Not Alot Going on… Next Week May be Different

gfs384-weasdsfc--conus-312-C-newaccusnowcover (2)

DEEP SOUTH SNOWFALL! That is a sentence that everyone down here loves to hear! They could be hearing it very soon. The models have been hinting at snowfall for the south and southeast in the past week or so. It’s exciting to think that just a month ago we thought it’d be warm at this time but an arctic blast is forcing itself through. Much of the country will be gripped by extremely cold air the next couple of weeks. And what happens when cold air and precipitation collide? White stuff falls from the sky. The white stuff everyone wants to see… snow! It will snow, folks, and there will be a lot of it. Timing and exact location of the storm is currently unknown at this time. But right now we are looking at around the 17th a major snowstorm for the Tennessee Valley and northern Georgia, Mississippi, and Alabama. Before that a few minor snow events will impact the areas of Kentucky and Tennessee. It is very early to tell what will happen in this situation. We will keep you updated as a team here on FirstHandWeather. Sorry for such a short post. Take a look at the model run for the 0Z GFS at 6 PM on Monday the 17th. It says it all. Take care everyone.

    I was asked by one of your members to join this website and I replied telling him I’d take a look. I’ve yet to fully review the entire website. Now, let’s talk about this Snow event for the Deep South; thirteen days out on January 17; first, it’s 13 days and with each run 12 hours ticks away. As an analyst or forecaster one of my responsibilities is to determine what model best represents with run to run consistency of what the atmosphere is doing, what it’s likely to be doing and there is no way at 13 days that models can interpret with any degree of accuracy whether for example where the 540 decameter line is likely to be which it and the 546 decameter determine snow, ice and all rain. Yes, the models can determine what I call broad strokes or general trends. It’s not solely about the model run for the 17th; it’s each run and what is likely to occur on the 17th; a forecaster’s job is analyze whether there is continuity or run to run differences. It makes for a good story but today’s the 4th about to be 5th; there isn’t a good forecaster that looks at 288 hours from now or 312 hours, 24 hours ago and proclaims it’s going to snow in parts of the Deep South. The bottom line is it’s simply too far out to lock down a snow event that is almost two weeks away. Everybody is entitled to an opinion; however, I expect those opinions to equally bear out the facts.

    Hey Bill,

    I usually let my forecasters that work for me respond to the comments that are made on their particular post, but this comment particularly struck my attention. I think Josh did a great job on this post, but I do understand what you are saying. Long-tern events can be forecasted as I’m sure you know. Like you said, it is hard to determine the exact track and timing of a system, but a lot of times, you can get a good idea of what is going to happen down the road. Forecasting is not all about looking at forecast models all the time if you know what I mean. I put out a White Christmas forecast several weeks in advance indicating that that southern regions of the US would see a white Christmas, and that did happen. I think Josh did a really good job with this article, and he pretty well indicated what things were trending to at the moment. Anyways, I appreciate your corresponding with the forecasters on the site. I like your input, and I think it gives the Firsthand Weather forecasters accountability to what they say. Regarding a job position on the site, you will have to do like everyone else by sending in an application for review. Do so by going to the US jobs tab. Keep up the good work!

    Thank you for your kind words and the positive comments you extend to your forecasters. I’m at my desk and have looked at the 05/00Z package and now looking at the 05/12Z package. The Arctic Outbreak for the end of the week into early next week will impact the central US and will spread east and southeast; however, will moderate. The state of FL and its citrus crop will not be affected. The past couple of 1000-500mb thickness chart runs push the 540/546 decameter contour further north and cyclogenesis is likely to be closer to the Northern coast of the Gulf of Mexico than previous thought. There continues to be enough differences in the model consensus in the future track of the system up the east coast of the US. Aloft, there are two upper highs; an impressive 578 decameter center over Western Alaska and a 548 decameter center over extreme Northern Canada which 5 upper lows are pinwheeling around and as a result low heights from west to east over the US and a continuation of the cold weather pattern across much of the country east of the Rockies; however with the exception of the Northern and Central US; not as cold as previous outbreaks. “DONE” Sincerely, Bill Berry

    Today and tonight (January 6 & 7) there is a chance of snow as a shortwave moves rapidly over the area. The system expected to cross the area late this weekend into early next week continues to come in warmer across the south; however looking at temperature profiles and thickness I think a mixture of rain and snow is the wiser choice. I wouldn’t be surprised as the system moves east and away from the area that some colder air will be pulled south in its wake and some snow will fall. This system won’t be as deep as the previous nor likely will bomb out as it moves up the coast in the days ahead. It will be brutally cold over the central US; however this air will moderate as it settles more south and east. Low heights over the entire USA will keep things cool for sometime to come with upper highs and heights in Alaska where there is an impressive 578 to 580 decameter center forecast in 96 hours and what has become somewhat a semi-permanent feature on the charts; an upper high over extreme Northern Canada courtesy of the NAO.
