There is no exact science to the lines drawn on the snowfall map below…

 

This is just to give you a general idea of what kind of snowfall accumulations are expected – as well as what areas are expected to receive the higher snowfall amounts.

 

It looks like Arkansas will take the brunt of this storm tomorrow with up to a foot expected there, however it will begin weakening as it approaches our area. This is why you see the 4″ amounts in North Mississippi tapering off as you get closer to Alabama.

 

Will update the map if needed later tonight or on Wednesday.

The National Weather Service in Huntsville has issued a Winter Storm Watch for all counties in North Alabama from Wednesday evening through Wednesday night.

 

As an area of low pressure moves along the Gulf coast, it will spread moisture into the area Wednesday evening, bringing periods of snow through Wednesday night.

 

Snow will have ended by Wednesday morning.

 

At this time, total snow accumulations are expected to be around 2 inches across most of the area. There could be some a little higher amounts locally.

 

Roads – especially bridges and overpasses – will likely become slick, especially those left untreated.

 

WINTER STORM WATCH: A Winter Storm Watch means that winter weather conditions are expected within 36 to 48 hours. In our area it indicates either at least 2″ of snow will fall or a quarter inch of ice accumulation (In this case it’s 2″ of snow). A Watch is upgraded to a Warning when the event is within 24 hours and confidence in the forecast is high enough to warrant.

 

CENTRAL ALABAMA: A Winter Storm Watch is also in effect for the Central Alabama counties from the NWS in Birmingham. That includes places like Tuscaloosa, Birmingham, Anniston, and Sylacauga.

A historic blizzard is impacting the Midwest this morning with heavy snow, freezing rain, sleet, frigid temperatures, and very strong winds. Wind chill values well below zero across much of the region.

 

The low pressure center is located over eastern Texas right now, and on the south side of the low severe weather is ongoing across much of Louisiana this morning with a Tornado Watch posted, along with a few warnings.

 

However, on the northern side a Blizzard Warning is in effect from Oklahoma City all the way through Central Missouri through Chicago to Detroit.

 

Snowfall amounts between one and two FEET are expected across a large swath of the Midwest. There will also be an area further south of mixed precipitation where up to a half inch or so of freezing rain is expected which could cause major power outages. Wind chill values could drop to as low as -40 to -50 in some areas.

 

Below are a few observations at 9:00am from around the Midwest…

 

OKLAHOMA…
Oklahoma City, Heavy Snow, temp 9, wind NW 40 G 47, wind chill -16, visibility 1/4 mile
Norman, Snow, temp 10, wind NW 25 G 38, wind chill -10, visibility 1/2 mile
Tulsa, Heavy Snow, temp 12, wind NW 24 G 31, wind chill -8, visibility 1/4 mile

 

ARKANSAS…
Fayetteville, Light snow, temp 26, wind NW 15 G 24, wind chill 14, visibility 3/4 mile
Harrison, Freezing rain, temp 31, wind NE 15 G 22, wind chill 20
Hot Springs, Thunderstorm, temp 55, wind E 10

 

MISSOURI…

On the south end of the storm system, much different weather conditions over Louisiana, where severe thunderstorms will occur today…

The National Weather Service in Huntsville has issued a Winter Storm Watch for all of North Alabama from late Tuesday night until early Wednesday morning.

 

Precipitation will move into the area on Tuesday, but for the day Tuesday it will be ALL rain, will not see a changeover to snow until Tuesday night.

 

At this time it appears the best window for snowfall, which could be heavy at times in some areas – will be between Midnight Tuesday Night and 9:00am Wednesday morning.

 

Generally, expecting snowfall accumulations 2-4 inches. However, there could be a narrow band of higher amounts where the “deformation zone” develops on the back side of the system. One thing to note, the snow will be wet, heavy snow – so there could be some problems with limbs going down and possibly knocking out power in areas that see the heaviest snow.

 

Upper level lows are notoriously difficult to predict – and there will probably be some surprises when it is all said and done.

 

Where the heaviest snow falls, roads may become snow covered and hazardous for a few hours Wednesday morning – however temperatures will rise above freezing Wednesday afternoon – hopefully that will help with road conditions. Any snow that falls will be gone rather quickly as we will reach 50 degrees over the next several days.

 

Below is a look at a map indicating the areas with the HIGHEST probability of seeing significant snowfall. Also areas in the pink shading will see the highest chance of being affect by the deformation zone – where very heavy snow could fall, possibly even some thunder at times. Not everyone is going to see a lot of snow – those away from the track of the upper low will see much lower snow amounts. (Click for a larger image)

A developing area of low pressure in the Gulf of Mexico and associated upper level low will bring the chance for rain to change to snow late Tuesday into Tuesday night as the low center passes to our south and east.

 

Exact snowfall amounts are highly dependent on the exact track of the of the low pressure center and associated upper level low along with other factors such as an area of high pressure to our north.

 

However, the potential is definitely there for a significant snowfall event across at least parts of North Alabama. Chances may be a bit higher north of Highway 278 in North Alabama.

 

If colder air were already in place – this would have the potential to be a much more significant event – but temperatures on Tuesday could reach well into the 40s – limiting precipitation early on to just rain.

 

Here is a map of the probability of 4 inches or more of snowfall from 6am Tuesday to 6am Wednesday. This is from National Weather Service’s Hydrometeorological Prediction Center (HPC), click for a larger image:

 

 

That map indicates about a 40% probability of at least 4 inches of snow for a good part of North Alabama, especially areas from the Shoals to Huntsville/Decatur to Scottsboro.

 

Still a great deal of uncertainty in this forecast – hopefully by later today or on Monday there will be a better indication of what kind of specefic accumulations we can expect.

Generally very light snow accumulations occurred on Thursday night across North Alabama. The highest totals were found in Tennessee and areas near the Tennessee/Alabama state line.

 

Amounts tapered off quickly as you travel south of the Tennessee River – and as I type this afternoon, most of the snow has already been melted by the sunshine we’ve seen all day.

 

But here is quick look at a map of some of the totals across the region (click for full size image):

Temperatures across northern Minnesota this morning were as cold as -46°F at International Falls and Babbit, Minnesota.

 

That was the 5th coldest temperature on record at International Falls – the all time record low is -55°F on January 6, 1909.

 

Thankfully, although colder air has moved into the North Alabama area – we won’t see a direct impact by this same air mass, just a glancing blow.

A low pressure system will develop in the northern Gulf of Mexico and bring widespread precipitation to the area late Sunday into Sunday night, lasting through much of the day Monday. Additionally, scattered snow showers will be possible through Tuesday as well.

 

Computer models have converged on a forecast that indicates significant accumulations across all of North Alabama.

 

Precipitation could start off as a period of brief sleet, but will quickly change over to all snow. The snow could be heavy at times in some of the snow bands.

 

Snowfall amounts will vary over short distances. Some areas receiving over 6 inches of accumulation is not out of the question.

 

Snow will begin falling late Sunday afternoon (again possibly beginning briefly as sleet). The most significant snowfall will occur after midnight Sunday night into Monday morning.

 

If the expected snowfall accumulations become reality, travel will become a real problem all across North Alabama as roads could likely become snow covered – especially during periods of heavy snow.

 

Areas to the south of the Cullman area may also have to deal with some freezing rain at times – still the possibility for an ice storm threat in the Central Alabama area.

 

Check back for more updates on this storm system. The exact details and more precise accumulation amounts will become more clear tomorrow, as we move a bit closer to the event.
