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 Tampa Bay, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 15, 1:50 PM EDT, 4 hours 10 minutes earlier.

Area forecast discussion, Jun 15, 1:50 PM EDT, 4 hours 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
150 PM EDT FRI JUN 15 2012

.SHORT TERM (TONIGHT - SUNDAY)...
THE COMBINATION OF A DECAYING SFC BOUNDARY OVER SOUTHERN FL...NE
FLOW PROVIDED BY PERSISTENT SFC HIGH PRESSURE NEAR THE EASTERN
SEABOARD AND ENOUGH LOW LEVEL MOISTURE WILL KEEP GOOD CHANCES FOR
THUNDERSTORMS AND SHOWERS LATE THIS AFTERNOON AND THROUGH THE
EVENING HOURS. MAIN AREAS AFFECTED BY SIGNIFICANT THUNDERSTORMS
SHOULD BE THE SOUTHERN ZONES OF THE CWA...BASICALLY THE INTERSTATE 4
CORRIDOR AND SOUTHWARD.

AN AREA OF LARGE THUNDERSTORMS HAS ALSO DEVELOPED ON THE OPEN
EASTERN GULF WATERS...WHICH IS NOW SLOWLY DRIFTING TOWARDS THE FL
WEST COAST. NHC WILL CONTINUE TO CLOSELY MONITOR THE PROGRESS OF
THIS SYSTEM...BUT TROPICAL DEVELOPMENT IS NOT ANTICIPATED AT THIS
TIME.

ONCE CONVECTION ACTIVITY ENDS TONIGHT...PLENTY OF CLOUD
COVER/CONVECTIVE DEBRIS SHOULD LINGER OVER THE AREA BUT WITH OVERALL
CONDITIONS BEGINNING TO BECOME DRIER AS HIGH PRESSURE ESTABLISHES TO
THE NORTH OF THE STATE. FOR THE REST THE WEEKEND...SUBSIDENCE AND A
DRIER AIRMASS WILL FILTER FROM THE NORTH AND BRINGING A BREEZY
NORTHEASTERLY WIND FLOW. RAIN CHANCES ACROSS THE AREA DROP TO
ISOLATED/20 PERCENT...AND EVEN DRIER ON SUNDAY. DAYTIME TEMPERATURES
WILL GO BACK TO A FEW DEGREES ABOVE NORMAL EACH DAY WITH HIGHS
CLIMBING INTO THE LOWER 90S WITH NEAR NORMAL LOWS IN THE 70S.

.LONG TERM (SUNDAY NIGHT - THURSDAY)...
U/L RIDGE WILL BEGIN TO BUILD OVER THE SOUTHEAST U.S. AND FLORIDA
MONDAY...WITH HEIGHTS GRADUALLY INCREASING THROUGH THE WEEK WITH
STRONG SUBSIDENCE OVER THE FORECAST AREA. SURFACE HIGH PRESSURE
WILL HOLD OVER THE MID ATLANTIC THROUGH THE PERIOD WITH EASTERLY
BOUNDARY LAYER FLOW EACH DAY. COMBINATION OF STRONG SUBSIDENCE...
DRY AIR ALOFT...SLIGHTLY LOWER SURFACE DEW POINTS...AND EASTERLY
FLOW WILL ALLOW DAYTIME TEMPERATURES TO CLIMB ABOVE CLIMATIC
NORMALS WITH SOME REGIONS REACHING THE MID AND POSSIBLY UPPER 90S.
MOS GUIDANCE ALTHOUGH ABOVE NORMAL...APPEARS SEVERAL DEGREES TOO
LOW WITH MAX TEMPS. DRY AIR ALOFT AND STRONG SUBSIDENCE OVER THE
FORECAST AREA WILL ONLY ALLOW FOR VERY LOW POPS EACH DAY...WITH
PREDOMINATELY DRY CONDITIONS THROUGH THE PERIOD.

&&

.AVIATION...
VFR CONDITIONS AT ALL TERMINALS EARLY THIS AFTERNOON. THUNDERSTORM
ACTIVITY NOW DEVELOPING FROM NORTH TAMPA BAY EASTWARD TO ORLANDO.
THIS CONVECTION IS EXPECTED TO EVOLVE SOUTH/SOUTHWEST...WITH ALL
TERMINALS INCLUDING ASSOCIATED TEMPOS FOR BRIEF THUNDER/MVFR
RESTRICTIONS. BRIEF LOWER VIS RESTRICTIONS POSSIBLE WITH HEAVIER
RAINS. ACTIVITY WILL DIMINISH DURING THE LATE EVENING. AREAS WITH
SUBSTANTIAL RAINFALL MAY EXPERIENCE IFR/MVFR FOG/CIGS LATE NIGHT.
POTENTIAL CAN BE REVISED ONCE RAINFALL PATTERNS ARE MORE CERTAIN.

&&

.MARINE...
A WEAKENING FRONTAL BOUNDARY ACROSS THE CENTRAL WATERS WILL CONTINUE
TO DRIFT SOUTHWARD WHILE BREAKING APART THROUGH SATURDAY. HIGH
PRESSURE BUILDS SOUTH ALONG THE EASTERN SEABOARD BEHIND THE FRONTAL
PASSAGE WITH WINDS SHIFTING TO THE NORTHEAST...THEN EAST AND
INCREASING LATER TONIGHT. EXERCISE CAUTION WILL BE RAISED FOR THE
NORTHERN WATERS FOR THE 4 PM FORECAST ISSUANCE...AND WILL DEFER TO
FOLLOWING SHIFTS TO EITHER EXPAND OR INCREASE TO ADVISORY IF
NECESSARY. EASTERLY WINDS WILL PREVAIL ON SUNDAY AND THROUGH EARLY
NEXT WEEK WITH AN EVENING SURGE OF WINDS LIKELY EACH DAY AS SURFACE
HIGH PRESSURE PERSISTS NORTH OF THE WATERS.

&&

.FIRE WEATHER...
HIGH PRESSURE WILL BUILD INTO THE FL PENINSULA FROM THE NORTH/NE
THROUGH THE UPCOMING WEEKEND...ALLOWING DRIER AIR TO ARRIVING ON DEEP
EAST TO NORTHEAST FLOW. THE DRIER AIR WILL HELP LIMIT
AFTERNOON/EVENING THUNDERSTORM ACTIVITY TO ONLY ISOLATED TO WIDELY
SCATTERED ACTIVITY...WITH BEST CHANCES FOR RAIN OCCURRING FROM TAMPA
BAY SOUTHWARD ALONG THE COAST. DESPITE THE DRIER AIR ARRIVING...
CURRENTLY DO NOT ANTICIPATE ANY SIGNIFICANT AREAS OF CRITICAL
RELATIVE HUMIDITY VALUES THROUGH AT LEAST SUNDAY.
