Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

258 PM CDT Tue Apr 12 2022

...New FIRE WEATHER...

.SHORT TERM...
(This evening through Wednesday)
Issued at 222 PM CDT Tue Apr 12 2022

As of 2:30 PM...the dryline was situated roughly along and east
of line from Stamford to San Angelo to Junction line. Scattered
showers and thunderstorms have developed east of the dryline
across our eastern counties. A severe thunderstorm warning has
already been issued on the storm currently in northern Coleman
County. Given the current environment- ML CAPE values of
2000-2500 J/KG and mid level lapse rates of 8 degrees C/KM per
current RAP analysis- additional strong to severe thunderstorms
are possible through the afternoon and evening hours for the far
eastern Concho Valley and Heartland. The bulk of the activity
should exit our county warning area by around 6-7 PM. For tonight
will hold on to a slight chance of PoPs across our far
southeastern counties as a Pacific front moves down into the area.
Otherwise, lows will fall into the upper 50s to mid 60s.

Wednesday will be much cooler compared to today behind the
Pacific front. Highs will be in the upper 70s and 80s. The
combination of very dry conditions (relative humidity values under
10%) and gusty west- northwest winds will lead to another day of
critical fire weather conditions across the entire area.

&&

.LONG TERM...
(Wednesday night through next Monday)
Issued at 210 PM CDT Tue Apr 12 2022

Southerly return flow will build back in on Thursday, which should
allow high temperatures to climb back into the upper 80s and low 90s
by the end of the week. Otherwise, dry weather will persist. Over
the weekend, there are some model differences, as the GFS shows a
cold front coming down into Texas on Saturday, the ECMWF delays this
front until Sunday. High temperatures could range from the mid 70s
to the low 90s over the weekend, but for now, we trended with the
warmer solution, given the dry soil conditions and overall warm
pattern. Regardless, this could include some rain chances for our
southeast counties over the weekend, but models are still struggling
to get a handle on timing and location.

&&

.AVIATION...
(18Z TAFS)
Issued at 134 PM CDT Tue Apr 12 2022

Scattered showers and thunderstorms have developed this afternoon
east of KSJT. Confidence is low on if these storms will impact any
of our eastern terminals- mainly KABI, KBBD, and KJCT. Will
continue to monitor radar trends closely and amend the TAFS as
necessary. Otherwise, gusty westerly winds will continue this
afternoon before coming down overnight. Westerly winds will become
gusty again tomorrow afternoon behind a cold front.

&&

.FIRE WEATHER...
Issued at 258 PM CDT Tue Apr 12 2022

A Red Flag Warning remains in effect through this evening for
the Big Country, Concho Valley, and the Northern Edwards
Plateau. Gusty southwest winds combined with minimum relative
humidity values 7-18 percent are resulting in critical fire
weather conditions.

A Fire Weather Watch remains in effect for all of west central
Texas for Wednesday. After passage of a Pacific front early in
the day, gusty west to northwest winds combined with relative
humidity falling below 10 percent will result in critical fire
weather conditions. Wind speeds are expected to be 15-25 mph with
higher gusts.

Elevated fire weather conditions are expected to continue through
the rest of the week, during the afternoon hours. Warm and above
normal temperatures will be combined with relative humidity values
dropping to 6-12 percent Thursday, and 10-30 percent Friday.
Winds will be from the south to southeast on Thursday, and mostly
from the south on Friday. Overall wind speeds will be lower than
what is occurring in the first half of this week.
