All is quiet on the aviation front this morning. Cirrus is
clearing out across NE LA but moisture in the 6-10kft level is
funneling in to our northwest with the presence of a shortwave
that will traverse across our region today. Some patchy fog was
also noted north and west of the I-30 corridor this morning but it
appears that this fog should stay to the north and west of our
terminals this morning. Expect mostly light and variable winds
today becoming calm this evening. Otherwise...VFR conditions
should prevail through the next 24 hours.
.PREV DISCUSSION... /issued 433 AM CDT Thu Oct 27 2016/
Upper level short wave continues to shift away from the region
this morning per latest water vapor imagery as upper ridge over
the Rockies begins to expand eastward. Any linger showers across
the LA/MS delta region will continue to diminish this morning.
Expect a gradual warming trend over the coming days as the ridge
becomes firmly entrenched across the southern CONUS. Highs today
in the lower to mid 80s will tick up a few more degrees on Friday
and through the weekend with upper 80s becoming more likely for
our southern zones. Overnight temperatures will also continue to
warm back near 60 degrees after the past several mornings in the
50s this week.
The ridge axis will begin to shift east of the region by early
next week and signal the start of a changing upper level pattern.
An upper trough will move onshore along the CA coast Tuesday and
quickly pivot eastward across the desert southwest and into the
southern Rockies by mid week. This trough will begin to draw on
increasing Gulf and Pacific moisture as it moves into the southern
Plains by next Thursday. This pattern will at least provide for a
slight increase in rain chances as early as Tuesday but even more
so during the late week timeframe with a cold front expected to
dive south with the upper trough by the end of next week. Expect
temperatures to dip closer to seasonal averages during the mid to
late week timeframe in response to the increasing cloud cover and
uptick in rain chances as the upper trough transitions eastward.
