.UPDATE...
Issued at 639 AM CDT Sat May 24 2025

Webcams and observations show that areas of fog have developed
in far southwestern ND. This fog appears to be dense in some
locations, therefore issued an SPS until 730 am MDT for Adams,
Bowman, and Slope counties. The rest of the forecast remains on
track at this time.

.DISCUSSION...
Issued at 253 AM CDT Sat May 24 2025

A northwest to southeast orientated narrow line of light rain
remains from approximately Williston to Hazen. This line should
dissipate over the next couple to few hours. After which, dry
conditions are expected for the remainder of the morning. A few
showers are then possible at times off weak WAA in the
southwest this afternoon through Sunday night. Any rain that
develops should be light with no more than a couple to few
hundredths of total rainfall at any particular location.

Better precipitation chances at around 40 percent are then
possible from Memorial Day through Wednesday as an upper low
begins to deepen over the Central Plains before lifting into
the Great Lakes Region. At present, the best chances for a
wetting rain are west of the Missouri River and south of I94
Though overall, the heaviest rains are strongly favored to
remain well south of the state. Severe weather isn`t
anticipated, but a rumble or two of thunder isn`t out of the
question either during the afternoon or evening hours.

Temperature trends should remain fairly stable through Tuesday
before a warming trend is favored to close out the week.
Overall, this means highs today through Tuesday will be around
60 in the southwest to low 70s northeast and lows mostly in the
40s. Highs are then favored to reach the 70s across the entire
forecast area by the end of the workweek.

MVFR/IFR ceilings are present in southwestern North Dakota,
along with dense fog in the far southwestern corner. Both
ceilings and visibility are expected to become VFR later this
morning. Once that occurs, VFR conditions should prevail
through the remainder of the period for most locations. The
exception is that there are some hints that fog will redevelop
late tonight in parts of southwestern ND.
