...New AVIATION...

.SHORT TERM...
(Today through Sunday)
Issued at 350 AM CDT SAT JUL 20 2024

This AM, a stationary surface front is stretched from SW to NE
from SW LA to NE MS across portions of NRN AL and NEWD to E KY.
This boundary will nudge a bit further to the N this morning
leaving C AL on the warm/moist side of the front. In the upper
levels, there is a tight low over ERN Canada. However, the
gradient is rather loose over the ERN US as the base of the trough
turns a bit more SW TWD TX with ridging pinching in from the WRN
Atlantic and weak onshore flow on the Gulf Coast near the base of
the trough and weak flow over FL. In the lower levels, we have a
moist SRLY fetch to feed any perturbation interactions moving
around the upper trough base. Look for continued waves of
convection. Overall onshore flow increases further for Sunday.
Temperatures may be a degree or so warmer today in spots, but are
overall similar with little changes expected for Sunday...off and
on rain waves and repeat.

.LONG TERM...
(Sunday night through next Friday)
Issued at 341 AM CDT SAT JUL 20 2024

Very little change is expected in the overall pattern for much of
the upcoming week. The persistent trough through the Central US will
remain in place leading to at least some upper level forcing and
moisture transport across the region. This will lead to slightly
more active diurnal thunderstorm activity each day Monday through
Friday. High temperatures will be moderated somewhat, limited to the
80s to low 90s each day depending on exact timing and placement of
thunderstorms.
