is lagging just a little behind that to the W over E TN/W NC. We 
only have some lingering stratus in the northern half of AL still 
attributed from this system. With the upper system moved off to the 
E finally, we should be able to have a short break from any light 
rain showers during the day today. Our next frontal system is still 
off to the NW. However, we don't get any good low level onshore 
southerly flow ahead of its arrival. We keep dew points in the 50s 
which should help keep our instability down some. This surface front 
is expected to push toward the Mississippi River Valley today and 
across MS toward W AL tonight. So our rain break will be short with 
rain chances increasing from W to E with the best chances along and 
west of I65/59 after midnight for some rain showers mainly, but a 
few thunderstorms in the far W toward daybreak closer to the front 
are possible. The best instability should hold off until during the 
day.

.LONG TERM...
Thursday through Wednesday.

A highly amplified pattern will persist through the rest of this 
week and into the early part of next week. A deep trough is over the 
Eastern US Thursday and Friday.  A shortwave moves through the base 
of the trough Thursday, sparking a weak surface low development that 
will push through Central AL during the day Thursday. Modest 
instability could make its way into the area ahead of the cold front 
that is associated with the surface low; however, I expect the 
forcing to remain relatively weak, limiting any severe potential. 
Will maintain mention for slight chance of thunder with the rainfall 
on Thursday, but will not introduce any severe wording in the HWO at 
this time. 

The surface low and associated cold front will slide off to our east 
fairly quickly, and by Friday morning, rain chances across Central 
AL look limited as dry air moves in behind the departing low. 
Surface high pressure builds in over the weekend as an upper level 
ridge slides over the eastern half of the CONUS. This will in a 
warming trend for our afternoon highs over the weekend with mostly 
clear skies.

The first half of the next week looks to follow a similar trend as 
the weekend. Synoptic scale ridging persists over the Eastern CONUS 
as a trough digs into the Pacific NW and into the Great Basin by 
Monday evening. The high pressure over the Southeast US blocks the 
trough to our west through at least mid-week, resulting in warm and 
dry weather.
