The onslaught of Pacific Ocean storms into California will continue for at least the next 7-to-10 days with “off-the-chart” rainfall and snowfall amounts. After slamming into California, these storms have traveled across the country making for an overall active weather pattern across much of the US. In some cases, the impact has been large such as with the severe weather outbreak earlier this week in the Lower Mississippi and Tennessee Valleys and in other cases, systems have weakened considerably by the time they have reached the eastern states. We’ll examine upcoming threats in the Mid-Atlantic/Northeast US with small snow accumulations possible as early as Sunday night and perhaps the greatest chance for a strong storm system coming in the period of January 13-15th.

Our warming trend will intensify over the next few days as high pressure builds over the western Atlantic Ocean. As a result, temperatures around here will climb to near 60 degrees for highs both this afternoon and on Friday afternoon and then likely well into the 60’s this weekend. This increasingly mild pattern will become increasingly moist as well with a shower and thunderstorm threat from Friday into the middle part of next week. In fact, a severe weather outbreak is on the table for the Tennessee Valley during the early-to-middle part of next week as an overall very active weather pattern continues across the nation.

The strong Arctic frontal system that represents the leading edge of an intensely cold air mass will reach the Huntsville region later tonight. It’ll stay mild through the day with rain showers possible and then the bottom will fall out with temperatures post frontal passage plunging all the way to single digits by Friday morning. Snow showers are possible late tonight and winds will be very strong adding to potential difficult travel conditions. A frigid weekend will follow with Christmas Eve (Saturday) and Christmas Day (Sunday) the coldest in many years in much of the eastern half of the nation.

The core of an intensely cold Arctic air mass is now getting ready to plunge southward to Texas by later tomorrow and then it’ll shift to the eastern states on Friday. Numerous low temperature records are likely to be set over the next couple of days as this air mass makes its way across the nation. Blizzard conditions will accompany this advancing Arctic air outbreak over much of the eastern half of the country with the Great Lakes region likely to experience some of the worst weather with an extended period of extreme conditions from Friday into late weekend.
The powerful Arctic frontal system that represents the leading edge of this intensely cold air mass will reach the DC-to-Philly-to-NYC corridor during the late morning/mid-day on Friday. Temperatures will drop dramatically in the wake of the frontal passage some 30+ degrees in a short period of time. Any wet spots on roadways from prior rainfall could freeze-up in a hurry. There will be very strong wind gusts on Friday and a burst of snow is likely immediately behind the frontal passage that can produce a quick coating to an inch or two. A frigid weekend will follow with Christmas Eve (Saturday) and Christmas Day (Sunday) the coldest in many years across much of the eastern half of the nation. Single digits are likely in many spots along the I-95 corridor both on Saturday and Sunday mornings.
