AREA FORECAST DISCUSSION National Weather Service Hastings NE 1236 PM CDT Mon Apr 27 2020 .SHORT TERM...(Today through Tuesday night) Issued at 545 AM CDT Mon Apr 27 2020 Starting off with some highlights for the entire 7-day forecast: 1) Precipitation-wise, the majority of the next week is looking relatively dry. The only official chances for measurable rain are currently late tonight into Tues AM, and then not until the weekend. Both of these time frames carry their own uncertainties, but at this point odds seem decent that most of our coverage area (CWA) will fail to measure more than one-quarter inch of total weekly precipitation (higher exceptions possible of course in thunderstorms). 2) Temperature-wise, this next week (as a whole) will average quite warm for late-April/early-May, on the order of 10 degrees above! This means plenty of highs in the 70s/80s and lows mainly well into the 40s/50s (maybe even a few 90s in southwestern zones for Friday?). As a result, there is essentially zero concern for freezing temps through at least the next week, and frost appears quite unlikely as well (unless Wed night trends several degrees colder). 3) From a hazardous weather perspective, unless we end up being surprised late tonight/Tues AM by a rogue feisty storm, we will most likely get through the entire month of April without issuing a single convective warning (this is fairly uncommon)! As for storm chances next weekend (early May be then), it's still way too early to put much stock in the details, but very early indications suggest some stronger storms may be possible. 4) Fire weather remains a legitimate concern for especially Tues/Wed afternoons given low RH/fairly strong north-northwest winds. Please refer to the separate Fire Weather section below for any further discussion of this topic. Taking a look at the current/recent weather scene as of 430 AM: No big surprises overnight, as our rain/thunderstorm coverage sure enough ended up being VERY limited (as was largely expected). The main swath of weak thunderstorm activity (long since ended) tracked across portions of our KS zones, where a few tiny rain showers are actually still bubbling up every now and then. Meanwhile, the vast majority of our Nebraska area remained dry, as convection instead fired slightly to our east within the nose/exit region of the low level jet, and marched eastward from there. On the larger scale, this activity was driven by a low-amplitude wave sliding through the prevailing west-northwest flow aloft. At the surface overnight, gusty southerly winds last evening have eased quite a bit as a weak trough axis (not a true cold front) has slipped into the area, with most places currently reporting a southwesterly breeze around 10 MPH or less. Temp-wise, lows are on track to hold up a solid 10-15 degrees above yesterday, with most places bottoming out somewhere in the 47-54 range. Now focusing solely on these first 48 hours in the remainder of this Short Term section, the main stories are: 1) By many folk's definition, today will be an absolutely spectacular spring day (sunny/very warm/light wind), with widespread highs in the low-mid 80s. 2) Very late tonight into Tues AM there will be a chance for passing showers, fairly weak thunderstorms. However, as has been the case for the past several days, there remains uncertainty regarding this activity will be on the spotty or more widespread side. Although have at least a basic "slight chance" all areas, current model consensus favors fairly sparse coverage (perhaps slightly better north/east of the Tri Cities?). 3) Although still quite mild temp-wise, Tuesday will be a completely different animal in the wind department, with fairly strong north-northwest winds gusting well into the 30-40 MPH range. Also, while not really reflected in our official forecast yet, there are increasing signs that Tues afternoon may soon require some chances for passing rain showers/weak storms (for now have at least introduced sprinkle potential). Now going into more detail on these first 48 hrs/4 periods... Today: As mentioned, today will simply be a very enjoyable/very warm weather day in the opinion of most. Once the last of the pesky/very light showers depart our KS zones in the next 1-2 hours, the entire CWA is all but guaranteed a dry, warm and very sunny day, with in fact very minimal cloud cover whatsoever, as we reside "in between" disturbances aloft. At the surface, enjoy today's light winds because days like this are relatively rare in the spring! Although not dead calm (of course), speeds most of today will average only 5-10 MPH with even gusts mainly under 15 MPH. Direction will be somewhat variable, but generally undergoing a gradual transition from westerly, to northerly to easterly for most areas as the trough axis/weak front essentially "washes out" over us. As for high temps, although most models/guidance suggest we may be "overdoing it" slightly, made very little change to the warmer values that previous forecaster put in, as the mild start and full sunshine should result in widespread highs mainly in the 81-85 range. This evening/tonight: High confidence in a continued dry forecast through at least midnight, with only a gradual increase in southerly breezes this evening ahead of the next/stronger disturbance approaching from the west-northwest. Then, late in the night into early Tuesday morning, chances for at least spotty showers/storms enter the picture as forcing increases aloft and a surface cold front sweeps in. Unfortunately, models continue to show some disparity regarding the ultimate coverage/likelihood of this activity, with the latest ECMWF pretty much completely dry, while the NAM is a bit more generous with coverage, especially in our northeast zones. No matter how much (or more likely how little) happens, severe storm concerns are quite minimal given the expectation of no more than a few hundred J/KG of elevated instability. However, small hail or even some gusty winds cannot be ruled out. Given the fairly widepsread clouds and steady breezes, lows tonight will be 5+ degrees warmer than those this morning, with most places aimed well up into the 53-58 range. Tuesday daytime: Already by sunrise, northwest winds will be picking up in our far northwest, with these stronger winds then slated to quickly overspread the rest of the area by mid-late morning. In general, expect several hours of sustained speeds 15-25 MPH/frequent gusts 30-40 MPH, more than enough to drive the fire weather concerns covered below. Precipitation-wise, lingered small chances for showers/weak storms in far east-southeast zones for the morning, but most areas should be dry by then (if they ever see anything in the first place). The bigger question mark is whether the combo of colder air aloft and deep mixing along the southern periphery of a reinforcing shortwave trough dropping in from the north-northwest will promote at least isolated to perhaps scattered showers/weak storms during the heating of the afternoon/early evening. Over the past 24 hours, various models (ECMWF/NAM/GFS) seem to be showing this scenario as increasingly-likely. In our official forecast, we have not really "ramped up" to this scenario quite yet, but at least to get the ball rolling this direction, have introduced a basic "slight chance of sprinkles" to much of the CWA to at least imply that the afternoon may not be truly dry. However, would look for PoPs/rain chances to increase somewhat in later forecasts. Temp-wise, highs only look to drop off about 5-8 degrees from today's values, with most areas still well into the mid 70s to around 80. Tuesday night: At least for now, this is advertised as a dry-but-breezy night, although per previous paragraph later forecasts may need to linger some rain shower activity into at least the first part of the evening (mainly before 10 PM). Otherwise, fairly high confidence in a dry late-night period, as we reside under sharp north- northwesterly flow aloft on the backside of a deepening mid level low expected to be centered over IA/MO by sunrise Wednesday. Although not quite as strong as the daytime winds due to shallower mixing, the pressure gradient along will keep gusts solidly 20-30 MPH going all through the night. These winds will obviously keep temps from dropping off too far, but lows should still end up roughly 10 degrees cooler than tonight simply due to a cooler airmass, with most areas mid-upper 40s. .LONG TERM...(Wednesday through Sunday) Issued at 545 AM CDT Mon Apr 27 2020 General overview of this 5-day period: The main story is that this time frame starts out pretty much guaranteed dry for at least Wed-Fri as broad/expansive upper level ridging moves in from the west and overspreads the Plains. The main question is then how long this dry stretch lasts? Per the preferred ECMWF solution, we could easily remain dry until Saturday night. However, the GFS is a slightly faster to break down/flatten the ridging, with rain chances perhaps returning as early as early Saturday morning/daytime. Overall though, model consensus points to halfway decent shower/thunderstorm chances centered around Saturday night, with early suggestions of at least some strong (maybe not necessarily severe?) activity. Again though, the main message is that at least "some" chance for rain returns over the weekend, with plenty of details to iron out. Temperature-wise, although averaging out solidly-above normal as a whole, there does look to be a minor roller-coaster ride, with highs starting out only around 70 degrees most areas Wednesday (this has been trending cooler), but then soaring well into the mid-upper 80s by Friday as the intensity of the upper ridge peaks (maybe even some low 90s southwest!). Then, as the ridge breaks down and a surface cold front goes through, we are very preliminarily calling for highs well back down into the 70s by Sunday. As for lows, most nights well above normal in the 40s/50s with zero freeze concerns. However, Wed night is gradually trending a bit colder given the expectation of light winds. We currently still have most areas holding up into the low 40s, but especially favored colder spots (such as Ord) could perhaps end up trending toward the mid-30s as this gets closer in time, which could bring a touch of patchy frost into play for a few spots (something to watch). Otherwise, one other item of note is that Wednesday will feature another round of fairly strong north-northwest winds, with near- critical to perhaps critical fire weather in play (see below for more). && .AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Tuesday) Issued at 1231 PM CDT Mon Apr 27 2020 VFR conditions expected through the period, but there are a couple things to keep an eye on in this forecast. 1.) Isolated showers thunderstorms early Tuesday morning, especially 09-12Z. Confidence is not high enough for anything other than a VCTS mention at this point. 2.) Frontal passage Tuesday morning. This will impact the TAF sites 12-14Z, causing winds to shift to the northwest, with gusts of 25kts in the morning...likely followed by 30kt+ gusts in the afternoon. 3.) Additional showers/thunderstorms Tuesday afternoon. This is just outside of the TAF window for now, but confidence is increasing in at least a few showers/storms again in the afternoon. && .FIRE WEATHER... Issued at 545 AM CDT Mon Apr 27 2020 At least near-critical conditions are likely within particularly western/southwestern portions of the CWA each afternoon Tuesday- Thursday, with Tues/Wed currently carrying the greatest concern for potentially outright-critical conditions due to fairly strong north-northwest winds. While winds will be quite gusty area-wide, at least for now, only a handful of southwestern counties (mainly southwest of an Elwood-Osborne KS line) are technically expected to reach afternoon relative humidity (RH) values of 20 percent or lower (our critical criteria), and thus promoting possible/eventual Warning issuance. This would all seem fairly straightforward if not for the fact that much of the area is at least into the beginning stages of spring green-up, with vegetation/grasses gradually becoming less prone to widespread fire growth. As a result, there is currently some uncertainty with our "fuel status" regarding whether Warnings may actually be warranted. Our current game-plan is to hopefully communicate with local fire weather partners during the next 24 hours and get a better handle on whether vegetation/grasses are "yes/no" for potential Warning issuance for Tues-Wed afternoons. No matter whether we end up with Warnings or not, the bottom line is that at least solidly-near-critical conditions will exist, especially in our far southwestern counties.

Very late tonight into early Tuesday morning, a few thunderstorms are possible almost anywhere in the outlook area, but with the overall-best chances favoring areas north and east of the Nebraska Tri Cities. Severe storms are not expected, but a few instances of small hail and gusty winds cannot be ruled out. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. Each afternoon between Tuesday and Thursday, the combination of low relative humidity and gusty winds will promote at least near- critical fire weather conditions across much of the outlook area. Tuesday and Wednesday carry the overall-greatest concern due to featuring the strongest winds, with critical conditions possible for areas mainly southwest of a line from Elwood Nebraska to Osborne Kansas. From Saturday into Sunday, thunderstorm chances return to various portions of the outlook area, .SPOTTER INFORMATION STATEMENT... Spotter activation should not be needed through tonight. && More information may be obtained at the following web page: https://www.weather.gov/hastings Pfannkuch
