Alabama Weather Update

Windy conditions continue across Central Alabama as we move into the late afternoon hours.

The NWS advises that they will be upgrading the Lake Wind Advisory to a Wind Advisory for the overnight hours. Strong southeasterly winds have averaged some 15-25 mph and gusted at times over 30 mph. We may see gusts to 40-45 mph tonight even outside storms.

The main squall line is now near the Mississippi River over eastern Arkansas and approaching western Tennessee and Mississippi. The storms are beginning to really show signs of rotation and numerous tornado warnings are in effect over eastern Arkansas and northeastern Louisiana.

A late check of storm reports shows no recent tornado reports. One was reported a short time ago near Crossett in Ashley County, AR. The NWS Jackson says they show strong signs of a tornado near Hamburg.

Thunderstorms have developed in the warm air advection flow over western Mississippi. Severe thunderstorm warnings have been issued for coutnies in the Mississippi Delta, but the NWS Jackson advises that the main action will come with the main line.

Some folks have been questioning how we can have severe weather with dewpoints in the 30s and 40s. We can’t. But strong advection of warm air is occurring over western Mississippi ahead of the main line. The low level jet is just hosing moisture into the area, creating a narrow tongue of instability that will shift eastward overnight.

An interesting note…the storms over Arkansas and Misssippi are moving at 60 to over 80 mph at times! That shows the strength of the wind fields.
