.DISCUSSION...
Issued at 320 PM CDT Thu Jun 6 2024

CURRENT THROUGH TONIGHT: Breezy northwesterly winds continue
across the region, with latest observations showing sunny skies,
highs in the 70s, and gusts ranging between 40 to 50 MPH. Should see
these conditions continue through the late afternoon, with gusts
forecast to quickly subside near sunset. As such, believe the current
Wind Advisory remains in good shape, which is set to expire at 7 PM.
Otherwise, look for light and variable winds to prevail overnight
under clear skies, with lows falling into the upper 40s to lower 50s.

FRIDAY: Winds turn south/southeasterly Friday as sfc high pressure
expands into a ridge across our area, with highs forecast to rise
into the upper 70s to lower 80s. This will be short-lived though, as
a sfc low pressure quickly develops on the backside of the ridge.
WAA ahead of this feature will result in scattered showers and
storms across the region for most of the day, with a few strong to
severe storms possible along the MO River Valley during the evening.
While there is ample bulk shear in place (>40kt), overall
instability remains rather meager (<1000J/kg). Thus, believe quarter
size hail, damaging gusts between 50-60 MPH, and brief heavy
downpours would be the primary hazards. In regard to rainfall
totals, still looking at anywhere from a few hundredths to a tenth or
so.

SATURDAY THROUGH SUNDAY: Another sfc high pressure slides over the
region Saturday allowing dry conditions to prevail through the
weekend. Afternoon highs will be a touch cooler during this time,
with temperatures largely in the low to mid 70s under partly cloudy
skies. North/northwest winds will also remain fairly light, so get
outside and enjoy the weather if you can!

MONDAY AND BEYOND: Model consistency begins to wane heading into the
new week as a pronounced upper level low dives southeastward across
the Northern Plains. Still quite a bit of variability in place,
though the general consensus is that showers and storms will be
possible Monday afternoon through Tuesday morning. Don`t want to
speculate too much though, so will continue to leave model blend of
PoPs as is until confidence increases. Otherwise, should see largely
dry conditions and above normal temperatures prevail for the
remainder of the extended period as mid-level ridging expands across
the central Plains.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1231 PM CDT Thu Jun 6 2024

VFR conditions are expected to prevail this TAF cycle, with breezy
northwest winds still the main concern. Latest observations show
gusts ranging between 35 to 50 MPH. Should see this continue for
much of the afternoon, with gusts quickly diminishing near sunset.
Direction then become light and variable overnight. Otherwise, look
for shower and storm chances to return after daybreak Friday, a few
of which may become strong to severe during the afternoon.
