A Freeze Likely Early Tomorrow

| 3:02 pm November 12, 2012

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.

THIS AFTERNOON: Our cold front is well to the south and east of Birmingham at mid-afternoon, and as expected, temperatures have been steadily falling across our state today. Haleyville, in Winston County, is down to 46 degrees at 2:00, while south of the front Eufaula is at 78. The rain is now mostly south of a line from Heflin to Montgomery to Greenville, and the sky has cleared over the northwest corner of the state. The ABC 33/40 SKYCAM network is showing blue sky at places like Hamilton, Russellville, and Muscle Shoals.

FREEZING TEMPS AHEAD TONIGHT: The clearing line will move steadily south and east tonight, and everybody should be clear after midnight. This, along with a cold, continental airmass and diminishing wind, should mean the coldest night so far this season for much of Alabama, with morning lows generally in the 26 to 33 degree range early tomorrow. For those communities that have not experienced a freeze, tonight will wrap up the 2012 growing season.

REST OF THE WEEK: Our weather will be dry tomorrow through Friday with a slow day to day warming trend. The high will be in the mid 50s tomorrow, upper 50s Wednesday, and then into the low to mid 60s Thursday and Friday. We should note Wednesday morning will be cold again with lows well down in the 30s, with a freeze for the colder spots.

OUR WEEKEND: Looks like Alabama will stay dry, but to the east another nor’easter will form just off the U.S. Atlantic coast that could bring more wind and rain for our friends impacted by Sandy not long ago. Expect a good supply of sunshine around here Saturday and Sunday, with highs in the low 60s, and lows in the 40s early Saturday, and 30s early Sunday morning.

THANKSGIVING WEEK: Remember, there isn’t much skill in a specific forecast beyond seven days… so all of this could, and probably will change. But, for now, the GFS is pretty persistent with the outlook for next week. Wednesday 11/21 here in Alabama looks dry and pleasant with a high in the 60s. Then, clouds increase Thanksgiving Day with some risk of showers by afternoon, followed by a better chance of showers on “Black Friday”.

We note the 12 GFS hints at a good rain/storm event as the holiday weekend ends (Sunday 11/25), followed by the coldest air so far this season by Monday 11/26, with highs only in the 30s. But this is all voodoo, and again expect some changes.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tonight at 8:30 CST… you can watch live here, or on our digital Weather Channel, James Spann 24/7.

Front Knocking on Our Door!

| 9:48 am November 12, 2012

The cold front we’ve been talking about for days is knocking on our door just before 10 am. Checkout the graphic below and it is pretty easy to see the wind shift line which is poised just west of Birmingham. The wind shift line runs from just east of Huntsville to a point between Birmingham and Tuscaloosa and then southward to just east of Mobile. Temperatures ahead of the wind shift were in the 60s, but once the wind shift occurs at your location, the temperature will drop quickly into the mid 50s.

Most of the rain was just ahead of the front, but some patchy light rain and spotty showers were occurring about 50 miles or so behind the front. Back in West Tennessee, temperatures were in the 40s.

As James noted, today is one of those days when the temperature goes the wrong way from a typical day.

A quarter of an inch of rain at my house with this system, a little below what I expected to see.

Soaking Rains This Morning

| 9:00 am November 12, 2012

Widespread showers this morning across much of north-central Alabama, with even a few rumbles of thunder being reported. A nice, much needed soaking rain this morning should continue to push east through out the morning and into the afternoon. The cold front has made it into Alabama and is moving down I-22/Corridor X between Tupelo and Birmingham. Once the front passes by your location, you will notice a temperature difference and a wind shift out of the North/Northwest. The high for today has already occurred and temperatures will be falling all day along. We should be in the 50s most of the day, later this evening into the 40s and overnight  down into the low-to-mid 30s. Many areas will be flirting with that freezing mark by tomorrow morning.

A quick look at the radar shows the heaviest rain moving through the Birmingham metro right now, but is beginning to taper off back toward the Mississippi state line. Expect a few light, lingering showers this afternoon, and we don’t expect to see sunshine today as the clearing line is still west of the Mississippi River.

Storm Alert Xtreme 2012!

| 8:16 am November 12, 2012

Another packed house for our annual storm spotter training at the BJCC… a special thanks to everyone who attended Saturday.

Each session video is below. There is a tad of audio noise due to some interference from our wireless mic, but it isn’t too bothersome hopefully. A special thanks to ABC 33/40 Skywatcher John Brown for bringing in his equipment so the event could be streamed live and recorded. These recordings are from the uStream channel we used to live stream the event. The camera is focused on the big screen so you can see the graphics easily.

INTRO SESSION

I shared an update on the ABC 33/40 Skywatcher program, and some information about the April 27, 2011 generational tornado outbreak, and social media.

Wet With Falling Temperatures

| 6:21 am November 12, 2012

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.

TEMPS GO THE WRONG WAY: We begin this Monday with rain over much of Alabama ahead of a strong cold front that is near the northwest corner of the state at daybreak. There won’t be any severe weather, just rain and some thunder, and the bulk of the rain should be over by midday or early afternoon as the wet weather ends from west to east. Rain amounts of about 1/2 inch are likely; some spots might see up to 3/4″.

The high for today will come early this morning, as temperatures are in the 60s over North-Central Alabama to start the day. Plan appropriately as you dress; we will fall through the 50s today, reaching the 40s by mid to late afternoon. Northwest Alabama could even reach the 40s by the lunch hour. Bottom line is that it will be a wet, cold, and rather miserable day.

FREEZE EARLY TOMORROW: The GFS is printing a low of 30 degrees for Birmingham early tomorrow, and that sounds right. A deep, cold airmass is over the Central U.S. this morning, with sub-zero cold over parts of Montana and North Dakota with a big snow pack. With a clearing sky and diminishing wind, freezing temperatures are indeed likely over much of North and Central Alabama early tomorrow, with most places seeing a low in the 26 to 33 degree range.

REST OF THE WEEK: We will be dry tomorrow through Friday with a slow, day to day warming trend. We reach the mid 50s tomorrow, followed by a high near 60 Wednesday. Then, low 60s are a good bet Thursday, followed by mid 60s Friday. Days will be mostly sunny, and nights fair and cold. We should note another freeze is possible early Wednesday morning, but lows won’t be as cold early Thursday and Friday.

WEEKEND PEEK: For now our weekend looks dry, with highs in the 60s and lows in the 40s early Saturday, and 30s at daybreak Sunday. Another nor’easter type storm will develop just off the U.S. Atlantic coast over the weekend, but there will be no direct impact on Alabama, other than pulling down slightly cooler air Sunday.

THANKSGIVING FORECAST: Long time readers know there is little skill in a specific forecast beyond seven days, but we can peek at next week and give you some ideas. Better yet, watch the Weather Xtreme video for the graphics.

The latest GFS run in hand suggests showers will be possible over about the northern half of Alabama on Thanksgiving Day and “Black Friday”, but nothing too heavy, and no severe weather. But again, this is just an idea, we won’t be able to give a specific forecast until later in the week.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will record this week’s show at 8:30 tonight… you can watch live here, or on our digital weather channel, James Spann 24/7 on cable systems around the state.

Winter Weather Awareness Week

| 6:20 am November 12, 2012

In order to draw attention to upcoming weather threats, the National Weather Service (NWS) offices around the country conduct awareness week campaigns aimed at educating people on how to be prepared for those threats. This week is Winter Weather Awareness Week in Alabama, and the NWS in Birmingham will be issuing special releases each day intended to help you be better prepared should we have an episode of winter weather. Here is the release for today.

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BIRMINGHAM AL
501 AM CST MON NOV 12 2012

...WINTER WEATHER AWARENESS WEEK STARTS TODAY IN ALABAMA...

THE NATIONAL WEATHER SERVICE, AND THE ALABAMA STATE EMERGENCY
MANAGEMENT AGENCY HAVE PROCLAIMED THE WEEK OF NOVEMBER 12TH
THROUGH NOVEMBER 16TH, 2012 AS WINTER WEATHER AWARENESS WEEK IN
ALABAMA. WINTER WEATHER AWARENESS WEEK HIGHLIGHTS THE NEED FOR
BEING PREPARED FOR THE POTENTIAL DANGERS OF A SEVERE WINTER
WEATHER EPISODE.

...WINTER WEATHER ACROSS CENTRAL ALABAMA...

ALABAMA IS NO STRANGER TO WINTERS DEADLY GRIP. HISTORICALLY, SOME
OF THE MOST SEVERE WEATHER CONDITIONS WHICH CAN AFFECT SOME OR
ALL OF THE STATE HAVE COME IN THE WINTER. EACH YEAR WEATHER
PATTERNS BRING SEVERAL WINTER WEATHER THREATS TO THE STATE
INCLUDING EXTREME COLD, SNOW, SLEET AND FREEZING RAIN.

...WINTER WEATHER HISTORY IN CENTRAL ALABAMA...

ON FEBRUARY 9TH, 2011, SNOWFALL TOTALS FROM A LOW PRESSURE SYSTEM
FROM THE GULF OF MEXICO RANGED FROM 4 INCHES IN LAMAR COUNTY TO
TRACE AMOUNTS ALONG THE INTERSTATE 85 CORRIDOR.

BY DAYBREAK ON MONDAY, JANUARY 10TH, 2011, AREAS NORTH OF
INTERSTATE 20 REPORTED ANYWHERE FROM 1 TO 14 INCHES OF SNOW WITH
THE HEAVIEST TOTALS NEAR THE ALABAMA-TENNESSEE STATE LINE. ICE
REPORTS WERE AS HIGH AS 0.50 INCHES IN MULTIPLE COUNTIES SOUTH OF
INTERSTATE 20.

SNOWFALL BLANKETED MUCH OF THE NORTHERN AND CENTRAL ALABAMA ON
DECEMBER 25TH, 2010. SOME LOCATIONS SAW THE FIRST WHITE CHRISTMAS
ON RECORD, WHILE OTHERS JUST MISSED OUT.

ON MARCH 1, 2009, SNOW BLANKETED CENTRAL ALABAMA. CITIZENS AS FAR
SOUTH AS MONTGOMERY SAW AT LEAST A DUSTING, BUT MOST EVERYONE SAW
SNOWFALL TOTALS BETWEEN 1 AND 5 INCHES, WITH THE HEAVIEST TOTALS
AROUND AUBURN, WHERE LEE COUNTY SAW OVER 5 INCHES OF SNOW.

ALMOST THREE YEARS AGO ON JANUARY 19, 2008, SNOW FELL ACROSS
CENTRAL ALABAMA. AREAS FROM DEMOPOLIS TO SELMA TO CLANTON RECEIVED
2 TO 5 INCHES OF SNOW. AREAS AS FAR NORTH AS BIRMINGHAM AND
SOUTH TO MONTGOMERY RECEIVED UP TO ONE INCH.

BACK ON JANUARY 28-29, 2005, AN ICE STORM OCCURRED ACROSS EASTERN
ALABAMA. ICE ACCUMULATIONS OF ONE QUARTER TO ONE INCH CAUSED
SIGNIFICANT ICING AND WIDESPREAD POWER OUTAGES ACROSS RANDOLPH AND
CHAMBERS COUNTIES. MUCH OF THE REMAINDER OF EAST ALABAMA RECEIVED
LIGHTER ICE AMOUNTS WHERE POWER OUTAGES WERE LESS WIDESPREAD AND
DAMAGE TO TREES WAS RELATIVELY MINOR. LIGHT ICING WAS REPORTED AS
FAR WEST AS BIRMINGHAM AND MONTGOMERY.

IN MARCH 1993, THE STORM OF THE CENTURY OCCURRED. THE STATE WAS
HELD IN THE GRIP OF RECORD SNOWFALL WITH MORE THAN A FOOT OF SNOW
ACROSS A WIDE PORTION OF CENTRAL ALABAMA. THE SNOW COMPLETELY
PARALYZED A LARGE SECTION OF THE STATE. STRONG WINDS ACCOMPANIED
THE HEAVY WET SNOW AND THIS COMBINATION DOWNED NUMEROUS TREES AND
POWER LINES. MANY PEOPLE WERE LEFT WITHOUT ELECTRICAL SERVICE FOR
SEVERAL DAYS. HEAVY SNOWFALL ON MARCH 12 AND 13 WAS FOLLOWED BY A
RECORD BREAKING COLD SNAP. NEARLY ALL ACTIVITY CAME TO A COMPLETE
HALT IN AND AROUND BIRMINGHAM, ANNISTON, AND TUSCALOOSA FOR TWO
FULL DAYS UNTIL THE SNOW BEGAN TO MELT AND EMERGENCY EQUIPMENT
COULD BEGIN TO CLEAR ROADWAYS. WHEN THE WINTRY PRECIPITATION AND
COLD CONDITIONS SUBSIDED, 14 PEOPLE HAD DIED AND MANY MORE WERE
INJURED. PROPERTY DAMAGE EXCEEDED 50 MILLION DOLLARS AND EVERY
SQUARE INCH OF ALABAMA HAD EXPERIENCED MEASURABLE SNOW. DURING THE
WINTER STORM, THE AMERICAN RED CROSS IN ALABAMA SHELTERED OVER
12000 PEOPLE IN 108 FACILITIES AND SERVED OVER 36000 MEALS.

AN OUTBREAK OF SEVERE COLD WEATHER OCCURRED DECEMBER 22 THROUGH
25, 1989, KILLING FIVE PEOPLE IN ALABAMA. LOW TEMPERATURES FOR TWO
CONSECUTIVE NIGHTS DROPPED INTO THE 0 TO MINUS 5 DEGREE RANGE OVER
THE NORTHERN THIRD OF ALABAMA AND INTO THE SINGLE DIGITS ALL THE
WAY TO THE GULF COAST. DAYTIME HIGH TEMPERATURES REACHED ONLY INTO
THE TEENS. BRISK NORTHERLY WINDS CREATED WIND CHILLS AS LOW AS
MINUS 15 TO MINUS 35 DEGREES BELOW ZERO OVER NORTH ALABAMA AND
ZERO TO MINUS 15 IN SOUTH ALABAMA.

AT LEAST 5 PEOPLE PERISHED IN THE EXTREME COLD OF JANUARY 19
THROUGH 22, 1985. THIS EVENT RE-ESTABLISHED LOW TEMPERATURE
RECORDS OVER MUCH OF ALABAMA. THIS STORM BROUGHT ICE ACCUMULATIONS
OF UP TO ONE FOOT AS REPORTED IN LAUDERDALE COUNTY. BRIDGES WERE
COATED WITH ICE WELL INTO CENTRAL ALABAMA AND FOUR PEOPLE WERE
KILLED IN TRAFFIC ACCIDENTS ON ICY ROADS.

ONE OF THE MOST TRAGIC OUTBREAKS OF COLD WEATHER IN ALABAMA
HISTORY OCCURRED JANUARY 10 THROUGH 18, 1982. TWENTY PEOPLE DIED
AND 300 WERE INJURED DURING THIS EXTREMELY COLD WEATHER. SIXTEEN
THOUSAND PEOPLE WERE FORCED INTO EMERGENCY SHELTERS AND STORM
DAMAGE TOTALED SOME 78 MILLION DOLLARS.

THE ARCTIC OUTBREAK OF DECEMBER 19 THROUGH 21, 1981, TOOK THE
LIVES OF AT LEAST TWO PEOPLE IN UNHEATED HOMES AND AT LEAST 17
PEOPLE WERE INJURED BY SLIPPING AND FALLING ON ICE.

TUESDAY'S WINTER WEATHER TOPIC WILL BE WINTER WEATHER TERMINOLOGY.
