.SYNOPSIS...
Issued at 349 PM CDT Thu Apr 13 2023

Key Messages:

-Critical fire weather conditions likely through mid evening.

-Isolated thunderstorms possible tonight. Storms will be high based
capable of dry lightning and gusty erratic winds.

-Limited precipitation will be possible Friday into Saturday.

-After cool temperatures Saturday, a gradual warmup Sunday into
Tuesday with a second cold front and increased precipitation chances
Wednesday night into Thursday.

H5 analysis from this morning had a closed low over far southwestern
Mississippi. This was south of a ridge of high pressure which
extended from Indiana, north into Ontario. West of this feature a
strong shortwave and trough of low pressure extended from southern
Idaho into southern California. Southwesterly flow aloft extended
from southern California northeast into western Nebraska and the
Dakotas this morning. Abundant mid and high level cloudiness
extended from the central Rockies into eastern Wyoming, far western
Nebraska, western South Dakota and North Dakota this afternoon. At
the surface, a stationary frontal boundary had sagged into far
north central Nebraska. This boundary was roughly in the vicinity of
Ainsworth, to north of Alliance Nebraska. A surface trough of low
pressure extended from Valentine to just east of Imperial Nebraska.
Across the panhandle into the highway 61 corridor, high clouds were
present while east of this route, skies were mostly clear to partly
cloudy. Very warm temperatures were present for most of the area
this afternoon and 3 PM CT temperatures ranged from 69 degrees at
Gordon to 90 degrees at Broken Bow, Imperial and North Platte.

.SHORT TERM...(This evening through Friday night)
Issued at 349 PM CDT Thu Apr 13 2023

Tonight through Friday night...Isolated, high based,
showers with an embedded thunderstorm or two will be possible early
this evening along a corridor from southwestern into north central
Nebraska. These showers should fire in the vicinity of a weak
surface trough, mentioned above. The latest hires NAM develops a
corridor of elevated instability INVOF the trough with CAPES
approaching 750 J/KG late this afternoon. Mid level lapse rates are
very steep this afternoon across the area with a well established
mixed layer. Looking at the sounding for KLBF from 12z, it is very
dry in the lowest 300mb of the sounding this morning. Cloud bases
for any storms which do develop will be well above 10000 FT AGL.
Given the expansive dry layer below 10000 FT AGL, gusty winds will
be the main threat with any storms which do develop. In addition,
there may be a threat for dry lightning, which could lead to fire
starts (more in the fire section below). The front will be forced
south into western, then southwestern Nebraska overnight. At the
same time, surface low pressure will track from northeastern
Colorado into northwestern Kansas. Behind the front mid level lift
will increase late tonight, bringing an increased threat for showers
across the northern half of the forecast area. As for frontal timing
tonight, the cold front will move very slowly overnight and will
clear the forecast area around daybreak Friday morning. This will
play havoc on high temps Friday with most locations seeing highs
early with steady temps for highs. For North Platte, the low tonight
will be around 50 with a high in the lower 50s for Friday. A
secondary round of precipitation will develop Friday night into
Saturday as the mid level trough crosses the central plains. As the
trough enters eastern Kansas, a closed low will develop and this
will spread a broad shield of precipitation into eastern Nebraska
and Iowa. Behind the front Friday night, temperatures will be cool
enough to support snow. QPF's will remain light however, thanks to
convection INVOF the front in southeastern Nebraska, which will
limit available moisture for snow in central and western Nebraska.
Also, with the past 3 days seeing readings in the upper 80s, have a
hard time believing snow will be able to accumulate on roadways.
That being said, any snow which could accumulate would have to fall
during the nighttime hours and would be confined to grassy surfaces.

.LONG TERM...(Saturday through Thursday)
Issued at 349 PM CDT Thu Apr 13 2023

The upper level trough will track into the mid Mississippi valley
on Saturday night. Dry air and cold air advection will lead to
lows in the 20s, which will be the coldest temps this forecast
period. Sunday will start out windy with diminishing winds in the
afternoon as high pressure builds into western Nebraska. Sunday
will be seasonal with highs in the upper 50s to lower 60s. Ridging
will build back into the area Monday, then transition east of the
area on Tuesday as a trough of low pressure approaches the west
coast. Highs both days will be in the 70s with readings
approaching 80 on Tuesday. A cold front will pass through the area
Tuesday night with a threat for precipitation carrying over into
Thursday. Readings will be cooler both days with highs in the 60s.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1247 PM CDT Thu Apr 13 2023

VFR conditions this afternoon. There will be an isolated chance of
showers and thunderstorms across western and north central
Nebraska late afternoon and evening, with rain and isolated
thunderstorms possible Friday morning, generally across northern
and western Nebraska. There is the potential for gusty, erratic
winds near the thunderstorms. Surface winds this afternoon will
gust near 10 to 15 kts across northern Nebraska, generally out of
the south, but areas across the far northern Sandhills may see a
switch to the north. For the rest of the area winds will be
stronger around 15 to 20 kts with gust up to 30 kts. Across parts
of southwest and central Nebraska there will be a brief period,
generally after midnight, of LLWS out of the southwest around 30
kts. MVFR to even IFR conditions will be possible Friday morning
across western into north central Nebraska, including KVTN and
KLBF terminals.

&&

.FIRE WEATHER...
Issued at 349 PM CDT Thu Apr 13 2023

Critical fire weather conditions will continue through mid
evening across western and north central Nebraska. Along a
corridor from around Hayes Center, to just east of Valentine,
isolated thunderstorms may develop between 5 to 9 PM CT. These
storms will be high based and capable of dry lightning and gusty
erratic winds in the vicinity of storms. The threat for
thunderstorms is expected to end by late evening. Overnight, a
cold front will slowly track through the forecast area. Much
cooler temperatures are expected Friday and Saturday along with a
threat for showers. Conditions will dry out quickly Sunday, Monday
and Tuesday across the area. Minimum relative humidity Sunday,
Monday and Tuesday will bottom out in the 15 to 25 percent range.
Winds on Tuesday will be the strongest and critical to near
critical fire weather conditions have a decent chance of
occurring.
