.SHORT TERM...
(This afternoon through Monday)
Issued at 1113 AM CST Sun Dec 7 2025

Light rain that was hanging out along the coast this morning has
now pushed offshore for the most part, however we will see a
return of rainfall later today. Later today a cold front will
push through the area and along with it we will see another round
of showers, mostly in the evening hours. Additionally throughout
the day today, we may see some patchy fog in some areas as a cold
front pushes towards the area and a warm front sits offshore.
While this won`t likely get to a widespread dense situation, there
could be patchy areas of low visibility.

Our cold front tonight will bring a cooldown through early week,
with Monday`s high temperatures sitting in the mid to upper 50s
for most areas. The front will also dry things out once it passes
through, with PoPs falling down to ~0% after it passes. Surface
high pressure starts to build in Monday afternoon, which will
dominate the forecast through at least mid week.

.LONG TERM...
(Monday night through Saturday)
Issued at 1113 AM CST Sun Dec 7 2025

The beginning of the long term will see high pressure over the
region, keeping conditions fairly quiet. Our cold front from
Sunday night will bring our coolest morning lows Tuesday morning.
MinTs will be in the low to mid 30s for areas north of the lake
and the low 40s south of the lake. A couple models hint at these
being even lower, but with no majority consensus decided not to
adjust them and left NBM numbers in. Tuesday afternoon highs will
be just a touch warmer than Monday, but by Wednesday afternoon
highs return to the upper 60s for most. Thursday will be up close
to a good 10 degrees above our climate normals this time of year,
with MaxTs in the low to mid 70s.

In terms of precipitation, the majority of the period will remain
dry, with the only increase in PoPs early Friday morning and even
that is only about ~15-25%. There are hints at a system late in
the period that could bring our next freeze, but there isn`t a ton
of model consistency with this so it will be just something to
watch.

.AVIATION...
(18Z TAFS)
Issued at 1113 AM CST Sun Dec 7 2025

A wide variety of conditions across the area late this morning,
ranging from VFR to IFR. Low vis and cigs will likely be common
at all terminals today. Low status is hanging around for many
areas and will continue to be around throughout the day today.
There may be some slight improvement in conditions through the
afternoon, but they will fall again later this evening.

.MARINE...
Issued at 1113 AM CST Sun Dec 7 2025

A strong cold front will push through Sunday night with offshore
winds near 20-25 knots developing. Small Craft Advisories will be in
effect from midnight Sunday night through Monday afternoon. High
pressure quickly builds back into the area Monday night into This
relaxes winds and seas through midweek, with winds becoming onshore
and light again by later in the week.
