Issued at 910 PM CST Thu Feb 4 2021 A forecast update is in place for slightly warmer temperatures overnight using the short term model blend plus bias correction. Increasing cloudiness is underway and this should promote mixing and allow surface winds to stay up. The modest surface winds and increase in cloud cover should limit radiational cooling. && .SHORT TERM...(This evening through Friday night) Issued at 259 PM CST Thu Feb 4 2021 The primary forecast challenge centers on temperatures and the threat for multiple periods of light snow through early next week. Period begins with highly amplified flow as troughing that brought us rain and snow overnight this morning quickly departs to the east and mid-level ridging develops across the West Coast. A small plume of drier air has worked into the area this afternoon which has helped lead to dry conditions and clearing skies across much of the region. Areas of cumulus are bubbling over the higher terrain over western South Dakota through western Kansas. This is occurring in an area of modest mid-level lapse rates and should diminish with loss of daytime heating. Within the northwest mid-level flow will be a couple pulses of energy. While moisture should increase slightly off the surface, lift will remain weak. As a result, opted to remove the flurries/light snow mention for the morning hours across the Sandhills. Have overnight lows tonight falling into the teens and low 20s across the area. High pressure will push a backdoor cool front through the area during the day Friday. This will put a large temperature gradient across the area with highs approaching the mid 40s for our far southwest zones while only reaching the mid 20s near the Missouri River under partly to mostly cloudy skies across the area. Heading into Friday evening, isentropic lift on the 285k surface will increase as a weak surface low develops across southeast Wyoming into northeast Colorado. Modest troughing aloft will move through the area heading into early Saturday morning, leading to increased forcing for ascent by way of warm-air advection and fgen in the h85-h7 layer. This will lead to the area's first real potential for accumulating snow. The GFS has been the biggest proponent of this potential with a fairly impressive band of frontogenesis passing through the area in the 00z-15z timeframe Saturday. With precise QPF forecast in question, it's worth mentioning the consensus between the NAM and GFS regarding potential for liquid precipitation amounts to approach a quarter inch or higher while the Euro lags behind. The current forecast more closely aligns with the Euro solution, which limits amounts to around 0.15" or less. W.r.t. ensemble guidance, this lines up with the EPS as well but falls short of of the GEFS and SREF mean values. Individual SREF members show tight clustering in two pockets...one around 0.05" and one around 0.2". Given the magnitude of forcing advertised by the NAM and GFS, I do believe this forecast is a bit conservative but will leave to subsequent forecasts to adjust should guidance hone in on higher or lower amounts after coordination with neighboring offices. Given this, thinking snow amounts will peak around 1-2" of light, fluffy snow, but this could increase with later forecasts. Highs Saturday will fall across the board, with values in the low teens across north central Nebraska to the low 30s in the far southwest. Precipitation will end Saturday afternoon as fgen wanes and the trough axis clears the area to the east. .LONG TERM...(Saturday through Thursday) Issued at 259 PM CST Thu Feb 4 2021 Beginning 00z Sunday. Period begins with northwest flow aloft following the passage of the trough axis. The region will still reside under the northern stream jet, and with that a few disturbances will push through the area Sunday into Monday. The first will pass through Saturday evening into Sunday morning. NWP output is in fairly good agreement with a developing a northwest to southeast oriented snowband across the Sandhills into central Nebraska. This is largely tied to strong warm-air advection in the vicinity of a weak warm front, coincident with weak mid-level vorticity advection. Biggest question with respect to this round of snow will be southward extent as moisture availability rapidly decreases with southward extent. Utilizing the model blend has increased PoPs slight with the introduction of the "Likely" category across north central Nebraska. This lines up with a blend of the EPS, GEFS, and SREF output but may be hedging a bit north of what the deterministics solutions suggest. At this time, will leave PoPs as they are as any changes would be minimal. Forcing for ascent will rapidly diminish through the late morning on Sunday, therefore this narrow band will quickly subside by midday. Initial thoughts are for QPF in the a few hundredths on the fringes of the stronger forcing to perhaps around a quarter of an inch underneath the frontogenetical band. This would easily translate to upwards of 2-3" of snow given the magnitude of cold air in place...highs ranging from the low 30s in the far southwest to the single digits across north central Nebraska. A second quick moving disturbance will approach from the west late Sunday into Monday. This system will likely have better upper-level support across the local area but more limited moisture. This shows up as greater discrepancies between the EPS and GEFS on probabilities of 1" or greater snow with the EPS only advertising 30% while the GEFS shows probabilities as high as 60%. This is likely due to the GFS being much stronger with the mid-level wave and quicker with the approach of the upper-level jet. It is also further north with the warm front. Either way, confidence in this second round is much lower therefore the forecast is subject to change until NWP guidance hones in on a better consensus. As high pressure builds in once again towards the middle of the week, expect to see temperatures well below normal and likely limited to single digits to low 20s northeast to southwest each day Monday through Thursday. Additional chances for precipitation will exist Tuesday through Thursday, however, no one disturbance appears to be overly significant so expect just low-end PoPs with light to perhaps moderate snow at best. Regarding the expected cold temperatures...with h85 temperatures approaching anomalies of -10 to -20 degrees C through Valentine's Day, expecting morning lows to fall near or below zero each morning. Given air temperatures that cool, any wind the develops in the morning will drive wind chill values into the negative teens and potentially as low as the negative 20s, which would be wind chill advisory criteria. Given general high pressure in place, limiting factor each morning would be winds and how strong they manage to get. At this time, not seeing any glaring signal of strong winds any particular morning therefore any confidence of reaching criteria at this time is fairly modest. Regardless, with air temperatures falling below zero, prolonged exposure to these temperatures will be enough to lead to issues therefore will plan to keep hitting the messaging hard regarding this threat. && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 1122 PM CST Thu Feb 4 2021 Areas of MVFR in isolated to scattered -SHSN and low ceilings will spread through nrn Nebraska 10z-18z Friday.

At this time, snow accumulations are expected to be fairly light, however, this could change as we head into the weekend. Much colder temperatures are expected this weekend into next week as the area will see its coldest temperatures so far this winter season. Wind chills Monday morning, Tuesday morning and Wednesday morning, will range from 10 below zero to as much as 25 below zero. .SPOTTER INFORMATION STATEMENT...
