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 Jan 11, 10:33 AM MST, 4 hours 19 minutes earlier.

Area forecast discussion, Jan 11, 10:33 AM MST, 4 hours 19 minutes before

Area Forecast Discussion
National Weather Service Great Falls MT
1033 AM MST Sat Jan 11 2020

.SYNOPSIS...

Moist westerly flow aloft will keep cloudy conditions across the
region today with continued mountain snow, especially along the
Continental Divide. Seasonable temperatures today will give way
to an arctic cold front moving south through the region on Sunday.
Another round of widespread snow is expected Sunday into Monday,
along with very cold temperatures moving into the region. Expect
the very cold temperatures to last through much of the week.

&&

.DISCUSSION...

&&

.AVIATION...
Updated 1030 AM MST Sat Jan 11 2020 (18Z TAF Period)

Expect mainly VFR through much of the TAF period. Exceptions
include KWYS, where current VLIFR/LIFR/IFR conditions should
improve to at least MVFR and possibly VFR toward 22Z. KHVR will
see a chance of snow and slightly reduced visibilities after
02Z as the arctic front makes its way south across north-central
Montana. Generally southwest winds will occur along and south of
the front, becoming more northerly north behind the front.
Mountains/passes will likely obscured for much, if not all, of the
period.
