.SHORT TERM...
(Today through Monday)
Issued at 303 AM CDT Sun Jun 1 2025

The MCS feature that has been discussed is a bit ahead of schedule
this morning. It is currently dropping through OK on its way into
TX. This is not the immediate feature that will affect our area but
the extention to the east will late today as the old stalled front
begins to pivot northward. It will be where the frontal axis is
located that will have the best chance of rain, albeit low. This is
also in a NW flow regime, so any storms that are capable of getting
started, will have the potential to become strong or even severe.
Chances for any storms today will be late in the day and more likely
toward evening. We should be able to keep precip numbers low Monday
a well but the heat and humidity will be back.

&&

.LONG TERM...
(Monday night through Saturday)
Issued at 303 AM CDT Sun Jun 1 2025

Another cold front will be moving SE by mid week, but this one looks
to stall before getting here. It will help intensify the onshore
flow and bring back a more normal distribution of sh/ts to the area
starting around mid week. A basic summer pattern looks to take hold
the remainder of the week.

&&

.AVIATION...
(12Z TAFS)
Issued at 303 AM CDT Sun Jun 1 2025

VFR through this cycle. There is an slight chance of any terminal
getting a temporary TSRA that could drop levels to IFR but not
enough to show in current taf set.

&&

.MARINE...
Issued at 303 AM CDT Sun Jun 1 2025

The stalled front will move back to the north slowly this morning.
Light onshore flow will develop once again as this occurs today and
slowly rise to 10-15kt by mid week. Not many storms are expected
over marine waters especially open gulf waters but those that do
develop could become strong or even severe.
