Thunderstorms with heavy rain continue from Tuscaloosa eastward into southern parts of BHM, near Hoover and Pelham. More heavy rain is approaching I 65, so the commute may be rough headed toward alabaster and Helena too. See Jill's post below for more info on the storms. A big time Cold... Continue reading

I guess we could say the first cold front of fall 2014 is on the way, but we had 4 separate cold fronts during July and August that dropped temperatures way down, 3 of them into the 50s, so did the active jet stream of the cool season ever really... Continue reading

Check out the high res radar picture this afternoon. No rain, so NWS can put it in extra sensitive mode, looking for clouds, dust, etc. Notice the SE to NW oriented streaks on radar. They are due to wind shear at low levels producing looping, or vertically rotating, thermals. Where... Continue reading

In my first blog on humidity, found http://birmingham.raycomweather.com/2014/08/humidity-part-1.html, I discussed relative humidity, dew point, mixing ratio, and other neat stuff about the amount of water vapor actually in the air (it may be more than you think). This blog will have some other neat facts about humidity and how it... Continue reading

It feels much nicer outside today than it has! It's not as hot, and also importantly it's not as humid. On Sunday morning, in an area outdoors the size of a 2,000 square foot house, there were 3.2 gallons of water vapor in the air! Today, in that same volume,... Continue reading

They call them lazy, dog days of summer. My beagle, Jack, apparently feels that way. He normally is emphatic, or at least up, when he howls at fire trucks or other sirens he hears on US Highway 11. Last night he was lying on his back and didn't even bother... Continue reading

In a recent blog, I discussed the fact that this heat wave will probably not break any records, and we may not even reach 100 degrees. Read that blog at http://birmingham.raycomweather.com/2014/08/heat-wave-coming-but-not-historic.html But, with humidity and high temperatures between 95 and 98 degrees, heat index values may go above 105, so...

You've heard a lot of talk about the coming heat wave. It really started today, as it's 93 in BHM now. But, will this be a record-breaking heat wave, or will we even reach 100 degrees? Probably not. But, as I point out in the blog above, we are not... Continue reading

Strong thunderstorms are approaching BHM. When they passed my location on tghe Warrior River (eastern Walker county), I got about 8 total lightning strikes within 1 mile, and a couple within 250 yards. This is serious...any football/band practices need to hold off until this is over. High wind too. Check... Continue reading

Probably not, but some very pleasant air for August will move in tonight and tomorrow, and temperatures will hold in the 80s tomorow and Thursday, with mostly sunny skies and a north breeze! We'll drop down into the lower 60s in parts of central Alabama, but record lows are way... Continue reading

I wrote a blog two or three weeks ago about the rarity of having three cold fronts in July. Temperatures dropped into the 50s in central Alabama three separate times. Now, the first cold front of AUGUST is coming in tomorrow. This one is not quite as strong as the... Continue reading

In an earlier blog, I pointed out that our air is coming from Lake Michigan today, and we expect record lows tonight. In this blog I want to talk about how rare it is to have three separate bona fide cold fronts in the month of July that bring us... Continue reading

It's almost like the active pattern of upper-level troughs and cold fronts delivering cold air into the U.S., that started back in January, has never fully come to a stop. A cold front will come through Alabama tomorrow, bringing more beautiful, unusually mild weather for July by Tuesday and Wednesday.... Continue reading

A couple of fairly small but intense storms, possibly related to the BHM heat island, have been moving very slowly through Tarrant City, Ketona, Sun Valley, and parts of Center Point and Roebuck for the past hour or more. Another storm has been near Gardendale and Fultondale. The BHM airport... Continue reading

Another area of rain and storms is located over Mississippi and extreme west Alabama this morning. So far, these storms do not look severe, but they will likely intensify some as they move into the unstable air over central Alabama. With dewpoints in the lower 70s, any rise in temperatures...

Standing on my pier on the Warrior river early this morning before bed, no visible lightning, no thunder. Just a waxing moon and bugs. Radars to the west paint a different picture. One line of storms in central Mississippi. .. Another from west Tennessee into north Mississippi. The ones in... Continue reading

Blobs of severe storms, with potential for damaging winds, are all over north AL, north MS. A weak upper disturbance is moving by to our north, and there is actually a little bit of low level wind shear for storm rotation, in adition to deep shear for storm organization overnight....

The way these storms are moving, if you work downtown/Homewood/Hoover, you can probably still get home ahead off the torrential rain if you live south of town. DRiving in these storms still be very difficult. The training and slow movement may lead to flash flooding. Dr Tim Coleman Continue reading
