...New DISCUSSION...
.DISCUSSION...
Issued at 245 PM CDT Fri Jul 14 2023
The rest of the evening through tomorrow...
Showers and storms are expected to continue through the remainder of
the afternoon and potentially linger into the evening. The potential
for severe weather continues this afternoon, but is steadily
decreasing as drier air moves in from the west, decreasing any
significant chance for widespread severe chances. In the along the
Hwy 82 and wast of I-55, there continues to be enough mid/low-level
vorticity along the MCV to generate severe thunderstorms capable of
damaging wind gusts. Additionally, slow storm motions and opposing
corfidi vectors continue to support backbuilding in the northeast.
Due to this, a "Limited" for isolated flash flooding is outlooked
for the remainder of the afternoon into the early evening. Between 1-
3 inches and some locally higher amounts of rain will be possible.
Heat will continue to be an issue for the remainder of the afternoon
into the early evening. Observations are showing heat indices
ranging between 105-110 degrees across the CWA, especially those who
lacked cloud cover this morning. A Heat Advisory remains in effect
until 8 pm tonight.
By this evening into tonight, showers and storms are expected to
linger, mainly in the north. Overnight lows will range in the middle
to upper 70s. On Saturday, ridging will continue to build in from
the west, allowing for heat indices to range between 105-110 once
again. A Heat Advisory is in effect from 10am - 7pm on Saturday.
Rain chances will remain in the northern and eastern portions of the
region tomorrow. Isolated showers and thunderstorms will be
possible. Highs are expected to range from the lower to upper 90s. /AJ/
Saturday night through Monday: Upper troughing will build over the
eastern CONUS to begin the new week. This will bring the corridor of
more active weather further south, with higher rain chances over the
central and southern portion of the forecast area by Sunday. The
trough may shift far enough south for a somewhat drier airmass to
edge into parts of north MS and AR Sunday, and further south into
Monday, though dewpoints are still expected to remain in the 70s.
Areas south of I-20 are more likely to remain in a rather humid
airmass, with heat stress a potential concern outside of
interference from clouds/rain.
Tuesday through next Friday: The upper trough will shift east, with
a building mid/upper high over the Southern Plains becoming the more
dominant feature. Through the middle portion of next week, this
ridge will build eastward toward the Deep South and begin to direct
more of the shortwave-driven convection around our region with
convection becoming more isolated in nature and heat becoming the
main theme. With considerable low level moisture lingering, heat
indices in the 105-110F range will be possible each day and temps
may reach the upper 90s in some areas.
The ridge will begin to retreat later in the week, with rain chances
ramping up again by next Friday as a trough again develops over the
eastern US. /DL/
