.UPDATE...
Issued at 1245 AM CDT Mon Apr 27 2026

Showers continue over portions of western and south central
North Dakota at the time of this mid night forecast. Near
surface conditions across south central North Dakota are little
more dry than anticipated, with dewpoint depressions of 15 to 25
degrees being pulled further south than previously forecast.
CAMs are picking up on this trend as well, keeping precpitation
across this area fairly scattered. Have opted to lower PoPs a
bit to account for this trend. Cooler temperatures across
portions of the west have allowed for a transition over to snow
to occur a little more quickly than previously expected, with
visibilities dropping as low as 2 to 3 miles when and where snow
is falling. Have adjusted the timing of the rain to snow
transition across the west accordingly with this update.
Otherwise, no major adjustments to the forecast were performed
at this time.

UPDATE
Issued at 1001 PM CDT Sun Apr 26 2026

Widespread rain across my southern 2 tier counties, with
continued light snow northwest. Ceilings starting to drop along
the I94 corridor now as moisture continues to push northward.
Adjusted POPs based on these trends and latest radar imagery.
Other forecast changes were minor.

UPDATE
Issued at 703 PM CDT Sun Apr 26 2026

The forecast for tonight remains mainly on track. Adjusted POPs
a bit to delay the arrival of precipitation, though these
changes were minor. Rain is rapidly developing and advancing
north into southern areas of the state ahead of a northeastward
moving embedded impulse, with another area of rain and snow
along and north of a sfc trough from parts of eastern Montana
into northwestern North Dakota. Will make adjustments to the
forecast as needed this evening.

.DISCUSSION...
Issued at 220 PM CDT Sun Apr 26 2026

Currently the famous upper level low that hasn't moved much in
the last few days, has actually shifted north. There is a trough
extending off the center down to northern California, leading to
southwest flow across most of the rest of the CONUS. At the
surface the Colorado Low is just forming on the mountain, but
widespread rain is already on going in the Central and Northern
Plains in the southwest flow. In eastern Montana and far
northwestern North Dakota scattered snow showers have been on
going. Little to no accumulations are expected. The bulk of the
rain showers are located in central and southern South Dakota,
along and south in Interstate 90. Temperatures today are
slightly warmer and near normal as the southwest flow has some
warm air advection.

This evening the surface low will wrap up and move northeast,
bringing the rain north into the state. It is expected to then
continue raining through Monday morning in most of the state
besides the far north. As in prior forecast runs, the NBM
continues to move the bulk of the QPF east into Minnesota and we
are now left with less than 0.50 inches in the entire CWA. The
highest QPF amounts will likely be in far southeastern North
Dakota where 1 inch could fall.

With the strong surface low exiting the Northern Plains Monday
morning, there will a tight pressure gradient and a slight
pressure bubble in southeast North Dakota... it will be windy.
The James River Valley will be the bullseye where gusts up to 45
mph are possible from the north. We held off on a Wind Advisory
on this shift but will likely be needing one. The NBM was
blended with some NBM 90th to just slightly boost the winds with
the drier, cooler air.

The rest of the week will be drier with multiple shortwave
ridges, eventually leading to quasi-zonal flow possible late in
the week. This in turn will lead to a slight warming trend
where we could see temperatures return to near normal or above
(60F) by Thursday.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 1245 AM CDT Mon Apr 27 2026

Precpitation will promote MVFR to IFR ceilings across portions
of western and south central North Dakota overnight, slowly
improving from northwest to southeast through the day Monday.
While much of this precpitation is expected to fall as rain,
light snow is possible over the west, which could promote MVFR
to IFR visibilities when and where it falls. VFR conditions are
generally expected to persist across the north central. North
to northeast winds are expected to strengthen overnight through
this morning, becoming gusty over portions of south central
North Dakota late Monday morning through the afternoon, before
diminishing through the early evening.

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