.DISCUSSION...
Issued at 108 AM CDT Wed May 13 2026

As of 1 AM CDT, temperatures around the area are in the mid to upper
40s with winds generally out of the north at 10 mph or less. Winds
east of the MO River are expected to be lighter than the last few
days, at least during the daylight hours, generally staying below 25
mph. West river, wind gusts this afternoon will gust up to 30 to 35
mph prompting a Red Flag Warning from 11 AM to 10 PM CDT (10 AM to 9
PM MDT).

Not much change in the forecast for the next several days. Elevated
fire concerns continue through the rest of the work week with wind
gusts of 35 to 45 mph Thursday and Friday, again, localized gusts of
50 mph possible mainly along the ND border. Relative humidity values
do not recover much at all overnight Thursday. Therefore, a Fire
Weather Watch is in place extending from 1 PM CDT Thursday through
10 PM Friday for areas along the James River and west. Areas to the
east of the James River are added to the watch Friday at 11 AM CDT.
Also with these strong winds will be the potential for blowing dust.
The blowing dust model shows an area of dust moving in from western
SD Thursday morning as the cold front moves into the area. Above
average temperatures continue as well with Thursday still expected
to be the warmest. The next chance for precipitation continues to be
Saturday night through Monday. The timing of heaviest rain is during
the day Sunday when the chance of more than a quarter of an inch is
about 60 to 70% around and east of the Missouri River. This is an
increase from previous forecasts. If this trend continues we could
get enough precipitation to complete green up and hopefully reduce
fire weather concerns. Additional precipitation Monday has a 35 to
45% chance of exceeding a tenth of an inch.
