Issued at 0234 AM CDT WED AUG 26 2015

Currently in between a strong amplitude upper level ridge centered
over the central and southern Rockies, and a strong area of low
pressure north of the Great Lakes, within strong north-northwest
flow. We remain under control of high pressure in the lower levels
which is keeping a cooler and drier air mass over the region. We
have already broken a record low for the morning at Vichy and have
the potential to still do so at West Plains. (See climate section
below). Clouds are scarce this morning, but there are a few upper
level clouds streaming northwest to southeast via the stronger
upper level northwest flow.

The forecast will mainly focus on the temperatures in the near and
short term, with low end chances of rain late in the week into
early weekend.


.SHORT TERM...(Today and Tonight)
Issued at 0234 AM CDT WED AUG 26 2015

Looks very similar today as we had yesterday, with upper level
northwest flow remaining in place and low level high pressure.
This will keep the cooler and drier air mass in place over the
region through the short term. Highs today will be similar to
yesterdays readings, which will be below normals for this time of

.LONG TERM...(Thursday through Tuesday)
Issued at 0234 AM CDT WED AUG 26 2015

Shortwave energy will begin to break down the upper level ridge a
bit on Thursday and this energy Will begin to drift east-
southeast into the forecast area Thursday night into Friday.
Moisture will take some time to increase across the area and am
not expecting much in the way of precipitation until we get into
late Friday into Friday night and a cold front and main upper wave
begin to push into the area. Even then, precipitation looks to be
scattered throughout the area through Saturday.

The main shortwave should push off to the southeast by Sunday with
upper level ridging building in from the southwest to round out
the weekend into early next week. Precipitation chances during
this time frame look to be very low. Temperatures should trend
more towards normal as well.


.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
Issued at 0109 PM CDT WED AUG 26 2015

VFR conditions are expected over the next 24 hours. Will need to
monitor the potential for a few showers or storms Thursday morning
across eastern Kansas that may approach the JLN aerodrome.
Confidence is much too low at this time to include in the
forecast, but trends due bear watching. Light/variable winds will
give way to a southeast breeze on Thursday.
