FLORIDA SEVERE WEATHER UPDATE

The atmosphere is constately changing.  Severe weather Outlook graphics showing  Central Florida as 'Enhanced' chance for severe storm development now. 

This is more than likely due, because all that rain and storms have been training over this area since yesterday.

This area yesterday was under a 'Slight' chance for severe storm development.

I have notice on this morning satellite that the colder cloud top have warned over night.  This may be due to lack of heating from the day. 

Humidity levels are now rising as the sun heats the surface and we could see cooling off the clouds again as they tower upward and this means possibility of damaging winds, severe storms and isolated water spouts and tornado...

Stay alert today Central Florida and Southern Florida this evening in case severe weather Increases... RTW

...STRONG COLD FRONT WILL IMPACT THE KEYS THURSDAY THROUGH 
FRIDAY NIGHT...

A strong cold front is expected to blast through the Florida Keys
and adjacent coastal waters late Thursday or Thursday night. This
front is expected to bring multiple weather hazards to the Keys 
from Thursday morning through Friday evening, including strong to 
severe thunderstorms, strong winds on land with gales likely on 
the coastal waters, and possible coastal flooding on the Gulf and 
Bayside.

The main weather event is expected to occur from Thursday morning
through Friday night. The potential for strong to severe 
thunderstorms ahead of the cold front will be highest from 
Thursday into Thursday night. These thunderstorms may organize 
into a squall line which could move through the Keys during the 
late afternoon or evening hours. The primary hazards with any 
thunderstorms will be strong, gusty and shifting winds along with 
lightning strikes. Some of the thunderstorms on Thursday or 
Thursday night could become severe with damaging winds and large 
hail. Isolated waterspouts will also be possible, and there is a 
slight risk for tornadoes as well. The Storm Prediction Center 
continues to include all of South Florida and the Keys within a 
severe thunderstorm risk area for Thursday into Thursday night.

On land, gusty south to southwest winds will increase to 20 to 30
mph on Thursday. Strong sustained west winds around 30 mph with 
gusts near 40 mph are expected on Friday, with winds possibly 
reaching these speeds beginning Thursday night. This will prompt a
Wind Advisory.

These persistent and strong westerly winds will cause Coastal 
Flooding impacts on the Gulf and Bay side communities along the 
length of the Florida Keys. The maximum water levels will likely 
occur along the shores of Blackwater and Buttonwood Sounds, 
around the time of high tide late Friday afternoon. In these 
areas total water levels may reach 3 to 4.5 feet above mean sea 
level Friday into Friday night. Coastal flood warnings and
advisories may be required.

Mariners should continue to prepare for a high impact weather 
event for Thursday through Friday night, and time is running 
short. Small Craft Advisories will certainly be needed during this
event beginning Thursday as strong southerly breezes develop. 
Winds will become westerly and increase to near gale behind the 
front Thursday night, lasting into Friday night. There is an 
increasing likelihood that Gale Warnings will be needed for much 
or all of the Keys coastal waters. A Gale Watch is now in effect 
for all Keys coastal waters. Very large seas are also expected 
with this event, peaking on Friday at 10 to 17 feet across the 
Straits of Florida and deep waters of the southeastern Gulf of 
Mexico, 5 to 8 feet in Hawk Channel inside the reef, and 4 to 8 
feet across the Gulf waters inside five fathoms.

Listen to NOAA All Hazards Weather Radio for the latest weather
information, including possible warnings. In addition, please 
remember to turn on your radio's severe weather tone activation 
feature. Also visit your Florida Keys National Weather Service on
the web at www.weather.gov/keywest.

FLORIDA SEVERE WEATHER UPDATE

Storm Prediction Center has upgraded a portion of Florida "Enhanced" chance for severe weather along the east coast (see map).  The other portion of Florida from Central Florida including south to the Florida straits is still under a "slight" chance.

Looks like the first batch of rain and storms could arrive over night and and the second half Thursday.  Stay alert!

THERE IS STILL A POTENTIAL FOR HEAVY RAINS AND SEVERE STORMS OVER FLORIDA THURSDAY

There is still a chance for the possibility of strong to severe storms with damaging winds, heavy rains and isolated tornadoes on Thursday evening.

A trough moving across the Gulf and a bit of Caribbean moisture is helping to energize an area of showers and storms over the southeast Gulf.  This trough will sweep this disturbance across Florida with the potential for heavy rains, damaging winds and isolated tornadoes.

This will more than likely occur late Thursday and over night so if the severe weather materializes you need to have your NOAA weather radio set to alert or have your cell phone near by so alerts will be heared when issued via cell phone network emergency alert system...RTW
