Severe Weather Alert Descriptions

 Special Statement  Statement as of 4:17 PM CDT on July 22, 2014


... Cluster of strong thunderstorms moving west affecting Pearl River
County... Hancock County... St. Tammany Parish...

At 416 PM CDT... National Weather Service Doppler radar indicated a
cluster of strong thunderstorms near Picayune... or about 5 miles
southeast of Picayune... moving west at 5 mph.

The cluster of strong thunderstorms will affect areas in and
around... Picayune

The primary threats from these storms are frequent lightning and wind
gusts to near 40 mph... which could down tree limbs and blow around
unsecured small objects. Seek shelter in a safe home or building
until these storms have passed.

These storms could produce rainfall amounts of one to two inches in a
short period of time... resulting in ponding of water around low lying
roadways. Remember... do not drive your vehicle into water covered
roadways. The depth may be too great to allow a safe crossing.

Be prepared to take quick action if a warning is issued. Stay tuned
to NOAA Weather Radio or your favorite local media outlets for
further details or updates from the National Weather Service.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
330 PM CDT Tuesday Jul 22 2014 


Short term... 


Drier air from the 12z sounding this morning working its way out 
as an upper low moves in from the east. Shower and thunderstorm 
activity developed first on the southshore earlier this morning 
and continues south of the metropolitan area this afternoon. Additional 
shower and thunderstorm development is occurring now across the 
northeastern parts of our area including Pearl River County and 
Washington Parish as storms develop and rotate around the upper 
low. Some of the storms today have been capable of producing heavy 
rainfall amounts in a short period of time. Activity is expected 
to wane as we move into the late evening hours. 


Tomorrow...the upper low continues to the west and begins to 
stretch out eventually weakening by Thursday and continuing to the 
southwest. Rain chances remain near normal tomorrow aided by the 
upper low but quickly drop back down below Summer norms on 
Wednesday night and Thursday. 


Long term... 


Next week models still point to an active jet pattern and an upper 
trough that will dig across the the eastern part of the country late 
in the week. This will result in a weak front being pushed into the 
southeast and lower Mississippi Valley toward the end of the week 
before stalling out. That front is not likely to be a weather 
maker in our area it struggles to make a progression southward. 
The trough begins to deepen by Sunday and into early next week 
which may push another cold front closer to the Gulf Coast early 
next week...although it remains to be seen if either front has any 
real impact on our weather outside of our norms. 


&& 


Aviation... 


Any lingering convection after 00z should quickly dissipate with the 
setting sun. Overall...expect to see VFR conditions prevail at all 
terminals with only some lingering middle to high level clouds tied 
into an upper level low sitting over the area. This upper level low 
should provide enough forcing to spark off another round of 
scattered convection after 16z tomorrow. Have included thunderstorms in the vicinity wording 
at all of the terminals to reflect this convective risk from 16z 
through the remainder of the forecast period. There will be another 
cumulus field ranging from 3000-5000 feet over all of the terminals 
through the day. Outside of the convection...no significant 
operational impacts are expected. 


&& 


Marine... 


Fairly tranquil conditions expected across the marine areas 
outside of any shower and thunderstorm activity as high pressure 
builds in over the coastal waters. Winds will remain generally in 
the 5-10 knot range with waves of 1-2 feet across most of the 
waters. 


&& 


Decision support... 


Dss code...green. 
Deployed...none. 
Activation...none. 
Activities...slurry support.
