December 2018: Sunshine Returns New Years Eve
JB is too east coast biased because he lives in Pennsylvania, but overall I think he’s alright.

So...no wintry mix for us?
Just because you're disabled, you don't have to be a victim

We’ll probably see some winter weather events over the next 3 months, but not tonight lol not even close tbh.
Folks cut AccuWeather checks, and their forecasts are terrible. TWC is not much better.harp wrote: ↑Thu Dec 13, 2018 9:54 pmThanks. Yep, JB has been doing this his whole life and people still write him checks, so he must be good. I'm also interested to see what srain says.CRASHWX wrote: ↑Thu Dec 13, 2018 9:48 pmI can’t explain anywhere as good as Srain or any of those steely eye weather guys but I know that a great deal of JB’s weather forecast come from a combination of things and in reality he relies very little on model to model runs. He also does not have a great deal of faith in the GFS when it comes to winter weather. JB said it has feed back problems and under estimates the cold and it’s push. How do you judge how good Joe is...well he handles a lot of really big clients that are highly effected by weather and they keep writing him big checks year after year... He is a bit goofy but I think he is a bout as good as you get on long range and verification. But I guess simply put the Global models just don’t seem to look at all the thing he looks at to make a prediction.harp wrote: ↑Thu Dec 13, 2018 8:20 pm I have a question. I keep reading about the end of the month and into January being colder. I also watched a video from JB and he explained the factors that are going to cause these changes, including sudden stratospheric warming. When will these changes begin to show up in the models? More specifically, the GFS, which really shows nothing through the 29th. If someone could explain this, it would be appreciated. I am just west of New Orleans, but follow this forum during this time of year.
JB's hit and miss, but entertaining. A lot better at weather than climatology!

In general, a Sudden Stratospheric Warming (SSW) event is where you have very strong warming in the Stratosphere. Sometimes up to 50 degrees celcius. This, as a result, can really weaken upper-level flow and reverse the prevailing wind direction, especially for the higher latitude locations. Eventually (after a couple days to weeks) this can influence weather over parts of Europe and North America in particular. Some of the bigger cold events occur when this happens. While forecasting temperatures in the stratosphere have improved a lot over the years, it still can be difficult to forecast the impacts to the lower latitude because of how long it can take to propagate south.
Models do indicate an SSW event is possible towards the end of the month, but the impacts might not be felt until closer to New Years. At that point who gets impacted the most comes into question, and a lot of the models indicate the east coast could see more impacts than central/west U.S. I also included some links below going into more detail and a basic forecast map. Sorry if the explanation felt rushed, been a busy couple days and I can explain more in detail later if you want.

May see a pellet or two but that is probably about it. The warm pocket is deeper than models were indicating earlier plus surface temps are going to be so warm. Most of the actual winter precip will stay over Central and North Texas.

Looking at Christmas, nothing really shouts "interesting" weather. Models are indicating an omega block to occur over the western half of the U.S. in the next couple of days and shove any cold air east before finally shearing out and a zonal flow sets up. Looking at the NAO and AO also indicates not much is expected until after Christmas (think more towards the New Year). While there is still plenty of time for models to adjust, nothing synoptically really indicates a strong Meridional flow that could create winter weather for the state. I think the CPC's forecast of neutral temperatures across much of the United States is looking pretty good so far. I know there has been a lot of talk about a Sudden Stratospheric Warming event, but that doesn't really look likely until late December and impacts may not be felt until January.

Just example on Joe...nailed Harvey, Sandy, Katrina, about every snow event in our area and did all well in advance...just my opinion he is legit but he does have pretty impressive track record and certainly is paid well by likes of some very large clients who put a tremendous amount of trust in his ability...that said after years of lurking here and other weather forums there guys on this forum that I trust just as much....again JMO

I'm sorry but did I miss the wind that was heavily forecasted the past few days? I'm looking outside and the flags are slack. lol

Light rain showing up via radar imagery this morning circling
around the upper level low pressure system which is continuing to
shift east across SE TX. Short term guidance shows most of the
light rain ending by noon today as the system shifts further to
the northeast out of the region. Some terminals that have seen the
precipitation this morning have seen visibilities and ceilings
lower to temporary IFR/LIFR criteria. Otherwise, mostly MVFR
conditions expected through the day and into the evening across
all terminals. Winds should pick up in speed out of the W NW
becoming gusty this morning through the afternoon hours. VFR
conditions work their way from NE to SW early Saturday in the
extended portion of this TAF period, with gusts falling off and
wind speeds lowering to between 10 to 16 kts.

DISCUSSION...
At 1 AM, low pressure was located near the Arklatex with a cold
front over the west central Gulf and a secondary trough of low
pressure extending SW from the low across Central TX. 00z 850 mb
analysis showed a well defined low pressure system over N TX with
a trough extending south toward the middle coast. 850 mb moisture
was still plentiful over the eastern third of the state, east of
the weak trough axis. At 300 mb, a well defined upper low was also
located over N TX with a nice split in the upper level winds over
NE TX. The upper low is progged to sink SE today as the surface
low scoots to the east. Patchy light rain will accompany the upper
low as it moves across the region. The forecast soundings for
KCLL shows the lowest 5000 feet above freezing and not much in the
way of saturation at 10 C so although can`t completely rule out a
few snow flurries, feel the primary precipitation type will be
light rain or drizzle. Best rain chances should remain over the
northern third of the CWA closest to the best diffluence. Strong
CAA coupled with the cloud cover and mixing from winds will keep
temperatures very cool today with high temperatures struggling to
reach the middle 50`s.
As for the Wind Advisory, well, it`s been in effect for a while
and wind observations have been reluctant to meet Advisory
criteria. The gradient is expected to tighten later this morning
and the latest LAV/ECMWF guidance supports an increase in wind
speeds. Have reconfigured the Wind Advisory to remove some of the
far NW counties and start the Advisory at 17z and continue it
through 23z. Areas close to the Gulf/Bays should have very strong
winds this afternoon. As for Harris County, it`s a large county
and the stronger winds will be near KHOU toward the bay. The NW
half of the county will probably stay below Advisory criteria.
Clouds will linger tonight as the upper/sfc low depart the
region. On Saturday, clouds in the morning will gradually erode
as weak high pressure builds into south central TX. The high will
reside over the area through Monday before shifting east Mon
night. Cirrus clouds will be streaming into the area Sun-Sun night
but no precip is expected. Temperatures will begin to moderate
Sunday into Monday as 850 temps gradually warm. Sfc winds will
remain out of the north so the warm up will be slow.
Things look a bit more interesting for Tuesday night into
Wednesday as a strong short wave moves into the southern plains.
PW values increase to around 1.25 inches and fcst soundings over
the southern half of the region become saturated. Jet dynamics
look good early Wednesday but a confluent upper flow by late Wednesday
aftn should provide a quick end to precip. The end of next week
looks dry with near to slightly above normal temperatures. 43
MARINE...
The cold front that pushed through the region yesterday has left
behind a rather strong pressure gradient resulting in moderate to
strong west northwesterly winds. The upper level low pressure system
will continue to skirt SE TX pushing off to the northeast later this
morning and into the afternoon hours. Therefore, the pressure
gradient should slacken throughout the day and the moderate to
strong west northwest wind should become more moderate northwesterly
winds by the afternoon hours. Gale Warnings have been canceled for
both Matagorda and Galveston Bays as observations have remained
below criteria and global guidance has also trended lower in the
most recent runs. Small Craft Advisories have been substituted in
place of the Gale Warnings across both bays. Gale Warnings remain in
effect across the Gulf waters with the strongest winds and highest
seas remaining in the western offshore waters this morning. Both
winds and seas should lower throughout the afternoon and into the
evening hours. Later this afternoon, Gale Warnings will transition
into Small Craft Advisories across the Gulf waters through Saturday
morning.
These west to northwesterly winds will also result in low tide
levels with water levels falling between -1.0 to 1.5 feet below
MLLW. Impacts will likely be felt during the low tide cycle this
afternoon. Low Water Advisories remain in effect through 6 PM this
evening for both Matagorda and Galveston Bays.

KCLL shows the lowest 5000 feet above freezing and not much in the
way of saturation at 10 C so although can`t completely rule out a
few snow flurries, feel the primary precipitation type will be
light rain or drizzle. Best rain chances should remain over the
northern third of the CWA closest to the best diffluence. Strong
CAA coupled with the cloud cover and mixing from winds will keep
temperatures very cool today with high temperatures struggling to
reach the middle 50`s.
As for the Wind Advisory, well, it`s been in effect for a while
and wind observations have been reluctant to meet Advisory
criteria. The gradient is expected to tighten later this morning
and the latest LAV/ECMWF guidance supports an increase in wind
speeds. Have reconfigured the Wind Advisory to remove some of the
far NW counties and start the Advisory at 17z and continue it
through 23z. Areas close to the Gulf/Bays should have very strong
winds this afternoon. As for Harris County, it`s a large county
and the stronger winds will be near KHOU toward the bay. The NW
half of the county will probably stay below Advisory criteria.
Clouds will linger tonight as the upper/sfc low depart the
region. On Saturday, clouds in the morning will gradually erode
as weak high pressure builds into south central TX. The high will
reside over the area through Monday before shifting east Mon
night. Cirrus clouds will be streaming into the area Sun-Sun night
but no precip is expected. Temperatures will begin to moderate
Sunday into Monday as 850 temps gradually warm. Sfc winds will
remain out of the north so the warm up will be slow.
Things look a bit more interesting for Tuesday night into
Wednesday as a strong short wave moves into the southern plains.
PW values increase to around 1.25 inches and fcst soundings over
the southern half of the region become saturated. Jet dynamics
look good early Wednesday but a confluent upper flow by late Wednesday
aftn should provide a quick end to precip. The end of next week
looks dry with near to slightly above normal temperatures. 43

The cold front that pushed through the region yesterday has left
behind a rather strong pressure gradient resulting in moderate to
strong west northwesterly winds. The upper level low pressure system
will continue to skirt SE TX pushing off to the northeast later this
morning and into the afternoon hours. Therefore, the pressure
gradient should slacken throughout the day and the moderate to
strong west northwest wind should become more moderate northwesterly
winds by the afternoon hours. Gale Warnings have been canceled for
both Matagorda and Galveston Bays as observations have remained
below criteria and global guidance has also trended lower in the
most recent runs. Small Craft Advisories have been substituted in
place of the Gale Warnings across both bays. Gale Warnings remain in
effect across the Gulf waters with the strongest winds and highest
seas remaining in the western offshore waters this morning. Both
winds and seas should lower throughout the afternoon and into the
evening hours. Later this afternoon, Gale Warnings will transition
into Small Craft Advisories across the Gulf waters through Saturday
morning.
These west to northwesterly winds will also result in low tide
levels with water levels falling between -1.0 to 1.5 feet below
MLLW. Impacts will likely be felt during the low tide cycle this
afternoon. Low Water Advisories remain in effect through 6 PM this
evening for both Matagorda and Galveston Bays.

Upper low passed over the Northern half of SE Texas and is nearing the Sabine River. What a difference a day makes. It's cold and blustery out there with wind chill values in the upper 20's to 30's. Bundle up!

You have to admit, this didn’t quite pan out like expected. The front was supposed to come through during the day with crazy winds. Didn’t happen. We left our concert about 7 and it was dead still calm outside. I was wondering “what the heck??”
The front and winds didn’t arrive until after 7, after dark, and so the winds were not as intense as expected. Sure there were some decent gusts but this was not quite what was advertised...

Some examples of bright banding northeast of Conroe currently as the dry snow starts to melt around 2-3kft in the air. That is where your hydrometeor classification is showing more of wet snow/graupel and more returns are reflecting back towards the radar. Not exactly a textbook example but still cool to see.

A cold, light mist here with calm winds. Definitely some comfort food (perhaps chili or chicken & dumplings) is on the menu for today.
Cheers, everyone!
