Cold Air Blast Sunday

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

BIG CHANGE COMING: While Alabama has been an oasis of warmth in recent days, while most of the nation has been buried in cold air, snow, and ice, we will feel the Polar Express Sunday.

Between now and then, not much change. Mild and muggy weather continues today and tomorrow with a high at or just over 70 both days. Any showers should be very isolated, and fog and drizzle is likely, especially during the nighttime and morning hours.

Rain will increase tomorrow night into Sunday morning ahead of the cold air push, and Sunday will be a different kind of day. The rain should end during the morning, and it now looks like temperatures will fall into the 30s as far south as Birmingham during the afternoon. The sky will clear Sunday night as the dry, Arctic air settles into the region.

COLD DAY MONDAY: The latest GFS is showing a high of 40, and a low of 18 for Birmingham Monday. Sounds good to me, considering the depth of snow and ice north of here. At least the sky will be sunny for a change.

CHRISTMAS WEATHER: The cold air will modify quickly, and we begin to warm up Tuesday afternoon with a southerly flow becoming established. Then, a good rain event is shaping up for late Tuesday night and Wednesday. The 06Z GFS is a little slower with this, suggesting the best rain will hold off until Wednesday. The sky should clear Wednesday night.

Christmas Day looks dry and cool with a high in the 50s and a low in the 30s. Very standard late December weather for Alabama.

VOODOO LAND: Watch the Weather Xtreme video and you can see the evidence of an eastern U.S. upper trough forming after the arrival of the New Year with much colder weather here. We just aren’t able to provide details at this stage of the game. But, the cold air should be back as we get into 2009.

TWITTER: Don’t forget, you can follow our news and weather updates from ABC 33/40 on Twitter here. And, my personal Twitter feed is here if you want to keep up with my adventures in life. Twitter is a short messaging service you can receive via the web, cell phone, or IM.

WEATHER BRAINS: Don’t forget you can listen to our weekly 30 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. You can even listen here on the blog; look for the player on the top left.

Leaving early this morning for an in-house visit with Rick and Bubba in their palatial Vestavia studio… look for the next Weather Xtreme video here by 3:30 or so this afternoon. Enjoy the day!
