Texas winter wx thread (2009-2010)

[Weatherdude20]

The next big batch of precip. looks like heavy RAIN from the radar returns (SW of FTW). Will be interesting to see if there's a switchover across all of DFW.

Still snow "showers" here in North Arlington.

Sorry, I don't think so.

It warms up a bit as the precip lightens, but check down in Granbury, as the heavier stuff comes in it cools the atmosphere\drags down cold air and voila.

Stephenville is about to get clocked by either heavy rain\sleet\or snow depending on the transition.

I doubt that there will be a changeover to all rain over the entire Metroplex.

Remember that just south of I-20 has been referenced earlier this week as the battleground for the proper thermal profiles necessary to produce snow. Plus it's totally normal for temps to bump up as the sun rises higher. And this isn't an arctic air mass, just a cold one with temps marginal enough to support snow.

One interesting thing to me is that it almost appears as if there is some convective returns occurring SW of Ft. Worth.

Let me try this again ... for any of the pro mets, do you believe the H5 low will have enough cooling aloft to create snow chances in Austin tonight? Yesterday, I thought I saw a reference from one of you indicating this low wasn't all that cold as compared to the December storm system.

Precip going to end quickly for Austin...believe me I am bummed.

Thanks txagwxman ... that is kinda what I thought too after looking at the 12z GFS and NAM. This winter has truly stunk for my area of the state. Three years running now and no winter weather event. Unbelieveable.

From The HPC RE the 12Z NAM...

12Z NAM EVALUATION

ANY INITIALIZATION ERRORS WITH THE NAM DO NOT APPEAR TO
SIGNIFICANTLY IMPACT ITS FORECAST.

...SOUTHERN STREAM SHORTWAVE MOVING ACROSS SOUTHERN
PLAINS/SOUTHEAST...TONIGHT THRU SAT NIGHT.

WITH COLD AIRMASS IN PLACE...POTENT SHORTWAVE AND SFC CYCLOGENESIS
TAKE AN UNUSUAL SOUTHERN STORM TRACK...THROUGH THE GULF
COAST...DEEP SOUTH AND CENTRAL FLORIDA.

OVERALL...THE 12Z NAM IS WELL WITHIN THE GUIDANCE SPREAD FOR
DEPICTION OF THE UPCOMING EVENTS IN THE SOUTHERN PLAINS AND DEEP
SOUTH. ITS TREND OVER THE LAST TWO DAYS HAS SPED UP...YET REMAINS
SLOWER THAN THE 06Z/GFS-00Z/ECMWF. 12Z NAM SOLUTION AT H7 IS
SIMILAR TO THE OTHER GUIDANCE THROUGH 13/12Z ACRS THE NRN GOMEX
AND IN BETWEEN THE 06Z/GFS AND 00Z/ECMWF FOR SPEED/DEPTH WITH THE
H5 TROUGH AXIS. AT THE SURFACE...ITS 1006MB SFC LOW ON FRI/12Z IS
SIMILAR TO THE 00Z/CANADIAN WITH RESPECT TO STRENGTH BUT LEANS
CLOSER TO THE 00Z/ECMWF TRACK PROGRESSION ACROSS THE FL PENINSULA
AROUND 13/00Z.

Don't put those kicking shoes away yet Portastorm, if Wxman57 says there is more winter to come, I have a feeling central Texas will not get left out before it's all said and done. Got my fingers crossed for you buddy!

Tom Hale (KRLD) keeps saying we'll get "cooler air in here at noon." Where is this coming from?

[Brent]

Does anyone know what the biggest snowstorm in history was at DFW?

My guess is that he is referencing the colder air aloft arriving with the upper level storm system and being transported down to the surface with the precipitation...

The wind should switch from the north droping temps by 3-5 degress

12.1 inches is the 24 hour record on January 1964. I forgot what day.

[WeatherKing]

I'm really interested to see what happens when that possible convection moves over. That looks like it will be heavy

[WacoWx]

reporting stations just east of Comanche county reproting NULL and NA as precip types underneath this heavier band approaching the metroplex

The largest? I believe that was from a snowstorm in mid-February 1978 when 12.1 inches fell in a 24-hour period. (Edit: And it also appears the same amount fell from the storm alluded to by Ntxw back in January 1964.)

Found the Feb. 15, 1978 snow event at this link: http://www.srh.noaa.gov/fwd/?n=dfeb14

Here's some historical information about other memorable North Texas winter weather events. It's far from complete...it doesn't even mention the Feb. 15th record snow in Dallas in 1978!

http://www.srh.noaa.gov/fwd/?n=snowevents

So while this is bordering on impressive thus far, it's not historical by any means...not yet anyway.

In years past 2-4 inch snowfalls with occasional amounts of 3-5 inches happened a number of times. Now when you start talking about the 6-8 inch category, that becomes a bit more rare. And as for 10+ inches, that's only happened once or twice I think.

BTW, for what it's worth, back in early March 2007, we had an 8" snowfall and a 9" snowfall here in Grayson County...in one week!

The largest? I believe that was the Valentine's Day snowstorm in 1978 when 12.1 inches fell in a 24-hour period and it also appears the storm alluded to above back in January 1964.

It's not uncommon for 6-10" snows for areas along the red river and surrounding areas. It's tough getting a 3 inch total in the immediate DFW area especially the past 20 years or so. I don't think DFW has had a greater than 5 inch season in the past decade.

You should edit your profile here to put in your location. We can't tell where "in here" is.

True...we've had a fair number of 6+ inch events up here in the last 25 to 30 years that left only an inch or two in Dallas (even a couple of 5" sleet storms here).

And with recent mild winters and rapid urbanization producing a greater heat island effect in the Metroplex it does seem as if is getting harder to get a big, big snow in Big D...

12Z NAM predicts significant low-level warming over the Dallas-Ft. Worth Metroplex this afternoon with the freezing level rising to 10,000 ft. That would mean all rain after noon. 12Z GFS is almost in. Let's see what it says. NAM has been a bit warm of late.

Sigh I hope not, that would melt some of this snow!
