Severe Thunderstorm Warning 195, NWS Shreveport, LA

Area Forecast Discussion
National Weather Service Shreveport LA
251 PM CDT SAT JUN 18 2016

.DISCUSSION...
Line of thunderstorms continuing to march southwest across deep
east Texas this afternoon. Some thunderstorms have produced winds
strong enough to down trees but widespread outflow driven wind
gusts have prevailed across most locations. Severe Thunderstorm
Watch 270 remains in effect but will likely be trimmed back from
the east by the time of the afternoon issuance.

Heat advisory will likely also be cancelled with the afternoon
issuance. Outflow boundary will have moved across all points
within the advisory area at or shortly after issuance time
mitigating the need to maintain it through 7 PM.

Will maintain mention of showers and thunderstorms through
midnight across southern zones due to low-level trough axis still
forecast to linger across the region.

Much cooler temperatures expected Sunday and Monday with highs in
the upper 80s to around 90 each day. Upper-ridge to gradually
build throughout the early part of the week allowing for surface
airmass modification and gradual subsident warming with high
temperatures forecast to approach the mid 90s by Wednesday.
Upper-level ridge to maintain mainly dry conditions through the
remainder of the work week. However, a weakness in the ridge
across Arkansas is forecast to bring increased chances for
afternoon showers and thunderstorms next weekend. /05/
