Yes, temperatures will be well into the 60’s this afternoon and ground temperatures in the 40’s to near 50 degrees — but Mother Nature could throw us a surprise snow. It’s a very interesting setup. Cold air timing with heavier precipitation have to meet in order for this to work out.
Over the past few days, models were slowly introducing a coating of snow accumulation, however, it appears that there WILL be a wave of moisture that develops along the arctic, meeting the colder air behind it. There were hints about this last week, but temperatures trended warmer. We cautioned everyone that if models “suddenly” take everything away completely, it may not be totally correct. That’s why we stick to ensembles, which continued to show a minor accumulation — especially the European ensemble and has kept a small hint of accumulation every ensemble model run since last week!
7 AM TUESDAY – RADAR AND TEMPERATURES
Tuesday morning, the arctic front is crossing the mountains. Snow will develop across Southwestern Virginia. Even at lower elevations in Northeast Tennessee and Far Southwest Virginia (Bristol area,) snow will likely accumulate around an inch. Higher amounts will be confined to above 2,000 feet, up to 3 inches.
