.SHORT TERM...
(Today)
Issued at 320 AM CDT Thu May 9 2024

Cold front is currently located from far NW AR through far SE OK
and westward across N TX. The boundary will continue a slow
advance eastward while becoming more stationary across N TX
through the day. Good agreement in guidance that storms will
initiate along or just north of the boundary by early afternoon
and spread E and NE through the evening. This convection will
likely spread into parts of SE OK with a risk of a few strong to
severe storms given forecast instability along the elevated
frontal zone. The more intense storms will focus south of the Red
River through the day. Further north across NE OK into far NW AR
an isolated high based shower is possible this afternoon, though
most locations will remain dry with cooler temperatures.

.LONG TERM...
(Tonight through Wednesday)
Issued at 320 AM CDT Thu May 9 2024

High pressure builds across the region Friday into Saturday with
dry weather and near normal temperatures. The pattern aloft will
feature a near stationary closed low over the southwestern CONUS
which is expected to finally move across the southern Plains
Sunday through Monday. Shower and thunderstorm chances will
increase accordingly with widespread rains appearing likely Sunday
night through Monday. Overall the severe weather potential appears
rather low at this time with limited instability and stronger flow
more south the region.

The flow aloft remains northwesterly through the central CONUS in
wake of the passing upper low and likely beyond as amplified
ridging develops over the western CONUS. This should allow several
stronger cold front to move through the region with the severe
weather potential remaining much less than has recently been seen.

(06Z TAFS)
Issued at 1221 AM CDT Thu May 9 2024

MVFR vsbys will be possible in patchy fog early in the
valid period, mainly at KFYV. TSRA that develops this
afternoon and evening is expected to remain south of
KMLC/KFSM, so will leave any mention out with this issuance.
Otherwise, VFR elements will prevail at all sites through the
period.
