Short term (this evening through Wednesday)
issued at 336 pm cdt Tue may 21 2019
satellite imagery showing a well defined low pressure system
moving into southwestern ks, which has kept the CWA dreary and
damp all day long. Outside of the clearing just starting to creep
into far southern areas, skies across the CWA have been overcast
with sub- 1000ft low level stratus. At the surface, the main low
currently is over swrn ks... With the increased pressure gradient
to its north adding to the unpleasantness of today, with gusty
easterly winds. Gusts at times have been in the 35-45 mph range.

Hasn't been any big surprises with temps, 3 pm ranging from mid
40s to mid 50s. A reminder of how cool we are, the record cool
high for today in grand island is 48 (at 3pm it was 47), for
hastings it's 52 (at 3 pm it was 47).

The rest of this afternoon and into tonight, main driver will
continue to be this upper level low. Models remain in good
agreement showing it continuing on its northeastward trek,
taking it and its accompanying surface low right through the heart
of the cwa. As has been mentioned the past couple of days, there
continues to be a concern of low-topped supercells as that
activity pushes in. While there's not a ton of instability,
there's a sufficient amount, and along with better lower level
shear pushing north... Along with the concern for hail, isolated
tornadoes can't be ruled out. Activity will continue to push north
with time, and have pops ending by 12z Wednesday, but not 100
percent confident in that... A few models a tiny bit of lingering
precip in the 12-15z period.

Outside of that precip concern early in the morning tomorrow, the
rest of the daytime hours are expected to give us a chance to dry
out. Will see more in the way of sun, but thinking at least the
northern half of the CWA will stay partly cloudy through the day.

As the sfc low pushes off to our northeast tonight, winds turn
west- northwesterly for tomorrow, and look to remain on the gusty
side... Especially across the northern half of the cwa. Expecting
an improvement in temperatures, with forecast highs in the lower
60s in the NW to near 70 in the sw.

Long term (Wednesday night through Tuesday)
issued at 336 pm cdt Tue may 21 2019
this mid-week break in the precip is a short-lived one... And while
upper level shortwave ridging keeps things dry for most of the cwa
Wednesday night, some small precip chances works their way back
into the south early Thursday morning. Actually lowered pops for
that 06- 12z period, as some models show things staying dry, but
had inherited pops and with at least a few models still supporting
that, didn't want to completely remove them. Models show another
broad upper level low pressure system becoming better established
over the western CONUS Wed wed night, with lift ramping up across
the area for thurs Thursday night. Pops increase from south to
north through the daytime hours on Thursday, with the late
afternoon-evening hours currently showing the best potential for
widespread precip (aided by an increasing southerly llj)... As a
sfc warm frontal boundary pushes north. The southeastern 2 3rds of
the CWA is currently included in the SPC day 3 marginal & slight
risk outlooks. Models suggest the best instability axis may set up
barely outside our cwa, with high amounts of deep layer shear.

This will be the next day to keep an eye on. Expecting another day
with breezy east winds north of the front, with current forecast
highs not a lot different than Wednesday's 60s low 70s.

Expecting to see another break in the activity for Friday, but the
overall active pattern looks to keep on going through the weekend
and into next week. Hard to have a high amount of confidence in
the timing or exact location of these periodic disturbances
expected to pass through... But will be keeping an eye on severe
weather potential as we get closer. At least fri-mon are forecast
to remain closer to normal for temps, with highs in the 70s lower
80s.

Aviation (for the 18z kgri kear tafs through 18z Wednesday)
issued at 1222 pm cdt Tue may 21 2019
certainly less than ideal conditions will continue at both
terminal sites through the rest of the day, thanks to an upper
level low pressure system finally swinging through the region.

Expecting low level stratus (<1000ft) to continue into this
evening before gradually lifting, shower storm chances linger,
along with gusty east winds. This evening, there is some
uncertainty with timing of a change in winds, as they will
diminish in speed and vary in direction with the passage of the
main sfc low... Before swinging to the west for the remainder of
the period.

Gid watches warnings advisories
Ne... None.

Ks... Flash flood watch until 7 pm cdt this evening for ksz019.

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.
