Area forecast discussion 
National Weather Service Shreveport la 
950 PM CDT Tuesday may 21 2013 


Discussion... 
strong to severe thunderstorms will be moving east of the forecast 
area into eastern Louisiana shortly. However additional convection 
to follow for several more hours across East Texas...northern 
Louisiana and southern Arkansas. Will be able to remove probability of precipitation 
across southeast Oklahoma and adjacent northeast Texas on update. 
The Tornado Watch will expire at 10 PM as issued. 


Some minor changes to the forecast...mainly to adjust temperatures 
and dewpoints down. Lowest readings for the night may already have 
occurred in several areas due to the cooling from the rain...so 
forecast will be for mainly steady temperatures over much of the 
area. 


Updated products out shortly.

Aviation... 
initial line of convection now making its way through kmlu and has 
produced widespread 40-50 knots wind gusts across area terminals 
earlier in the evening. Additional development is noted to the SW of 
the region...and also appears to be strong. Convection will remain a 
possibility into Wednesday...as the cold front slowly tracks across 
our region. Expect variable winds/flight categories due to convection 
ahead of the front...and north winds with improving conditions after 
frontal passage...as rain ends from northwest to southeast during the day Wednesday. /12/
