11/12 – Payton’s Sunday Night Forecast
An interesting feature exists in the coastal waters with multiple
areas of rotation along a seemingly stalled surface boundary.
Enhancement of precip occurred as a jet associated with an upper
level trough has moved into the region. The rain shield should
gradually retreat southward as the upper trough brings a cold front
across the area and into the Gulf of Mexico tonight. The moisture
will finally flush out Monday afternoon as surface high pressure
builds into the area from the north.
Post frontal air mass is colder than the one currently in place over
the forecast area, but not by much. High temperatures may fall a
couple degrees or so over the next few days, but thats about it.
Drier air filtering into the area will drop dewpoints into the upper
40s. This combined with clear skies and light winds will allow for
better radiational cooling Mon-Tues nights. Overnight temperatures
will follow closely to the dewpoints which will bring lows to near
50 for many locations.
Later this week a slow moving upper trough to the north this week means little
change expected in the local weather. Expecting an extended of clear
skies and mostly near normal temps. Highs will be creeping back up
into the mid/upper 70s by later this week as the upper trough to the
east moves out into the Atlantic Ocean. The next chance of rain and
more cool down will be next weekend. At the moment models and
are not quite in agreement on how strong the the trough
will be. Meaning, model blend temp output makes the most sense for
