Today and Tomorrow:

Water vapor imagery this evening shows a shortwave pushing
across the Rocky Mountain Front Range while mid/upper confluent
flow fills in to the east of it. Zooming in locally, stratus
lights up nighttime imagery as we find ourselves in a dreary
warm air advection regime to the north of the main surface
boundary stretching from northwest Texas through eastern
Missouri. Model soundings this evening depict subtle lift
through the lowest layers continuing into the overnight hours,
with that low level saturation expected to hold and even result
in spotty drizzle and mist. We`ve nudged up lows overnight due
to the cloud cover, which will limit radiational cooling and
keep ups in the mid-to-upper 30s for most of the area. Just to
the west (and underneath clearer skies), temperatures drop off
quickly and serve as a signal that any breaks in the clouds will
tank temperatures quickly.

By sunrise tomorrow morning, the aforementioned mid/upper shortwave
from Colorado will have arrived to the area, providing continued
lift that still ends up being weak. CAMs are similarly skeptical,
showing limited rainfall output as it passes through the area, due
to the main wave following its own limb of ambient vorticity
directly to its east and limiting PVA. As it moves through, the
western edge of the clouds will begin eroding, with peeks of
sunshine arriving to central to northeast Nebraska by 3 PM.
Temperatures will respond in turn, topping out in the 50s to nearly
60 degrees for points that see some sunshine.

Thursday and Beyond:

Our eyes turn westward Thursday, watching the development of a
neutrally tilting longwave through that will help strengthen a
northward mass response across the pains to its east. That
southerly flow will help boost temperatures and send a swath of
strong moisture advection northward from the Southern Plains
that arrives during the evening/overnight hours. Highs during
the day will see a big jump into the mid/upper 60s, giving us
that taste of late spring with less dry air than our more recent
warm spells. During the evening into the overnight hours, a
potent low-level jet will nose into the forecast area,
increasing the ambient shear and providing a focus for ascent
that could allow showers/storms reach modestly unstable lapse
rates aloft. Showers and storms will lift north-northeast into
the overnight hours, giving us our first meaningful rainfall in
a while, while also giving us the year`s first chances at seeing
severe hail.

By Friday morning, the focus of the low-level jet will have
have shifted to the northeast and we`ll find ourselves focusing
on how much sun we can get during the morning and afternoon
hours to help fuel destabilization. We`ll find a surface
trough/warm front stretching from northwest Kansas into
northeast Nebraska, with steep lapse rates aloft and gusty winds
(30-40 mph) developing to bring our best chance for showers,
and a few strong storms. Latest runs of the ensemble machine
learning guidance indicates that the threat for any severe
storms will be greatest across northeast Kansas into far
southeast, where the main surface boundary intersects with an
unstable and highly sheared (40 kts or more) vertical profile
during the afternoon hours. Any showers and storms that do form
in the warm sector will shift east of the area by the evening
hours, leaving us with lingering post-frontal precipitation and
much cooler air going into early Saturday. As temperatures fall,
we could see some of the rain turn to snow with gusty winds
following behind the main system into early Saturday.

With the larger system from the late week continuing to deepen
and sweep off to the northeast, we`ll find westerly winds
carrying dry but warm winds that help us rebound from a cool
morning into the afternoon with highs forecast to reach the mid
50s. A subtropical branch of the jet stream will ward away any
moisture return to the south and east of the forecast area
through Sunday and Monday, keeping the dry trend and warmer
temperatures going. Though models are in poor agreement at this
point of the forecast, Tuesday into Wednesday will be the next
period to watch for impactful weather as another deep trough
swings into the Plains.

Morning fog has been slow to dissipate, with a longer timeline
than forecast. Have maintained IFR cigs across the area through
20Z when we expect to see some clearing in northeast Nebraska
and clouds to push closer to FL015 at KLNK and KOMA. Some light
drizzle has been reported in western Iowa and the Omaha area.
This may (30%) continue through the evening with a shower
possible in the same areas (

.KEY MESSAGES...

- While most of our forecast area will see only widespread low
  clouds and perhaps some light fog this morning, roughly our
  western 1/3rd stands a better chance of seeing some localized
  dense fog - reducing visibility to around 1/4 mile or less.
  As a result, a Dense Fog Advisory remains in effect for the
  western portion of the area through 11 AM CST.

- Truly measurable precipitation is quite unlikely over the next
  24 hours, although some very light drizzle or a stray shower
  will be possible mainly east of Highway 281 through the
  afternoon hours, with some partial clearing expected for most
  late in the day.

- More widespread, and potentially dense, fog is expected to
  develop across the local area this evening through Thursday
  morning.

- An approaching upper level disturbance will bring increasing
  chances for rain and thunderstorms to the area late in the day
  Thursday, continuing on into the evening/overnight hours.
  There will be the potential for some storms to be strong to
  marginally severe, and the entire area remains in a marginal
  risk for severe weather.

.UPDATE...
Issued at 345 AM CST Wed Mar 4 2026

Another cloudy start to the day is being observed across the
local area with widespread stratus visible on satellite imagery
this morning. Some patchy dense fog is continuing to be
advertised by mesoscale models through the morning hours,
although truly dense fog will be limited to our far western
areas near the edge of the stratus deck over the next few hours.
So far, only a couple locations have seen visibilities drop as
low as 1/2SM in fog, but this could expand a bit across the
advised area closer to sunrise. As a result, have no plans to
trim or cancel the dense fog advisory at this time.

Later today, expect at least partial sunshine to return from
west to east as we transition through the daytime hours, with
temperatures likely to warm about 10 degrees above yesterdays
readings by late afternoon. With the clearing skies and elevated
dewpoints, expect potentially more widespread and dense fog to
re-develop across the entire area tonight, with the 6Z HRRR
showing a fairly wide strip of dense fog developing across the
heart of the local area overnight tonight. SREF probs are also
around 50 percent for fog development tonight, with areas of
fog subsequently added to the forecast for Thursday morning as a
result.

As we transition into the daytime hours Thursday, the focus will
shift to the approaching upper level disturbance crossing the
intermountain west, with surging moisture ahead of this
disturbance potentially leading to thunderstorm development
induced from the LLJ Thursday night. Given the elevated
instability, could see some marginally severe storms across the
local area Thursday evening/night, with hail around the size of
quarters and 60 mph winds both possible with the strongest
storms. Latest SPC outlook has not changed much for the local
area, with a marginal risk for severe weather continuing to be
advertised across both south central Nebraska and north central
Kansas Thursday.

No change in thinking to the remainder of the forecast period
from the previous discussion below.

.DISCUSSION...
Issued at 407 PM CST Tue Mar 3 2026

Currently through tonight...

Been an overall quiet day across the forecast area, with
satellite imagery showing very different sky cover from one
end to the other...across the west seeing mostly sunny skies, in
central and especially eastern areas, socked in with low level
stratus. Looking aloft, upper air and satellite data show an
area of low pressure gradually working its way across northern
CO, with a mid-upper level trough axis extending east-northeast
through NE up toward the Great Lakes. At the surface, the
forecast area is sitting between broad high pressure spread
across portions of the Central Plains up into the Great Lakes
region and deepening low pressure over the TX
panhandle...bringing more NNErly winds to the forecast area,
with speeds have mainly been 10MPH or less. Not surprisingly,
the stubborn cloud cover hasn`t done any favors to temperatures,
keeping those areas mainly in the mid 40s...vs further west in
the sun have reach into the 50s and even some low 60s.

The rest of today on into tonight...models are in good agreement
showing that CO upper low continuing to slide east, main
question will be with whether or not we see any precipitation.
Most models backed off on QPF...but a few models, including some
hi-res, still show the potential for at least some
isolated/scattered sprinkles or showers lingering this evening
and tonight. These chances are mainly focused across portions of
south central NE...and not expecting any notable amounts out of
anything that does fall. Expecting partly to mostly cloudy
skies...with a return of light/variable winds as a surface ridge
axis pushes south through the area. Not out of the question
that some patchy fog could develop later tonight with those
light winds, most models currently showing visibilities not
dropping as low as this morning.

Mid to late work week...

Looking at Wednesday, overall precipitation chances backed off,
with small chances (20 percent) now just confined to SErn
portions of the forecast area. Models remain in good agreement
showing that upper level disturbance current over CO continuing
to slide east right through the heart of the area...but keep the
better precip chances to our SSE. Some models suggest the 20
percent chances currently in the forecast are too much...if that
trend holds, completely removing PoPs is not out of the
question. Winds expected to remain on the lighter side, starting
out the day variable, turning more southerly through the
afternoon ahead of deepening low pressure across the High
Plains. Sky cover is once again expected to diminish from west
to east...but similar to today, confidence in the exact timing
of the clearing is not high. Highs range from the mid 50s in the
east to lower 60s in the west...confidence again lower in the
east due to uncertainty with the cloud cover.

Expecting at least the first half of the day on Thursday to be
dry, potentially most of the day. Precipitation chances will
be on the increase during the afternoon hours, with the overall
best chances looking to be after 00Z. Models showing another
upper level low pressure system working its way into the Pac NW
during the day on Wednesday, digging south with time, ending up
in the Desert SW region by the end of the day on Thursday.
During the evening/overnight hours, larger scale lift is picking
up ahead of this upper level troughing, aided by increasing
moisture/warm advection pushing north thanks to a strengthening
southerly low- level jet. These are not just better chances for
rain, but thunderstorms as well...and with models showing more
instability also working its way in from the south and decent
deep layer shear, some of these storms being on the strong to
severe side are not out of the question. The entire forecast
area is included in the SPC Day 3 Marginal Risk area (main
concern being hail), but models today have trended that better
potential across roughly the SErn half of the forecast
area...will see how things trend over the next 2 days. Outside
of the rain/storm chances increasing through the day, expecting
breezy southerly winds to develop as surface low pressure
deepens over eastern CO...with highs climbing into the mid 60s
to low 70s.

Precip chances Thursday-Thursday night are tied to lift out
ahead of the main upper level system...chances in the forecast
for Friday are tied to the passage of that system itself.
Confidence in chances through Friday night are not high...as
there are some notable differences between models with the
strength of the system and exactly where it tracks. Some keep it
a more closed system, tracking it a touch further NW and
potentially bringing a dry slot to the forecast area, resulting
in little precip...others are more open, tracking more over the
area and bringing better chances. The accompanying surface cold
front is also working its way through the region on Friday, not
doing any favors for confidence in high temperatures...current
forecast has 50s in the NW to near 70 in the SE.

This weekend and on...

Forecast for this weekend into the start of the new work week is
dry, with models showing northwesterly flow aloft in the wake of
Friday`s system turning more zonal with time. The `coolest` day
of this period is Saturday, with highs mainly in the
mid-60s...with forecast highs climbing into the 70s by Monday.

For KGRI/KEAR Airports:

Low ceilings are expected to clear out of the area from west to
east this afternoon. Fog will likely develop overnight possibly
as early as 06z but more likely between 09z and 12z. It is
expected to last until around 15z - 17z. Visibilities down to
1/4 mile are possible, especially around 12z. Winds are expected
to become southeasterly by 21z and will generally be out of the
southeast to south through the end of the period with stronger
winds late tomorrow morning.
