Mild cold front coming in

Beautiful sunrise this morning. Isn't it said if the morning is red sailors dred?
Well shortly after the sunrise the sky became overcast and light precept started falling. There is a mild cold front coming in nothing to severe temp wise, and weather wise.

Winds are still coming in from the south but once this front moves across winds will change and come from the north. The difference will be at night, with temps dropping into the high 40's to lower 50's depending on where you are. Daytime temps will be just a little bit cooler.
There is a slight risk of severe weather for the folks on the east coast of our country( eastern Carolina's has a 2% chance of tornadoes) but that's about it.
SDS at this time of year is strong with all of us weather geeks.
Come on spring!!!
Tomorrow looks to be a perfect outside day!
Well that's all got for now Have a great weekend enjoy the weather and get out and do something!!!
Jess.. :-)

HAIL (3/4 inch or greater)

Hail can cause significant damage to your vehicle, break windows and damage roofs of homes and businesses.
Hail can cause significant bodily injuries such as broken bones and even blindness if wind blown.
Softball (4.5 inches) sized hail was reported in Lake Wales, Florida on March 30, 1996.
Haildrifts, up to four feet deep of dime to nickel sized hail, occurred in low-lying areas near Zephyrhills, Florida on January 29, 1997.
Hailstones the size of softballs can fall at speeds faster than 100 mph

supercell

Supercells derive their rotation through tilting of horizontal vorticity (an invisible horizontal vortex) caused by wind shear. Strong updrafts lift the air turning about a horizontal axis and cause this air to turn about a vertical axis. This forms the deep rotating updraft, the mesocyclone.
A cap or capping inversion is usually required to form a downdraft of sufficient strength. The cap puts an inverted (warm-above-cold) layer above a normal (cold-above-warm) boundary layer, and by preventing warm surface air from sinking too far, allows one or both of the following:
Air below the cap warms and/or becomes more moist
Air above the cap cools
This creates a warmer, moister layer below a cooler layer, which is increasingly unstable (because warm air is less dense and tends to rise). When the cap weakens or moves, explosive development follows.
In North America, supercells usually show up on Doppler radar as starting at a point or hook shape on the southwestern side, fanning out to the northeast. The heaviest precipitation is usually on the southwest side, ending abruptly short of the rain-free updraft base or main updraft (not visible to radar). The rear flank downdraft, or RFD, carries precipitation counterclockwise around the north and northwest side of the updraft base, producing a "hook echo" that indicates the presence of a mesocyclone.
