Area Forecast Discussion
National Weather Service Shreveport LA
249 PM CDT SAT JUL 23 2016
.DISCUSSION...
Heat index values at this time remaining at or below 110 degrees
across the region. With convection increasing, not expecting heat
index values to climb much higher through the remainder of the
afternoon. An upper-level low across eastern Arkansas to drift
south maintaining a chance for showers and thunderstorms through
the overnight hours. Low temperatures tonight to fall into the mid
to upper 70s.
Heat advisory remains in effect through 7 PM. At this time there
are no plans to extend the heat advisory into Sunday. The upper-
low is forecast to bring mostly cloudy skies and higher rain
coverage on Sunday, limiting high temperatures to the mid 90s
across areas that would have sufficient low-level moisture to
support higher heat index values.
Upper flow to become west to southwest by Monday with a broad
surface low forecast to retrograde westward across the gulf of
Mexico through the middle of the work week. The low is forecast to
open into a broad trough from Texas to the Great Lakes region by
the end of the week. This pattern will allow for scattered to at
times numerous afternoon showers and thunderstorms across the
region through the end of the forecast period. Also, high
temperatures through most of next week to only climb into the low
to mid 90s.
