Area Forecast Discussion
National Weather Service Hastings NE
514 AM CDT Wed Mar 21 2018

.SHORT TERM...(Today and tonight)
Issued at 456 AM CDT Wed Mar 21 2018

Fog channels on satellite reveal an expanding area of dense fog
this morning near I-80 and expanding to much of the area to the
north. The area of dense fog is quite irregularly shaped and
morphing rather unpredictably, so be ready for quickly changing
visibility this morning and icy spots forming from freezing fog
freezing onto contact of surfaces.

Fog should burn of by mid to late morning, but I did lower the
highs today by a couple degrees as we will get off to a bit of a
slower start at warming because of the fog and subsequent stratus
that was produced from it. Also, a strip of larger scale stratus
still hanging on in the far eastern CWA that should finally give
way this morning. Still should be a rather mild day with plenty
of sun and highs in the upper 50s to lower 60s thanks to upper
level ridging building in and a surface warm front tries its best
to move north.

The warm front should make it just north of the CWA tonight, and
will give us quite mild lows in the 30s to around 40.

.LONG TERM...(Thursday through Tuesday)
Issued at 456 AM CDT Wed Mar 21 2018

Upper level ridging will continue and will make Thursday even
milder with highs in the mid 60s to lower 70s, and with rather
relatively light wind, should feel like the warmest day of the
week for much of the CWA.

The surface front sags south a bit for Friday, which will give us
quite a temperature spread from upper 50s/near 60 north to near 80
far south in north central Kansas. Still enough instability to
keep thunder in the forecast for Friday afternoon into the evening
for much of the CWA.

Highs over the weekend will be back into the 50s for most behind
the upper ridge trough axis, but still seasonably mild, behind the
mean upper trough axis and within southwest flow aloft. Seasonable
temps in the 50s thereafter are forecast into next week.


.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Thursday)
Issued at 1256 AM CDT Wed Mar 21 2018

Biggest issue will be dealing with visibility issues as wind has
become light/calm with the surface ridge moving in, and a good
amount of radiational cooling will take place with clear/mostly
clear skies. Tough call as visibility may fluctuate a bit, so went
sort of middle of road MVFR forecast, except a TEMPO group of IFR
at KEAR for the first four hours of the forecast as the
observation showed a brief 2SM. LLWS could be an issue for
Wednesday night, but probably at the very end and even after the
scope of this forecast.


NE...Dense Fog Advisory until 10 AM CDT this morning for NEZ039>041-
