After one of the warmest February’s on record for a large portion of the eastern-third of the nation, a rather un-welcomed change is on the way as we head into March. Temperatures soared past the 60’s all the way up into parts of New England today, but a storm gathering in the center of the country is about to make that a distant memory as just 48 hours from now many of these same areas will be blanketed in inches of snow. Overnight and into tomorrow morning rain showers will continue to increase across the central and midwestern part of the country, as an area of low pressure begins to deepen just a few hundred miles to the south and east of Chicago. As this storm strengthens, it will pull cold air from the north and begin changing rain over to snow on the extreme northern fringe of the system,…

As a cold front moves through, this will set the stage for a fresh batch of cold air to sit over the Northeast region on Saturday as showers and thunderstorm begin organizing across the southern United States. By Saturday night our fast moving storm system will spread rain across much of the southeast and Mid-Atlantic as snow begins to breakout from Ohio to southern PA. As this happens late Saturday and Saturday night, our storm system will begin to rapidly strengthen as it exits the coast, producing a swath of moderate to heavy snow either just along I-95 or just to the northwest. This is where the forecast becomes unclear. Above we have two different models – The top model is the GFS (Global American Model) and the bottom is the NAM (Mesoscale American Model). There’s a solid 50-100 mile difference in the placement of the low pressure, with the…

The new pattern we discussed last week seems to be holding itself nicely as we watch yet another storm system move into the region with heavy snow for the interior and a mixture of snow and ice for the coastline. Forming out west and moving eastbound, this winter storm will likely cause headaches for millions by the middle of this week. The major difference with this system compared to the last, seems to be the possibility of colder air holding on a bit longer, potentially expanding the region of snow and ice further towards the coastline on Wednesday morning. Our winter storm will begin moving out of the western states later tomorrow, producing snow to the north across parts of the Plains and spotty shower and thunderstorm activity to the south across nearly all the southern states. As the two separate areas of convection begin merging together overnight on Tuesday…
