As of this afternoon, still not much action, just a few isolated storms, but remember, this was expected.
For now, we just watch. Most likely, just as the sunsets (8:03pm), storms will begin to become more scattered to numerous. Also, these storms will have a higher than average chance of becoming severe. This is similar to what happened yesterday evening, as the sea breezes (Gulf and Atlantic) came together, just as the sunset, we saw an explosive development of storms right along US 301.
For now, just enjoy your day, an afternoon with hot and breezy conditions.
Tuesday AM update:
Weather Authority Alert Day (actually evening) issued Tuesday. Skies will started off beautiful with very warm conditions. Sunshine will give way to some clouds and gusty southwesterly winds to 20 mph. This mix of sun, warmth and wind will help destabilize the atmosphere, especially late in the day.
Weather Authority Alert will be from 4 p.m. to midnight.
Scattered evening storms will have a higher percentage than normal of turning severe, producing extensive lightning, wind gusts above 50 mph and 1-inch hail.
Not every backyard will see storms; they will be scattered.
_______________________________
Weather Authority Alert Day declared for Tuesday afternoon due to 50 percent chance of afternoon and evening storms that could disrupt your day.
The primary concerns with Tuesday afternoon's storms are hail up to 1 inch in diameter, strong gusty winds and lightning. The risk for tornadoes is low. The Storm Prediction Center has placed the Southeast under a Marginal risk for severe storms on Tuesday.
"Call it a WAAD Light," The Weather Authority's chief meteorologist John Gaughan said. "As a strong cold front heads towards Jacksonville tomorrow (Tuesday) some severe storms will be possible. As the front pushes through Wednesday, we will see only a few strong storms, more likely will be some downpours, finally near record cold Saturday morning, as temperatures Friday and Saturday morning's will be in the 40s just north and west of Jacksonville."
Tuesday morning will be quiet and mild, starting in the low 70s, with partly cloudy to partly sunny skies. Throughout the day the chance for rain grows, peaking at 50 percent in the afternoon and evening hours. The storms will erupt across Southeastern Georgia initially and later across Northeastern Florida. The precipitable water values are anticipated to be between 1.6 and 1.8 inch, indicating that some areas could see beneficial heavy rain Tuesday afternoon.
Average rainfall totals from tomorrow's storms should fall between one-half and 1.25 inch. We could see some isolated rainfall totals higher than that range, particularly for inland Southeastern Georgia. Rainfall this time of the year is especially valued in lowering our danger for forest fires.
Tuesday afternoons storms will be disruptive, but we have a chance for one or two of them to become severe. Wind gusts could be as high as 40-60 mph, which could down trees, cause damage to weak structure, and make crossing high bridges dangerous.
The Weather Authority will keep you updated ahead of the storms, you can look for hourly updates on the air, and live cut ins if any severe weather develops, we will also send out push alerts updating you on the storms and their positions throughout the day to the Weather Authority's app, which you can download in the app store, just search "WJXT." We will also update News4Jax.com, Facebook, and Twitter throughout the day. If you see strong storms or storm damage, please share your photos or videos with us on StormPins.
Around sunset, the storms will sweep offshore, leading to a more quiet night. The cold front behind Tuesday's storms will push through our area early Wednesday. That means Wednesday will begin cloudy with a few morning showers, but we will clear out and cool down for the end of the workweek.
