...A Few Severe Thunderstorms Expected...
This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.
.DAY ONE...Today and Tonight.
SEVERE THUNDERSTORM.
RISK...Elevated.
AREA...Eastern Oklahoma and Northwest Arkansas.
ONSET...Now... ending from northwest to southeast
later tonight.
DISCUSSION...
Thunderstorms will continue to develop across the middle of
eastern Oklahoma into west-central Arkansas. A few of these
storms will be severe through the evening hours with hail
up to 2 inches and wind gusts near 70 mph associated with
the strongest storms. These storm will shift east
into the body of Arkansas this evening. However, additional
storms will develop this evening from northwest Arkansas into
northern Oklahoma. These storms will merge into a complex
and travel southeast across the region during the night.
After Midnight the threat will be for quarter size hail
and some wind gusts of 55 to 65 mph. The storm complex will
start to exit southeast Oklahoma toward morning.
Locally heavy rain will occur in some locations. Amounts
near 3 inches will occur near where strongest storms occur,
and / or where multiple storm cross the same areas. Many
locations will see 1/2 to 1 inch of rain.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Likely.
.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Thunderstorm Potential...Heavy Rain Potential.
MONDAY...No Hazards.
TUESDAY AND WEDNESDAY...Very High Fire Weather Potential.
THURSDAY AND FRIDAY...No Hazards.
EXTENDED DISCUSSION...
The remaining rain and thunderstorms will push out of
southeast Oklahoma tomorrow morning.
A colder and dry airmass will settle into the region
for the first half of next week. Warmer conditions are
expected the later half of the week. A freeze will have
occurred in most parts of eastern Oklahoma and northwest
Arkansas by Wednesday. This will encourage grasses to
become dormant and be more receptive to drying when
the warmer weather returns next Thursday and Friday.
