.DISCUSSION...
Issued at 1145 PM CDT Fri Apr 17 2026

Surface observations and radar imagery indicated that the highly
anticipated cold front extends from southwest Oklahoma, through
central Oklahoma and into far southwest Missouri. Short range
model guidance continues to indicate that the showers and
thunderstorms will reach McCurtain County in southeast Oklahoma by
around 07-08z. We will then see rain chances traverse through the
region from northwest to southeast today. Some of these storms,
especially the ones that initially move into our northwest zones,
could be strong to severe at times, something we will need to
watch this morning and into the afternoon. While we are not
currently outlooked from the Storm Prediction Center, there
remains the potential that some storms could be strong and even
severe throughout the day.

Most areas will see their high temperatures for the day this
morning, as temperatures will begin to drop through the day behind
the passing cold front. So while high temperatures for today might
say the mid 70s or lower 80s for some, these will not be the
temperatures we feel during the afternoon hours. Tonight will be
quite chilly for this time of the year, with lows ranging from
around 40-50 degrees across the region, cooler to the north and
warmer to the south. For Sunday and Monday, temperatures will be
in the 70s, with similar lows in the 40s and 50s each night.
Tuesday will still be pleasant for most, but we will start to see
the 80s return to the area, especially for our eastern zones. We
will see the 80s creep back into the entire region slowly before
they become more widespread by Thursday. While there will be some
diurnally driven convection possible from Tuesday through Friday
of next week, right now it doesn't appear to be widespread or very
significant. /33/
