As of 230 AM, a broad swath of light to very light rain was
impacting most areas south and east of an Albany to Ozona line.
Rainfall rates with these showers are topping out at a few
hundredths an hour with the highest around 2 tenths of an inch an
hour across far southeastern Mason County. As this rain spreads
north and west, it seems to be losing its strength with radar
returns weakening significantly and most of this rain likely not
reaching the ground. A band of heavier rain is currently moving
through Llano and Gillespie counties and is moving west northwest
towards Kimble and Mason counties. Heavier rainfall rates closer
to 3-4 tenths of an inch per hour can be expected with this but it
is moving fairly quickly so the heavier burst will be short
lived. The overall complex of rain is expected to slowly drift
west/northwest through the morning with the bulk of the activity
out of our area by around 18Z. With our area on the far western
periphery of the upper ridge, some minor upper level impulses may
provide just enough additional lift to create some showers and
storms, especially across the southern half of the area as
abundant moisture will still be in place, along with marginal
instability at around 500-800 J/kg SBCAPE. These are expected to
be more diurnal in nature and are not expected to be severe. They
should gradually dissipate after sunset with the overnight hours
expected to be dry across the area. Daytime highs will remain
cooler in the mid to upper 80s with gusty east winds. Overnight
lows will be about the same as before in the upper 60s to low 70s.

(Friday through Wednesday)
Issued at 316 AM CDT Thu Jun 20 2024

A warming and drying trend will begin on Friday, as high pressure
rebuilds across West Central Texas and warm southerly flow
persists through the middle of next week. Afternoon high
temperatures will start off in the mid 80s to mid 90s on Friday,
increase into the mid 90s to near 100 by the end of the
weekend, then rise into the upper 90s to up to 104 by Wednesday.
Unfortunately, there are no precipitation chances expected
through the long term forecast at this point.

.AVIATION...
(06Z TAFS)
Issued at 1216 AM CDT Thu Jun 20 2024

VFR to IFR conditions currently present across the area right now as
a swath of showers moves in from the southeast. These showers have
had minimal impact on visibility so far with most sites staying
above 6 miles, apart from KJCT where 5 mile visibility looks to
linger through the overnight hours. Ceilings at all sites are
expected to drop further to between MVFR and IFR later overnight.
Our southern sites, KJCT and KSOA, will see gusts out of the east
continue through the overnight hours between 18-25 kts with the
other sites seeing gusts drop off. The rain showers will gradually
move out through the morning hours with all sites returning to
VFR by late morning/early afternoon. There remains a chance for
isolated shower/storm activity during the afternoon but coverage
is still too spotty to include a mention in this package. MVFR
ceilings will return to our southern terminals before 06Z tomorrow
night.
