gwlee7 Posted February 1, 2023 Share Posted February 1, 2023 Usually during winter weather I enjoy the snow and even the sleet. Today I am hoping to get dry slotted in my little corner of DFW. 1 Link to comment Share on other sites More sharing options...

From the looks of it, seems like a pretty serious event there. Luckily since temps seemed to be around 30-31 when the rain was falling and it was heavy, some definitely ran off instead of freeze (when temps are in the 20s instead much more freezes on the ground) but as a city not used to serious winter weather I’m sure it’s a major impact. 1 Link to comment Share on other sites More sharing options...

weatherextreme Posted February 1, 2023 Share Posted February 1, 2023 Lots of reports that radar is showing freezing rain, but nothing hitting the ground. Do we know what's causing that and could it change ? 1 Link to comment Share on other sites More sharing options...

Do we know what's causing that and could it change ? Dry layer producing evaporation, aka virga? Not what I've been reading, there are areas of freezing mist/drizzle that radar is not detecting.

That would also tend to keep temperatures below freezing if there is rain evaporating into it Link to comment Share on other sites More sharing options...
gwlee7 Posted February 1, 2023 Share Posted February 1, 2023 Dry slot is holding here at my house. Nothing hitting the ground. I am about where Coppell, Flower Mound, and Lewisville city limits touch together. Just west of 35. Link to comment Share on other sites More sharing options...

weatherextreme Posted February 1, 2023 Share Posted February 1, 2023 Mesoscale Discussion 0123 NWS Storm Prediction Center Norman OK 1135 AM CST Wed Feb 01 2023 Areas affected...north-central Texas...northwest Texas...and portions of Southwest Texas Concerning...Freezing rain Valid 011735Z - 012130Z SUMMARY...Light to moderate freezing rain will persist into the afternoon from north-central Texas to near Abilene and east of Midland. DISCUSSION...A band of relatively concentrated precipitation has developed from west of San Angelo to northern Texas. This is forming in a zone of weak frontogenesis and warm air advection around 700mb. This will favor heavier precipitation rates in this corridor through the afternoon. The heaviest rates are expected by late afternoon as frontogenesis strengthens and focuses in this region. The last several HRRR runs suggest a mesoscale corridor of total QPF in excess of 0.75 inches. Observations this morning have shown a mix of sleet and freezing rain, but this is expected to transition to mostly freezing rain this afternoon as the cold air becomes more shallow. Icing is expected across most of this region with more significant icing possible where any banding can develop later this afternoon/evening.

weatherextreme Posted February 1, 2023 Share Posted February 1, 2023 Big blob showing up on radar out in West Texas. If that is heading to DFW that could be some bad news later on. 1 Link to comment Share on other sites More sharing options...

Do we know what's causing that and could it change ? Some drier air did move in since yesterday's round. Dewpoints were in the mid/upper teens this morning. The column is gradually moistening again, but the precipitaiton rates are lighter and the better forcing appears to be higher up in the atmosphere, so it's going to take a bit of extra time for the entire column to become saturated.

The thing to be concerned about headed into tonight is even if air temps do eventually warm to 32-33*F, you can still see a decent amount of ice accretion if the surface temperature on objects remain below freezing. Since DFW has been in the 20s since late Sunday evening (over 60 hours), that may certainly end up be the case. Not to mention, the roads/sidewalks have already been primed for efficient accretion with the layer of sleet from yesterday. 1 Link to comment Share on other sites More sharing options...

But I wonder why there seems a lot of melting underway. I see the streets are clearing up and nothing really stick on trees or power lines here, which is really good. Maybe the actual accumulation could be less than expected Link to comment Share on other sites More sharing options...

Maybe the actual accumulation could be less than expected TxDOT, NTTA and local municipalities have been doing some treatment on the highways and main thoroughfares. The secondary roads and side streets are still skating rinks. Link to comment Share on other sites More sharing options...
Ed, snow and hurricane fan Posted February 1, 2023 Share Posted February 1, 2023 There is some insolation even under cloudy skies, I'd think dark road surfaces might warm enough to melt snow even just below freezing. 1 Link to comment Share on other sites More sharing options...
