351 PM CDT MON JUL 25 2016

.SHORT TERM...(This Evening through Wednesday Night)
Issued at 351 PM CDT MON JUL 25 2016

Shower and thunderstorm chances will be good through most of the
short term as the westerly upper level flow early on turns northwest
towards the end of the short term. This flow will continue to bring
one short wave after another over the region. At the surface, a
frontal zone stretched across North Dakota late this afternoon will
make its way slowly south through Tuesday night/early Wednesday. As
this occurs, the warm, moist, and unstable south winds will become
northeast into Wednesday and Wednesday night as Canadian high
pressure pushes in drier and less humid air. Severe weather does not
look to be a great possibility over the next few days as the deep
layer shear does not look good except southwest in the region.
Tuesday looks like another very warm/hot day with highs in the mid
80s to the lower 90s. Wednesday will cool down some as Canadian air
pushes in on northeast winds with highs in the upper 70s to the mid

.LONG TERM...(Thursday through Monday)
Issued at 351 PM CDT MON JUL 25 2016

The upper level long wave pattern will feature low pressure over the
Hudson Bay Region and high pressure over the southwest CONUS. This
leaves the Northern Plains under northwest flow through Friday.
Several shortwaves will influence the region, however models are
pretty conservative on moisture/instability through this time frame.
Very mild temperatures as well, with highs in the low 80s.
The upper level pattern begins to transition for the weekend as the
high pressure ridge slides over the central US. This should result
in a drier and warmer conditions (highs nudging back into the upper
80s and 90s) through the weekend and into early next week.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 1228 PM CDT MON JUL 25 2016

southwest through the afternoon...becoming gusty along and west of
the Missouri River. Gusts up to 30 mph can be expected at the KPIR
TAF site. Scattered thunderstorms are possible later this evening
and overnight.
