.KEY MESSAGES...
- Strong winds gusting up to 30 to 45 mph at times this morning
into the afternoon.
- Strong southerly winds will combine with dry fuels over
northeast Nebraska to produce extreme fire conditions today
with a Red Flag Warning in effect from 10am-7pm.
- Periodic strong to severe storms will be possible Thursday
evening through Monday, with the best chances Saturday,
Sunday, and Monday afternoon/evenings.

.DISCUSSION...
Issued at 1054 PM CDT Wed May 13 2026
Thursday through Thursday Night...
A ribbon of isentropic lift, seen on the 305K pressure surface, will
sweep across the forecast area Thursday morning with the passage of
a subtle warm front. CAMs have been fairly consistent in firing up a
line of elevated convection along this boundary Thursday morning.
However, showers and weak thunderstorms may have to contend with
quite a bit of dry air eating away the majority of their
precipitation before it reaches the surface.
Southerly winds will increase substantially behind the front
Thursday morning into the afternoon, as a deepening low shifts along
the central CONUS/Canadian border, tightening the pressure gradient.
Gusts as high as 30-45 mph will be possible, with highest speeds
over notably dry portions of northeast Nebraska. Minimum relative
humidity will fall to 20 to 30 percent Thursday afternoon as
temperatures rise into the 80s. A Red Flag Warning remains in effect
for susceptible portions of northeast Nebraska, where dry tall
grasses prevail, and dead vegetation below short green grass
continues to allow for rapid fire spread.
A shortwave disturbance will ripple through the region Thursday
evening, accompanied by a weak cold front, bringing lighter winds
back to the forecast area. A few models hint at the potential for
storms to fire near the front, over Central Kansas, and congeal into
a cluster, glancing the southern half of the CWA Thursday evening
into Thursday night. While deep layer moisture will likely be
lacking, weak instability and 30-40 kts of bulk shear could be
supportive of a severe gust and large hail.
Friday and Beyond...
Temperatures climb even higher Friday, ahead of the next
approaching shortwave. Highs are forecast to reach the low and mid
90s, however they could be hindered slightly by lingering convective
cloud cover. SPC keeps us highlighted in a Marginal to Slight Risk
for severe storms Friday evening, with the potential for storms to
develop along the cold front, progged to be near southeast
Nebraska/southwest Iowa. Large hail and gusty winds would again be
the primary threats.
The cold front lingering over the region will stall as a low
pressure system develops out of the southern Plains, Saturday.
While the exact position of this boundary will likely be
influenced by Friday evening`s convection, storms will likely
fire along it as instability pools in a pocket of 35-45 kts of
deep layer shear. Supercells capable of producing large hail and
damaging winds will again be possible.
An upper trough will dig into the northern Rockies Sunday, as the
Southern Plains low is pushed northeast. A strengthening LLJ will
drive severe storm development in the vicinity of the surface low
Sunday afternoon and evening.
Some of the longer range models hint at another chance for severe
storms as the upper trough ejects eastward over the northern Plains
Monday afternoon and evening.
It is worth noting that lingering convection from Thursday night
could potentially effect storm chances Friday which in-turn would
ripple through chances over the weekend. While Sunday and Monday
currently appear to be the best chance for strong to severe storms,
it would be best to keep an eye out for forecast updates if you have
outdoor plans this weekend.
Temperatures will dip closer to normal next week after a weekend in
the mid to upper 80s. An active pattern looks to continue through
the upcoming week with multiple chance for additional showers and
storms.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1204 AM CDT Thu May 14 2026
VFR conditions are expected to continue through the TAF period.
Light south to southeast winds will begin to increase in speed
tonight as a low pressure system begins to develop west of the
region. A few gusts are anticipated overnight. A low-level jet
will be in place over the area also. Most TAF sites should
remain below LLWS criteria, but OFK will remain near criteria
into the morning. Strong south surface winds develop across the
area by morning with peak gusts of 30 to 35 kts likely during
the afternoon. Winds will begin to weaken late in the afternoon
and evening, but wind speeds remain elevated. During the
afternoon and evening, increasing mid-level and high-level cloud
cover is anticipated, though cloud bases should remain above 10
kft.

991 FXUS63 KGID 140544 AFDGID Area Forecast Discussion National Weather Service Hastings NE 1244 AM CDT Thu May 14 2026 ...AVIATION UPDATE... .KEY MESSAGES... - Red Flag Warning continues for today. Fire weather concerns for the remainder of the week are elevated, but not at Red Flag levels. - There is a 15-20% chance for scattered thunderstorms Thursday, despite the current ongoing dry forecast. Bulk of severe activity is expected to be southeast of the area in central/eastern Kansas. - Saturday afternoon through Sunday night remains the best chance (50-60%) for strong to severe thunderstorms and our best chance at rain. && .UPDATE... Issued at 920 PM CDT Wed May 13 2026 Relative humidity values are improving across the region this evening, and critical fire weather conditions are no longer being observed. For this reason, the Red Flag warning was cancelled. && .DISCUSSION... Issued at 234 PM CDT Wed May 13 2026 A more active pattern is setting up as zonal flow transitions and a trough sets up over the western half of the country this weekend putting the Plains under southwesterly flow aloft. Thursday-Friday: Southerly surface level flow will be strong, beginning in the overnight hours tonight and continue through Thursday. This will help advect up higher dew point temperatures. Models are quick with this moisture return, but there are some reservations as to how far north the higher dew points will get. Along and ahead of the front, some models indicate that there may be enough moisture transport in a narrow corridor (aided by today`s southerly winds over the High Plains) to support thunderstorms during the afternoon hours. The current forecast is dry, but for areas along and west of Highway 183, there is a 15-20% chance for thunderstorms. Instability across the remainder of southern Nebraska looks marginal at best, while the best conditions for strong to severe thunderstorms looks to be across central and eastern Kansas just to the east of our forecast area. Temperatures will be warm for the end of the work week, but current forecast highs could be slightly overdone and tried to taper them down slightly with this forecast, especially where low level moisture begins to increase across southern and southeastern Nebraska. Saturday - Monday: The weekend also looks warm, with temps generally in the mid- upper 80s. Confidence is low that the weekend, despite all the rain chances, will be a rainout. The primary concern is that many will not see much rain that the drought stricken area is desperate for. There will be a number of weak waves ahead of the main disturbance that looks to eject northeastward on Monday. These weak waves will bring chances for precipitation and some severe weather to the area for the weekend, the main time period looks to be Saturday night and again Sunday afternoon and overnight. Uncertainty remains high in the central part of Nebraska/Kansas for where the best low level moisture and surface front will be and thus where thunderstorm activity will fire, especially on Sunday. There is a chance that we could generally be quiet, watching activity in Eastern portions of Nebraska and Kansas. This uncertainty persists for Monday with precipitation and temperatures. If the front has moved through, it could be a much cooler day than is currently indicated in the forecast. && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 1149 PM CDT Wed May 13 2026 For KGRI/KEAR Airports: Moderately high confidence VFR conditions through the period with strong LLWS to start and a small chance for a -SHRA or -TSRA during the late afternoon through early evening hours. Latest VWP continues to show 50 KT winds just 1KFT above the ground with strong LLWS occurring at both terminals. Expect the axis of this jet to shift east by daybreak, with surface winds then increasing and gusting to around 30 KTS through the morning hours before gradually diminishing from west to east around midday. Expect an upper level disturbance late in the day to then potentially provide enough forcing for a few -TSRAs as depicted in some of the CAMs...with this activity diminishing by 15/03Z or so. That said, confidence in a -SHRA or -TSRA at either terminal is low (~15%), so no mention was made in the current TAFs. && .FIRE WEATHER... Issued at 234 PM CDT Wed May 13 2026 Beyond today, Fire Weather concerns will remain, but Red Flag conditions are not as likely primarily due to the increase in low level moisture. Despite dry conditions (RH 18-25%) expected Thursday afternoon over areas along and west of Hwy 183, the strongest winds will have moved east of the area. On Friday winds remain light despite dry conditions (RH values in the teens) for much of western Nebraska. Through the remainder of the weekend, RH values are expected to increase with the influx of the low level moisture despite the breezy winds at times. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None.
