Much Colder Air Arrives Tonight

| 3:22 pm January 31, 2013

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

CLIPPER ON THE WAY: Alabama is enjoying sunshine in full supply today, with temperatures hovering in the upper 40s and low 50s at mid-afternoon. To the north, a strong upper disturbance we call an “Alberta Clipper” is moving rapidly in our direction, and will pull down some very cold air late tonight and tomorrow.

SNOW SHOWERS? A very real possibility with the Clipper tonight, especially over Northeast Alabama. The latest RPM actually shows some potential for a snow shower all the way down to I-20 very early tomorrow, and that is not totally out of the question. The best chance of snow showers will come from about midnight to 6:00 a.m… and I could easily see a dusting on top of Lookout Mountain, and other higher terrain locations of Northeast Alabama. But, I doubt if it will be enough to create any travel issues.

COLD FRIDAY: The high for Birmingham will be about 40 degrees tomorrow… and locations north of Birmingham won’t get out of the 30s. Some of the traditionally colder pockets might even have a hard time getting above freezing. The first day of February will make us shiver, but at least the sun will be out. A very significant freeze is ahead for tomorrow night; we project lows in the 20-25 degree range early Saturday, with upper teens for the colder spots.

OUR WEEKEND: Clouds will increase Saturday ahead of a cold front, and we will mention the risk of a little light rain by mid to late afternoon, and into the evening hours. Moisture will be very limited, and rain amounts should be 1/4 inch or less for most places. We do note models have been hinting at some risk of snow flakes Saturday evening over far Northeast Alabama, but like tonight’s event we don’t expect any problems if that happens. Then, on Sunday, the sky becomes partly to mostly sunny with a high in the low to mid 50s.

NEXT WEEK: The week looks generally quiet with a slow warm-up; a good chance we reach the low 60s by Tuesday and Wednesday. The next decent chance of rain could very well come the following weekend (Feb 9-10)… see the Weather Xtreme video for more long range ideas and all of the maps and graphics.

I had a great time today visiting with the third graders at Alexandria Elementary School in Calhoun County… be looking for them on the Pepsi KIDCAM today at 5:00 on ABC 33/40 News! The next Weather Xtreme video will be posted by 7:00 a.m. tomorrow…

A Brighter Day; Cold Shot Tonight

| 5:59 am January 31, 2013

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

COLDER, DRIER: Temperatures early this morning are near the freezing mark at most communities, and the sky has cleared. Expect sunshine in full supply today with a high in the low 50s in most spots.

SNOW SHOWERS TONIGHT? An “Alberta clipper” type system will roll through the state tonight. These rarely have much moisture, but they do feature some decent lift, and we will mention a few snow showers tonight over the northeast corner of Alabama. Places like Scottsboro, Fort Payne, and maybe even Gadsden could see a few snow flakes from about midnight until 3:00 a.m., but no accumulation is expected and most people will sleep through it.

ONE DAY COLD SHOT: Following the clipper tomorrow will be much colder. Communities north of Birmingham won’t make it out of the 30s; we might see low 40s along I-20 (Tuscaloosa, Birmingham, Anniston). The sky will be sunny thankfully. Then, tomorrow night, a very significant freeze is likely with a low in the mid 20s likely by daybreak Saturday.

WEEKEND FORECAST: Clouds will increase Saturday ahead of a cold front, and that front will have the potential to bring a little light rain Saturday afternoon into Saturday night. Model trends show the best chance of light rain from about 3:00 p.m. Saturday until 10:00 p.m. Amounts should be under a quarter of an inch with very limited moisture. And, a snow flake or two is possible Saturday night with this feature over far Northeast Alabama, but nothing significant is expected.

Sunday will be a dry day with ample sunshine statewide. The high both days will be in the 50s.

NEXT WEEK: The first half of the week looks rain-free with a slow warming trend; a chance we visit the 60s by mid-week. See the Weather Xtreme video for more long range ideas and all the graphics that go along with this discussion.

I will be doing a weather program this morning at Alexandria Elementary School in Calhoun County…. look for the next Weather Xtreme video here by 4:00 this afternoon. Enjoy the day!

Interesting Temperature Trend

| 5:54 am January 31, 2013

It was another challenging and interesting weather day across the Southeastern US yesterday. The hardest hit places seem to have been in Tennessee and in North Georgia. Preliminary storm report maps from SPC show that the overall two-day event was significant.

SPC Reports 20130120

SPC reports 20130130

Temperatures

While the severe weather is always interesting and attracts a great deal of attention, I find that looking at other weather elements can also be interesting. Yesterday was one of those days where the typical trend in temperature was completely out of whack. A typical day usually shows a nice sinusoidal pattern with the lowest temperature coming around daybreak and the highest temperature coming around mid-afternoon.

Yesterday was NOT typical!! Take a look at the temperature trace below for my weather station in Helena. The temperature actually held steady nearly all night from midnight until just after 8 am when a significant round of rain occurred with the line of storms that moved through Central Alabama. This dropped the temperature a bit more than 10 degrees.

The temperature held fairly steady throughout the day with slow downward trend where you would expect an upward trend as the rain continued. Drier air arrived around 6 pm along with colder air that began a steady downward trend until this morning – a drop of nearly 40 degrees from the temperature just 24 hours ago.

OutsideTempHistory-2

We should see the more typical sine wave pattern in the temperature trace today, but the change will be substantially less than yesterday with a high only in the lower 50s expected. The downward trending of temperature will continue Friday with highs another 10 degrees colder than today.

Rainfall Records

By the way, two new records were set in Central Alabama yesterday. At the Birmingham International Airport, 1.82 inches of rain fell breaking the old record of 1.45 inches set in 1999. And at the weather observing site for Anniston, a record 2.65 inches of rain fell shattering the old record of 1.35 inches set in 1991. Both of those were a tad higher than the 1.75 inches that was recorded by my rain gauge.

A Brighter Day Tomorrow

| 3:23 pm January 30, 2013

**No Weather Xtreme video today due to the severe weather situation… we will get back to the regular schedule tomorrow**

RAIN ENDING: The rain will continue to taper off from west to east this evening across Alabama…

Screen Shot 2013-01-30 at 3.11.00 PM

Temperatures have dropped in the 50s, and we will be very close to freezing early tomorrow. The clouds move out late tonight, and tomorrow should be a day with maximum sunshine and a high in the low 50s.

COLD SHOT ON FRIDAY: Noticeably colder air blows in here tomorrow night; we will be in the 20s early Friday, and it looks like we will need to drop the afternoon forecast high on Friday to the low 40s with a chilly north breeze. Communities north of Birmingham, most likely, won’t make it out of the 30s Friday afternoon as frigid air returns to Alabama. The sky will remain sunny Friday.

OUR WEEKEND: The daytime hours Saturday should be dry, with a partly sunny sky and a high in the 50s. The next issues comes Saturday night with a cold front swinging through. The 12Z GFS shows some potential for either light rain, or light snow Saturday night and early Sunday…

gfs_precip_thick_east_16

The GFS keeps accumulating snow to the north of Alabama with this feature…

gfs_snow_depth_east_33

So, for now, we will just mention mainly some light rain Saturday night, with the risk of a few snow flakes as the precipitation ends early Sunday. We will fine tune this as we get a little sleep and get closer to the event.

The sky will clear by midday Sunday, and the high should be around 50 degrees Sunday afternoon.

Dry weather is likely early next week with a warming trend; low 60s are possible by Tuesday and Wednesday.

ADAIRSVILLE, GA TORNADO: The tornado that struck this North Georgia community this morning, killing one person, originated from a storm that went right over Anniston; a tornado warning was in effect for Calhoun and northern Cleburne Counties, but to my knowledge there was no damage from the storm in Alabama.
