SHORT TERM. (Today through Friday) Issued at 323 AM CST Thu Dec 12 2019
Considerable cloud cover exists from the West Coast eastward into Montana and Wyoming. This will bring increasing cloud cover today, especially during the afternoon. Despite the cloud cover, warmer 850mb temperatures reaching 3-5C will result in highs from around 50 across southwest Nebraska, mid and upper 40s central Sandhills, to the mid and upper 30s far northeast. Winds will be light today, but will be southwest this afternoon across the western half of the area.
For tonight, and upper level trough will move across the Dakotas into central and eastern Nebraska after midnight. This will bring a slight chance for light snow to the northeast, including Butte and O'Neill. Lows to range from the mid to upper 20s.
On Friday, another disturbance located over southern Montana into northeast Wyoming will quickly drop southeast into western Nebraska. This will bring a slight chance for light snow to the northwest Sandhills in the morning, with a 20 to 30 percent chance for mainly light rain to most of the area, excluding the far southwest and far eastern areas. This will also bring in a cold front with a corridor of stronger northwest winds expected from the panhandle into southwest Nebraska during the afternoon. Wind gusts to 35 mph are expected favoring the stronger CONSMOS winds. Highs still fairly mild from the lower 40s north to near 50 southwest.
LONG TERM. (Friday night through Wednesday) Issued at 323 AM CST Thu Dec 12 2019
The before mentioned disturbance will continue to track southeast during the evening, with mainly a slight chance for light snow everywhere except the far southwest areas, followed by a slight chance far eastern areas after midnight. Not expecting much for snowfall amounts as a multimodel blend only supports a tenth of an inch snowfall east of Highway 83 overnight.
Forecast models continue to indicate a fairly strong upper trough reaching the coast of Oregon and northern California on Saturday. Ahead of this system fast zonal flow will bring at least a slight chance for light snow mainly west of highway 83 Saturday afternoon. Slight chances continue Saturday night as upper flow becomes more northwesterly and the upper trough moves across Nevada.
Following the track of this system Sunday through Sunday night indicates substantial model differences. The operational GFS tracks the system further north to bring chances for light snow across southwest into central and eastern Nebraska, while the ECMWF and Canadian models both keep the system further south to mainly affect Kansas. The current forecast comes into best agreement with the GFS ensemble to maintain a 30-40 percent chance Sunday/Sunday evening across the southwestern third of the area, to a slight chance northwest Sandhills. Temps will be cold enough for all snow and some travel impacts are possible Saturday into Sunday. Forecast confidence is low with this portion of the extended forecast so some changes in subsequent forecasts are likely.
Monday through Wednesday is expected to be dry as an upper ridge located along the West Coast builds eastward into the Central Plains by Wednesday. Highs from 30 to 35 on Monday should warm up into the lower 40s by Wednesday.
AVIATION. (For the 18Z TAFS through 18Z Friday afternoon) Issued at 1127 AM CST Thu Dec 12 2019
A steady stream of high clouds will continue to track across western and north central Nebraska over the next 24 hours. This will bring broken to overcast skies ranging from 15000 to 20000 FT AGL. Ceilings may lower to 8000 to 12000 FT AGL at the KVTN terminal late tonight into Friday morning as a disturbance approaches northern Nebraska.
LBF WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
