Thursday-Sunday...
The extended forecast period will begin quiet and transition into a
an
active period into the weekend. Thursday will see a break from
the
rainfall and rain will return Friday evening into Saturday. A
series of shortwaves will move through the area over the weekend
bringing increased rain chances, drying in the
wake before the next
frontal system.
On Thursday, a surface ridging pattern over the Mid-West will bring
dry and quiet conditions ahead of the next
shortwave feature.
Afternoon temperatures in the lower to middle 50s are expected. With
sufficient cooling and
calm winds during the evening, overnight lows
are expected to drop to the mid/upper 20s to lower 30s.
As Friday afternoon progress, expect cloud coverage to increase as
an
upper level trough pushes a low pressure center, located near the
TX/LA Gulf coast, towards the
CWA. Low-level southerly
flow will
help
moisture from the Gulf return, which increases rain potential
areawide heading into the weekend. Rain showers are expected and an
isolated thunderstorm can`t be ruled out south of I-20. Any
accumulating
rainfall from this system will help relieve
drought
conditions.
As the
shortwave trough and associated low pressure center moves
towards the Atlantic coastline,
rainfall will come to an end
Saturday evening into Sunday.
A surface ridge axis settles over the
region, allowing for a brief drying period going into the beginning
of next week as stronger longwave trough/organized frontal system
approaches from the Central Plains. We will have to monitor the
system as there are signals for more organized convection, so stay
tuned. /SW/
