Short term
Through tonight.

Warm air aloft has capped convection across alabama this
afternoon. A few showers or thunderstorms still possible along a
low level trof across across south alabama, but removed rain
chances for the overnight hours. Skies should become clear this
evening as diurnal cumulus dissipates.

Long term
Issued at 335 am ct
Tuesday through Sunday.

By Tuesday morning, we will have our initial low making a speedy
exit across new england toward the atlantic. At the same time, a
low building off the lee of the rockies will move across the
central plains. This will pull our boundary over alabama back
northward and out of the state as a warm front.

Surface ridging then builds back in from the east across alabama.

At the same time, upper ridging will be the big player as it
first builds in from mexico across the gulf of mexico into the
deep south. It's size will be impeded temporarily by a developing
low pressure over the western atlantic between the caribbean and
bermuda. The tropical low will be of no threat to CONUS as it will
be moving away from the mainland. The upper ridging then spreads
by mid week to over much of eastern CONUS and into texas. Upper
ridging continues to be in control through the end of the work
week. This will allow for subsidence along with a dry airmass. The
ridging will also allow for warming temperatures as we head
through the latter half of the week. However, relative humidity
values will not be high with the dry airmass. So, afternoon heat
index values are not expected to reach critical levels. Air
temperatures in general though will be well above normal and hot.

The upper ridging decreases over NE CONUS by the weekend, but
remains in tact over the deep south. Temperatures do continue to
slowly creep up over central alabama. Even though we remain dry,
we will have to monitor future model runs as temperatures will be
possibly going into the upper 90s by the weekend for portions of
the area.

Aviation
18z TAF discussion.

Should not have any weather related issues for aviation through
this forecast period. An amplifying ridge will build over the
southeast which should keep the overall pattern fairly monotonous
for the next few days. An isolated shower may develop near our
southern terminals this afternoon, but confidence is too low to
add in at this time. Current vis satellite shows a field ofVFR
cumulus with ceilings expected to continue rising through the
remainder of the day. Trended somewhat towards some light, patchy
fog as winds calm around 12z at mgm and toi, but dry low level
air and relatively dry surface soils may limit fog development.

Therefore,VFR conditions should prevail.

Fire weather
Isolated to scattered showers and thunderstorms will be possible
through sunset across portions of central alabama thanks to a
low level frontal boundary. The system will weaken and move
northward tonight into Tuesday leaving dry and warm weather for
the remainder of the week and into the weekend. Although dry
weather is anticipated, afternoon relative humidity values are not
expected to reach critical levels. There are no fire weather
concerns at this time.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
