A vorticity maxima, embedded within a broader closed upper low along the Great Divide, rotated out across the Southern High Plains on the 8th. Widespread showers and thunderstorms produced locally heavy rainfall across portions of the area that, combined with heavy rains during prior days, led to a few reports of urban and stream flooding across the region.

.NEAR TERM...
(Rest of today and tonight)
Issued at 244 PM CST Thu Nov 7 2024
A nearly stationary upper low near the Arizona/New Mexico border is
still expected to move slowly eastward tonight into Friday. The low
is then forecast to lift north and northeast across the Panhandles
and far western Kansas Friday afternoon into Saturday. Deep
isentropic ascent in advance of this system, is resulting in an
increase in cloud cover and scattered showers and thunderstorms.
A few strong to severe thunderstorms have developed across northern
Texas this morning and afternoon. Elevated instability across
western north Texas and far southern Oklahoma per RAP soundings is
around 500-750 J/kg with deep cloud layer shear over 60 kts.
Therefore, a few strong to severe will remain possible through the
afternoon and into at least evening.
Overnight, surface low pressure is expected to become better
developed across West Texas in response to the approaching low. This
will help maintain a northeast to east flow across much of Oklahoma
and western north Texas. This will also aid in advecting higher
dewpoint air northward into at least our western north Texas
counties. At this time, it appears better boundary layer moisture
will remain mainly south of our Texas counties, so any strong to
severe storms will mainly pose a risk of hail and or wind.

.SHORT TERM...
(Friday through Saturday night)
Issued at 244 PM CST Thu Nov 7 2024
It still appears the main story with this event will be areas of
excessive rainfall, starting Thursday evening and continuing through
at least Friday evening. Record to near-record PW values, and a
rather deep warm cloud layer will result in rather efficient
rainfall rates/amounts. Storm total rainfall amounts are expected
to be in the 2 to 4 inch range, especially across the western
half/third of Oklahoma and northern Texas. However, there is
roughly a 30-40 percent probability of rainfall amounts exceeding
5 inches, especially across parts of southwestern Oklahoma and
northern Texas. More localized amounts of 6 inches are also
possible. With any heavy rain event, still some uncertainty with
how far north and east the heaviest rain will occur. Plan to add a
few more counties to the east of the current Flood Watch.
Most of the rainfall is expected to move east of I-35 by mid evening
Friday and mainly confined to eastern Oklahoma after midnight.
Cooler and drier weather will prevail Saturday.
&&
.LONG TERM...
(Sunday through next Wednesday)
Issued at 244 PM CST Thu Nov 7 2024
Overall no changes were made to the long term period. There is some
potential for a freeze by early Thursday morning of next week. If
this occurs, it should mainly impact parts of western and northern
Oklahoma.
Issued at 245 AM CST Thu Nov 7 2024
The period looks to feature mostly dry surface conditions and nil
weather impacts. Quasi-zonal flow looks to emerge across the Plains
into the early week, with a slow warming trend expected. Some
locations across western-north Texas have a medium (40-60%) chance
to see 80-degree high temperatures on Tuesday. By the midweek,
attention will turn towards the potential for the passage of another
high-amplitude upper system across the central CONUS. At this
update, some precipitation potential and arrival of a frontal
passage (cooler temperatures) are advertised. Details on this system
will come into better focus into this weekend.
