.PREV DISCUSSION... /issued 359 PM CDT Fri Oct 30 2020/

Pleasant conditions across the area this afternoon, as low clouds
around this morning pushed into the Gulf yielding full late
October sun that has helped warm temperatures into the mid 60s.
Winds have continued to relax as an axis of surface high pressure
continues to slowly slide east and into the region. Temperatures
tonight will fall off quickly after sunset and bottom out cooler
than this morning due to the lack of cloud cover and lighter SFC
winds, with readings in the lower to mid 40s away from the coast.

A slight warming trend will ensue on SAT underneath westerly flow
aloft and with high pressure continuing to prevail at the surface,
though highs will continue to run below seasonal normals, reaching
to around 70 degrees. This slight warming will continue SAT night
and into SUN, with morning lows and afternoon highs each gaining
a few degrees. Trick or treat temperatures SAT evening should
start around 60 and shed a degree or two each subsequent hour.
Winds will be light and variable.

Another cold front is expected to push through the area during
the day SUN, bringing colder temperatures back to start the new
work week. Lack of appreciable MSTR return ahead of this boundary
coupled with little to no forcing for ascent will result in a dry
passage. North winds SUN afternoon will become a bit brisk and
gusty, but look to remain well below advisory criteria at this
time. Cold and dry SFC high will settle into the area by MON
night, with temperatures TUE morning the coldest of this forecast
period, ranging from the upper 30s across interior SE TX and
Central LA to the lower 40s along the I-10 corridor.

Deep layer ridging will dominate the mid-week period, with ridging
stretching across southern Gulf expected to keep any tropical
shenanigans that get going in the Caribbean well to our south.



Northerly winds will continue to relax with the approach of high
pressure from the Plains. A cold front is expected to push
through the coastal waters Sunday afternoon, with modest to strong
and gusty north winds expected in its wake. Small Craft
Advisories and/or exercise caution headlines will be needed from
late Sunday afternoon into Monday.
