After yesterday’s cold front passed through much colder air is settling in behind the front. The strong north winds today will continue to bring the colder air into Central Alabama and the Southeast. The winds are expected to go calm this evening, and with no cloud cover, optimal radiational cooling will take affect. Temperature will drop like a rock as we head through the overnight hours and by tomorrow morning, many areas will have a hard freeze as the average low will be around 27. Some areas will be in the lower 20s. This is the coldest weather we have experienced this season. Freeze warnings extend all the way down to the Gulf Coast and into the Peninsula of Florida. The forecast map below shows many areas will be in upper 20s overnight.

High pressure is in control over much of the Eastern half of the United States. That is keeping beautiful and sunny conditions in place, but very cold conditions too. It is also responsible for our breezy north winds today. The cold front that brought in the colder weather has now pushed off the East Coast. The cold weather in place will be short-lived. As the high pressure pushes off to the east by late Sunday and will allow for warmer and more moist air to move back in.
In the Northeast today, the lake effect snow machine is piling up the snow on the south side of lakes Ontario and Erie. Conditions should begin to improve overnight and snow fall rates will begin to tamper off. Our next cold front and storm system is beginning to take shape in the Northern Plains. This front will continue to work south and east over the next few days and will likely cause some showers and thunderstorms across the Southeast Monday and into Tuesday. After that we can expect to return to cooler, drier conditions before our next storm system that could be in here for next weekend.
On this date in 2001, thirty six tornadoes touched down on a Saturday in Alabama, setting a record for the number of tornadoes in a single day for the state until that time. It surpassed the previous record for the state which was set during the April 3, 1974 outbreak, when 27 twisters hit the state.
Of course, the record would be shattered on April 27, 2011, when 61 tornadoes blitzed the state.
Interestingly, the November 24, 2001 tornadoes did not occur during the primary severe weather season, which occurs in the spring, but during the state’s secondary tornado season which occurs in the fall.
The first major tornado of the day cut a 39 mile path from near Kennedy in Lamar County to just south of Carbon Hill in Walker County. Two people died in a mobile home near Kennedy.
An F2 tornado cut a short path through the town of Haleyville in Winston County just before 11:30 a.m, injuring 13 people. Just northeast of Birmingham, an F2 tornado moved along I-59 near Argo as it cut a nearly 14 mile path into St. Clair County.
The strongest tornado of the day touched down about 1:19 p.m. CST southeast of Oneonta in Blount County. The tornado produced three distinct areas of F4 damage.
The other two fatalities of the day occurred near Sand Rock in Cherokee County just after 3 p.m. as an F2 tornado cut an 8 mile path. Again, the fatalities were in a mobile home.
Perhaps the luckiest break of the day came as aF2 formed on the western side of Pell City about 3:10 p.m. The tornado weakened as it moved across the downtown area, resulting in mainly light structural damage. Had the tornado been stronger, the damage and potential for injury or death would have been far greater.
The outbreak actually started the night before when tornadoes struck Arkansas and Mississippi, killing nine. The town of Madison, Mississippi was hard hit by an F4 tornado around 2 a.m.
Even though hurricane season officially ends at the end of November. No development is expected and we should end this very active hurricane season ending on the “T” storm, as Tropical Storm Tony was our last storm to be named.
However, with our season winding down, other parts of the world are beginning their tropical seasons. Case in point, the Southern Indian Ocean where Tropical Storm Boldwin has developed. Boldwin is not expected to impact any land masses, but there is some great satellite imagery of this system. Since Boldwin is in the Southern Hemisphere, you will notice that it has clockwise cyclonic flow, which is something that we are not use to seeing in the Northern Hemisphere. Boldwin is moving southwest at 8 knots and it will also continue to move off to the south and west towards the south pole. Maximum sustained winds are 45 knots (approx. 50 mph) and gusting to 55 knots (63 mph).
The current video lacks the audio I recorded. I’ve been working to figure out the problem without much luck so far. Sorry for the problem with the video!!!

Cold air advection is well underway after the cold front passed through the state yesterday. And an upper ridge will be positioned right over us tonight and early Sunday morning allowing temperatures to fall to the coldest values we’ve seen this Fall. Monday we’ll see temperatures recover somewhat as we get back to highs more typical of late November with a high around 65.
Monday a trough will dig into the Central US and bring us a shot at some rain late Monday night and into Tuesday. This system has some marginal potential for severe weather, however, SPC has not posted a slight risk area yet since the models have been fairly inconsistent with how they are handling it. Moisture should return into the ArkLaTex on Monday, and forecast soundings show some vertical shear that might be supportive of organized thunderstorms. The track of the surface low has also become more consistent as the GFS is bringing the low across northern Mississippi. So thunderstorms are a distinct possibility, and we’ll have to continue to monitor the development of conditions to see if there will be enough instability for severe storms. Be sure to check back with the Blog as we continue to keep a check on this system.
Rain should end from the west on Tuesday afternoon with another chilly day for us on Wednesday as the highs only reach the mid and upper 50s. Another short wave trough will move by on Friday, however, it doesn’t seem likely that this trough will have much moisture to work with, so other than a few clouds, we should stay dry into next weekend.
If you are headed out to the Iron Bowl, be sure to dress warmly. Today’s high may not get out of the 40s which is about 14 degrees below the average high for this date. A northwest wind at 10 to 15 mph will make those chilly highs feel even colder.
Looking out into voodoo country, there appears to be another shot at rain around the 5th of December, and with a mostly southwesterly flow aloft, we appear on track to be mild into the first week of December.
