Below-normal temperatures with a medium (30-60%) chance of showers on Tuesday. - Near-normal temperatures on Wednesday and Thursday with a low (10-20%) chance of showers and thunderstorms on Thursday. - A gradual warming trend by the end of this week into this weekend with dry weather expected. && .DISCUSSION... Issued at 1205 PM CDT Mon Apr 27 2026 After an active period of weather last week and weekend, a much quieter weather pattern in taking shape for this week. A cold front moved across the region this morning, ushering in cooler temperatures. A few lingering showers and thunderstorms are quickly exiting the region to the east early this afternoon. Gusty northwest winds remain behind the cold front into this evening. Temperatures have already reached their highs for the day as temperatures are holding steady or falling behind the front. Tuesday will start cold as 30s are likely for the area. There is a low (10-20%) chance of frost across portions of northeast Nebraska where temperatures fall to near-freezing. That said, lingering winds and relatively warm ground temperatures should keep frost at bay. Despite surface high pressure building across the Great Plains, a chance of showers returns by Tuesday afternoon as a mid-level disturbance moves overhead. While there is a medium (30-60%) chance for rain across the area, dry air near the surface will greatly limit what actually reaches the ground. Temperatures should be well below normal with highs in the 50s due to continued cloud cover and rain chances. Once again, temperatures fall into the 30s for most by Wednesday morning. Temperatures return to near normal by Wednesday afternoon and Thursday afternoon with largely zonal mid-level flow taking shape over the region. Highs in the 60s with lows in the 30s and 40s are to be expected. There is at least a low (10-20%) chance of showers and perhaps a thunderstorm on Thursday with another passing mid-level disturbance. That said, limited moisture should limit what actually reaches the ground. By the end of this week into this weekend, a warming trend begins. This is supported by a upper-level ridge building across the western third of the country. Temperatures climb into the 70s to near 80 through this period. Dry weather is anticipated at this time, with sunny skies forecast through this weekend. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 636 PM CDT Mon Apr 27 2026 MVFR ceilings prevail across the area this evening with widespread stratus at FL020. Expect to see cigs lift just after midnight tonight as breezy northwesterly winds continue to slow. Tuesday brings a chance of showers (30-40%) to the area mid- day. Gave a large window of possible shower activity in the afternoon tomorrow at KOFK and KLNK and left KOMA dry for now due to lower confidence. Expect any shower activity to be spotty and occasional. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && $$ DISCUSSION...Chehak AVIATION...Nicolaisen

059 FXUS63 KGID 272249 AFDGID Area Forecast Discussion National Weather Service Hastings NE 549 PM CDT Mon Apr 27 2026 .KEY MESSAGES... - Starting very late tonight, and continuing through Thursday night, there will be intermittent chances for light showers and perhaps a few WEAK thunderstorms (chances for severe storms through at least the next 7 days appear almost non- existent). - Frost and/or slightly sub-freezing temperatures will come into play for at least portions (potentially most?) of our forecast area (CWA), especially late Tues night-Wed AM and then again Thurs night-Fri AM and Fri night-Sat AM. Still a little uncertainty on temps, so no formal Advisories/Warnings out just yet. - Precipitation-wise beyond Thursday night: Fairly high confidence that at least Fri-Sat remain dry (possibly Sun-Mon too, but not as "certain"). The bottom line: Take what rain you can get through Thursday night. - Temperature-wise: a stretch of somewhat-cool weather for late April/early May, especially through Friday (highs mainly 50s-low 60s/overnight lows mainly low 30s-low 40s). Sat-Mon then brings a modest warm-up...but still a far cry from "hot" with highs mainly 70s/lows mainly 40s. - On a positive note: For the first in at least weeks, there are NO apparent heightened/critical "fire weather days" through at least the next week (due in part to the cooler temperatures), although perhaps some "near-critical" conditions could sneak back into play by Sun-Mon. && .DISCUSSION... Issued at 437 PM CDT Mon Apr 27 2026 -- FORECAST CHANGES OF NOTE/BIG PICTURE COMMENTS: - No truly "major" changes of note from previous forecast issued early this AM. - As already alluded to in the Key Messages above, we are actually in the midst of a fairly "ideal" weather pattern for the next several days: seasonably-cool with intermittent rain chances and NO higher-end fire weather setups OR chances for severe storms. The only folks who might complain are the "warm weather lovers", as no days with 80+ degree highs will occur anytime soon. -- 7-DAY FORECAST CHRONOLOGICAL RUNDOWN (through Mon. May 4): - CURRENT/RECENT WEATHER SCENE AS OF 33O PM: First, a quick recap of rainfall over the last 48 hours: Back on Thursday, this forecaster mentioned that MOST of our CWA would hopefully pick up at least 0.50-1.00". Fortunately, MOST places in fact did. However, as always there were lower exceptions on either side. On the low end, a few western and also southeastern counties (particularly much of Dawson/Gosper/Nuckolls/Clay/Thayer) fell solidly short of 0.50...but at least mostly picked up at least 0.25". On the higher end of things, a stripe running very roughly from west of Hastings to north of Aurora picked up at least 1.50" (localized 3"), while parts of several of our KS counties also saw at least 1.50-2.00". All in all, decent totals, but it sure would have been nice if EVERYBODY had gotten at least 0.50". On to the here and now: The last of the spotty showers/weak thunderstorms from the weekend system either dissipated over/departed east of our forecast area (CWA) several hours ago now, with this afternoon featuring dry conditions under skies ranging from cloudy/mostly cloudy across roughly the northeastern 2/3rds of our CWA, to partly cloudy (even pockets of mostly sunny) within our southwestern 1/3rd. Its been breezy to somewhat-windy area wide, with sustained northwesterly speeds commonly 15-25 MPH/gusts 25-35 MPH. High temperatures are on track to range from upper 40s-low 50s far north-northeast, to a mix of mid-upper 50s across most of our Nebraska counties, to low-mid 60s mainly in our KS counties along with Furnas County area. In the big picture of the mid-upper levels, water vapor satellite and short-term model data clearly show us "in between" disturbances, with the departing one exiting over IA/MO, while the next main shortwave trough is working its way through the CA/NV/AZ border area...with weaker "ripples" extending out ahead of it into the Central Rockies. - THIS EVENING-OVERNIGHT: Fairly high confidence that our entire CWA makes it through at least midnight dry, as breezy winds gradually subside and turn more northerly. Then, between midnight and sunrise Tuesday (but mainly after 3-4 AM), a weak upper wave arriving from the west will generate at least a narrow, generally west-east oriented band of chilly light rain. There is some uncertainty on the "exact" placement of this rain band, and rain chances (PoPs) are likely too broad in north-south extent, but consensus of latest models favors the western half of our Nebraska CWA for the highest chances for at least few hundredths of pre-sunrise rain. Briefly touching on precip type, we are expecting this precipitation to be ALL RAIN within our CWA, but please note that some slushy snow could mix in with the rain not all that far west-northwest of our CWA (out over the Sandhills), so again, this will be a chilly rain. As for temps, am counting on a mix of continued low clouds and then quite a few mid-high clouds arriving from the west (especially post-midnight) to keep things from "tanking" too far...and some places could see lows reached closer to midnight with steady/very slightly rising temps thereafter as clouds/precip arrives. If anything nudged up lows very slightly from previous, aiming most of the CWA between 35-39 degrees. Although this is technically cold enough for at least limited frost development (especially far northwest), the increasing clouds and/or rain moving in should largely prove unfavorable, and we don`t have any frost in the official forecast. - TUESDAY DAYTIME: It`s becoming pretty clear that this will be the overall-coolest and (in various places) overall-wettest daytime of the week. Aloft, the next low amplitude shortwave trough swings directly through the Central Plains, driving continued chances for at least scattered light rain showers especially within our Nebraska counties (lower chances in KS). We`re certainly not talking big amounts (most places no more than 0.05-0.20"), but we`ll take what we can get! A rogue rumble of thunder cannot be ruled out, but with such meager instability have omitted from official forecast. Temperature-wise, if anything nudged down highs very slightly from previous, with most of our CWA (especially Nebraska) aimed 49-54, and the majority of any mid- upper 50s focused in KS. Finally, it will not be as windy as today, with speeds mainly around 10 MPH out of the north to northeast. - TUESDAY EVENING-OVERNIGHT: Right away early in the evening (mainly pre-nightfall) we could still see some lingering light rain showers in our north- northeast zones, and perhaps a few showers sneaking into our far southwestern zones out of southwestern NE. However, high confidence that it`s dry through the night most all areas (especially beyond 10 PM). Winds will only average around 5 MPH or less from a mainly northerly or westerly direction. That leaves cloud cover (and resultant temperatures) as the "million dollar question" that could ultimately make-or-break the development of frost and/or slightly sub-freezing temps. Unfortunately, there is some uncertainty here, but our latest forecast is geared toward "mostly clear skies with patches of lower stratus here or there"). Assuming this plays out, temps should have no problem dropping well into the 31-36 range most places, with areas of frost a decent bet. That being said, IF low stratus remains more stubborn, it could remain a few-to- several degrees warmer. Given these modest uncertainties, refrained from issuing any Frost Advisories and/or Freeze Warnings on this shift, but these will be strongly considered within the next 24 hours. One one final note, we could also perhaps see some patchy fog development, but have kept this out of the official forecast for now. - WEDNESDAY DAYTIME-THURSDAY NIGHT: Aloft, our area will reside under west-northwesterly flow, as a few fairly weak disturbances brush through our area. At the surface, the main feature will be a weak cold front dropping through from the north on Thursday. Precipitation-wise, while most of Wed daytime will remain dry, isolated showers/weak thunderstorms could drift into mainly our northern/western counties late Wed afternoon into Wed night, with additional chances for isolated/scattered activity targeting mainly our southern/southwestern CWA Thursday daytime-evening before rain chances vacate southward late. Temperature-wise, highs both days are fairly similar (mainly low-mid 60s). As for overnight lows, Wed night appears a touch warmer given more clouds and areas of rain, with lows mainly upper 30s-low 40s and thus minimal frost concerns. However, Thurs night-Fri AM looks chillier (lows mainly low-mid 30s) and perhaps more favorable for frost and/or slightly sub-freezing temps. - FRIDAY-SATURDAY: Fairly high confidence in our going dry forecast, as we reside under rather benign north-northwesterly flow aloft (to the west- southwest of a large-scale low centered over the eastern Great Lakes region). Friday looks to be our final "coolish" day with highs low-mid 60s, with Saturday then turning about 10 degrees warmer (mainly low-mid 70s) as breezes turn southerly. One final opportunity for frost development could arise Fri night-Sat AM before the warm-up commences. - SUNDAY-MONDAY: While latest ECMWF/GFS suggests that most of these two days will be dry, they also both show some spotty light shower potential mainly Sunday-Sunday night as an upper wave passes through in the continued north-northwesterly flow aloft (our official forecast currently assigns most of these small rain chances to Sunday night). Temperature-wise, some guidance suggests our forecast could be aiming a touch too warm, but for now we are calling for highs mainly mid 70s both days, with MAYBE our far south-southwestern counties touching 80. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Issued at 548 PM CDT Mon Apr 27 2026 For KGRI/KEAR Airports: Ceilings are expected to hover between VFR and MVFR (2-4kft) through most of the period. Currently VFR ceilings may dip back to MVFR this evening before improving again later tonight. Rain showers move in from the west on Tuesday. A few showers are possible as early as 10Z, but the most likely timeframe is late morning through mid afternoon. Northwest winds decrease tonight and turn to the northeast for Tuesday. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None. KS...None. && $$ DISCUSSION...Pfannkuch AVIATION...Mangels
