Area forecast discussion 
National Weather Service Shreveport la 
1148 am CDT Friday Mar 19 2010 


Discussion... 
pressures are falling off over the west and the gradient is going 
to continue to allow for some gustiness this afternoon. Temperatures are 
nearing yesterday/S effort and would be on pace for middle to upper 
70s if not for the wind. Low to middle 70s from west to east should 
work out today with still some upper 50s over the northwest and mlu 
pushing 70 already. Few cumulus so far and the sounding was a bit drier 
with the inversion lower...near 5kft. Scattered clouds at that level 
will crop up for much of the area. Meanwhile...the visible Sat is 
showing that and a good deal more clouds just our west where dew points 
are in the 50s. Little change needed at this time...just a few tweaks to 
highs and new NAM winds loaded in for the afternoon. /24/

Aviation... 
a digging shortwave trough is forecast to move through The Four 
Corners around 20/0000 UTC. The movement of this feature should 
push a cold front toward the ih-30 corridor around 20/1200 UTC... 
toward the end of this forecast period. Limited moisture return in 
advance of this system will likely result in any rain showers/thunderstorms and rain occurring 
along or just ahead of the front...probably after 20/1200 UTC. In 
the meantime...expect VFR flight categories to continue across area 
terminals with increasing S winds. VAD wind profile from kfws and 
kshv are noting 25-45kt winds at 2k feet...so mentioning some wind 
shear in the tafs at all sites until around mid-morning...when the 
winds will mix down to the surface... /23/
