Severe thunderstorms moved across the state Tuesday afternoon and evening, downing electrical lines, damaging some homes and businesses, and dropping large hail. No injuries have been reported.
Updated April 27, 9:07 a.m.:
Authorities are getting a better idea Wednesday morning of how much damage resulted from the severe storms. Several thousand Oklahoma Gas and Electric and Public Service Company of Oklahoma customers were still without power early Wednesday.
Only a handful of small tornadoes affected mostly sparsely populated areas. Oklahoma City Emergency Manager Frank Barnes says the city is conducting preliminary damage assessments totaling about 51 square miles in four areas:
- Mustang Road to County Line Road between SW 59th and 15th Streets
- Wilshire Blvd. to NW 122nd Street between Meridian and Council roads
- Air Depot Blvd. to Westminster Road between Britton Road and NE 150th Street
- Westminster Road to Indian Meridian roads north of NE 122nd Street
Pontotoc County Emergency Manager Chad Letellier said he received reports a car port was destroyed, along with damage to a mobile home. The First Methodist Church in Davis received significant damage, along with other businesses.

There’s still a risk of tornadoes, but as of right now it appears the threat of long-track, damaging twisters is diminishing. Straight-line wind damage and brief spin-ups are more likely, according to National Weather Service meteorologist in charge David Andra. Hail sizes will also continue to decrease.
The Tornado Watch issued this afternoon for much of the state has been canceled for Jackson County in far southwest Oklahoma, and several other counties in Texas.
Updated 6:35 p.m.:
Several severe thunderstorms producing golf ball-sized hail and rotating wall clouds have moved across western Oklahoma Tuesday afternoon and evening. One Tornado Warning was issued at 5 p.m. in far southwest Oklahoma in Tillman County near the town of Tipton, but so far there have been no reports of any injuries or damage. A Flash Flood Warning was also issued for that same storm.
Meteorologists at the Norman Forecast Office say supercell thunderstorms are likely to move across the state over the next several hours, but low-level wind shear - one of the main ingredients of tornadoes - hasn't developed yet.
6pm update pt3 - This is the time of evening when low level wind shear typically increases. We'll be watching trends to see if this happens
— NWS Norman (@NWSNorman) April 26, 2016
6pm update pt4 - computer models suggest we might see low level wind shear increase so everyone should remain alert next few hours.

"It's possible we could see the storm areas in the west merge and move into the [Interstate] 35 corridor as a line," meteorologist-in-charge David Andra said. "If that occurs it would be a mitigating factor for significant tornadoes."
Updated 2:41 p.m.:
The Storm Prediction Center has issued a Tornado Watch for much of the western half of the state, effective until midnight. It's been classified as a "Particularly Dangerous Situation," a rare designation the Weather Service reserves for special cases.
According to the watch, there's a high probability of tornadoes, including strong twisters rated between EF2 and EF5.
Intense tornadoes, 4-inch diameter hail and strong winds are possible. Tornado watch is in effect until midnight. @kgounews

820am - Moderate risk is mainly driven by potential for very large hail. Tornado potential is still there, too. Still complicated forecast
— Rick Smith (@ounwcm) April 26, 2016
Norman Forecast Office Warning Coordination Meteorologist Rick Smith says storms could begin forming around 3 p.m. just east of a dryline – the boundary where storms form.
"We expect that dryline to be sitting somewhere along Highway 81,” Smith said. “Basically from Enid to El Reno, Chickasha, Duncan, Waurika, sometime between 2 and 3 o'clock this afternoon."
East of that location, there's a significant risk of severe weather, but further west, the threat is very low. The dew point temperature – the point where the air is saturated – will be much lower behind the dryline across far western Oklahoma.
Meteorologists say the wind shear isn't favorable for an outbreak of long-track tornadoes across a wide area, but Smith says strong twisters can't be ruled out.
"If we get severe storms to form, somebody's going to get some significant severe weather today,” Smith said. “And all we can really do at this point is pay attention, be aware, and know that that could happen."
Baseball-sized hail is large enough to cause damage to homes and vehicles, and could significantly affect travel between 4 and 7 p.m.
"We still think the Oklahoma City metro area and the I-35 corridor - a county or two on either side - we think those storms will primarily be after 4:00 o'clock today,” Smith said.

The risk of tornadoes will likely increase substantially after 6 p.m. Ada and Durant could see severe storms as late as midnight.
"The tornado risk does maintain itself through the evening into eastern Oklahoma,” NWS Senior Forecaster Wayne Ruff said. “It is, however, maybe slightly less as you get toward Arkansas."
