.SHORT TERM...
(This evening through Wednesday night)
Issued at 337 PM CDT Mon May 20 2024

An upper level ridge is currently centered over central Mexico just
southwest of Brownsville Texas. The axis of this high currently
extends northeastward to the southern periphery of the Great Lakes.
It will suppress southward the next couple days as an upper level
trough currently moving through the Rockies tracks northeastward
across the Northern Plains. More locally, this will bring higher
500mb heights overhead as the ridge axis becomes draped right across
the CWA. This will keep rain chances out of the forecast and
maintain temperatures well above normal with highs and lows well
into summer category.

.LONG TERM...
(Thursday through Sunday night)
Issued at 337 PM CDT Mon May 20 2024

Like the near-term, really not much to talk about in the extended
portion of the forecast. High pressure will maintain hot and
rainless conditions. Temperatures will creep up a few degrees from
today which may approach records in some locations. At the moment,
it doesn`t appear that dewpoints will be high enough to support heat
indicies anywhere near heat advisory, but should at least exceed 100
late this week.

The ridge will continue to be suppressed southward as another trough
tracks across the mid Mississippi River Valley this weekend. That`ll
eventually allow for some afternoon convection but currently doesn`t
look like that`ll happen until sometime next week.

.AVIATION...
(18Z TAFS)
Issued at 337 PM CDT Mon May 20 2024

Clear skies and light winds through the period will lead to no
appreciable impacts for most terminals. A few such as KMCB, KBTR, and
KASD may see MVFR visibilities tomorrow morning as light fog will be
possible. Otherwise, VFR will dominate the forecast.

.MARINE...
Issued at 337 PM CDT Mon May 20 2024

A fairly benign period of weather is expected over the coastal
waters through the end of the week as a broad ridge of high pressure
dominates the region. A persistent southeasterly wind of around 10
knots and relatively calm seas of 1 to 3 feet are expected through
the end of the week. The high pressure system over the area will
also keep thunderstorm development at bay, so no waterspout,
lightning, or localized gusty winds are anticipated through Friday.
Overall, a great week for boating activities is on tap.
