Quite a Dichotomy

| 4:01 pm November 23, 2012

There is quite a dichotomy in the weather across Alabama this afternoon, thanks to a cold front that is cutting across the state.

The front is just south of the I-20 corridor at this hour. It was heralded by a about a 100 mile wide band of fairly thick clouds. It was associated with a line of showers and some isolated thunder through the overnight hours, but it weakened shortly after sunrise this morning. There probably have been a few sprinkles this afternoon across Central Alabama, but they haven’t amounted to much at all. The sprinkles were coming from some deeper moisture that accumulated just ahead of the front.

There is much drier air coming southeast behind the front. The dewpoint at Birmingham is 52F, while in Tupelo, it is 27F!

The late afternoon Skycam grabs superimposed on this picture show the dichotomy visually. Clear at Hamilton behind the front, and clear at Montgomery behind the front, while there were thick, wintry clouds at Birmingham.

Skies will clear quickly overnight in the I-20/59 corridors. Lows will drop into the lower 30s in the I-59 corridor, with some upper 20s in normally colder locations, and slightly milder readings to the southeast.

Tomorrow will be a chilly, brisk day, with temperatures struggling to get out of the 40s and an even cooler northerly breeze.

Expect a widespread freeze tomorrow night with the coldest air of the season so far.

Still expecting a round of rain and perhaps some thunderstorms late Monday night into Tuesday.

Cold Front Almost Here

| 8:30 am November 23, 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.

ON THE MAPS: The long awaited cold front is near Memphis this morning; ahead of the front a narrow band of showers is seen from near Greenwood, MS to the northwest corner of Alabama. These showers are slowly fading, and we don’t expect anything more than few sprinkles today over the northern quarter of Alabama. Measurable rain is very unlikely. We should reach the mid 60s today before the cold air floods in here tonight.

COLD SATURDAY: We begin the day tomorrow at or below freezing; the GFS is printing a low of 31 for Birmingham. Then, despite a sunny sky, there is a pretty good chance we won’t reach 50 degrees with a chilly north wind of 10-20 mph during the day. The GFS shows a high of 48 tomorrow, and that should be right on the money. Tuscaloosa could see 50 if they are lucky.

We drop well down into the 20s early Sunday, which will be our coldest morning so far this season; colder valleys will have a good chance of reaching the upper teens. Then, the day Sunday will be sunny and cool with a high in the upper 50s.

NEXT WEEK: The GFS continues to back off on the idea of severe weather here Tuesday, and the ECMWF is in pretty good agreement. So, we will mention a good chance of showers and storms late Monday night and Tuesday, but for now the severe weather risk is low. Rain amounts will be in the 1/2 inch range, and cooler and drier air will follow the rain on Wednesday. See the Weather Xtreme video for the details and graphics.

FOOTBALL WEATHER: For the high school playoff games tonight, temperatures will drop through the 40s with a chilly north breeze at 7 to 14 mph, but the sky will be generally clear.

Tomorrow’s Iron Bowl in Tuscaloosa will be dry and cold. The sky will be sunny with a kickoff temperature near 51 degrees. The mercury will drop into the mid 40s by halftime, and could very reach the upper 30s by the final whistle. A north breeze of 10-15 mph will make it feel colder.

UAB will travel to a warmer setting, where they play UCF in Orlando tomorrow (11:00 a.m. CST kickoff). The sky will be mostly sunny, with temperatures rising from near 66 at kickoff to around 70 degrees by the fourth quarter.

ELEVEN YEARS AGO TOMORROW: Three dozen tornadoes touched down in Alabama November 24, 2011, killing four people and injuring many more. Two deaths were at Sand Rock, in Cherokee County, and the other two were in West Alabama’s Lamar County at Kennedy. The National Weather Service in Birmingham issued 85 warnings including 58 tornado warnings for 33 counties and 27 severe thunderstorm warnings for 22 counties.

Coldest Air So Far Arrives Tonight

| 4:45 am November 23, 2012

**I will post a Weather Xtreme video later today when I arrive at ABC 33/40… we are on a holiday schedule through Sunday**

BIG WEATHER CHANGE COMING: Temperatures should rise into the mid to upper 60s across North-Central Alabama today with a mix of sun and clouds, but a cold blast rolls into the state late this afternoon and tonight. Ahead of the front, a few sprinkles are possible, mainly along and north of U.S. 278, but measurable rain is not expected since the air is so dry.

FRIGID SATURDAY: The good news is that the sun should out in full force tomorrow, but the day will be raw and cold. We start the day near the freezing mark, and much of North Alabama won’t make it out of the 40s despite the sunshine. Then, by daybreak Sunday with a clear sky and light wind, we project lows in the mid 20s for most communities around here. Some of the colder valleys might make a run at the upper teens for the first time this fall. Then, the day Sunday will be sunny and cool with a high in the upper 50s.

FOOTBALL WEATHER: For the high school playoff games tonight, temperatures will drop through the 40s with a chilly north breeze at 7 to 14 mph, but the sky will be generally clear.

Tomorrow’s Iron Bowl in Tuscaloosa will be dry and cold. The sky will be sunny with a kickoff temperature near 51 degrees. The mercury will drop into the mid 40s by halftime, and could very reach the upper 30s by the final whistle. A north breeze of 10-15 mph will make it feel colder.

UAB will travel to a warmer setting, where they play UCF in Orlando tomorrow (11:00 a.m. CST kickoff). The sky will be mostly sunny, with temperatures rising from near 66 at kickoff to around 70 degrees by the fourth quarter.

NEXT WEEK: A dynamic weather system will impact Alabama late Monday night and Tuesday. Run to run consistency has not been that great, and the last few models runs aren’t as bullish on severe weather. It hints at potential for strong storms, main in the window from midnight Monday night to 12:00 noon Tuesday. But, with limited instability, and a rather unfavorable surface pressure field, the severe weather threat looks somewhat marginal. But, this will probably change again as we get closer, so stay tuned. Looks like rain amounts of 1/2 to 1 inch are likely.

Colder and drier air returns Tuesday night.
