Good Evening, This is Jonathan with the National
Weather Service in Norman Oklahoma, and this is a Severe weather briefing for the upcoming
weekend. Headlines
This briefing will cover our regions severe weather chances for Saturday through Monday.
Chances, coverage, and timing of storms Saturday will revolve heavily around the strength of
the cap. This could limit development across a good part of the region.
As for Sunday and Monday, the dry line will surge eastward off the panhandles increasing
the chances across the region of Large Hail, Damaging Winds, and Tornadoes. National Weather Service Norman, OK
Here is the Day 3 Outlook from the Storm Prediction Center. Valid for Saturday, this places
much of the central and western Oklahoma and western north Texas in a See Text Region.
This means that general thunderstorms are currently expected with limited chances for
organized severe storms. National Weather Service Norman, OK
Now lets take a look at the extended outlook from the Storm Prediction Center. At the moment,
they have both Sunday, Day 4, and Monday, Day 5, highlighted for a chance of organized
severe storms. National Weather Service Norman, OK
Going into a little more detail, thunderstorm chances will increase Late Saturday afternoon
and evening as the dry line stalls across the Texas Panhandle near the Oklahoma/Texas
Border. Any storms that are able to overcome the cap will have the potential for damaging
winds and large hail. On the whole, storms will be
widely scattered in nature. National Weather Service Norman, OK
Severe weather chances increase on Sunday as the dry line surges eastward through the
afternoon and evening hours. With a weaker cap and more favorable environment, severe
storms will be possible, with large hail, damaging winds, and tornadoes possible. Tornadoes
will be more likely near the intersection of the dry line
and cold front, which offers the greatest
dynamics and storm scale environment. National Weather Service Norman, OK
Severe weather chances will return on Monday as the dry line once again surges eastward.
Once again, severe storms will be most likely near the intersection of the dry line and
cold front/stationary front across north central Oklahoma. Headlines
In summary, confidence continues to grow for significant severe weather this weekend. Questions
remain for the coverage and intensity of storms on Saturday, while conditions look greatest
for Sunday-Monday with the Dry Line push. Large Distructive Hail, Damaging Winds, and
Tornadoes all pose a significant risk to the region. www.weather.gov/norman
