SUNDAY - MONDAY
An area of disturbance will spread
south towards the area today, then will move through the area tonight
into Monday.
As the trough moves south Sunday, an
associated cold front will move through the area. Scattered showers
and storms should be able to develop along the front, especially
north of I-44 as instability increases with the heating of the day.
As the front moves south of I-44 tonight into Monday coverage should
decrease but a few showers/storms will remain possible.
As instability increases Monday
afternoon and evening a few strong storms will be possible, again
mainly north of I-44. The main risk will be winds in excess of 50 mph
and hail to the size of nickels in a few of the strongest storms.
Highs this Sunday afternoon should be
able to top out in the lower to middle 80's as highs in the lower
80's are expected on Sunday. An upper level ridge will remain across
the western CONUS through much of the week leaving the area in a
northwest flow upper level pattern. This will keep the below normal
conditions in place across the area as highs in the upper 70's to
lower 80's occur each afternoon.
TUESDAY - THURSDAY
At this time we do not expect much in
way of rain behind the front Tuesday through Thursday. Late this week
into the weekend we may see moisture from the remnants of Harvey try
to spread north into area. This could bring some rain chances to the
area but confidence is low in the track of the system and medium
range models remain inconsistent from run to run and each other.
TD "Harvey" will then track
across northern Mississippi on Thursday and western Tennessee
Thursday night. Almost all of the precipitation will remain southeast
of the CWA, but up to a quarter inch may affect the far southeast
portion of Oregon county.
LABOR DAY WEEKEND
The upcoming holiday weekend looks to
be dry across the area with temperatures in the 70s to low 80s on
Friday, but warming back to more normal readings in the mid to upper
80s by Sunday and Monday in the wake of the tropical system.
A cold front is forecast to push
through the area Monday night into Tuesday morning which will bring
the next chance of showers/thunderstorms to the region from the
northwest. This will usher in a cooler and drier air mass for Tuesday
into the middle of next week.
