What forecasters said that day

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

NWS Miami, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 15, 3:42 PM EDT, 57 minutes earlier.

Area forecast discussion, Apr 15, 3:42 PM EDT, 57 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
342 PM EDT MON APR 15 2013

.DISCUSSION...ACTIVE CONVECTION ONGOING AND THINKING IT COULD REV
UP EVEN MORE OVER THE NEXT COUPLE OF HOURS. STRONG HEATING HAS
LEAD TO SBCAPE OF 3000 J/KG IN THE LAKE OKEECHOBEE AREA WITH HIGH
CAPE EXTENDING ACROSS PALM BEACH AND BROWARD. CONVECTION IS FIRING
ALONG THE GULF SEA BREEZE AND ACARS DATA CURRENTLY SHOWS A
WESTERLY STEERING FLOW, SO THE STORMS ARE EXPECTED TO MOVE INTO
THE EAST COAST METRO AREAS WITH A CONTINUED THREAT OF ISOLATED
SEVERE THUNDERSTORMS. PALM BEACH AND BROWARD HAVE THE HIGHEST
INSTABILITY RIGHT NOW. THIS COULD BE THE AREA OF A LOCAL ENHANCED
RISK FOR ISOLATED SEVERE. STAY TUNED FOR POSSIBLE ADDITIONAL
WARNINGS THROUGH EARLY THIS EVENING. CELLS SO FAR THIS AFTERNOON
HAVE BEEN PRODUCING WET MICROBURSTS AS PER THE TERMINAL DOPPLER
RADARS. A 61 MPH WIND GUST WAS RECORDED IN THE REDLAND OF MIAMI-
DADE COUNTY, WITH DAMAGE TO A CARPORT, ALONG WITH NICKEL HAIL.

AFTER THE CONVECTION WANES WITH THE LOSS OF DAYTIME HEATING THIS
EVENING, THEN TRANQUIL WEATHER IS EXPECTED OVERNIGHT. A RIDGE IS
EXPECTED TO PUMP UP OVER SOUTH FLORIDA, ALONG WITH DECREASING
PWATS. THE RESULT OF THIS IS THE EXPECTATION OF A DRIER WEATHER
REGIME IN AN EAST-SOUTHEAST WIND FLOW TOMORROW THROUGH FRIDAY.
HOWEVER, THE GULF SEA BREEZE COULD STILL TRIGGER ISOLATED
AFTERNOON TSTORMS TOMORROW.

IT CONTINUES TO LOOK LIKE THE UPCOMING WEEKEND COULD BE WET AND
STORMY AS AN AMPLIFIED TROUGH MOVES INTO THE SOUTHEASTERN UNITED
STATES. TOO BUST IN THE NEAR TERM TO LOOK TOO CLOSELY IN THE
EXTENDED AND HAVE KEPT INHERITED FCST, BUT POPS WILL NEED TO BE
INCREASED SHOULD THIS WET TREND CONTINUE.

WITH SEAS LESS THAN 4 FT.
