Scientific Forecaster Discussion
Area forecast discussion

for 12z aviation.
Looks like we will squeeze out one...maybe two...dry days before
tropical moisture starts to stream into the area from the Gulf.
Models continue to depict an upper level trough moving from the
plains states into the Ohio Valley Friday and Saturday...while a
shortwave pivots moves northward out of the Gulf into the
southeast states. These two features will likely bring a
noticeable increase in clouds and rain chances to central Alabama
over the weekend. No major changes were made to the ongoing
forecast...and will keep the likely probability of precipitation for many areas Saturday
into Saturday night. An west-east oriented upper level ridge is
forecast to become reestablished across the southern tier of the
country early next week. This should drop daily rain chances down
to climatology levels (at most)...while also causing afternoon highs to
climb well into the 90s once again.
12z taf discussion.
VFR conditions are expected to continue throughout the taf cycle.
Winds will take on a southerly component today with highs clouds
streaming in across the taf sites.
