.SHORT TERM...(Today through Monday Afternoon)
Issued at 249 AM CDT Sun Apr 30 2023

Lingering clouds will exit southeast this morning, but linger east,
closer to the stacked sfc to 500mb low near Lake Michigan. This
will keep north to northwest flow at 500mb through the period, as
the low shifts to the southeastern Ontario and northern NY Tuesday
afternoon. High pressure at the surface will be set up across
central Canada to start the day today, with a ridge extending
across the western Dakotas and NE. We'll still have that tight
pressure gradient over eastern SD and western MN with mixing to
around 750mb(closer to 800mb near the James River) this afternoon
where it will tap into slightly stronger winds. Wind gusts of 30
to near 45 mph still look likely over eastern SD, with the
strongest winds across the Sisseton Hills and east. Have gone
ahead with a low end Wind Advisory across our eastern 1-2 tiers of
counties.

Fire weather wise, the driest air and driest fuels (grasses) will be
west of the Missouri River where relative humidity values will fall
into the 20 to 25 percent range. This will contrast with the 35 to
45 percent range east. The surface high will continue to sink south
with the ridge spreading across much of the rest of the area. With
that will be slightly less wind but lower relative humidity values
of 20 to 35 percent. Wind gusts of 30 to near 40 mph could still be
possible over our eastern forecast area.

.LONG TERM...(Monday Evening through Saturday)
Issued at 249 AM CDT Sun Apr 30 2023

The main forecast challenge in the extended is precipitation chances
toward the end of the period. The region will be situated between a
large upper trough over the eastern half of the country and a ridge
over the Rockies to start the period. The ridge will gradually work
its way eastward to over the central part of the country by the
middle of the week, before getting pushed east later in the week as
shortwave energy swings across the Northern Plains Friday and
Saturday.

At the surface, high pressure will be the dominant feature over the
region Monday night through early Wednesday, with the region then
becoming situated between the exiting high and low pressure to the
west. This will allow for decent warm air advection to develop
Wednesday and Thursday. Will then see increasing chances for
precipitation Thursday night through Saturday as the low pressure
system to the west slowly works its way across the central part of
the country. At this time, it looks to be more of a scattered shower
type pattern, but cannot rule a few thunderstorms Friday afternoon
and again Saturday afternoon as some weak instability develops.

High temperatures will be in the 50s and 60s Tuesday, in the 70s to
lower 80s Wednesday and Thursday, and in the 60s to lower 70s Friday
and Saturday. Overnight lows will be in the upper 20s to lower 30s
Monday night, in the 30s to lower 40s Tuesday night, and in the 40s
Wednesday night, Thursday night and Friday night.
