The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Apr 15, 3:41 AM CDT, 18 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
341 AM CDT TUE APR 15 2014
.SYNOPSIS...
LIGHT RAIN SHOWERS WILL CONTINUE MAINLY OVER NE AL IN THE POST
FRONTAL ZONE OF AN EXITING SFC ARCTIC COLD FRONT. THE UPPER TROUGH
AXIS PUSHING THIS FRONT IS CURRENTLY MOVING EAST ACROSS THE MS RIVER
VALLEY. TRAILING LOW STRATUS IS FOLLOWING THE FRONTAL PASSAGE WITH
GUSTY NORTHWEST WINDS NOTED OVER MS/AR/W TN. THIS COLD AIR ADVECTING
AND THE CHANCE FOR BELOW FREEZING TEMPERATURE TONIGHT WILL BE THE
MAIN STORY FOR THE FORECAST. MEANWHILE, AN AMPLIFIED RIDGE IS
BUILDING OVER THE CENTRAL ROCKIES, AS A SUBTROPICAL FETCH EXTENDS
FROM THE EXITING EAST COAST TROUGH WESTWARD OVER THE CENTRAL PACIFIC.
FURTHER NORTHWEST, THE NEXT MID-LEVEL SHORTWAVE TROUGHS ARE LINING UP
OVER THE GULF OF ALASKA.
SL.77
&&
.SHORT TERM (TODAY THROUGH THURSDAY)...
DEEP CAA FROM THE NORTHWEST TERRITORIES OF CANADA WILL BE THE MAIN
IMPACT TODAY WITH A STRONG PRESSURE GRADIENT YIELDING NORTHERLY WINDS
OF 15 TO 25 MPH WITH GUSTS TO 35 MPH LIKELY, ESPECIALLY OVER THE
CUMBERLAND PLATEAU. THE SFC HIGH PRESSURE CENTER WILL SLOWLY SHIFT
EAST FROM NORTH TEXAS OVER THE NEXT FEW DAYS. TEMPERATURES WILL ALSO
BE MUCH COOLER THAN THE PAST WEEK OR SO WITH TEMPERATURES CURRENTLY
IN THE MID TO UPPER 40S BEHIND THE COLD FRONT AND UPPER 50S AHEAD OF
THE COLD FRONT. WIND SPEEDS REACHING THIS STRENGTH WILL LARGELY
DEPEND ON THE EXPECTED DISSIPATION OF THE LOW STRATUS IN THE WAKE OF
THE FRONT. RIGHT NOW, THE CLEARING LINE IS JUST WEST OF THE MS RIVER
AND SLOWLY SHIFTING EAST. AM NOT CERTAIN WE WILL ACTUALLY MEET
CRITERIA FOR A WIND ADVISORY HERE, BUT WILL GO AHEAD AND ISSUE ONE
SINCE WE ARE CLOSE ENOUGH TO CRITERIA. OVERALL, WITH TEMPERATURES
HOLDING STEADY IN THE UPPER 40S TO LOW 50S, THE COLD NORTHWEST WINDS
WITH THIS ARCTIC AIRMASS WILL DEFINITELY MAKE IT FEEL LIKE WINTER
AGAIN.
WINDS WILL THEN DIMINISH THIS EVENING WITH A CLEAR SKY EXPECTED AS
THE SFC HIGH PRESSURE SYSTEM CENTER MOVES ACROSS TN/OH RIVER VALLEYS.
THIS WILL ALLOW RADIATIONAL COOLING TO OVERTAKE MOMENTUM MIXING,
TRANSLATING TO TEMPERATURES DROPPING BELOW FREEZING FOR THE FIRST
TIME SINCE MARCH 26TH AND AREAS OF FROST. TEMPERATURES ARE EXPECTED
TO BE AT OR BELOW FREEZING BY 06-07Z (1AM-2AM CDT) TONIGHT THROUGH
12Z (7AM) TOMORROW MORNING. THUS, WILL BE ISSUING A FREEZE WARNING
FOR TONIGHT.
THE SFC HIGH PRESSURES SYSTEM WILL QUICKLY SHIFT EASTWARD ON
WEDNESDAY ALLOWING SFC FLOW TO VEER TO THE SOUTH AND TEMPERATURES TO
RECOVER INTO THE 60S. THE UPPER FLOW PATTERN ACROSS THE SOUTHEAST
THEN SHIFTS TO THE SW WITH A NORTHERN STREAM MID-LEVEL SHORTWAVE
TROUGH MOVING ACROSS THE CENTRAL AND SOUTHERN PLAINS ON THURSDAY.
ANOTHER SOUTHERN STREAM DE-AMPLIFIED MID-LEVEL SHORTWAVE TROUGH IS
ALSO EXPECTED TO MOVE EAST ACROSS NORTHERN MEXICO AND GOMEX PARALLEL
TO THIS WAVE. TEMPERATURES WILL CONTINUE TO WARM WITH THE SOUTHERLY
FLOW IN PLACE WITH DAYTIME HIGHS ON THURSDAY CLOSE TO 70 BUT AREAS
OVER NE AL/N GA MAY BE UNDER THE INFLUENCE OF COLD AIR DAMMING
ADVECTING WESTWARD FROM THE LEEWARD SIDE OF THE APPALACHIANS. SO,
TEMPERATURES WILL LIKELY BE SOMEWHAT COOLER OVER NE AL.
.LONG TERM (THURSDAY NIGHT THROUGH MONDAY)...
THE MERGING OF THE PREVIOUSLY MENTIONED TWO WAVES IS EXPECTED TO
BRING A SLIGHT CHANCE FOR SHOWERS ON THURSDAY NIGHT. ISOLATED
THUNDERSTORMS WITH A CHANCE FOR SHOWERS ARE ALSO POSSIBLE ON FRIDAY.
LITTLE IN THE WAY OF INSTABILITY IS PRESENT AS THE NORTHERN STREAM
TROUGH BECOMES THE DOMINATE OF THE TWO WAVES AND MOVES SOUTHEAST
ACROSS S GA/FL. DID REDUCE POPS ON FRIDAY NIGHT AS IT APPEARS THAT
THE TROUGH WILL HAVE CLEARED THE TN VALLEY (AT LEAST ACCORDING THE
ECMWF), BUT HAVE LEFT ISOLATED SHOWERS IN THE FORECAST TO ACCOUNT FOR
SOME VARIABILITY WITH THE MODEL GUIDANCE.
THE REST OF THE WEEKEND SHOULD BE WARM AND DRY UNTIL ANOTHER
SOUTHERN STREAM MID-LEVEL SHORTWAVE TROUGH AND A DEEPENING NORTHERN
STREAM TROUGH BRINGS THE NEXT CHANCE FOR PRECIPITATION ON MONDAY AND
TUESDAY. KEPT MAINLY SEASONABLY WARM TEMPERATURES FOR THE EXTENDED
FOR NOW, THOUGH SOME COOLING COULD BE POSSIBLE ON TUESDAY IF MODEL
CONSENSUS ON A FRONT MOVEMENT PREVAILS IN LATER FORECAST PACKAGES.
