National Weather Service

Much of northeast Oklahoma was under an excessive heat warning until 8 p.m. Monday, and it’s just the start of a week of potentially dangerous heat.

The National Weather Service said additional heat advisories and warnings are likely as summer heat and humidity linger over the area.

Heat index values will be above 100 in many areas Tuesday to Thursday, with some locations across eastern Oklahoma and west central Arkansas reaching 112 degrees.

Yes, the climate is warming, and yes, we human beings are causing this warming. And yes, things look very bad. But what can be done...and what can **we** do...right now? Our guest has some answers; she is Dr. Kimberly Nicholas, Associate Professor of Sustainability Science at the well-regarded Lund University in Sweden.

Okmulgee County Emergency Management

Emergency management officials are urging Okmulgee County residents and business owners to report any damage to their property from heavy rains and flooding Sunday and Monday.

Damage can be reported at It will help the county's request for federal disaster assistance.

Some areas of the county may have received 1 foot of rain Sunday night, and flooding shut down Highway 75 early Monday morning.

National Weather Service

The National Weather Service has issued a tornado watch for eastern Oklahoma through 7 p.m. Thursday.

The tornado watch covers nearly two dozen counties, including the Tulsa metro area.

NWS Tulsa forecasts supercell potential from roughly 3 p.m. to 8 p.m., with hazards including hail up to baseball size, wind gusts up to 65 mph and a few tornadoes.

Additional thunderstorms are possible for eastern Oklahoma overnight, with large hail, damaging winds, heavy rain and flooding possible. There will be a decreased but continued low tornado threat.

National Weather Service

The National Weather Service in Tulsa says severe storms are possible across northeast Oklahoma from late Monday afternoon until early Tuesday morning.

Baseball- to softball-size hail, damaging winds up to 70 mph, and tornadoes are all possible, with chances for those hazards increasing as storms move south and east.

According to a NWS briefing, locations along and northwest of I-44 will likely remain behind a cold front over the region, limiting severe weather potential there. 

Multiple rounds of showers and thunderstorms will slowly move across northeastern Oklahoma through Thursday.

Rainfall totals of 2 to 4 inches are likely, with up to 6 inches in some spots possible, according to the National Weather Service. A flood watch is in effect Tuesday night through Thursday morning. Creeks and flood-prone urban areas are most likely to be affected.

The threat of severe weather is low. Some severe storms bringing hail and 60 mph wind gusts are possible Tuesday night.

The higher severe weather risk is in southwest and central Oklahoma.

National Weather Service

Be prepared for severe weather across Green Country overnight Friday.

The National Weather Service expects a line of storms to roll through overnight starting around 8 p.m. The greatest threat for severe storms will be in a bowing line mainly south of I-40, but at least a few severe thunderstorms are expected along the I-44 corridor.

Hazards for the Tulsa area include damaging wind gusts up to 60 mph, large hail up to half-dollar size and heavy rainfall that could cause flash flooding.

South of I-40, there's potential for isolated tornadoes along the line of storms.

National Weather Service Tulsa

This afternoon’s isolated thunderstorms will ramp up through the evening, meaning a threat of severe weather across northeastern Oklahoma.

The National Weather Service in Tulsa expects several strong to severe storms as a cold front pushes a line of storms across Green Country.

Severe potentials are expected to exit by late evening. Large hail up to 2 inches and greater, damaging wind gusts of 60 to 70 mph, and also a tornado threat will be possible across eastern Oklahoma and northwest Arkansas.

It’s nearly spring, and you know what that means: potential severe weather for Green Country.

The National Weather Service in Tulsa says there's an elevated severe weather risk for the area Tuesday night into Wednesday, mainly southwest of State Highway 351 and, farther east, south of I-40.

Potential hazards include winds up to 60 mph, hail as large as golf balls and a low risk of a tornado. The highest chances for a tornado are in southeast Oklahoma.

Local flooding is also possible if heavy rainfall lingers over an area.


OKLAHOMA CITY (AP) — President Donald Trump officially declared a federal disaster on Monday for 13 Oklahoma counties battered by a late October ice storm.

The declaration means federal funding will now be available to state, tribal and local governments and some private nonprofits for storm-related costs, the White House said in a press release.

It may be fall, but Oklahoma is seeing winter weather.

The National Weather Service forecasts significant icing in northeast Oklahoma into Tuesday evening, with up to a total of 0.4 inches possible across western Osage and Pawnee counties.

Ice accumulation on trees that are still bearing leaves and wind gusts around 30 mph make tree damage and power outages "very likely."

Significant travel impacts are expected, and bridges and overpasses are the biggest concern. 

The earth's climate has warmed significantly since the late 19th century, and the activities of humankind -- primarily greenhouse-gas emissions -- are the main cause behind this warming. Such is the consensus view of the world's climate scientists. On today's ST, we explore the issue of climate change with a noted **political** scientist. Joshua Busby is an Associate Professor of Public Affairs and a Distinguished Scholar at the Strauss Center for International Security and Law at the University of Texas.

Our guest is the California-based seismologist, Dr. Lucy Jones, whose new book is "The Big Ones." It offers a bracing look at some of the history's greatest natural disasters, world-altering events whose reverberations we continue to feel today. At Pompeii, for example, Dr. Jones explores how a volcanic eruption in the first century AD challenged prevailing views of religion. Later in the book, she examines the California floods of 1862 and how they show that memory itself can change or fade over successive generations.

National Weather Service-Tulsa

The National Weather Service in Tulsa is advising of a 50% chance of thunderstorms in the afternoon heat. Any thunderstorm that does develop will have a chance to become severe.

There is also a risked of more sudden microburst down drafts. Those are caused when a thunderstorm collapses and winds gust out. When those winds hit the ground, they spread out and can cause wide spread damage.

TULSA, Okla. (AP) — Oklahoma — and not Texas as first thought — had the hottest summer in U.S. history last year, inching out the Lone Star state by two-tenths of a degree.

In the final tally, national climatologists say Oklahoma's summer averaged 86.9 degrees and Texas came in at 86.7 degrees.

Deke Arndt of the National Climatic Data Center says Oklahoma surpassed its own heat record of 85.2 degrees set in 1934.

Jan.-April Okla. temperatures warmest on record

OKLAHOMA CITY (AP) — The Oklahoma Climatological Survey reports that the average daily temperature from January through April is the warmest on record in the state.

The four month stretch includes the warmest March ever recorded in Oklahoma in records that date to 1895.
