Galveston Bay won't freeze over. The current water temp has to be 55°F to 60°F. Temps would have to be majority below 32°F for minimum 6 weeks to drop that water to freezing

If that temp is true, yeah, not gonna freeze. Lol. I mean the Long Island sound barely freezes and that's up here while water temps are in the 30s/40s in December and nights get into the 20s.

But if the air drops below 15° there it will definitely cool off the water surface a lot. I would say 2 weeks of below 15° and the Bay would start to see frozen spots

Even that won't happen. Galveston is Zone 10A, two weeks of 15°F temps would be unheard of

Looked up the forecast for Allen, TX where I used to live and holy crap.
Gonna be in the mid 30s today tomorrow and Friday but then it gets worse.
High 25 Saturday, 29 Sunday and then a high of just 19 for next Monday! The last time KDAL had a sub 20 high was in 1990. It is not common at all. Typical is maybe 30 for the coldest high.

Low of 7. That's coldest and first <10 low since 1996 (8) for KDFW. KDAL hasn't seen <10 since 1989. That is some insane cold.

For comparison, in KPDK's 20+ year history the coldest high has been 24 so had to check out KATL. Their last sub 20 high was 18 back in 1996. Dating back to 1929, KATL has only had a sub 20 in 7 years (and it looks like it only happened 7 times so just once each of those years).

Meanwhile for here gonna be a nice day. 66-67 forecast and clear so far today. Low 60s again tomorrow before our cool down but nothing like Dallas.
5 days in a row with highs in the upper 40s. Supposedly a lot of rain/cloud cover. Not even supposed to get below freezing til maybe end of next week with a low of 29.
11-15 day forecast is finally looking like it's trying to warm up to more seasonable temps and actually look like late winter/very early spring. Mostly upper 50s/near 60 for highs. Around 40 for lows.

I can see a tree out my window that has some buds trying to come out. If we had a 70+ high it might actually start its leaf out. I've been annoyed at the lack of 70s this winter. To not get a single 70 in Dec, Jan, or Feb is just crazy. But at this point maybe it's a good thing. Need to make it through this stretch without a deep freeze and we'll be on our way to Spring in just a few weeks. But if it does happen, at least nothing is starting too early like last year.

Right. Would be interesting to see but not happening. There would have to be some massive blocking in the Southeast/Atlantic for that to happen where the cold air just sits over Texas and gets reinforced by another shot from the north. The Polar Vortex would have to drop into the plains. I dont think I ever heard of that happening.

That Fort Worther who often brags about how warm it is (forgot his name) has to be sh*ting his pants right about now. Holy crap, lol.

Lol are you referring to me?, it certainly isn’t warm or even mild today here and there is no even remotely mild weather in the offing for the foreseeable future per the weather channel’s extended forecast. If anything the weather forecast has gotten colder for Fort Worth and for much of Texas for that matter; some places north of DFW could see lows near zero by late this weekend, and I thought I left this kind of continental rubbish behind when I left Indiana

I think in Texas you pretty much need to be down near the Gulf to be safe from these Arctic air intrusions. Even Austin can get the occasional cold burst.

If the GFS is correct, even the northern Gulf might not be safe. The SE from Alabama beyond gets lucky with the placement of the ridge.
