.AVIATION...

Thunderstorms could affect KCNM and KPEQ through 28/01Z, but
probability is too low to include.  Otherwise, VFR conditions
will prevail at all southeast New Mexico and west Texas terminals
during the next 24 hours.

.PREV DISCUSSION... /ISSUED 216 PM CDT MON JUL 27 2015/

There`s been little change in forecast reasoning with models
continuing to support a transitory substropical ridge over the
next few days, i.e., INVOF OK today-Wed and in the 4 Corners
region Fri/Sat. Convection in this pattern will again be mostly
favored in mtns/adjacent plains, but noticing some subtlies like
secondary mid level theta-e ridge axes and theta-e gradients may
help placement of PoPs. Today we expect an uptick in the mtns from
yesterday where theta-e gradient is in alignment with mtns, a few
high based showers are briefly possible across the PB and PoPs
will trend down Tue-Thu. We`re still keying in on the cooling
trend seen in the 1000-500mb thickness and 7h temps. Recently 7h
temps have been around 14C on 00Z MAF sounding with deterministic
model consensus that 7h temps will decrease to around 11C by
00Z/Fri which would yield high temps about 4-6 degrees cooler than
yesterday/today for most areas by Thur PM. There`s a better chance
of precip across the PB Sat/Sun with the NW position of the ridge,
even seen on DGEX. Subtropical ridge will attempt to move back ewd
late in the forecast which would start temps trending back up.
