.UPDATE...
Issued at 848 AM CST Tue Nov 18 2025

Low stratus continues across the state. There are few showers
moving into the James River Valley. Quiet weather continues
across the state no updates are needed at this time.

UPDATE
Issued at 551 AM CST Tue Nov 18 2025

Isolated rain showers continue early this morning mainly over
south central ND, while those in the northwest have dissipated.
CAMs suggest remaining showers will dissipate over the next
couple to few hours as well. As these rain showers head
eastward, temperatures are simultaneously rising. Therefore, any
freezing rain is unlikely at this time.

.DISCUSSION...
Issued at 316 AM CST Tue Nov 18 2025

A little light rain continues passing through central North
Dakota early this morning, with light returns approaching the
far northwest. However, temperatures remain in the mid 30s for
central parts of the state. Therefore, the probability for
freezing rain this morning remains low in the central. The
far northwest, on the other hand, is colder. But returns up
there appear pretty light with little evidence of anything
reaching the surface. As such, not expecting much more than
flurries or sprinkles in the northwest this morning. Either way,
any light precipitation within the state should end towards
sunrise, or shortly thereafter. Mostly dry conditions are then
expected for the day today before another shortwave potentially
brings light rain passing from west to east tonight and into
Wednesday morning. Lows where mentionable PoPs are present
generally remain above freezing. So unless skies clear prior to
rain falling (not the favored solution at this time), freezing
rain potential tonight seems pretty low as well.

For the remainder of the week, mostly dry zonal to northwesterly
flow aloft is forecast. Without a particularly cool airmass in
place, this will maintain above average temperatures for most
locations, most days, as highs generally remain in the 40s to
low 50s. Cooler highs in the upper 30s are forecast in the
northeast and Turtle Mountains at times. However, average highs
in those areas are already less than 35 degrees, while areas
further west and south are closer to 40 degrees. Lows are also
expected to remain above average and mostly in the upper 20s to
mid 30s, though are progged to become a bit cooler at for
Wednesday and Thursday nights.

For next week, trends favor much cooler conditions next week,
though NBM ensemble temperature spreads remain high. In
addition, the CPC also continues to favor above average
precipitation. Bear in mind, above average precipitation for
this time of of year is only around 15 hundredths of liquid
equivalent, or approximately any system that drops 1 to 3 inches
of snow.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 551 AM CST Tue Nov 18 2025

Isolated light rain showers are present mainly in south central
ND. These should fully dissipate over the next couple to few
hours. There are some MVFR ceilings present in the south central
near the ND/SD border that may persist through at least the
morning. However, while the probability isn`t zero, these are
not favored to impact any terminals at this time. Otherwise, VFR
ceilings and visibility are expected through the period.

.BIS WATCHES/WARNINGS/ADVISORIES...
None.
