Area Forecast Discussion
National Weather Service Shreveport LA
112 AM CDT Mon Jun 14 2021

.AVIATION...

For the 14/06Z TAF period, all sites are VFR to begin the period
and this should continue through the next 24 hours. The possible
exception is some brief reduction to vsbys with active convection
in East Texas early this morning and any patchy fog that develops
closer to daybreak. Otherwise, expect cumulus to linger through
much of the period with cirrus above that as a weakening frontal
boundary struggles to make additional southward progress into the
region. Therefore, winds will generally remain light and variable
overnight before gradually trending more E/NE if the front manages
to push farther south.

.PREV DISCUSSION... /issued 1026 PM CDT Sun Jun 13 2021/

UPDATE...

This evening update is twofold: an update to overnight lows, and
adjustments to PoPs. Afternoon highs rather exceeded expectations,
as such it will take longer to reach overnight lows. Those have
been bumped up as well. As for PoPs, a line of thunderstorms are
following outflow boundaries east to west, and will quickly outrun
the previously established PoPs. They have been adjusted to
account for these thunderstorms.

PREV DISCUSSION... /issued 253 PM CDT Sun Jun 13 2021/

SHORT TERM.../Tonight through Monday Night/

For the rest of today...While the chance is fairly low, isolated
showers and thunderstorms will be possible this afternoon, with
the best chances coming for areas along and southeast of a line
from Lufkin, TX to Ringold, LA to near El Dorado, AR. Should
showers and thunderstorms move into this area, there is a threat a
few of them could become strong to severe at times. Already seeing
an uptick of thunderstorms firing across southwest Arkansas and
northwest Louisiana. Meanwhile, satellite imagery from this
afternoon continues to show an increase in cu across the entire
area. In addition, afternoon heat indices could reach the lower
to mid 100s, so continue to use caution if outdoors for an
extended period of time.

Upper-level ridge will continue to control the southwest CONUS
through the short term period and beyond. We could see additional
showers and thunderstorms across the area into the early overnight
hours as the passing backdoor cold front could struggle to clear
the area. Overnight lows will range from the lower to mid 70s once
again across the area. On Monday, additional afternoon showers
and thunderstorms will once again be possible across our far
southern and southwest zones as the remnant frontal boundary
lingers. High temperatures on Monday will once again climb into
the lower to mid 90s across the area with afternoon heat indices
reaching the upper 90s to lower 100s across the area. Monday night
will be slightly "cooler" across our northern zones with lows
falling into the upper 60s, with lower 70s expected elsewhere.

This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, east Texas and northeast Texas.

.DAY ONE...This Afternoon and Tonight...

Scattered showers and thunderstorms are expected to develop by mid
and late afternoon across Northcentral Louisiana and Lower East
Texas, and spread west southwest across these areas during the
evening in advance of an approaching upper level disturbance.
Given the extent of instability that has developed, some of these
storms may be strong to severe, with damaging winds and brief
heavy rainfall possible. These storms should gradually diminish late
tonight with reduced instability. In addition, afternoon
temperatures will climb into the lower to mid 90s across much of the
region. When combined with the humidity, heat indices will range
from 101 to 105 degrees, with some locations briefly exceeding 105
degrees.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

Isolated to widely scattered showers and thunderstorms will be
possible Monday afternoon and evening over the southern sections
of Northcentral Louisiana and Deep East Texas, before mostly dry
conditions return Tuesday through much of the coming work week.
Moisture should begin to increase by Saturday to support the
return of at least isolated showers and thunderstorms for next
weekend.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters may be needed this afternoon and
evening.
