KEY MESSAGES

- Largely dry conditions are expected until rain with a few rumbles of thunder possible arrive from the south tonight, favoring central Nebraska.

- After a dry bulk of the day, rain and thunderstorms again become possible late Saturday afternoon with a few stronger storms capable of gusty winds and isolated severe hail.

- Warmer temperatures return for early next week, coinciding with an increased concern for fire weather conditions. A Fire Weather Watch has been issued for much of western Nebraska on Sunday as a result.

SHORT TERM /THROUGH SATURDAY NIGHT/

Issued at 354 PM CDT Fri Apr 10 2026

Earlier this afternoon, an influx of recycled/rain-cooled air stymied the warm-up for most locations. Readings have only managed to reach the low to middle 50s as of 19z (2pm CDT) with persistent east/southeast winds around 10-20 mph with gusts as high as 25 mph at times. Skies were partly to mostly clear with altocumulus crossing the region west to east. This hints at some modest instability in place with the early afternoon. While the 18z RAOB from LBF didn't explicitly show measured instability, steep lapse rates certainly helped and even an isolated thunderstorm tracked across Hayes and Frontier Counties with copious lightning but little in the way of rainfall.

For tonight, expect winds to continue to veer to the south by this evening. Resulting warm air/moisture advection will lead to increasing low cloud cover and rain potential. The forecast relies heavily on HREF output for timing, which shows a 10pm CDT arrival in our south with activity then lifting north and east through early Saturday morning. This will be tied to a strong LLJ with continued veering winds leading to the focus shifting to eastern Nebraska/South Dakota towards daybreak. Given modest instability in place Friday afternoon and the expected influx of elevated instability tonight, have opted to include a Slight Chance (15%) mention of thunder for central Nebraska. This is expected to occur over top saturated low levels where patchy fog was introduced into the forecast. Instability should be rooted around h85-h7 and be weak at best thus severe weather is not expected but a few rumbles of thunder and even some lightning cannot be ruled out. QPF will be limited, favoring south central and eastern Nebraska where NBM highlights 50-70% and 30-50% for exceeding 0.10" and 0.25" respectively during the overnight. While a few locations may surpass 0.10" locally, driven by convection, most locations may struggle to exceed 0.05".

Saturday...morning precipitation should depart to the east by daybreak leaving much of the daytime dry. Upper-level height falls will begin to spill onto the central High Plains as the next disturbance lifts north and east out of the Four Corners region. Lee troughing will lead to the formation of a weak low invof the Nebraska Panhandle/southwest South Dakota. This will drag a surface trough/dryline off the higher terrain. Storms should initiate off this boundary to the west by late afternoon and move east/northeast. As they do, they'll encounter the richer airmass of west central Nebraska where instability should be greater with similar shear thanks to afternoon highs in the 70s to low 80s. This would support an increasing threat for strong to perhaps briefly severe thunderstorms. The latest outlook from the Storm Prediction Center extends the pre-existing Marginal Risk (level 1 of 5) further west to encompass this threat. With MLCAPE nearing 1500 j/kg coincident with 30-35 knot 0-6km BWD, multicell and brief supercell structures appear possible. Limiting confidence is fairly modest lift and increasing capping heading into the evening hours. HREF/NAM output shows a cluster of storms lifting north and east out of Colorado and into portions of western Nebraska between 6pm-Midnight and believe the Marginal Risk captures this potential well. Any strong to severe storm may be capable of 50-60 mph gusts and 1.00-1.25" hail. Rainfall will be closely tied to where storms form and so variability is possible with subsequent forecasts. For now, greatest confidence appears closely tied to the western Sandhills towards the Platte Valley where a few locations may approach a quarter of an inch.

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 354 PM CDT Fri Apr 10 2026

Sunday and Monday...Southwesterly flow will start the new week as deep troughing continues to approach the West Coast. A few embedded perturbations will ride up the departing ridge and bring a few changes to the sensible weather. Increased lee troughing on Sunday will support a flip to westerly downsloping winds with continuation into Monday. This will coincide with the two warmest days of the forecast as highs reach the upper 70s in the west to middle 80s. Fire concerns will also be on the increase with details pertaining to that below in the Fire Weather section. High temperatures are not expected to threaten records at this time but will certainly exceed 15F above normal for mid-April. Weak low pressure will form across South Dakota late Sunday night and drag a dryline east through far western Nebraska. This will buffer any richer low-level moisture to the heast of Highway 83 (potentially Highway 183). It's these areas that should see the greatest potential for precipitation. While the NBM paints some low-end potential, belief is this is unlikely to manifest into anything beneficial for the area and so later forecasts may need to reduce PoPs to account for this.

Tuesday and beyond...height falls continue Monday evening into Tuesday as longwave troughing approaches from the west. Though subtle timing differences exists in deterministic solutions, generally reasonable agreement is in place from trough ejection onto the Plains sometime early Tuesday. Synoptic lift peaks early Tuesday across western Nebraska as low-level Q-vector convergence maximizes. Near to slightly above normal moisture quality with strong lift will support increasing rain and thunderstorm potential. Latest NBM probabilities paint upwards of 50% potential for exceeding 0.10" Tuesday evening into early Wednesday across our western zones with about 25% potential for exceeding 0.25" over the central Sandhills. Current PoPs approach 65% with with non-zero instability in place, believe some convective elements could lead to locally heavier amounts. Details are far from certain so stay tuned. Temperatures will fall slightly for our western zones Tuesday as highs only reach the middle 60s with middle 70s elsewhere to the east. Slightly warmer temperatures return on Wednesday with further warming for Thursday. While fire weather concerns appear possible again, confidence in precise details and potential for light precipitation in the area casts some doubt on certainty. By late week, a deeper trough will dive out of the Pacific Northwest and take aim on the Central Rockies by the end of the forecast period. Reasonable agreement in mid-range models suggests local impacts possible Friday into Saturday to include more low-end rain chances and a slight cooldown.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1236 PM CDT Fri Apr 10 2026

VFR conditions are expected through the remainder of the daytime Friday before increasing low clouds and precipitation working in from the south lead to degraded conditions.

Surface high pressure will pass across northern Nebraska with a return to southeasterly and then southerly flow. An increasing LLJ will produce some LLWS concerns in addition to gusty winds at both terminals. Resultant moisture advection will also support rapidly lowering CIGs with IFR/LIFR expected across portions of southwest and central Nebraska, and MVFR further north and west. While light rain/drizzle is possible with this activity, confidence is limited with HREF probabilities of measurable rain limited to around 10-15% and so will omit from the forecast at LBF.

Clouds should be slow to break towards the end of the period and so refinements to timing and magnitude of impacts will likely be needed with later forecasts.

FIRE WEATHER

Issued at 354 PM CDT Fri Apr 10 2026

Sunday/Monday...Fire Weather Watch has been issued for Zones 204, 206, 208, and 210. Concern is westerly downsloping winds with afternoon highs reaching the upper 70s to lower 80s (15-25F above normal). West winds appear likely to gust in the 25 to 30 mph range but it'll require deep mixing to achieve this. Forecast soundings show sub 20 knot winds below h6 (3km AGL) so any reduction in mixing heights could lead to weaker winds and limit overall concern. Given afternoon highs above normal with mid 20s dew points, afternoon humidity values should fall below 20% for all locations and below 15% for areas west of Highway 183. Poor humidity recovery appears likely with westerly winds continuing into the overnight. Mild temperatures and low to middle 20s dew points will only support peak recovery around 45-65%. This will quickly segway into renewed concerns on Monday. Winds appear to be slightly weaker, even as temperatures and humidity forecasts remain fairly steady. This limits confidence in coverage and magnitude of main concerns. For now, believe northern 204 and wester 206/208 will be the areas to watch for Monday with 20 mph winds or weaker elsewhere.
