Multiple tornadoes on the ground in Winston County at this time. Damage has been reported. Anyone in areas northwest of a line from Aliceville to Jasper to Cullman needs to be on high alert for the next two hours. In Tuscaloosa and Birmingham, we will probably see action later tonight,...

As JP noted in his blog a little while ago, SPC is considering issuing a tornado watch for parts of west Alabama in the next hour or so. The above radar picture shows reflectivity (left) and velocity (right) in Mississippi. Notice that the wind shear is sufficient so that many... Continue reading

The above map shows dewpoints, the best measure of moisture in the atmosphere. Notice that there is a sharp contrast just north of I-20, with dewpoints in BHM and TCL in the 60s, but dewpoints in Cullman and Huntsville in the 40s. That pseudo-warm front will continue to move north... Continue reading

The line of intense thunderstorms is right on time, crossing into NW Alabama as I write this blog. The winds out ahead of the storms have been very significant, with winds gusting to 39 mph at BHM airport and close to 50 mph on some of the higher ridges in... Continue reading

The water vapor satellite image at the top of this page shows the massive storm system affecting a large part of the central and eastern U.S. this afternoon, with a big swirling low pressure area over North Dakota and rain and storms from Michigan to Texas. This is the type... Continue reading

A large upper-level storm system is spinning over the northern U.S. early this morning, and the divergence out ahead of it will cause pressures to fall rapidly over Arkansas, Mississippi, Alabama, and western Tennessee today. The high pressure area to our east will not move out quickly, so a large... Continue reading

1. Statistics A very large part of north and east Alabama are now in stage 4 drought conditions - the worst possible on the scale, including Birmingham, Tuscaloosa, Anniston, and Gadsden. Parts of northwest Alabama got a little bit of rain Friday night, and BHM got 0.01" of rain, after... Continue reading

A cold front is approaching Alabama from the west, and a line of showers and thunderstorms is moving along that front from Arkansas into eastern Texas. The problem is that, as it has been with all major weather systems over the past two months, the best dynamics in the atmosphere... Continue reading

A cold front will move through Alabama early tomorrow morning, dropping temperatures out of the 80s into the 70s during the day, with lows maybe in the upper 40s this weekend. However, with most of the upper-level dynamics moving off to the NE, any rain along the front will be... Continue reading

(Nelson Brooke, Black Warrior Riverkeeper) The photo above is from the upper, naturally-flowing parts of the Locust Fork of the Black Warrior River. It is a sad one, and there are many other dried up creeks, branches, and streams all over north and central Alabama. In addition, our controlled lakes... Continue reading

At noon, BHM was already at 86 degrees, and we should easily tie or break the record high for today of 88. I wrote a blog in late September about the long, hot summer we have had yet without any days over 100, and I will summarize the summer (and... Continue reading

The above radar pictures show rainfall (left) and wind direction (right), and the eye of Matthew is quite visible. The center of Hurricane Matthew continues its slow move about 25 miles off the east coast of Florida, much as it has been doing for the past 12 hours or so.... Continue reading

The NEXRAD radar at NWS Melbourne, FL is detecting winds of 140 mph at about 3,000 feet altitude 25 miles east of Cape Canaveral. If those winds rotate onshore, even with reduction due to altitude and friction, the coastline could see wind gusts of 100 mph in the next few... Continue reading

Notice that the small, older eye of the hurricane is being replaced by a larger eye as the small one wraps up and gets absorbed into the new one. The NOAA hurricane hunter aircraft found two eyewalls earlier, one 9 miles across and the other 70 miles across. This is... Continue reading

Hurricane Matthew is on the move this afternoon, moving NW at 10 mph toward the east coast of Florida. The terrain of Cuba and Haiti did weaken the storm a little, as friction with the land disrupted the circular flow and allowed some of the higher pressure air to flow... Continue reading

This summer has been a hot one. I don't think anyone would deny that. It has also been rather humid, making air conditioners work harder (their energy goes into cooling and removing moisture from the air and when the air is more humid, more energy has to go into removing... Continue reading
