Interesting that the NAM has such a large gradient in its total predicted snowfall. If I’m reading it right, there will be almost no snow accumulation in Jasper, but 2.5″ in Hoover and 5″ in Jemison. OK…that may occur. But, … Continue reading →

Let’s dig into some dynamic meteorology here, before we get our last big set of models this evening before the event. The surface low is already developing off the Texas coast, with northerly winds blowing along the Texas Coast and … Continue reading →

The models, which had been out of agreement (with some predicting 5″ of snow), have come into agreement this afternoon (with the exception of the 18 UTC NAM, which is becoming more aggressive again with 5″ in BHM…maybe it sees … Continue reading →

The 00 UTC NAM, with new upper-air data, is in through 48 hrs (Saturday afternoon). It shows the system developing a little slower, with snow continuing for much of the day on Saturday. I’ll have a more complete post with … Continue reading →

First of all, the models are in fairly good agreement that a surface low will form along the stalled front in the Gulf of Mexico late Friday, bringing precipitation into parts of Alabama. With marginally cold air in place and … Continue reading →

Today turned out, for the most part (with the exception of some reported traffic accidents), a nice little winter weather event, with most spots over the northern half of the state at least seeing some sleet or snow, and areas … Continue reading →

As we’ve mentioned, even though the temp is just above freezing over most of Alabama except the higher elevations, be careful driving home this afternoon! It takes snow or sleet a minute or two to melt sometimes, and the roads … Continue reading →

The precip has moved into much of the Birmingham area over the past hour or so. Many reports on the blog coming in of snow and sleet. The sleet has been heavy at times here in Trussville. The sleet probably … Continue reading →
