Warmer for the Weekend

Sat, 02/07/2015 - 08:27

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.

If you like sunshine and a warming trend, you will like today. We have started the day out on a chilly note with morning lows dipping back into the 20s once again. But with a clear sky today we should see highs climbing nearly 35 degrees with highs reaching the lower and middle 60s across Central Alabama.

The good weather continues into Sunday, but we will see more clouds as clouds increase ahead of another cold front that is expected to traverse Central Alabama on Monday. Rain chances on Monday with the front will be low as most spots stay dry, but you might see a little rain. The cool down will last into Tuesday, but we should see a nice warmup by Wednesday as sunshine returns in full force and we see highs reach back into the lower 60s.

A very strong trough will dig into the eastern US Thursday plunging us back into cold weather for the end of the week and the start of next weekend. Looks like we will see mainly clouds with this system, too, but there will be some chance for rain as moisture again remains limited.

The long wave trough position becomes established over the eastern third of the US, so we are going to stay cold as we end the week ahead and move out into the first days of voodoo country. It looks like Week 2 or voodoo land will be dominated by the trough over the eastern third of the country. The GFS even shows some potential winter mischief around the 17th of February as the pattern remains cold. But we should see a warmup by the end of Week 2 as ridging replaces the deep trough around the 21st and 22nd.

FEBRUARY CAN MAKE YOU SHIVER: Some temperatures just before daybreak…

Black Creek (just northeast of Gadsden) 13
Valley Head 14
Fort Payne 16
Gadsden 18
Cullman 18
Concord 18
Haleyville 18
Center Point 21
Fayette 22
Bessemer 22
Birmingham 22
Anniston 22
Tuscaloosa 25

The good news is that we warm up nicely today with a bright sunny sky, and most communities will see a high in the mid 50s this afternoon.

WEEKEND WARM-UP: Expect another sunny day tomorrow with a high in the low 60s, and we reach the mid 60s Sunday afternoon with a mix of sun and clouds. A clipper will pass northeast of Alabama Sunday night, dragging a cold front through here. This could squeeze out a few sprinkles Sunday night or Monday morning, but it looks like most communities won’t get enough rain to measure.

NEXT WEEK: Lots of sunshine Tuesday and Wednesday; the high Tuesday will be in the upper 50s, followed by mid 60s Wednesday. Then, a cold front passes through early Thursday morning, followed by colder air Thursday and Friday when highs drop into the 40s. Friday morning will be cold with a low down into the 20-25 degree range, with upper teens for colder pockets (much like this morning). See the Weather Xtreme video for the maps, graphics, and more details.

FIRST ALERT STORM TEAM TOUR: Our annual severe weather awareness tour across Alabama rolls along; we will be in Winfield Tuesday evening of next week. Just drop by anytime from 4:00 until 6:30… you can watch me do weather live on ABC 33/40, get some free stuff to take home, and have a chance to win several NOAA Weather Radios we will be giving away. If you need your weather radio programmed or checked, bring it by and we will be glad to help.

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.

Dry Through The Weekend

Thu, 02/05/2015 - 13:18

**No afternoon Weather Xtreme video today… we are on the road to Cedar Bluff for tonight’s weather tour stop**

SUNNY, BUT COLD: Nothing but severe clear across Alabama this afternoon, but temperatures are only in the mid 40s with a chilly north wind averaging 10-20 mph. Tonight will feature a pretty good freeze; most places around here will see a low between 22 and 26 degrees early tomorrow, with upper teens possible for the colder valleys of North Alabama.

TOMORROW THROUGH THE WEEKEND: Very nice weather with a warming trend. Sunshine in full supply tomorrow and Saturday; we reach the mid 50s tomorrow, followed by low 60s Sunday. Then, on Sunday, the GFS is printing a high of 67 degrees for Birmingham with a partly sunny sky. It will be one of the warmest days so far in 2015 (the warmest temperature so far this year is 68, recorded on January 19).

NEXT WEEK: A clipper system will pass northeast of Alabama Monday, and it might squeeze out a shower somewhere, but moisture will be limited, and it looks like most communities will stay dry. Then, slightly cooler air returns Tuesday with highs dropping into the 50s. The rest of the week looks rather quiet; a cold front could bring a shower or two by Thursday, but it doesn’t look like a big rain event.

Global models do suggest we will see a shot of colder air toward the end of the week, around Friday February 13 and Saturday February 14.

Cold, Blustery Winter Day

Thu, 02/05/2015 - 06:54

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.

RADAR CHECK: As expected, not much on radar early this morning. Just a few patches of drizzle and snow flurries in scattered pockets across North Alabama, and that will fade from the radar screen soon. Clouds this morning will give way to a bright, sunny afternoon, but the day will be breezy and colder. We won’t get past the low to mid 40s this afternoon, and a north wind of 10-20 mph will make it feel even colder.

Tonight will be feature a pretty good freeze; most communities will see a low between 22 and 26 early tomorrow; colder valleys could reach the upper teens.

FRIDAY AND THE WEEKEND: With sunshine in full supply tomorrow, we will see a high in the mid 50s. The warm-up continues through the weekend… Saturday promises to be a delightful day, with ample sunshine and a high in the low 60s. Then, mid 60s are likely Sunday afternoon with a mix of sun and clouds. We might consider a slight risk of a shower Sunday afternoon over the northern third of the state with an approaching clipper/front, but with very little moisture we won’t mention it for now.

NEXT WEEK: The clipper would bring a shower or two to North Alabama Monday, but the last few runs of the GFS have trended drier, showing only isolated showers. Then, the weather looks cool and dry Tuesday through Thursday with highs mostly in the 50s and lows generally in the 30s. A cold front arrives late in the week with some potential for a few showers, followed by colder air for the following weekend. See the Weather Xtreme video for maps, graphics, and more details.

NWS to NWS (almost)

Wed, 02/04/2015 - 23:12

Well, it was bound to happen one day. And it did happen just up the road from us on January 13, 2015. The National Weather Service (NWS) in North Little Rock, AR, station identifier KLZK, prepared their routine upper air run by blowing up the balloon, calibrating the radiosonde instrument, and tying off the balloon with a parachute to allow the radiosonde to come down safely. Finally, after all the preparation, the balloon and its instrument package were all set to release. About an hour before 00Z, the balloon took flight into the Arkansas sky. The run was pretty uneventful, and as you might expect, the package encountered a west to east flow of air from about 700 millibars, roughly 10,000 feet, all the way up to over 100 millibars, roughly 55,000 feet. The wind between 300 and 200 millibars reached a maximum velocity of about 100 knots or 115 mph.

Then with the atmosphere getting thinner and thinner, the balloon finally burst, and the radiosonde began its free fall back to earth slowed to a safe speed by a simple paper parachute. Like many radiosondes, it landed in a tree and was left dangling from a low hanging branch. And this is where it really became interesting. The tree branch was sticking out of a tree in the front yard of the NWS office in Memphis, TN, approximately 80 air miles from the launch site.

So without the aid of any guidance, the radiosonde flew from one NWS office to another. That was one smart radiosonde!! See the pictures below for a view of the radiosonde dangling from the tree and the Skew-T diagram showing the high speed flow of air. You just can’t make this stuff up.

-Brian-

PS Here’s an update to this story. It seems the radiosonde did not land where it was reported, but it did land close. The radiosonde launched from LZK actually fell in Bartlett, TN, which is only a couple of air miles from the NWS Memphis office. The radiosonde landed in Bartlett, and the person who found it brought it to the Memphis NWS office. So it was NWS to NWS (almost)!!
