The temperature reached a high of 84 degrees around 3 pm yesterday afternoon in BHM, then dropped some due to a line of storms. It sat in the 70s for a while, then dropped more as storms moved through last night. But, the first of a big drop started early... Continue reading

(Uncalibrated radar estimated rainfall) One thing we got yesterday and overnight was a lot of rain that we needed. The map above shows uncalibrated radar estimates from the BMX radar. Most of central Alabama got 2-3" of rain. Some actual (gauge) rainfall totals included BHM 2.17", Jasper 2.34", Moody 3.30",... Continue reading

The main squall line is moving more slowly than I thought earlier. It looks like it won't make it to TCL until around 9 pm and BHM around 1000 pm or so. I have circled two storms of slight concern. One is in Chilton county...out ahead of the main line.... Continue reading

The main line of storms is crossing the Alabama/Mississippi border right now. NWS has issued severe thunderstorm warnings for Lamar and Pickens counties. A tornado watch continues until midnight. The storms I circled earlier, the indivudual ones out ahead of the main line that had the greatest tornado potential, have... Continue reading

I circled the storms of most concern right now. It's often these isolated cells out ahead of the main line of storms that produce tornadoes. Tornado warnings are in effect for the 2 northern ones in Marion County, and in Lauderdale, Colbert, Franklin counties. It seems like the greatest risk... Continue reading

A strong cold front and associated upper-level system are approaching Alabama this afternoon. This front means business, with southerly flow making it feel like summer over Alabama (temperatures in the 80s, dewpoints in the upper 60s). Behind the front in Kansas, it is in the 30s during the day. The... Continue reading

There were many reports of large hail out of the storms over north Alabama yesterday afternoon/evening, mainly in areas from Cullman north. However, we at Fox 6 received a lot of viewer pictures like the one above as storms moved through Cullman between 530 and 630 pm. Is that just... Continue reading

A strong upper-level disturbance associated with cold air aloft is moving toward NW Alabama this afternoon. With the cold air aloft, and dew point temperatures back to near 60 at the surface, the air has become a little bit unstable, and there is a little wind shear too. The combination... Continue reading

The storms are moving on to the east, but the cold front hasn't quite gotten here yet. It is currently in west Tennessee, and will arrive here around sunset. Winds will become very gusty this evening, northwest at 10-20 mph, as temperatures fall through the 60s. By tomorrow morning, it... Continue reading

Tomorrow is October 1, the beginning of our big transition month into the cool season. And a large cool air mass is already developing over Canada and the northern U.S. Temperatures at mid afternoon are only in the 50s over much of western Canada and the northern U.S. Some observations...

Sometimes, when a high pressure area gets centered in the NE US or SE Canada, and the air is too cool and stable to flow over the Appalachian Mountains, it starts flowing down the east side of the mountains and all the way into Alabama. Notice in the map above... Continue reading

You've probably noticed that the days are getting shorter. Today the sun will set at 6:42 pm in BHM. Just three weeks ago at Labor Day, it was setting after 7:00 pm. The sun comes up later too, with sunrise tomorrow not until 6:37 am. Back in July, sunsets were... Continue reading

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
