.SHORT TERM...(Today and tonight)
Issued at 305 AM CDT Thu Mar 14 2019
Not too difficult to pick out the feature of interest in the
satellite imagery early this morning. A tightly wound, stacked
upper level low pressure system continues to slide ENE across
the Central Plains...and is currently spinning over the far
eastern portions of our CWA...on its way into east-central NE by
around sunrise. Am impressed with how consistent the models were
over the past several days in the grand scheme of things with this
system, and did pretty well with the location of this smaller
band that is currently set up through central portions of NE. At
the sfc, the accompanying cold front has made the swing through
all but a very small corner of the SErn CWA. To this point, the
strongest winds have been just outside the western edge of the
CWA, but still have had a number of 55-60 MPH gusts (Ord has been
the highest so far, just gusted to 62 MPH at 243 AM). Looks like
the sfc low was around 977mb or so when it entered the SWrn corner
earlier this evening. Have had reports of reduced visibility and
hazardous travel conditions, and a handful of automated sites have
dropped down to 1/4-1/2 mi...feel headlines are in good shape as
is. Hydrology-wise, have many reports of flooded rivers,
water-covered roadways, etc...there were even a few water-rescues
in Buffalo County.
The forecast for today/tonight will continue to be dominated by
the gradually departing storm system. The worst conditions are
expected to continue through roughly the late morning hours, hi-
res models showing a marked downward trend in precip with time
from west to east. At this point, won't be making any changes to
current headlines...with the Blizzard Warning running through 18Z
and the Winter Weather Advisory for far eastern counties (that may
see at least light snow longer into the day) into this evening.
That Winter Weather Advisory may be running a bit long, but will
let day shift assess trends and adjust as necessary. No change in
the expectations for winds, those stronger gusts just off to the
west are expected to slide into our CWA. Through 18Z, the Blizzard
Warning covers the high wind, with a High Wind Warning in effect
for the remainder of the CWA. Once the Blizzard Warning expires,
the High Wind Warning will return for that area...running through
10 PM this evening.
Thinking is that precipitation will come to an end by this
evening, and kept the 00-12Z period tonight dry. Expecting to
see decreasing cloud cover with time through tonight, and though
winds won't be as strong as what is ongoing currently, they will
still be on the gusty side. Following highs today in the mid 30s-
near 40 (admittedly, confidence in that is on the low side),
overnight lows tonight drop into the lower-mid 20s.
.LONG TERM...(Friday through Wednesday)
Issued at 305 AM CDT Thu Mar 14 2019
With ongoing weather, did not spend a lot of time concentrating on
the long term period.
In the wake of this departing system, models are in good agreement
showing northwesterly flow setting up across the region as we get
into Friday and the upcoming weekend. The forecast for this period
is a dry one, and certainly looks to have more in the way in the
sunshine. NW winds may still be on the breezy side through the
morning hours on Friday, but the overall trend will continue
downward. Speeds closer to 10 MPH are expected for Sat/Sun. Also
have a warming trend in temps in the forecast, with highs in the
upper 30s/mid 40s Friday and up into the upper 40s to mid 50s by
Sunday.
Looking ahead to Monday through Wednesday, outside of a small
chance for precip thanks to a passing shortwave disturbance on
Tuesday, the forecast remains a dry one. 40s and 50s look to stick
around for highs.

.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Friday)
Issued at 1221 AM CDT Thu Mar 14 2019
Powerful storm system will continue to drive the weather at both
terminal sites. Sub-1000ft ceilings and lower visibilities will
continue...with rain finally starting to give way to the snow.
Gusts upstream of the terminals have reached near 60MPH, expect
the same as that front pushes further east. It doesn't look to be
until later this afternoon when snow ends and winds show a
noticeable downward trend, though they will still be plenty
gusty.
