Area Forecast Discussion
National Weather Service Hastings NE
701 PM CDT Thu Jul 6 2017

.SHORT TERM...(This evening through Friday)
Issued at 223 PM CDT Thu Jul 6 2017

Forecast concerns include small chances for tstms in the next 24 hrs
along with extent of cooling for Friday.

Current water vapor imagery along with 12Z upper air analysis shows
a high amplitude ridge over the western half of the country with the
high centered near the four corners region. Looks to be broad
troughing in the east with the low/trough that has lingered to our
southeast the past several days now phasing in with the northern
trough. This puts our area in N to NW mid/upper flow as evidenced by
MCS overnight that dove south and affected our northern CWA before
weakening. 15Z surface analysis had low pressure extending from NW
Minnesota to the SW part of the Neb panhandle. Decent pressure rises
of 2 mb per 3 hr behind the trough/front should help it slowly push
south today and tonight. Update...front has continued south with
wind shift line from NE to SW Neb, including north winds at ODX
where temp had climbed to 101 at 2 pm CDT.

First concern involves tstm chances late this afternoon into the
evening. Not seeing much in the way of forcing in the mid/upper
levels, although we do have the weak cold front sagging into the
CWA from the north. Instability shouldn't be an issue as ML CAPE
values are progged to be in excess of 1500 J/KG ahead of the front
while 0- 6 km bulk shear should be in the 25-30 kt range. But in
addition to the lack of a strong forcing mechanism, we are also
expecting some mid level capping with 700 mb temps in the 12-13C
range be mid/late afternoon. Moisture also lacking a bit. As is
often the case this time of the year, the question boils down to
will there be enough heating at the surface to overcome the cap.
If we do get anything to pop, a few storms could be strong/severe
with damaging winds the primary threat as forecast soundings
showing inverted V configuration. HRRR has been consistent today
showing isolated tstms over the Neb part of our CWA. Given this
and the fact it hasn't taken much the past week to get spotty
storms, will leave slight chc going.

Several models including the HRRR and NAM nest keep precip chances
going during the daytime on Friday which seems reasonable with a
weak mid level disturbance passing through. Temps should be
around 10 degrees cooler with the cold front expected to be south
of the CWA. Precip chances look to be the best for the SW CWA
Friday night with MCS progged.

.LONG TERM...(Friday night through Thursday)
Issued at 223 PM CDT Thu Jul 6 2017

Don't see much change in the overall pattern into the weekend as
the upper ridge is progged to remain over the Rockies with
troughing to our east. Cannot rule out weak shortwaves moving into
our area on northwest flow, but timing these more than a day out
is difficult. This is a typical pattern for this time of year.
Seasonal highs in the upper 80s/lower 90s with 20 percent chances
of afternoon/overnight tstms.

For the early to middle part of the workweek, an upper trough may
move into the northwest part of the U.S. which could dampen the
ridge and push it east and over us. Precip chances do not look as
promising depending on how warm we get in the mid levels of the
atmosphere. With the ridge overhead, temps should hot, with
mid/upper 90s expected, with some sites in our KS CWA hitting the
century mark.

.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Friday)
Issued at 634 PM CDT Thu Jul 6 2017

VFR conditions are expected to continue throughout the TAF valid
period. The chance for thunderstorms is present tonight, but very
low and thus not included in the TAF. Thunderstorms this evening
will likely end up southwest of our KEAR and KGRI TAF sites. Best
chance, although still small of catching a shower or thunderstorm
at our TAF sites will likely be Friday morning but still too low
to include in this TAF. The wind direction will remain light and
variable tonight.
