Winter Weather/Extreme Cold Threat 1/13-1/17

[wx_guy]

Observed sounding from BMX last hour pretty much dashes any hopes of snow. While it's dropping into the 30s at the surface, it's still 47-48 degrees higher up.




This is shown to a much more extreme level at Jackson, MS, where it's 25 at the surface but about 20 degrees warmer just higher up. So rain falls and freezes.

I’m in Tuscaloosa county and it’s doing something outside. Sounds like sprinkles? Our streetlights suck. Either way something precipitation wise is happening. According to my phone the temp is 33

Just had a pretty decent burst of mixed precip. It seemed to be mostly sleet with freezing rain mixed in. We've got layers of ice on vehicles and the front porch. The road in front of the house is just wet at the moment, but the driveway is starting to form ice.

We had sleet too. First time today it's sleeted here. Everything else has been frozen rain.

Thankfully the RAP and HRRR totals have come down. But they're both not handling initializing well, not sure what impact that'll have but, either way it'll be slick I imagine for a lot of areas

The obs from the NWS called it flurries at the time. I found that interesting.

 

[MikeP]

Just took my dog out. Could swear I had flurries.

Edit: Still sitting at 36 here....

We are getting what I would call grauple presently in McCalla/Bessemer

 

[TileDude]

Just sent the pup out to do her business. She came back in with a damp coat. Guess that is one way to check if precip is falling

 

[wx_guy]

The 0z RAP initialized better, and it's back to painting an icy time of things!

 

[UncleJuJu98]

Man the HRRR is doing a very bad job at telling what's currently going on. Precip is a lot heavier in the now cast

 

[UncleJuJu98]

Drizzling at my house. My wife's car is wet not frozen though so it's still got a little bit to go.

32 at my parents house in pinson. And 30 here

Just as an fyi, with those temps your wet bulb is probably closer to 33. If I'm not mistaken it's about a 2:1 ratio as in for every degree the temp drops with cooling, the dew point rises 2.

 

[UncleJuJu98]

Temp is plummeting here. Those surface temps will be freezing very soon.

Down to 29 here with light sprinkles. If we get in the heavier precip it won’t take long to ice over. Hearing reports of icing as close as the Corner and Sumiton areas now.

Yeah those showers are pretty heavy just northwest of here that'll be filling in here. If that sits over one area for 6 hours even remotely the same intensity it'll be some difficult travelling

I-22 closed now in Walker County to go with 65 in Cullman.
