Yes we have history in the Atlantic Basin Hurricane Season. We now have TS Eta. The latest named tropical cyclone.

Area Forecast Discussion
National Weather Service Houston/Galveston TX
306 PM CST Sun Nov 1 2020

.SHORT [Through Tomorrow night]...

The cool front is still making its way through the area bring in some
cooler and drier weather. Not going to see a lot of the effects
other than some cooler lows tonight in the mid to upper 40s and
highs tomorrow around 70. Humidity will decrease as will overall
getting to around 35-30% in the day making it quite pleasant with a
northeasterly breeze. Overall, quite weather as the high pressure
ridges over SETX and settling in. 35


.LONG TERM [Tuesday through Sunday Night]...

Benign weather conditions continue throughout the week with a
persistent high pressure system dominating the Plains. Warm south to
southeast air advection will develop behind the surface high
pressure late Tuesday through Friday. This will result in
temperatures slightly warmer than previous days and a few degrees
warmer than average for this time of year. Highs will mainly range
from the mid 70s to near 80. A slight and gradual increase in
surface dewpoints/relative humidity is also expected into the
weekend.

Upper level pattern changes toward the end of the week as a longwave
trough develops over the Pacific Northwest and an upper-level low
moves over the Gulf. Global models show a potential for active
weather by Saturday and Sunday as low-level Gulf moisture increases
(PWATS around 1.5 inches) and the upper-low pressure system moves
through. There is still uncertainty given discrepancies between
models; thus, have only kept slight chances for rain next Saturday
and Sunday. 05

.AVIATION [18Z TAF Issuance]...

High pressure and a dry airmass allows VFR conditions to prevail.
Winds will shift from southerly to northerly tomorrow morning with a
reinforcing cool front passing through the TAF sites. A few fair
weather CU clouds will probably be see across the area around 020-
025 through the day today, but no MVFR CIGS are expected at this
time. 35&&

.MARINE...

Moderate to strong northeast winds persist this afternoon in the
wake of a departing surface cold front. Gusty winds from 20 to 30
knots are expected to continue this evening through Monday morning
before northerly flow mixes out and a surface high pressure moves
overhead. Building seas are also expected with values up to 7-8 feet
offhsore. Given that, a Small Craft Advisory remains in effect
through 12 PM CST Monday. Northeast winds will gradually veer to the
east-southeast by Tuesday as the aforementioned high moves east of
our region. Seas could increase offshore around 3 to 6 ft towards
the end of the week thanks to tighter pressure gradients and
increasing swells associated with Tropical Cyclone Eta over the
western Caribbean. 05

Shallow cold air and overrun, wxtroll.
Right, so it wouldn't have been near as cold if the clouds weren't overrunning, given how shallow the cold air was. Nothing to be uptight about, man.
