.SHORT TERM...Tonight through Sunday Night/

In wake of the cold front moving across North Louisiana and East 
Texas this afternoon, drier air will move into the Four State 
Region clearing out the remaining low level clouds as high 
pressure on the surface and aloft build into the region. High 
level moisture will spread into the area but will be thin and not 
allow the cold temperatures to dip as low as expected for Sunday 
night under less cloud cover. No rain is expected through the 
short term as dry weather is in store. Low temperatures overnight 
will range from near 40 North to the lower 50s South with slightly
cooler reading for Sunday night ranging from the upper 30s North 
to the upper 40s Southwest. Daytime high temperatures on Sunday 
will range from near 60 Northeast to the upper 60s Southwest. /06/

.LONG TERM.../Monday through Friday Night/ 

Surface high pressure stretching from the eastern seaboard to the 
Red River Valley combined with weak upper-level ridging aloft to 
maintain dry conditions across the region on Monday and Tuesday. 
Temperatures on both days to range from highs in the lower 60s to 
lows in the 40s. 

Gradual warming trend expected on Wednesday and Thursday as moisture 
and cloud-cover increase due to a weak disturbance in the Gulf of 
Mexico. Southwest flow aloft to maintain mostly cloudy skies with 
scattered showers and isolated thunderstorms each day. 

Northwest flow aloft to sweep moisture south and eastward late in 
the work week with skies gradually clearing from the northwest. 
Temperatures on Friday to range from highs in the upper 60s to lows 
in the 50s. /05/
