DFWWeather Posted February 19 Share Posted February 19 On 2/4/2025 at 7:55 AM, Stx_Thunder said: Not seeing any strong signal for another Arctic air intrusion or outbreak in the state for the rest of the season. The next few frontal airmass intrusions are mostly just Canadian origin with the real cold air firmly staying north/east. -AO does not always translate to Arctic air intrusion nor outbreak (even during winter). I apologize if I have upset you, but you absolutely did say no more Arctic air for the rest of the season. See your post above from Feb 4th. All I did was disagree with you. I use the word 'extreme' because that is the term the NWS uses. The Extreme Cold Warning is not just for wind chills, it is also issued for the prolonged duration of subfreezing temps, and the threat of temps falling to 10 or lower or for high temps failing to reach 20. For our area, the latter is considered severe cold. In this case, there is a threat some areas around the DFW Metroplex will get to the single digits with this and for a prolonged duration subfreezing temperatures, not to mention wind chills as cold as 10 below zero. I was just pointing out that not even South Texas is escaping the cold. Anytime it freezes in LRGV it is a big deal. That is why Marshall J. McFarland came up with the McFarland signature that recognized prominent 500mb pattern features that lead up to freezes deep into Texas. The key to getting Texas cold is the position of the west coast ridge, if it is along the west coast, or off-shore up over Alaska. The latter has historically produced some of Texas' biggest cold shots and is a key element in the McFarland pattern. Though the current outbreak was not a result of a McFarland.

aggiegeog Posted February 19 Share Posted February 19 Widespread flurries across the N half of the state today. Areas south of favored lakes could see a couple inches otherwise just flurries and mist. Temps across N and NE TX will max out in the mid 20s with continued flurries. Tonight will clear out and wind will die down allowing temps to fall into the 5-15 range and some near the Red River that get snow today may go sub 0 tonight. Many will stay below freezing tomorrow and a few may stay below freezing Friday also. Link to comment Share on other sites More sharing options...
TXHawk88 Posted February 19 Share Posted February 19 It’s not much but I’ll take it, having snow flurries fly around makes this cold a lot more enjoyable. 2 years in a row of pretty decent lake effect snow. Link to comment Share on other sites More sharing options...
gwlee7 Posted February 19 Share Posted February 19 When I saw it flurrying, I had not considered lake effect snow. I now know that if covering enough surface area, man made lakes can give us a little eye candy. Link to comment Share on other sites More sharing options...

Again, taking words right out of my mouth on here for obvious reasons.. Like I already said in my last post, if you had just kept to what you actually wanted to say about the cold (instead of coming back to "correct" me again & again), everything would've literally been fine in here. It's just common sense and etiquette. Nothing complicated about this. Link to comment Share on other sites More sharing options...
aggiegeog Posted February 20 Share Posted February 20 For Tyler, 2025 could well show up in the record book the same number of times as 2021 between record lows and record low high. 2021 had 5. 2025 has a legit shot at 5 from this event. Today's record low high was 31 and we had a high of 24. It is already down to 18 so tomorrow's record low of 19 will fall at midnight. Tomorrow's record low high is 36, that likely also falls. Friday's records of 19 and 35 will be close but are attainable. Today was also the latest ever sub 26 high. Basically this event is only rivaled by 1978 and 2021 for cold outbreaks around this time period of the 3rd week of Feb. Link to comment Share on other sites More sharing options...
aggiegeog Posted February 21 Share Posted February 21 Another near freezing highs day. Lindale is getting some flurries this afternoon from the band along I20 across E TX. Link to comment Share on other sites More sharing options...

Stx_Thunder Posted February 22 Author Share Posted February 22 'Meant to post this last night after looking at latest evening model data, but with the modification process of the (extremely shallow) arctic origin airmass well underway just above it in the LLs around the coast, elevated storms have broken out today around Houston with some already stronger lightning strikes as of typing this. Corpus (CRP) 12z upper air obs this morning already showing effective shear near 60 knots, and steep ML lapse rates above 7 C. Fairly strong LL south warm-air advection flow, and cold H5 temps below -15 C. Even though SPC is thinking the hail threat is lower today & tonight on D1 outlook discussion (probably because of latest mesoscale model data this morning keeping everything offshore), the models are underdoing the deep convective threat today, onshore. Especially the already ongoing Houston area storms. So I don't think the severe hail potential is nonexistent. Especially tonight as Euro has been fairly consistent showing a decent amount of MUCAPE (>500) hanging over the mid-upper coastal region with weakening CIN. Ahead of a stronger, more pronounced H7 shortwave moving into the state from the west (both on Euro & GFS). Link to comment Share on other sites More sharing options...
Powerball Posted February 26 Share Posted February 26 For the first time since 2/8, DFW exceeded 80*F with an official high of 81*F toxay. Link to comment Share on other sites More sharing options...
Powerball Posted March 1 Share Posted March 1 The last few days took a massive bite out of the monthly departure for DFW, as February will only end up -1.2*F below average. As far as winter on the whole (Dec - Feb), it ends up with an average temp of 48.6*F (+0.3*F above average). Snowfall-wise, the season (Dec - Feb) ended up being above average with a total of 2.6", all of which fell with the Winter Storm on 1/9 (and was partially sleet contaminated).

Stx_Thunder Posted March 4 Author Share Posted March 4 Very impressive dew point drops behind today's system & dryline to < 0 F in the Rio Grande plains and even < 10 F near the coastal bend with very warm & strong post-frontal westerly downslope flow component (Cotulla is sitting at -4 F right now at 3 pm obs). Del Rio had post-frontal wind gusts to 60 mph earlier also. The wind is howling this afternoon in the southern half of state with all the very warm afternoon air transferring more of all this post-frontal momentum aloft down to the surface. DP was at 0 F in El Paso yesterday afternoon with blowing dust in W/NWTX. I can see the dust is around here in STX causing haze this afternoon but that could also be because of an active wildfire ongoing in Duval county blowing the smoke east. No disagreement at all on SPC's decision yesterday to post a rare 'Extreme' fire risk outlook area over the southwestern half of state for today. Considering how dry both the air & ground are in that region (along with the warm, strong west downslope flow). Although no major active wildfires have broken out looking at TX wildfire map data as of typing this. Link to comment Share on other sites More sharing options...
Stx_Thunder Posted March 5 Author Share Posted March 5 A large brushfire (Welder Complex) burned just over 1500 acres total in San Patricio county on the northeast side of Sinton where evacuations of several hundred people occurred Tuesday afternoon (biggest town in the county outside of Corpus area). It seems to be fully contained now late tonight looking at local media updates from Tuesday evening. Especially now that winds have died off and DPs have recovered, but did burn structures down (20 houses but damage extent still not clear). This was the largest active fire reported in the state on Tuesday. - - - Mesonet site in Val Verde county (Del Rio area) around noon Tuesday reported 67 mph post-frontal wind gust. Highest non-convective gust recorded in the Austin/SAT NWS region on latest LSR data. Link to comment Share on other sites More sharing options...
Stx_Thunder Posted Sunday at 01:43 PM Author Share Posted Sunday at 01:43 PM https://www.kristv.com/news/local-news/in-your-neighborhood/san-patricio-county/sinton/sinton-fires-investigators-determine-what-started-tuesdays-devastating-fires https://www.kristv.com/news/local-news/in-your-neighborhood/san-patricio-county/sinton/sinton-neighbors-return-to-the-aftermath-of-the-devastating-fires - Recap of Tuesday's wildfire aftermath in Sinton. Multiple wildfires started in San Patricio county Tuesday afternoon. Which is likely why the A&M fire incident data was overestimating the burn acreage of the 'Welder' fire alone. Although another fire (Railway) not far from it on the northeast outskirts of Sinton did burn over 700 acres total. ArcGIS data also shows this. Despite its confirmed small size (<100 acres), all it took for the Welder fire to become disastrous & completely burn down 17 homes in Sinton, was a simple downed power line. Combined with strong post-frontal winds, extremely dry air (DP around 10 F), ongoing drought/cured vegetation fuels, and very warm temps in the 80s/90s last Tuesday afternoon. - - - The fire wx danger over the western half of state does not look to end anytime very soon. SPC is already highlighting Critical fire wx risk areas in the D 4-8 outlook as the fire threat could really escalate again behind another deep Low traversing the Plains at the end of this new week (14th - 15th). And may even need to be expanded further northeast closer to DFW region and into the C Plains. https://www.spc.noaa.gov/products/exper/fire_wx/ - Also, the ongoing drought in the state is obviously worsening with San Antonio area now in a developing 'Exceptional' (D4; max drought intensity) status. https://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?South Link to comment Share on other sites More sharing options...
