...New SHORT TERM, LONG TERM, MARINE...

.SHORT TERM...
(Today through Wednesday night)
Issued at 242 AM CDT Mon May 20 2024

High pressure is over the Atlantic coast this morning which is
providing a light onshore flow locally. Aloft a ridge is building
in from the southwest. This pattern will remain in place during
the short term and provide summer-like temperatures and plentiful
humidity while keeping rain chances virtually nil. Winds may
slightly increase Tuesday and Wednesday as low pressure moves
across the plains.

&&

.LONG TERM...
(Thursday through Monday)
Issued at 242 AM CDT Mon May 20 2024

The ridge breaks down a bit as a frontal bndry stays well north of
the region. However there could be just enough instability/lift for
some isolated showers/storms across the area. Similar pattern
continues into Friday, with highest POPs well north of the area.

Heading into next weekend and early next week, the pattern remains
somewhat zonal across the area. High pressure remains entrenched in
central MX. Uncertainty remains as to how far south any frontal
bndry can get and shower/storm activity.

Daytime highs in the upper 80s Thursday will gradually warm into the
lower and perhaps middle 90s by early next week. These temperatures
will also be dependent on any shower/storm activity.

.AVIATION...
(06Z TAFS)
Issued at 1139 PM CDT Sun May 19 2024

Little change from previous TAF thinking, with just some patchy
fog possible mainly at the southern sites late tonight resulting
in brief MVFR vsby reductions. Otherwise, VFR is expected to
prevail with light to near calm winds tonight becoming S-SE
5-10 KT during the day.

.MARINE...
Issued at 242 AM CDT Mon May 20 2024

Light winds and no precip is anticipated today, however low
pressure will move into the plains during Tuesday. This will
slightly tighten the pressure gradient and increase winds locally
through the remainder of the week. Winds are expected to remain
below SCA criteria.
