Today and Tonight.

The line of showers and storms have exited the region and now we
wait for the upper low to swing into the area. We are seeing some
patchy dense fog this morning across portions of northern Central
Alabama, particularly sheltered locations. As the upper low works
into the winds will begin to pick up. This should help eradicate
any fog, but low clouds will build in along with isolated to
scattered showers through the day. Winds are also going to be a
concern with 15 to 25 mph sustained this afternoon with gusts up
to 35 mph. This is really going to be a concern in areas that did
have damage from the storms as additional trees/limbs and debris
could fall due to the wind. 

As we move into the evening hours, winds should begin to subside,
but slowly as we continue to see the cold air work into the area.
Temperatures will drop in the 30s areawide by Wednesday morning.
Overall not expected any major areas of freezing temperatures,
with the exception of a few locally sheltered areas in the north.
Also winds should remain around 5 mph so frost should not be an


Wednesday through Monday.

High pressure builds into the area on Wednesday, with temperatures
in the low 50s north to low 60s south. We will see the winds begin
to dissipate shortly after sunset and then temperatures will drop
once again into the 30s. There is a possibility of seeing freezing
temperatures in the northeast and portions of the northwest.
Further south temperatures may remain above freezing, but areas of
frost can be expected. Did not issue a Freeze Watch this morning
as confidence is just not high enough and still too early for a
frost advisory but the potential is there so take precautions now
if needed. 

We will see temperatures slowly modify warmer each day through the
the end of the week and into the weekend as southerly flow returns
to the area. A weak shortwave will work toward the area on Friday
but moisture will be limited, so just included a slight chance of
rain for Friday. The ridge begins to break down on Saturday, but
remains strong enough to keep the next system draped across our
north, so for right now will only go with pops across the north
and see where the boundary sets up over the next week. 

By Monday the ridge begins to amplify in the Plains and models
indicate a backdoor wedge to build into place for Sunday through
Monday. This may increase rain chances for the first of next week,
but will need to be monitored for the changes and the extent of
the rain as we get closer to this time.
