Area Forecast Discussion
National Weather Service Hastings NE
358 AM CDT WED JUL 13 2016

...Multiple Chances for Hit-or-Miss Tstms thru Sat then Turning
Dry and Very Hot Next Week with a Multi-Day Stretch of Excessive
Heat looking Probable...

.SHORT TERM...(Today and tonight)
Issued at 358 AM CDT Wed Jul 13 2016

Aloft: The Westerlies were zonal over the Nrn USA with a slight
cyclonic bend. There was an embedded weak shortwave trof from WA
southeast to CO. This trof will move over the Nrn Plains today and
combine with another trof dropping S out of the Canadian Prairies.
The combined trof will move into the Wrn Great Lakes tonight. The
passage of this trof will shift winds aloft slightly from W to
WNW.

Surface: Features are weak and very difficult to identify. The
two most identifiable features were a deep occluded low along the
Manitoba/Ontario border and high pres over the W Atlantic. There
was no observational evidence that the cool front that moved thru
Mon exists. A new cool front was forming over over the Dakota's
into WY. This front will surge SE crossing the fcst area today.
Nrn Rockies high pres will begin building in tonight.

Fcst confidence is very low in rain chances/POPs. There is no
strong forcing and because of that the models are highly diverse
in their outcomes. Looking at SREF and EC ensemble QPF
probabilities for .10" over the next 24 hrs (12Z/Wed-12Z/Thu)...
the best chance for tstms will be over SE Neb and NE KS east
across IA/MO into the Srn Great Lakes.

Today: The on-going MCS over NW KS is a major fcst complication
...in addition to the sct shwrs/tstms developing around and ahead
of it. The NAM/NMM/ARW have the best handle on this and trends
suggest continued ESE/SE movement. While expect most of the
intense tstm activity to remain just S of the fcst area...Rooks/
Osborne/Mitchell counties are in Svr Tstm Watch #376 until 15Z.

Expect a steady light rain to fall S of Hwy 6 this morning...
associated with anvil blow-off.

There could be a few random tstms also develop early (before
noon) along the approaching cool front from the N.

The expansive cloud shield associated with the MCS will suppress
temp rise this morning.

Tstm development this afternoon/eve should primarily be focused E
of the fcst area (SE Neb/NE KS/IA and MO)...where a low-lvl jet
will be directed. However...there could be a couple isolated
storms develop along the front and/or whatever little activity
develops this morning could intensify. This is predicated on
decreasing clouds and destabilization in the wake of the morning
MCS.

The 03Z SREF does an excellent job depicting decreased instability
associated with the MCS...but it does indicate recovery. With
temps in the upr 80s-low 90s and dwpts 65-70F...MLCAPE is fcst to
be 2000-3500 J/kg with the highest values over N-cntrl KS. 0-6 km
shear will be 35-40 kts. This environment will support organized
multi-cell and supercell storm structures..."if" tstms develop at
all. There's no guarantee. But if anything fires...it is likely to
be severe.

Large hail and damaging winds will be the primary threats.

Tonight: any early evening tstm activity should quickly exit E and
S of the fcst area by 10 pm. However...increasing/strengthening
upslope flow behind the front should initiate tstms over Ern CO
and Wrn Neb/KS. Some of this activity could move in well after
midnight. MUCAPE of 1500-2500 J/kg will remain with deep layer
shear more than supportive of strong/organized updrafts.

.LONG TERM...(Thursday through Tuesday)
Issued at 358 AM CDT Wed Jul 13 2016

Overview...There will be a welcomed break in the heat Thursday
through Saturday when high temperatures will be several degrees
below normal, generally in the lower to mid 80s. The heat will
begin to return to the region on Sunday especially across Kansas,
and then will build into the rest of the forecast area as we head
into early next week. High temperatures by next Tuesday are
expected to range from the mid 90s to around 100. Once the heat
arrives next week, the long range forecast models really show it
sticking around for numerous days. There will be at least some
chance of isolated to scattered thunderstorms every day from
Thursday through Saturday night due to the more southerly track of
the upper level jet stream. This will all change by around
Sunday/Monday as the jet stream heads north and a substantial
upper high develops overhead resulting in what will likely be a
very hot and dry period next week and possibly beyond.

Thursday through Saturday...More temperate below normal
temperatures will dominate. The jet stream will be nearly overhead
with weak short waves passing through bringing at least some
chance for thunderstorms. The best chances for precipitation will
be during the evening and overnight hours with the possibility of
elevated thunderstorms. The sfc winds on at least Thursday and
Friday will be somewhat easterly, which supports the cooler
temperatures and will give us that chance for elevated convection
depending on how the low level jet sets up. Confidence in timing
and location of precipitation chances is fairly low due to
widespread model variations and only very subtle features to
initiate thunderstorms.

Sunday through Tuesday...As mentioned in the overview section a
large upper high will begin to build across the region. This will
dry things out and heat us up. However, the most significant heat
may not arrive until just beyond the end of this forecast period
around the middle to end of next week and possibly persist well
beyond that. Confidence in the pattern shift back to dry and hot
is high.

.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Wednesday)
Issued at 1242 AM CDT Wed Jul 13 2016

Significant Weather: potential for MVFR fog 10Z-13Z Today. Weak
cold frontal passage around 15Z.

Rest of tonight: Scattered patches of 15-25K ft VFR clouds...but
MVFR fog is possible after 09Z. Light SE winds generally 10 kts or
less becoming S. Confidence: Medium

Wed: MVFR fog dissipates by 13Z. Then VFR with scattered patches
of 15-25K ft clouds. S winds under 10 kts will shift to NW after
FROPA...then to N or NNE. Confidence: Medium

Wed eve: VFR. N-NE winds under 10 kts. Confidence: High
