Multiple nor’easters are set to form this week while cooler than average temperatures impact much of the Lower 48. We’re monitoring that as well as the deadly California wildfires in this week’s 5 Things to Watch.
Several large wildfires have broken out across California within the past week, and they remain uncontrollable as above average temperatures, low humidity, and dry air continue to make for favorable conditions for these fires to grow even further. As of Monday morning, 31 people have died but over 200 people are reported missing as a result of these blazes. The forecast this Monday and Tuesday will continue to feature the extreme fire conditions, but the forecast does hint at better weather as the week progresses for the firefighters to battle these massive wildfires.
A developing nor’easter, which will hug the Northeast coast, early-week is set to bring heavy rain to the coast, including the entire I-95 corridor while heavy snow impacts the higher elevations of the interior Northeast. Because the center of this low pressure will track right along the coast, the warm air intrusion will extend further inland than these typical coastal storms, minimizing the extent of the snow. Nonetheless, several inches of snow are expected in these higher elevations while a general 1 to 2 inches of rain falls closer to the coast.

Chill Dominates Eastern US:
A relentless troughing weather pattern will keep below average temperatures across most of the eastern two-thirds of the US for yet another week. The most significant of this cold will take place early-week as temperatures drop to as much as 45 degrees below average in the Southwest and southern Plains. Elsewhere, it will be more like 10 to 30 degrees below average east of the Rocky Mountains. There will be a brief round of warmth that invades parts of the Plains and Midwest midweek before the cold air takes control once again by the end of the week. Even Florida will lose luck on Friday as a cold front sweeps trough, ushering in temperatures of up to 10 degrees below average.
Southern Severe Weather:
A Tornado Watch was issued this morning for parts of the central Gulf Coast as the development of supercell thunderstorms possibly lead to tornadoes both this morning and this afternoon. According to the Storm Prediction Center, the greatest chance for severe storms and tornadoes will be from southeastern Louisiana through the western Florida Panhandle. There will also be a separate threat beginning tonight to the east of there along the Carolina coast. The storms that develop there will threaten the region with damaging winds and an isolated tornado.
A second nor’easter will develop late-week and will impact the Mid-Atlantic and Northeast. Since this system will track a bit farther offshore while colder air is in place, that will mean more people will deal with the snow — at least for a brief time. Even parts of the I-95 corridor, like New York City and Boston, may see a few, non-accumulating snow flakes. Where the accumulations will take place is across the interior Northeast, possibly as close to the coast as northwestern Connecticut and Maine. Elsewhere, rain and gusty winds will be the story for the I-95 corridor.
Stay tuned for additional details on this storm later this week.
