.DISCUSSION...
Issued at 345 AM CDT Tue Jun 10 2025

Skies are clear across the area this morning apart from some
high-level smoke obscuring the moon, turning it red. This
morning we sit under northwesterly flow aloft as a ridge builds
over the Rockies to our west. As this ridge expands eastward
today, we`ll see a warm front move west to east across our area
shifting winds to southwesterly and advecting in warmer
temperatures. With this, we`ll see high temperatures soar into
the upper 80s today, with some locations hitting 90 if we
overachieve by even a degree or two.

The upper-level ridge broadens and flattens out as it expands
eastward across the western 2/3rds of the CONUS. This allows for
a fairly active zonal flow pattern to set up through the end of
the week. The first in the series of shortwaves to move through
will enhance moisture/warm air advection across eastern Nebraska
leading to likely the warmest day of the year so far with highs
in the low-to-mid 90s. Because of the enhanced moisture
advection and a stationary boundary setting up along the
Nebraska/South Dakota state line, we`ll see storm chances
develop mainly over northeast Nebraska and west-central Iowa
Wednesday afternoon through Wednesday night. SPC indicates a
Marginal Risk (level 1 out of 5) for severe storms with this
system, threats mainly being winds and hail.

Temperatures through the end of the week will remind us that it
IS in fact June, with highs in the mid-to-upper 80s. The next
clear shortwave to pass through will be Thursday night into
early Friday, bringing more widespread chances for storms across
eastern Nebraska and western Iowa as a low pressure system
develops on the Lee side of the Rockies and moves eastward out
of Wyoming into Nebraska and South Dakota. As this system
deepens, we`ll see the development of a cold front that will
sweep across Nebraska Thursday afternoon and evening, bringing
storm chances initially to north-central Nebraska, then
expanding southeastward along the front as the low-level jet
kicks in overnight. This will also have a Marginal Risk for
severe weather, with primary threats again being wind and hail.

Through the weekend we`ll continue to see afternoon/evening
chances for showers and storms, though forced via more subtle
features. Overall the severe threat Saturday and Sunday appears
low at this time. High temperatures will hover right around 90
degrees Saturday and Sunday, with overnight recovery (low
temperatures) in the low-to-mid 60s. A great weekend to go to
the pool, but make sure you monitor the weather and get out if
any storms develop nearby.

Monday, we`ll have to monitor a more substantial trough moving
across the Northern Plains for another better chance for severe
weather somewhere across the Northern Plains as far south as
Nebraska.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 553 AM CDT Tue Jun 10 2025

VFR conditions to prevail through the TAF period. Watching an
area of patchy fog/haze which has developed west of KOFK. If it
does move into KOFK, we could see MVFR/IFR vis through 13-14Z.
Probably won`t become dense. KOMA and KLNK should remain clear.
Winds today will be light out of the southwest, becoming more
southerly later in the day.
