January: Calmer Pattern To End The Month

[MontgomeryCoWx]

So when is it suppose to start for hou and surrounding areas? Some mets say 9( billingsly,heller) David Paul says 12-2

I got to think before midnight. I'm almost at freezing and have ice pellets

MOCOWX, so the event has already unfolded for you then. SHARE. NOW.

[nuby3]

My guess is all of Montgomery county is below freezing by 8 or 9pm. IAH by 9 or 10. I-10 by 10 or 11.

Update from Jeff:

Things starting to go downhill.

Freezing line has breached our northern counties with Caldwell now at 32 and CLL at 35. TXDOT is showing ice formation on roadways just outside our region mainly along and north of HWY 190 from Hearne to Round Rock. Appears another surge of cold/dry air is moving into the region and this should push much of the area to freezing in the midnight to 300am period.

A review of roadway versus air temperatures shows roadway bridges running about 3 degrees higher than air temperatures indicating critical air temperature for ice formation on bridges will be in the 29-30 degree range. This is currently fairly uniform across the entire region…but the difference is starting to close NW of Harris County where the air has been colder longer cooling those bridges.

See now reason to change any accumulation and P-type forms at this time.

Travel will be extremely hazardous after midnight tonight for most areas and all areas by 300am. Avoid travel unless it is an emergency.

Not sure if/when we will rise above freezing on Friday. Some of the models are attempting to hang on to sub-32F temperatures until the early to mid afternoon hours….much will depend on how quickly the precipitation ends. Still expect roadways to be a big problem for a good part of Friday.

Next update will be between 10-11pm.

Bush at 36.8. Rain. Wind...NNE at 23 MPH. Fun.

[Katdaddy]

41F in League City with low clouds blasting across the sky from the NE and some light mist. The fun and games have started.

[jasons2k]

Here, it's 34.9, falling at a rate of 1.1 degrees per hour.

Winds out of the NNE at 26mph with a wind chill of 25.

Don't see that too often.

Heavy IP at HWY 6 and OSR

Jeff, when is the changeover expected to occur in CLL? Still 35 and just rain here. Haven't seen any sleet yet.

[srainhoutx]

Heavy sleet in Caldwell

[djmike]

Not sure how accurate my weatherbug in my area is, but according to it we just hit 32 here in Beaumont!

[HouTXmetro]

Does it look like our coastal low will still take shape? Most of the precip is north and east of Houston and I don't see much coming from the SW just yet. Watching the State radar closely.

[cperk]

Is it possible to get a mix at 37 degrees because I think we are.

It is going to bounce all around all night between ZR/IP/SN

yes

[djjordan]

Haven't seen this many people on the board in quite awhile. Gonna be a cold, slippery, interesting night to say the least.

You don't think there will be a changeover to mainly sleet/snow? I am hoping for at least .50 inch of sleet/snow tonight.

Looking at the radar on intellicast we are getting lite rain in the southwest and I can verify that.

From Portastorm at S2K...

Things are going downhill fast in Austin...

And ice on the US Hwy 183/Toll Road 45 flyover here in town has caused a bad wreck. Yeah, this is just the beginning.

[MontgomeryCoWx]

I can't get a good pic but it's coming down hard now. Definitely a mix of hey rain/sleet
