Area forecast discussion
National Weather Service Birmingham Alabama
136 PM CDT Tue Jun 27 2017

Short term...
through tonight.

Central Alabama will continue to be under the influence of a
large surface high covering the eastern states. Northeast winds
underneath the surface high have produced below normal humidity
levels across the area this afternoon, with dewpoints in the upper
50s to lower 60s. Winds will become light easterly overnight as
the surface high slides off to the east. Models show another round
of cirrus arriving late tonight.

58/rose



Long term...
Wednesday through Monday.

Deep moisture advection will begin on Wednesday to our south as a
disturbance moves toward the Gulf Coast. Antecedent relatively
drier air should keep most of our area dry, but isolated
convection is possible across the far southern counties late
Wednesday afternoon into the evening.

Moisture quality is expected to surge on Thursday into Friday
with precipitable water values around 2 inches continuing into the weekend. The
combination of the Gulf disturbance moving inland and westerlies
aloft indicative of a troughy pattern, will lead to enhancement of
convective activity with 40-60 pops each day.

18z taf discussion.

Surface high pressure analyzed over eastern Illinois is helping
to provide fair conditions with north winds becoming breezy at
times, generally between 5 and 15 knots. Expect VFR conditions
through the period with clouds increasing from south to north
tonight and into Wednesday. Low level winds will become light
again tonight and will shift from the southeast at most sites by
early on Wednesday. Chances for thunderstorms and rain will develop toward the end
of this cycle toward midday on Wednesday at mgm and toi but
potential remains too low to mention at either terminal at this
time.
