.AVIATION...00Z TAFs...Isolated to scattered showers and
thunderstorms have formed along a broken line from Clayton to Boise
City, with southeast motion possibly taking them towards KDHT & KGUY.
Have added thunderstorm mention to KDHT from 24/01Z to 24/03Z to
address ongoing convection headed towards the location, and will
monitor KGUY as coverage over the OK Panhandle is more sparse.
Otherwise, southerly winds should taper off after sunset as pressure
gradients weaken to AOB 12 kts before increasing once more Sunday
aftn. Northwesterly flow aloft will bring more favorable chances for
thunderstorms at KDHT & KGUY Sunday aftn, which are addressed with
PROB30 AFT 24/21Z. Southerly winds will also increase AFT 24/18Z to
around 10 to 20 kts.



.PREV DISCUSSION... /Issued 325 PM CDT SAT JUL 23 2016/

Upper high over the Panhandles today will shift westward over the
Great Basin region and southwest states through the middle and end
of next week. Another upper high over the Gulf coast states and the
Gulf of Mexico will allow for weakness in the upper flow across the
Panhandles. Northwest flow by the middle and end of next week will
allow for shortwave troughs to track east and south out of the
central Rockies and across the central Plains states and Panhandles.
The chances for convection will increase late this weekend through
the end of next week mainly during the afternoon and evening hours.
The hot conditions with temperatures at or above 100 degrees will
come to an end as the heights decrease and high temperatures fall
back into the 90s. A surface trough is expected to develop across
eastern New Mexico. A stationary frontal boundary across eastern
Colorado and southern Kansas through early next week should lift back
to the north and east as a warm front by Tuesday or Wednesday before
moving back to the south and west again and then stalling across
eastern Colorado and southern Kansas by late next week.
