A strong storm system will continue to impact the region on Tuesday with lingering showers likely and winds will remain an important factor as well. Also, there is enough instability around that the chance of a strong thunderstorm is on the table; especially, north of the I-20 corridor later today. The threat of rain will diminish tonight and Wednesday and the Thursday holiday is shaping up pretty nicely weather wise.

After back-to-back-to-back La Nina (colder-than-normal water) winters, El Nino (warmer-than-normal water) has formed in the tropical Pacific Ocean and it will play an important role in the upcoming winter season across the nation as discussed in the Arcfield Weather 2023-2024 “Winter Outlook”. Two aspects of El Nino are important when it comes to its potential impact on winter weather patterns in the US and they include both its magnitude and location. Evidence continues to mount suggesting this El Nino event will not rival some of the strongest episodes in recent history such as in 2015-2016, 1997-1998 or 1982-1983. Instead, and as outlined in the “Winter Outlook”, it appears this El Nino will be one of moderate strength and will tend to weaken as we progress through the winter season. In terms of the location with respect to the greatest sea surface temperature anomalies in the equatorial Pacific, the thought was that an “eastern-based” focus would shift to more of a “central-based” and recent developments suggest this transition may already be getting underway.

Strong upper-level low pressure will push towards the Tennessee Valley today and increase the chance of showers and thunderstorms by tonight and the threat of rain will continue on Tuesday. Some of the rain tonight can be heavy at times; especially, during possible strong thunderstorm activity. Winds will also become an important factor during this event with gusts to 50 mph on the table for tonight. Dry weather should return later tomorrow into Thursday with the holiday looking dry and cool with highs well up in the 50’s.

It stays unsettled in the region today with the chance of afternoon showers as moist air pushes in on low-level southeasterly winds. A cold front moves through the area on Friday night and its passage will pave the way for a cool, but dry weekend in the northern part of Alabama. Widespread frost is possible late Saturday night/early Sunday morning as temperatures should drop to near the freezing mark.

A widespread and impressively cold air mass will cross the nation next week and reach the eastern seaboard in time for Thanksgiving Day (Thursday). A strong storm system will develop out ahead of the incoming cold air mass and it will impact a large part of the nation with rain, snow and wind on the busy travel days of Tuesday and Wednesday.

It stays unsettled in the region for the next couple of days with the chance of showers as moist air pushes in on low-level southeasterly winds. A cold front will then move through the area on Friday night and its passage will pave the way for a cool, but dry weekend in the northern part of Alabama.

The overall weather pattern across the nation is becoming more and more active compared to recent days and it is likely to result in a strong storm system by the middle of next week that impacts a wide area from the Great Lakes and Midwest to the Mid-Atlantic and Northeast US. In terms of temperatures, the overall pattern will flip across the nation from today’s widespread warmer-than-normal conditions to below-normal for the last ten days or so of the month of November. In fact, a widespread cold air mass with its origins in northern Canada will sweep across the nation next week from northwest-to-southeast…just in time for the Thanksgiving Day holiday. This is very likely not going to be the last cold blast for the eastern half of the nation as the colder pattern that sets up next week will likely take us to the beginning of December.

It turns cooler today across the northern part of Alabama and increasing moist with the chance of showers.

Drier and cooler air pushes into the Tennessee Valley this weekend.

It stays mild today across the northern part of Alabama and increasing moist. As a result, the chance of showers will increase here by tonight and remain high on Wednesday and Wednesday night. Low pressure over the Gulf will keep us moist later in the week so that the chance of showers is likely to remain on Thursday and Friday before drier air pushes in for the weekend.
