.DISCUSSION...
Through tonight: The coolest morning so far this fall season is 
underway across the area. Though there is a stream of high cirrus 
over much of the region, this is a rather thin layer which is having 
a minimal impact on radiational cooling (though somewhat thicker 
high clouds exist just south of the area). Patchy frost will remain 
possible through shortly after sunrise in the cooler pockets over 
the northeastern part of the forecast area; thus we'll maintain 
mention of this in the HWO/graphical products.

Otherwise, calm conditions can be anticipated over the next 24 hours 
as the surface high shifts off the Atlantic coast. A surface low 
will begin to take shape along the northwestern Gulf coast today. 
Later today and into tonight, moisture associated with this system 
will begin to overrun the coastal baroclinic boundary, leading to an 
increase in clouds across the area, particularly across South 
MS/South LA. However, the low levels will remain quite dry, making 
the prospects for measurable rain scarce through tonight. /DL/

Tuesday through Sunday night...Surface high pressure and upper 
ridging will continue to prevail across the area on Tuesday, with 
highs around 70 degrees for most of the area. Moisture will begin to 
increase across the area Tuesday night into Wednesday as the upper 
ridge shifts to the east. An upper trough will pick up the remnants 
of Hurricane Willa and the associated moisture will move east across 
Texas and into the western portions of our CWA Wednesday night. Both 
the GFS and the ECMWF develop a surface low and move it across the 
northern gulf coast on Thursday and Thursday night. Thursday will be 
a wet day as the associated rainfall moves across the area. The 
upper trough will move through the region Thursday night, with the 
bulk of the rain ending from west to east through this period.

Surface high pressure ridging and dry conditions will return by 
Friday afternoon and continue through much of Saturday. The global 
models are in decent agreement on the timing of a cold front moving 
across the area Saturday evening into the overnight hours. This may 
bring another round of showers to the region, with high pressure 
building back in Sunday into Sunday night./15/
