10/12 – Payton’s Thursday Evening Forecast

Gradually lowering humidity will continue to filter
into the mostly inland portions of the forecast area through
Friday. This lower humidity will result in cooler nighttime and
early morning temperatures that will also be most noticeable over
the more inland areas and less noticeable along coastal sections.
Unfortunately, the dry air and abundant sunshine during the day
will continue to lead to well above normal high temperatures in
the upper 80s to around 90 degrees on Friday and Saturday.

A tropical wave is expected to move west across the east
central to southeast Gulf of Mexico on Friday and Friday night,
then the south central to central Gulf Saturday and Saturday night
and into the west central to southwest Gulf on Sunday. This
feature will likely bring deeper subtropical moisture northwest
towards the central Gulf coast Saturday night into Sunday, and
have chances of showers and thunderstorms returning to mainly
coastal and offshore areas Saturday, but across most land areas on
Sunday. Temperatures are expected to remain warm with higher
humidity briefly returning.

A stronger cold front will push through the forecast area Sunday night
into Monday, although it may be shallow at first since the models
indicate potential for over-running rainfall with the sub-
tropical moisture in place behind the initially shallow frontal
boundary Sunday night through Monday night. We should finally see
fairly widespread 50s to lower 60s for lows Monday and Tuesday
nights with the highs also lowering to the mid 70s to lower 80s.
The surface to mid level wind flow will likely veer to more
easterly by mid week as high pressure over southern states slides
east, so humidity levels will likely recover with some chance of
showers returning to at least coastal areas.
