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

Down to 37 at my parents house. Was 44 at 1:40.

Well the newest hrrr run. Has it worst than what it's had all day for i20 lol. Pretty much a quart of inch along the interstate.

Id say we may need a extension of the winter storm

Surprised we haven’t seen it yet. The short term models have been very consistent today, yet BMX has stayed conservative, suggesting only “light” bridge/overpass icing in Central Alabama.

Down to 33 now. Dropped 3 in the last hour.

 

[TileDude]

I would say the freezing line is entering Jefferson county now

 

[UncleJuJu98]

Here's the HRRR. Check out the slow down and precip expanding on the backside.

Is clearing skies a bad thing? Down 39 now.

Will allow temps to cool quicker if skies clear but really doesn't matter now as arctic front is now bearing down

 

[TileDude]

That would seem to show 6 to 8 hours of possible freezing rain north of I-20

Interesting look. The SPC Mesoanalysis here is predicting any precipitation that might fall on the latest RAP. Outside of eastern TN, *it's almost all freezing rain and sleet* everywhere else...and given the latest HRRR, it looks like that will continue...

I’ve never experienced sleet like this. Been ongoing for about an hour. Located in Hazel Green AL.

be thankful that it's sleet and not freezing rain!

 

[StormStalker]

HUN is forecasting my low tomorrow night of -4. Still have off and on again sleet showers ongoing.

 

[UncleJuJu98]

Nws of Birmingham updated they're graphics. But no winter storm warning. even

 

[JPWX]

Meanwhile, there's only a 5 degree temperature difference between Holly Springs, MS (11) and North Pole, Alaska (6)

 

[TileDude]

They did expand the elevated area south.

 

[MichelleH]

Yeah, I got the alert on my phone and jumped lol. Closed due to icy conditions and multiple crashes.

 

[TileDude]

Included in the BMX update.

I believe they held in the WSW because the nam and gfs show much less..like .05 of zr in Bham, the hrrr is an outlier.

 

[AL_ham_op]

I'm going to have to agree with BMX. It's still in the 40s around Bham. Just doesn't seem like the temps will get low enough fast enough to cool things before the rain gets here.

Probably about that time to forget models and watch radar trends. I just hit 32 so the freezing line is advancing south.
