Generally quiet conditions and seasonable temperatures are expected
over the next several days as upper-level high pressure currently
over the southern Plains continues to retrograde westward and brings
northwest flow back across the region. At the surface, high pressure
will drift very slowly to the east, allowing light southerly winds
and a bit more moisture to seep back into the region beginning
tonight and continuing into the weekend, bringing dewpoints back
into the upper 60s to near 70, and max heat indices back into the
mid to upper 90s most afternoons. A few disturbances may ride down
the ridge and into the region during the forecast period, but will
be somewhat difficult to pin down both spatially and temporally.

The first ridge-riding shortwave trough will drop southeastward on
Friday and may allow a few thunderstorms to develop across eastern
Nebraska, which could translate southeast into the region late
Friday evening into the early overnight hours. Storms will likely
weaken and diminish in intensity as they sink southward away from
better upper-level flow and forcing, so have reduced PoPs after
midnight and south of the MO river. A similar situation is possible
on Saturday night; however, storms will likely develop and stay
farther to the north. Confidence with the presence and location of
any storms during this late work week and weekend period are fairly
low, and most areas likely will not see rain until next week.

Precipitation chances increase early next work week as northwest
flow amplifies and a few stronger shortwave troughs push directly
into the forecast area. Currently, the best chance for precipitation
should come Tuesday night into early Wednesday, and again Thursday
night into early Friday; however, precipitation is at least possible
in nearly every period of the mid- to long-range forecast. Humid
conditions and seasonable temperatures are expected to continue with
highs in the lower 90s and lows in the upper 60s to lower 70s, until
perhaps the end of the period when a boundary potentially sets up
south of the forecast area and allows cooler northeast flow to sink
into the region.

VFR conditions are expected through the forecast. High pressure over
the area will keep winds light with only high clouds expected
overnight and into tomorrow morning. By Friday afternoon, returning
moisture may lead to diurnal cumulus develop but cloud bases will
remain VFR.
