A notable increasing temperature trend has begun across eastern
Kansas and western Missouri as of the early afternoon, coincident
with southwesterly surface winds and resulting warm advection on the
back side of a departing surface ridge. Dew point values have also
increased slightly, though elevated fire weather concerns will
persist through the afternoon given the large temp/dew point
spread and resulting relative humidity values in the 30 percent
range. While a ridging pattern continues to advect overhead this
evening, a deepening mid-level trough will make its way inland
across the west coast, eventually stalling across the Four Corners
by Monday. A shortwave trough will eject ahead of this feature
late Sunday, atop the local warm sector. Still anticipating
showers and thunderstorms beginning late Sunday evening into the
overnight hours throughout the area. Conditions look to cooperate
nicely for Easter festivities in the morning and afternoon. The
only caveat will be with gusty conditions throughout the day as a
surface low strengthens across central Kansas. Expecting gusts up
to 35 to perhaps 40 mph out of the south during peak heating
Sunday. Afternoon highs will also rise into the lower 80s,
approximately 10 to 15 degrees above normal values.

Scattered rain showers and thunderstorms will develop within the
warm sector late Sunday, and continue off and on through Monday
until the attendant cold front pushes through the area on Tuesday.
The frontal boundary will be slow to push through as the
southwestern trough deepens, eventually forming a cut-off low to
the south. This will also help to maintain precip chances behind
the front as shortwave energy continues to eject northeast of the
trough, overhead the local area. While precip chances are possible
over a multi-day period, overall rainfall totals should be
limited to a quarter to a half inch or less across most areas.
Additionally, severe weather is not anticipated at this time
through the early week.

Above normal temperature trends will resume in the wake of the early
to mid-week activity as a broad ridging pattern develops upstream.
Dry conditions will then give way to another round of rain shower
and thunderstorm chances by next weekend.

Mainly a wind forecast with winds up through sunset, then lighter
overnight. Wind shear will pick up assuming full decoupling with the
boundary layer, which is expected. Once daytime mixing picks up
after sunrise expect winds to gradually increase through the day.
