.PREV DISCUSSION... /issued 310 PM CDT Sun Jul 1 2018/

DISCUSSION...

WV imagery shows a large upper trough moving thru the Rockies,
trailing a weak cold front that sfc analysis and radar shows has
made it almost to KMAF.  This does not seem to be having much effect
on afternoon temps, which look to top out a few degrees above-normal
later this afternoon.  Weak SW flow ahead of the front and mixing
have brought dewpoints down considerably from this morning, shunting
best moisture to the NE.  This is yielding sbcapes in excess of
3000J/kg over the Permian Basin and areas north, making this area
behind the front probably our best chances for convection this
afternoon and overnight.  Forecast soundings suggest steep mid-lvl
lapse rates of around 7C/km and a dry subcloud layer will pose a
marginal hail/wind threat, but shear will be rather anemic, so we'll
just mention this in the HWO.

Overnight, the trough quickly minors out over the Great Lakes
region, allowing the upper ridge over the Gulf Coast states to begin
building back west.  This will shift chances of convection in the
short term to the higher terrain of West Texas and Southeast New
Mexico.  Thru midweek, the ridge is forecast to meander not only
west but north as well, centering over the Central Plains and
bringing cooler, easterly flow under the ridge into this area.  All
models are in pretty good agreement in bringing thicknesses/temps
down below-normal by Thu afternoon.  Temps then AOB normal thru the
extended.  Near the end of the workweek, long-range models bring an
inverted trough thru south Texas in easterly flow, which could
enhance rain prospects, especially south.  By the weekend, the ridge
is forecast to be over the Four Corners region, maintaining easterly
upslope flow and slight chances of convection each day.  However, no
real triggers are advertised.  Blended POPs seem a bit high, and
model differences suggest toning things down a bit.
