5:45 Northwest Arkansas Update
January 31, 2008

The heavy snow has cleared the majority of NE OK and NW AR. Light snow is still expected across Washington and Madison counties through 6:30 p.m. Most of the snow through 7 p.m. will be confined across the Arkansas I-40 corridor; however, light snow flurries can’t be ruled out this evening. Travel may become an issue tonight as the roads freeze. Overnight lows are expected to drop into the lower 20s, so use caution.

5:45 River Valley Update
January 31, 2008

Heavy snow continues to fall across the River Valley. The snow has been very wet, and large flakes have been reported all across the area. These large flakes are accumulating quickly, so don’t be surprised to see 1 to 2 inches of snow when the snow ends. We’ll expect the heavy snow to taper off to flurries around 6:30. Fortunately, the temperatures are sitting around 33 degrees, so the roads are remaining relatively clear.

Overnight lows will fall into the 20’s, so a freeze will be expected overnight.

River Valley Snow
January 31, 2008

Van Buren, AR is now seeing snow as temperatures continue to fall. Many areas along the I-40 corridor are just now going over to a mix of wet snow and rain. This line will continue to push southward as we move into the evening. Additional cooling is now taking place due to evaporational cooling effects with the onset of a heavy batch of precipitation along with more cold air funneling in on the back side of the Low.

Note the circulation of the surface Low as depicted from the wind barbs. The center is now just south of the River Valley over SE OK. As more cold air continues to funnel into our area most locations will see precipitation on the frozen side of the spectrum.

Road conditions will be going downhill as we move into the overnight period! Slush and wet roadways will turn to ice and present a great threat to travel. Please remember to give yourself at least a “four second” distance between yourself and the car in front of you. Anticipate slick road conditions by giving yourself ample room to stop.

What an active weather day it has been across the entire area. From rain and snow to sleet and hail we have had it all. I actually heard a few rumbles of thunder near Ozark as the heaviest sleet moved through earlier this morning. Here are a few pictures from Northern Franklin county where most places have at least half a inch of total accumulation from freezing rain, sleet, and snow (as of mid-afternoon).

I am sure I am not the only one to notice how worked up the birds were today. This Northern Flicker was just about psychotic looking in its continuous quest to find food before the ground was covered with ice.

About .20 of freezing rain accumulation on telephone lines from early morning freezing rain and freezing drizzle during the afternoon

Here is what the county roads look like in Northern Franklin county. The combination of sleet and freezing rain/drizzle has made many secondary/county roads across the Ozarks pretty slick.

2:00 P.M. Update
January 31, 2008

The dry slot that pushed throughout the area has moved east; more snow will be possible throughout the rest of the afternoon and evening, especially north of I-40.

Temperatures aloft are starting to cool as the back edge of the low moves through, which will turn the rain/drizzle back over to sleet and snow. Travel conditions across NW AR will continue to deteriorate this evening. Northern Benton, Carroll, and Delaware counties have received in upwards of 3 to 4 inches of snow already, and an additional 2 inches will be possible across northwest Arkansas and northeastern Oklahoma through the evening.

We’ll expect a dusting to an inch of snow across the River Valley this afternoon. Totals will not be as high due to some of the warm air aloft that has kept the precipitation liquid throughout the morning.

The snow should taper off to flurries around 10 p.m. tonight.

WINTER WEATHER UPDATE
January 31, 2008

Winter weather has already started to take place across the area this morning. Most of the viewing region is currently above freezing, but some areas in NW Arkansas are right at the freezing mark and are getting some sleet and even some light snow. The main energy with this system has not arrived yet and it looks like this upper level low is going to track further south than what was anticipated. That means snow totals could be higher. I will have our updated snowfall forecast coming up in a few minutes.

Latest Snow Forecast
January 31, 2008

The latest computer model runs have continued to paint the heaviest snow totals across NE OK and NW AR for this particular event. The NAM is very robust with snow totals; however, the GFS is still holding more of a lighter scenario, so I’m taking the middle of the road at this point. Back toward I-44 there is the potential for
6+ inches of snow. Northern Benton and Delaware counties will likely see the highest totals in our area due to their proximity to the cold air.

If this system pulls a little further south, the potentail for higher totals will exist, especially across the River Valley. Travel throughout Thursday afternoon may become dangerous with the snow on the roadways. We’ll keep you posted.

UPDATED FORECAST…
January 30, 2008


Here are the most recent weather models for the possible snow accumulation across the area. The GFS and NAM models differ. The first picture you see on the screen is the NAM weather model forecast for 48 hours out. You can see the snow chances for NE OK, NW AR and SW MO. The next weather model that you see is the GFS forecast for 48 hours out. This weather model is showing a little bit higher precipitation chances and the precipitation covering a larger area. The one weather variable that these weather models are forecasting will be the snow for NE OK, NW AR and SW MO. Keep checking the 4029 weather blog, the most detailed weather blog in the area, for all the latest weather information. Also, watch Chief Meteorologist Drew Michaels’ weather forecast tonight at 5, 6, and 10pm. He will have the very latest weather information.
