1034mb high pressure will build into the region today. Skies will 
clear a little bit more in the north, with partly cloudy skies 
south. The center of the high pressure will slide into the Great 
Lakes region overnight, while slightly building even more. Overall 
winds will not calm all the way down, so prime radiational cooling 
is not expected tonight. Although the well protected valley may drop 
quite a bit. Look for highs to be in the upper 60s north to upper 
70s south, with lows in the upper 40s north to upper 50s south. As 
mentioned earlier. well protected areas in the north may drop into 
the low to mid 40s.

.LONG TERM...
Friday through Thursday.

The ridging pattern begins to flatten across the Southeastern US as 
a trough slides into the Northern Plain, pushing a cold front 
through the Midwestern States. A pre-frontal shortwave develops
and moves across the Mid-MS Valley, spreading eastward through TN
and Northern AL late Friday night into Saturday morning. Lift 
associated with the shortwave and the approaching cold front will 
allow for rain development mainly after midnight north of I-59. 
This will spread southward through the day on Saturday, reaching 
the I-85 corridor during the early afternoon. Locations south of 
I-85 could see a few rumbles of thunders with the rain as it 
pushes through in the afternoon and some modest instability is 
able to work its way in, but generally I don't expect much 
thunderstorm development with this system. 

The cold front pushes south and east of Central AL by Saturday 
night, so I've cleared out all mention of rain or thunderstorms 
after midnight. A cooler and drier air mass gets advected into the 
region with northerly flow persisting most of the day Sunday. 
Therefore, high temps Sunday will generally be in the mid to upper 
60s in the south with some locations in the northern counties 
struggling to reach 60 degrees. The center of a surface high 
pressure system slides through the Ohio River Valley Sunday evening 
into Monday as ridging aloft builds in across the Southeastern US. 
This will lead to synoptic scale subsidence, clearing skies 
overnight Sunday into Monday, which will allow for effective 
radiational cooling. This will setup for potentially our coolest 
night of the season so far with Monday morning lows in the upper 30s 
in the north to the low 40s for most of Central AL. 

By Monday afternoon, the surface high pressure system has shifted 
over the Outer Banks, veering our winds more southeasterly and 
southerly. This will act to moderate temps across Central AL Monday 
through Wednesday to seasonable diurnal ranges. 

Wednesday into Thursday, another trough slides into the Central 
Plains, developing our next system that will move in just beyond the 
extended period. Details are uncertain as models have not shown run 
to run consistency on the evolution or timing of the trough. 
Therefore, I have introduced 30-40 PoPs area-wide Wednesday and 
Thursday, but will need to adjust up or down depending on how models 
trend over the next few days.
