Short term (this evening through Thursday night)
issued at 321 pm cdt Wed may 22 2019
the low pressure system that was over nebraska yesterday has slowly
continued its track north northeastward into the great lakes region
giving us a short break from precipitation. On its heels a
disturbance moves in from the southwest with another chance of
showers and thunderstorms returning Thursday afternoon and evening.

For the short term forecast there are two main forecast challenges,
first one being the potential for frost tonight. Cooler temperatures
will continue to intrude the northwest sandhills once again,
hovering just above freezing. Have decided to hold off on issuing
a frost advisory as there is moderate confidence that although
temperatures will be chilly and near freezing there won't be the
radiational cooling needed to get widespread frost. Several models
indicate although there may be some breaks in the clouds and
clearing towards evenings, but low to mid level clouds will build
back in after midnight across the northern sandhills with the
approaching disturbance.

As for thunderstorms on Thursday, have put in chances for showers
and thunderstorms starting in the early to mid afternoon. That
being said confidence is low in shower and thunderstorm
development that early, models have not been in great consensus
with the timing and feel that the system may be a few hours behind
as the previous system was slightly slower to move out of the
area. Forecast confidence increase in showers and thunderstorm
development for the evening hours and added increased pops for the
forecast area. At this time severe thunderstorm potential appears
to be low as the best environment for severe thunderstorms will be
farther east and south of western and southwest nebraska, but an
isolated strong thunderstorm can't be ruled mainly east of
highway 83 as there is a marginally favorable environment.

Long term (Friday through Wednesday)
issued at 321 pm cdt Wed may 22 2019
high pressure will continue to sit across the southeast CONUS with
several disturbances coming in across the pacific coast into the
high plains through the long term forecast period.

More showers and thunderstorms are possible over the latter half
of the memorial day weekend on Sunday late afternoon and evening
and Monday afternoon and evening. There are some discrepancies in
the placement of shower and thunderstorm development for Sunday
and Monday. A few models move the system slightly quicker
northward on Monday, with less certainty for storm Monday
afternoon and evening, will need to continue to monitor in
upcoming forecast.

Temperatures will warm to near normal Friday through Sunday with
highs mostly in the 70s. Temperatures will cool to slightly below
normal Monday through wed. With highs in the 60s to low 70s.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 1222 pm cdt Wed may 22 2019
MVFR ceilings are forecast to remain across north central
nebraska including the kvtn terminal this afternoon. Elsewhere
vfr conditions this afternoon. MVFR to ifr ceilings to redevelop
across the panhandle and northwest sandhills after 06z tonight,
which should remain west of the kvtn terminal Thursday morning.

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.
