Good Evening from Port Lavaca!! Found yall via Storm2k a few months back. Been lurking, but finally decided to register.

Quick question. Where can I find weather archives for my area? I seem to remember my area being unseasonably warm, with a couple a days of thick seafog a few days before the foot of snow we got 12/04....which is the same kind of weather we had prior to FROPA. I would like to find out if my memory is correct.

Assuming the green is precipitation, what do the numbers translate to?

that ULL is going right across central Texas pulling up moisture from the GOM and EPAC....means plenty of moisture

Thank you for explaining!

Steve, I'm not sure what you are seeing bud. The second biggest snowfall on record is 4.4" in Feb. 1960. There is potential to break that with this storm at IAH.

Geopotential setup for 1960 snow event.


Also, it was not that cold.

Welcome to the forums. I am sure Ptarmigan can help you out with that question.

I looked at past snow events and many of them cam from ULL from the west, including the Februry 1895 snow event.

according to the water vapor image, where is this system that's bringing in all the moisture thurs and fri?

Diving into the base of the trough in the 4 Corners region. Folks, a very dynamic and interesting pattern developing for the next few days. You see our Pros and NWS is talking this up. In a normal situation, we would not see this frankness. Time for me to hit the hay. Thursday not far away. Welcome new folks and have fun. Nothing would make our buddy wxdata any happier...

Patricia let it develope. ...we are still 48-60hrs out....this will be cutoff ULL and associated trof. We will see it take shape tomorrow night IMO. Way to much model agreement.

A closed low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current. Cutoff lows may remain nearly stationary for days, or on occasion may move westward opposite to the prevailing flow aloft (ie, retrogression).
