NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Austin/San Antonio Texas 
405 am CDT Sat Sep 5 2015 


Short term (today through sunday)... 
moisture has increased overnight and it is spreading from the 
southeast(coastal plains)towards the northwest(southern Edwards 
plateau). Dewpoints are averaging from the lower 70s across The 
Hill Country/southern Edwards Plateau to the upper 70s across the 
coastal plains. There are few sites already reporting patchy fog 
and expect this trend to continue over parts of the eastern 
counties and along and north of the Escarpment through about 8 or 
9 am. Most of the hires solutions bring spotty showers this 
morning across the eastern two-thirds of south central Texas. This 
solution...cant be rule out since there is an inverted trough 
moving across the area and that will be enough of a lift for some 
light rain/precip(in spite of forecast soundings showing dry 
conditions from the surface to about 6kft). Overall...expect 
mostly cloudy skies early this morning becoming partly cloudy 
around noon and high temperatures in the middle to upper 90s over 
most areas and up to 103 degrees across the southern part of Rio 
Grande. Due to the increased moisture...heat indices could range 
from 105 to 107 along and south of Highway 90 and 57 for few hours 
this afternoon. Scattered showers and few thunderstorms are 
expected mainly across the coastal plains and parts of the 
southeast counties of south central Texas. Rainfall amounts will 
generally be around few hundredths to one quarter inch and up to 
three quarter inch over few locations. 


Low clouds return overnight into Sunday morning with partly cloudy 
skies and dry conditions expected on Sunday. Highs are forecast 
to be in the middle to upper 90 most places and near 101 across the 
southern Rio Grande. 


&& 


Long term (sunday night through friday)... 
an upper high will maintain south central Texas relatively dry 
through the middle of next week with light to moderate showers/isolated 
storms mainly affecting the coastal plains. The upper high is 
forecast to shift to the southwest and opens the door for a cold 
front to push across the area the latter part of the week. This 
forecast package reflects the ecm solution for the extended period 
of Thursday and friday(similar to previous package). The GFS 
continues to have difficulties handling the timing and placement 
of the cold front for that period. Will keep adjusting the weather 
packages accordingly as the ecm and GFS come to a better solution 
in future runs. Overall pattern for later in the week looks wet 
with beneficial rainfall for the two-thirds of south central 
Texas.
