628 AM CDT Sun Jul 23 2017

.SHORT TERM...(Today and tonight)
Issued at 256 AM CDT Sun Jul 23 2017

After an extended period of extreme heat/humidity, temperatures
will be slightly cooler today...closer to the mid-July normals...
near 90-95F degrees. While still hot, heat indices will stay in
check with a little drier air. Skies will be mostly clear and
winds will be light transitioning from northerly to southeasterly
through the day/evening. Tonight it will be quiet with lows in
the 60s.

.LONG TERM...(Monday through Saturday)
Issued at 256 AM CDT Sun Jul 23 2017

Aloft: The Westerlies will be fairly zonal along the US-Can border
Mon-Tue...but a small low will be advancing E across Srn Canada.
Heights will begin to fall over the NE Pac resulting in downstream
amplification Wed-Sat...with a ridge/subtropical high evolving over
the Wrn USA and a trof in the E.

Spaghetti plots of the last 2 runs of GFS/EC are tightly clustered
with each other and their respective ensemble means.

Surface: Nrn Plns high pres will build into the Cntrl Plns Sun and
then gradually slip to the E Mon-Tue. The trof moving across Canada
will drive a cool front across the Nrn 2/3 of the CONUS. Return flow
will develop here Mon with the front arriving Wed. The front will
cont sinking S into the Srn Plns Thu-Fri...with Nrn Plns high pres
building in.

Sensible wx details...

Rain: Typical of summer...chances are very very low thru Tue...and
any limited tstm activity will be very spotty. There is very little
to force tstm development...except on the smaller end of the
mesoscale...and predictability with such small features is
impossible beyond day 1. Most places will cont dry.

The best chance for sct tstms will be Wed over S-cntrl Neb and Thu
over N-cntrl KS. Svr tstms will be possible given the magnitude of
the instability...but shear will be limited.

Temps: averaging a little above normal (low-mid 90s by day and 60s
to near 70 at night).


.AVIATION...(For the 12Z KGRI/KEAR TAFS through 12Z Monday)
Issued at 628 AM CDT Sun Jul 23 2017

Weak winds have allowed temperatures to drop and some light fog is
possible this morning at both terminals. Do not expect less than
MVFR conditions with 4-6sm visibilities. VFR conditions expected
beyond 15Z with light northerly winds becoming easterly and
eventually southeasterly through the day/night.
