A rather quiet start to the new week will evolve into a busy one by the latter half — similar to last week — as several, large storm systems dominate the eastern US’ pattern.
This is your 5 things to watch this week.
Fall Arrives to Lower 48:
The entire contiguous US has finally experienced fall-like conditions, even in Florida where it took up until this past Sunday (October 28) for cooler and even below average temperatures to invade and significantly lower dew points, or drier air. This morning, parts of the interior of South Florida got down to the upper 40s for a low temperature while the coast was cool into the mid 60s, which is a few degrees cooler than normal. Humidity levels will gradually increase this week while high temperatures return to slightly above average at around the mid 80s paired with mainly dry weather.
Spooky Halloween Storms:
Scattered severe thunderstorms are becoming increasingly likely on the afternoon and evening on Halloween across parts of the southern Plains. Damaging winds, small hail, and isolated tornadoes will be the main threats. Trick or treating may need postponed, especially in southeastern Texas, due to the risk for widespread convection and potential, localized flash flooding. This will be associated with a strengthening low pressure over the region, which will bring showers and thunderstorms to most of the eastern US mid- to late- week.
Yet another named storm has formed this past weekend in the Atlantic basin. Originally an invest a few days ago, once the National Hurricane Center designated this area of disturbed weather as Tropical Storm Oscar, it quickly intensified into a hurricane, making it the 8th hurricane of the 2018 Atlantic hurricane season. A typical season features 6 hurricanes. Thankfully, Oscar is located over the central Atlantic Ocean and will be taken to the north and east thanks to a cold front, affecting only the fish,
As the seasons change, the storm pattern continues to become more active across the northwestern US, a usual situation for this time of the year. Rounds of storms — likely 4 to 5 — are forecast to affect the region this week, bringing showers, some of which may be heavy, to the lower elevations while snow comes down in the higher elevations, like the Cascade Mountains. By the end of this week, some of the peaks may record over a foot of snowfall.
Wet Midwest and Northeast:
Similar to the Northwest, the Midwest and Northeast will be in for an active weather, especially beginning late-week. The first storm will be the one that brings severe storms to the southern Plains on Wednesday before it moves to the north and east, ushering in ugly, wet weather to much of the Midwest and Northeast between Wednesday and Saturday. On the heels of that storm will be a second, which will form over the central Plains. This next storm will head east, making its way to the East Coast by early-next week. a third, potentially robust storm may then follow for the middle to late part of next week. As a result, the model guidance continues to suggest a widespread 1 to 4 inches of rain falls across much of this part of the country, indicating wet times ahead.
