A lot of technical jargon…but this says that the heavy rains may continue through the night…could be a dangerous situation.

.
SATELLITE ANALYSIS AND TRENDS…TRACKABLE CELL THAT WAS ACROSS MOBILE
COUNTY AROUND 2330Z AND HAD A NASA TRMM 10MI INSTANTANEOUS AREA AVG
MICROWAVE RAIN RATE OF 1.8″ WAS MOVING THRU CENTRAL ALABAMA COUNTIES
(CHILTON/SHELBY) PAST 15 MINUTES. CONVECTIVE BAND STILL REMAINING
SEPARATE WITH WESTERNMOST BAND E CENTRAL MS THRU CENTRAL TN BUT THEY
MAY TRY TO FUSE TOGETHER NEXT 3-4 HRS OVER NORTHERN ALABAMA INTO E TN.
JUST AS BIG OF AN ANALYSIS STORY THIS EVENING IS SURGE OF EVEN DEEPER
MOISTURE (2.5″/OVER 225% OF NORMAL/3-4 STANDARD DEVS ABOVE NORMAL) FROM
GULF OF MEXICO AND YUCATAN AND YOU CAN SEE IT ALSO IN GOES WATER VAPOR
LOOP AS A SUBTROPICAL JETLET OR MINI JET GETS INVOLVED AND NOSES INTO
FAR E LA/SE MS/SW ALABAMA AND MAYBE HELPING ORGANIZING THE EASTERN MOST
CONVECTION A BIT BETTER. UPPER LEVEL RIDGE TO THE EAST ALONG SE COAST
HOLDING FIRM…SO MUCH SO THAT PWAT MIN ACROSS CENTRAL GA/SC AND HELPING
TO TIGHTEN PWAT MOISTURE AXIS CENTERED SE MS THRU W CENTRAL TO CENTRAL
ALABAMA NORTH/NE THRU EASTERN TN. SUCH HIGH MOISTURE THAT IS NEAR RECORD
BREAKING FOR THIS TIME OF YEAR WON’T NEED MUCH OF TRIGGER/FOCING DEVICE
TO PRODUCE EXCESSIVE RAINFALL, AS SHOWN BY TRMM RAIN RATE PASS WHILE
CELL WAS MOVING THRU MOBILE COUNTY AT AROUND 2330Z. WILL HAVE TO WATCH
S MS…SW ALABAMA…CENTRAL AL INTO
N ALABAMA FOR THE NEXT FEW HRS FOR ENOUGH RAINFALL THAT MAY CAUSE FURTHER
PROBLEMS THRU 05Z. AND DRY AIR BLOCK TO THE EAST ALONG WITH UPPER LOW
WAY OUT WEST CONTINUING TO DROP SOUTH THRU E AZ/W NM INSURES VERY SLOW
PUSH EASTWARD OF CONVECTIVE BANDS…SO INTERESTING SCENARIO OF HVY RAIN
BANDS THAT MAY COME TOGETHER WILL BE WATCH NEXT SEVERAL HRS.
