One more dry day

Main threats

No widespread hazardous weather is expected, though isolated strong (briefly severe?) storms are possible from Wednesday through Monday. Gusty winds, small hail, and heavy rainfall could accompany any stronger storms. As always, be mindful of that lightning.

Summary

Today is our last dry day for a while, folks, so be sure and get out and enjoy it if you can. A return to a more unsettled pattern awaits us tomorrow and will be with us for some time.

It had looked like rain would hold off until mainly the afternoon hours of Wednesday and Thursday. Now, it looks like it could be anytime during the day. In fact, we could see showers and storms around as early as daybreak tomorrow. Just keep the rain gear handy. Coverage is set at about 50%, so half of us may not see anything.

Another 50/50 shot at rain and storms comes Thursday, followed by much greater chances of rain for Friday, Saturday and Sunday. All of us will have seen some rain by Sunday evening. Rainfall totals will vary from around an inch to as much as 3 inches. It just depends on how many of the storms you end up underneath.

This pattern looks to break by one week from today, with a return to drier weather.

WeatherTAP WeatherFACT

Wind is always the result of a pressure imbalance. Always. The pressure imbalance is quite severe in tornadoes, with the funnel having remarkable low pressure compared to the surrounding air mass. That’s why the winds are so strong in a tornado.

For those of you heading to the beach, the seabreeze that develops each evening is due to the beach warming up faster than the water in the daytime sun. The warm air on the hot beach rises, creating low pressure (rising air). The cooler ocean water cools the air above it and leads to sinking air (high pressure). High pressure always flows toward low pressure, creating a breeze that blows from the cooler ocean to the warmer land.

Records

Long Island, New York was hit by a hurricane on this date in 1825. The early-season storm originated around Cuba and tracked up the East Coast, creating a path of coastal destruction from Charleston, South Carolina to New York City. The newspapers reported that “many were lost at sea.”

On this day in 1860 a tornado struck Iowa that some historians argue is unmatched by any twister since. The tornado, referred to as the Commanche Tornado, was said to have had winds in excess of 300 mph to have damaged the landscape the way it did.

Even in these sparsely populated times, the tornado killed 141 Iowans and injured another 350. Folks who later died from injuries may have taken that death toll closer to 200. The twister was on the ground for up to 6 hours!

News

A gentleman (@GrantWTSP) on Twitter posted this pic this morning of the sunrise in Florida. He captioned the photos, “Great sunrise pic this morning from @CAPTTCANADA! The high thin clouds in this photo could barely be seen by the satellite, but boy did they make a beautiful sunrise!”  Beautiful, indeed!

I will also mention that the area of low pressure in the southwest Gulf of Mexico continues to be monitored, though its chances of development have lowered from 60% to 40% now. Still, moisture from that system will likely influence our weather this weekend.

You all have a great day!
