central MT terminals will decline through early morning with areas of mixed precipitation moving from south to north. The freezing rain potential now appears most likely broadly along a line from KGTF to KCTB, with a few hundredths of an inch of icing possible from midnight through around 05z. Precipitation transitions to all snow by 12Z, potentially becoming moderate to at times heavy from KHLN to KGTF to KCTB through 21Z. Conditions gradually improve from south to north Thursday afternoon and evening, with snow changing back to rain in some areas before ending. PN && .HYDROLOGY... Updated 300 PM. The flood advisory will continue for portions of Southwest MT, as minor flooding continues to be reported via emergency managers. Based on local emergency manager feedback, areas that are not flooding could begin to see flooding during the afternoon and evening hours over the next few days. Rain/snow will move into the region this evening through tonight. Overall liquid rainfall should be less than 0.25 inches in most areas, thus significant new flooding issues are not anticipated at this time...however...rain may bring some minor flooding or ponding issues. The remainder of the week will see slightly cooler more normal temperatures...possibly decreasing the threat of new flooding issues. Anglin/Brusda && .PREV DISCUSSION... /ISSUED 300 PM MDT Wed Mar 14 2018/ Tonight through Thursday...Big changes lie ahead in the forecast with the return of winter weather for the entire area beginning tonight. The large and dominant upper-level low continues to pump increasing Pacific moisture across the region this evening and tonight. Within the large counter-clockwise flow around the low, most short-range guidance has finally come to an agreement with the projection of an embedded shortwave trough rotating, and amplifying across the state of Montana late tonight and early tomorrow. Because of this, given increasing dynamic support for low-level ascent, coupled with sufficient moisture aloft, snow will likely develop and expand across the area late tonight through Thursday morning. Details still remain to be seen as far as developing mesoscale features with this system, but it is important to note that where any mesoscale banding occurs, that there could be variations in snowfall amounts across the region. It is still looking likely that higher elevations primarily across central areas and along the Divide will be impacted by significant totals of heavy wet snow that may likely lead to impacts with travel beginning early tomorrow and lasting through the day. Cities in lower elevations including Great Falls and Helena also have the potential to experience heavy, wet snow impacting the morning commute Thursday morning. The next item of concern will be the potential for mixed precipitation in the onset of the precipitation late tonight. With the aforementioned shortwave swinging through the state, ample low-level flow upwards of 50kts from the southeast will help pump temperatures above freezing in the low-levels into eastern areas of the CWA. With this nose of warmer temperatures aloft, periods of freezing rain and sleet look likely which may lead to some impacts, primarily from Great Falls to Havre, including parts of Highway 87 and Highway 2 where some impacts to travel may be likely. Otherwise, this wintry mess will quickly attempt to depart the area to the north by Thursday afternoon and evening, with a small drying period possible Thursday night and into Friday morning. Stay tuned for more updates. KLG For Thursday night through Sunday...most models indicate a rather unsettled period of weather with periods of mostly snow falling. Overall during the day on Saturday looks to be the one period where we should have a break in the precipitation. Overall daily snowfall accumulations of 1 to 3 inches seem possible in most areas. Again, temperatures will remain below normal. For Monday through Wednesday, the GFS/EC have different solutions for the region, as the EC is quite a bit colder, with periods of snow, especially over North Central MT. The GFS is not quite as cold/snowy. Overall, leaned towards a blend for Mon thru Wed, but confidence is low at this time for this period. Brusda && .PRELIMINARY POINT TEMPS/POPS...
