Radars really starting to go with strong lift approaching

[hlewis]

Whats the update hlewis? Radar indicating precip in your area

friend on facebook said it's falling in Hiljie, but she isn't sure if it's sleet or snow lol that's 5 or so minutes south on 59 from El Campo. i think i said 15 minutes earlier... just right outside El Campo.

What is the minimum dB for the moisture to reach the ground? Looks like we've got some 10dB right above us in Missouri City, but it's dry as dust out here...

[txsnowmaker]

Is the effect of falling frozen precip strong enough to send surface temps from 35F to freezing or below freezing?

[Katdaddy]

Agree with Jeff. Upper level low still digging S of the Big Bend with strong moisture feed across coastal areas. Hou-Gal radar lighting up to the SW of Houston area.

Anyone that is around 1960, Cypress, Fairfield or Waller..Let me know when you start seeing something. We are waiting here checking outside every 20 minutes or so...LOL

yes, NWS mentioned the possibility of evaporative cooling once the precip starts falling (they said these could be 5-7 degree drops)

[jeff]

Numerous roads going impassable over S TX with ZR. Numeorus accidents and 1 fatal.

Veterans Memorial Bridge in Jefferson County closed by TXDOT due to ice...sanding operations in progress

When looking at the radar on NWS which should I look at "base" or "Composite" because according to composite I should have precip here but we don't.

yes....the dewpoint and surface temps will meet in the middle....mostly likely around 27-28F for most...

[jeff]

50% of Raymondville TX now without power due to icing

[hlewis]

very light light drizzle in Louise

It is working to moisten the low levels...give it a few hours.

Do you mind explaining to this very much so amateur what that means for us at the coast and our neighbors inland?

[TXStormjg]

Hwy 290....Roberts Rd area....small flakes falling. Now waiting on the "event"

[indian1999]

groves, tx city officials sent a phone recording out a few minutes ago saying for everyone in the city to stay off the roads cause there is a possibility of 1/4 inch of ice tonight...could that really be possible for this area?

[Paul]

Pearland had a leak in a fuel cell...launch has been delayed... ...whatever passed over us is gone now....holding at 33 surface with 23dew....I do have some houses on the street who have ice pellets I am guessing on the roofs....not much now though...

[TexasMetBlake]

Keep an eye on your PM's folks...

[wxman57]

Radar echoes are on the increase to our southwest in Ft. Bend County. Good sign that we'll see something tonight. I'm heading to bed soon, though. Hope you all see something tonight. I can wait until morning.

I still have light flurries here. No change in intensity or size, but they are still here.
