Baldwin’s Saturday Wx Blog for Aug 29

At a Glance

48-Hour Weather

Threats

The Storm Prediction Center has placed our area in the marginal risk for severe storms for this afternoon and evening. A frontal boundary will drop in from the north, sparking some storms. Some of those storms could contain gusty winds, cloud-to-ground lightning, and heavy downpours of rain.

More showers and storm are likely Monday, with some of those storms possibly being on the strong side, as well.

Baldwin’s Hay Day Forecast

Today and Monday look to be the wettest days of the period. At this time, the middle to end of next week is looking drier.

Almanac

Yesterday’s National High and Low Temperature

High: 118 at Topock, Arizona

Low: 30 at Copper Basin, Idaho

Tropics

I’m still monitoring two areas of concern out in the Atlantic. These will be something to watch in the coming week. Even the closest system, should it affect the US, is still about a week away. The next named storm will be Nana, followed by Omar.

Today’s Wx Hazards Across the Nation

Severe storms threaten portions of the East Coast and New England, while more severe storms and heavy rainfall threaten much of Arkansas. That area saw heavy rain from “Laura”, as well. Flash flooding from thunderstorms threatens parts of Arizona, while the wildfire danger increases across the Northwest, where hot and dry conditions are leading to increasing wildfire dangers.

Tomorrow’s Wx Hazards Across the Nation

Heavy downpours threaten parts of the Midsouth, northern plains, and Southwest. Severe storms threaten portions of the central plains. FYI, that heavy rain threat moves east across TN during the night and early portions of Monday.

Monday’s Wx Hazards Across the Nation

More unsettled weather prevails, with flooding downpours across Pennesylvania and Maryland and parts of the southern plains. A severe storm risk will be found stretching from the southern plains to the Lower Mississippi River Valley. Notice that mixed wintry precip across Idaho and Wyoming! The seasons are beginning to change! That’s the first wintry precip to show up on the maps for this changing season.

Records

On this day in 1986 Crossville recorded daily record low of 44 degrees. Brrrrr. That’s chilly for this time of year! Clarksville, TN, 50 miles northwest of Nashville, also dropped to 44 degrees, setting an all-time low for the month of August for them.

On this day in 200 Hurricane Katrina made landfall in Plaquemines Parish in southeastern Louisiana with maximum sustained winds near 125 mph, a strong category-three hurricane. This was the third most-intense land-falling hurricane in U.S. history. The center of the hurricane passed just east of New Orleans, where winds gusted over 100 mph. Widespread devastation and unprecedented flooding occurred, submerging at least 80 percent of the city as levees failed. Farther east, powerful winds and a devastating storm surge of 20-30 feet raked the Mississippi coastline, including Gulfport and Biloxi, where Gulf of Mexico floodwaters spread several miles inland. Rainfall amounts of 8-10 inches were common along and to the east of the storm’s path. Katrina weakened to a tropical storm as it tracked northward through Mississippi and gradually lost its identity as it moved into the Tennessee Valley on the 30th.

Long Range Outlook 

Cooler and wetter conditions still look to prevail for the first days of September.

Weather Shot

Oftentimes, birds will get trapped in the calm weather of the eye of a hurricane. They simply can’t escape into the severe weather surrounding the eye. This means some birds will travel hundreds of miles in that eye to stay safe. That’s what happened with Laura, as this radar image shows! How wild is that!?

NASA Nerdology

A flat tire can take drivers by surprise. That should be happening less these days, thanks to tiny sensors that light up a dashboard warning whenever the tire pressure is off.

Proper tire pressure was crucial for a safe space shuttle landing on Earth, but in the early days of the program, there wasn’t a good way to gauge pressure in flight accurately. Among other solutions NASA explored, the agency contracted with a company to build a tire pressure sensor for the space shuttle.

The technology converts pressure into electrical resistance and generates real-time readings. After the company delivered the device to NASA, they adapted the sensor for cars. Today, U.S. law requires a pressure gauge on every car tire.

You all have a great day!
