VFR conditions to prevail for the next 24 hours. A few isolated 
showers are possible this afternoon mostly to the east of Highway 
59. Dropped mention of thunderstorms and rain in tafs because strong subsidence 
over the area is limiting convection. Winds will be from the north-NE 
at 5 to 10 knots. 44

Previous discussion... /issued 904 am CDT Thursday Jul 30 2015/ 


Discussion... 
seeing more cloud cover across eastern areas this am as deeper 
moisture advects in from the east. Quite a difference 
between the 12z lch and crp soundings (2.2 vs. 1.5 inch 
precipitable water). Given this deeper moisture across eastern 
areas...and the latest hrrr reflectivity forecast...believe that 
the chance pop across the east and slight chance pop across the west is 
on track for this aft/eve. Maximum temperatures near 100 inland and lower to 
middle 90s coast appears on track as well. No significant changes to 
the ongoing forecast. 33
