Weekly Weather Watch – 26 April, 2022 

Welcome to the last OU Nightly Weekly Weather Watch of the academic year!  

Norman, OK 

The weather this week will stay mostly calm until the latter half of the week and the weekend.

Throughout the week, high temperatures will climb from the lower 70s all the way up to the high 80s by Friday, April 29, 2022. 

However, on that Friday, there is a chance for severe thunderstorms, and those storms will drop the temperatures down into the mid-70s for the weekend. 

Friday, April 29, 2022, is not the only day with a chance for severe weather though.

The Storm Prediction Center (SPC) has issued a Marginal Risk of severe thunderstorms on Thursday, April 28, 2022. 

According to the SPC, “A severe thunderstorm or two may develop late Thursday afternoon or evening from northwest Texas into western Oklahoma and south-central Kansas.

If a storm can develop, large hail, strong gusts and a tornado will be possible.” 

The exact threats for Friday’s storms are not known yet because is it still three days away, but for all updates on the severe weather threats, check the National Weather Service Office in Norman, Oklahoma, website, Facebook page, or Twitter page

Fire Weather 

Since 66% of the continental United States, is dealing with some kind of drought, according to the U.S. Drought Monitor, conditions for fire weather are nearly always present. 

The SPC has issued a Critical Risk of fire weather conditions for Tuesday, April 26, 2022, and many NWS offices in the Plains have issued Red Flag Warnings because of the prime conditions for fire weather.  

The Red Flag Warnings extend from northwestern New Mexico, the Panhandles of Texas and Oklahoma, the eastern side of Colorado, most of western Kansas, and nearly all of Nebraska.  

These Red Flag Warnings are due to gusty winds up to 45 mph, relative humidity as low as 10%, and warm temperatures in the 60s and 70s.

These conditions can lead to rapidly spreading wildfires, so if an order to evacuate is issued, listen to your local emergency services and follow all safety precautions. 

Wednesday, April 27, 2022, also has a risk of fire weather with the SPC issuing an Elevated Risk for most of the Southwest and the southern parts of the Rocky Mountains. 

There is also a chance of elevated thunderstorms, which could produce lightning that could spark new wildfires. 

Severe Weather 

When it is springtime, it always seems like there are severe thunderstorms happening across the country.

The Mid-Atlantic is taking the hit Tuesday, April 26, 2022,, with the SPC issuing a Slight Risk for the eastern side of Virginia and a Marginal Risk for Virginia, North and South Carolina, and the eastern part of Georgia.  

This Slight Risk was issued mainly for the threat of severe wind gusts and large hail.

The SPC specifically warns of “sporadic damaging winds from locally strong gusts and small to marginally severe hail…across southern/eastern Virginia and parts of the Carolinas and eastern Georgia.” 

For Wednesday, April 27, 2022, the severe threats moves away from the Atlantic coastline and shifts to the Southern Plains.  

The SPC has issued a Marginal Risk of severe thunderstorms for the Panhandles of Texas and Oklahoma, the northeastern side of New Mexico, the southeastern corner of Colorado, and the western half of Kansas. 

According to the SPC, the storms that form will be “isolated strong to severe thunderstorms [that] may produce strong gusts and hail from eastern New Mexico and southeast Colorado into the Oklahoma and Texas Panhandles and western Kansas late Wednesday afternoon and evening.” 

The severe threat does not end on Wednesday, April 27, 2022, but rather it shifts southward.  

The SPC has issued another Slight Risk for most of the western side of Oklahoma, southern Kansas, and a small portion of northern Texas. 

According to the SPC, “a severe thunderstorm or two may develop late Thursday afternoon or evening from northwest Texas into western Oklahoma and south-central Kansas.

If a storm can develop, large hail, strong gusts and a tornado will be possible.” 

Winter Weather 

Even though it is nearly May, winter is still trying to hold on. Most of the Ohio Valley and surrounding areas are under a Frost Advisory and a Freeze Warning.  

This Freeze Warning extends from eastern Iowa, southern Wisconsin, northeastern Illinois, northern Indiana, southern Michigan, and western Ohio.  

Sub-freezing temperatures are expected overnight Tuesday, April 26, 2022, into the morning hours of Wednesday, April 27, 2022.  

According to the NWS Office in Northern Indiana, “frost and freeze conditions will kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing. Take steps now to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly.” 

The Frost Advisory covers parts of Iowa, Illinois, Indiana, Ohio, West Virginia, Kentucky, and Tennessee.  

Temperatures could dip down near freezing, causing frost to form on exposed surfaces, so be sure to protect sensitive vegetation. 

Have a fantastic summer and Boomer Sooner!
