Area Forecast Discussion

.SHORT TERM...(Today and tonight)
Issued at 354 AM CDT Tue Aug 22 2017

A cold front has passed through the area overnight, and skies
have mostly cleared in its wake. Winds will remain northerly
through the day today as high pressure builds into the area. This
should limit high temperatures to the upper 70s to mid 80s today.

With the surface high moving overhead tonight, skies should
remain clear and winds will become variable before shifting
southerly into early Wednesday morning. Lows should dip into the
low to mid 50s, and I wouldn`t be surprised if a few spots even
make it into the 40s! Dry air should preclude fog development
despite relatively light winds and clear skies.

.LONG TERM...(Wednesday through Monday)
Issued at 354 AM CDT Tue Aug 22 2017

Main concern will be chances for rain over a period mainly between
Thursday and Sunday.

Synoptic pattern includes a shortwave ridge that will keep us dry
for Wednesday within zonal flow, but behind this ridge, flow
becomes more northwest as an amplifying large-ridge develops over
the Great Basin. This will allow multiple waves of energy, and
subsequent height falls to give us more chances of rain/storms.
Severe weather does not appear to be likely for the long term

By Thursday, with the combination of higher CAPE/steeper lapse
rates and veering south/southeast winds, we could have some
afternoon development mostly to the west that may creep into our
area by late afternoon/evening. Any storms that develop may be
enhanced or maintained by a developing 30-40kt low-level jet
Thursday evening. Lapse rates decrease significantly this far
east, so I would expect any storms to be non-severe as they make
their way into our neck of the woods.

We will then have multiple chances of showers/t-storms through
the weekend as we remain within northwest flow, making us
vulnerable to multiple pieces of energy that may come down the
pike. Temperatures will generally be near normal or lag a bit
below normal in this pattern, with highs generally in the lower to
mid 80s and lows in the upper 50s to lower 60s for the entire
long term forecast.


.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Wednesday)
Issued at 1202 PM CDT Tue Aug 22 2017

VFR conditions should prevail through the forecast period. High
pressure over Neb will help keep skies clear and winds light
tonight. Winds are expected to pick up just a bit by mid morning
Wed as the high pressure drops into eastern KS.
