.SHORT TERM...(Today through Thursday Afternoon)
Issued at 340 AM CDT Wed May 22 2019

The very short term looks to calm down a bit over the next day or
so. Strong system currently entering southeast South Dakota will
continue to move north and east and fill as the day progresses. As
that occurs, winds will diminish, and waa band of pcpn will have
rotated mostly out of the cwa by noon. However, sct pcpn will remain
possible through the day as the upper low shears across the region.
With plenty of clouds around today, temperatures will only slightly
recover from Tuesday's levels.

For tonight and most of Thursday, sfc high pressure builds south
over the area. This should bring a reduction in clouds, but perhaps
not complete clearing. Light winds settle in over the region tnt,
but probably will be offset some by clouds, so didn't tank
temperatures, especially over the James valley.  With some sun,
the mercury should recover some on Thursday afternoon.

.LONG TERM...(Thursday Evening through Tuesday)
Issued at 340 AM CDT Wed May 22 2019

Next wave of low pressure moves northeast across the area Thursday
night into Friday morning, with more rainfall almost a certainty
once again over a widespread area. This system will be moving
through quicker than the current one over us, so expect amounts to
be generally less than an inch. Friday is shaping up to be an
interesting day, as initially, we'll still be dealing with clouds
and precip in the morning, especially over the northern CWA. But, by
afternoon, models are in good agreement in bringing a surge of dry
air into the region as southwest winds and strong warm air advection
take over. Clouds should depart rapidly to the north throughout the
day. This sets the stage for a decent warmup by afternoon, with
highs in the 60s to low 70s. In fact, would not be surprised if
forecast highs come up a few degrees over the next few forecast
shifts. Saturday still appears to be a dry day for right now as
surface high pressure moves across the area. The pattern continues
to be active as we head into early next week, with another decent
looking system moving in Monday night into Tuesday.
