.SHORT TERM...
(Today)
Issued at 351 AM CDT Mon May 20 2024

Showers and thunderstorms will be fading fast by daybreak and
should be gone entirely by mid morning. A dry day is then
expected, with very warm and humid conditions. Afternoon high
temperatures will generally range from the upper 80s to lower 90s
with breezy south winds.

.LONG TERM...
(Tonight through Sunday)
Issued at 351 AM CDT Mon May 20 2024

Shower and thunderstorm chances will begin to increase again late
Tuesday afternoon and especially Tuesday evening as mid level
temperatures cool and a cold front begins to move into the area
from the north. Some of these storms will likely be severe, with
all severe weather hazards possible.

The frontal boundary will stall by late Wednesday across the
southern part of our forecast area, and will be the focus for
another round of showers and storms on both sides of the front.
Severe storms will again be possible, with hail being the main
threat on the cool side of the front. Locally heavy rainfall will
also be possible with this round of storms.

The front will lift north as a warm front later Thursday, and
another round of showers and storms will erupt as an upper wave
traverses the area.

Shower and storm chances will continue Friday through the weekend,
but confidence in location and timing of the best storm potential
is low at this time range. Long range models suggest the stormy
weather pattern may finally break early next week, and this
pattern change may be the beginning of the annual trend away from
severe storms and towards summer heat that normally starts taking
place just after Memorial Day.

Lowered NBM high temperatures late this week through the weekend
towards the MOS guidance numbers as the NBM seems to be
kickstarting the summer heat a bit too quickly.

(06Z TAFS)
Issued at 1220 AM CDT Mon May 20 2024

Decaying cluster of thunderstorms will continue over northeast
OK, with some re-generation of cells possible early in the
forecast period. Still could see strong gusty winds at
KBVO/KTUL/KRVS associated with any storm. Most likely, any storms
should dissipate before reaching northwest AR. Aside form that,
VFR conditions will prevail with gusty south winds from mid-
morning until around sunset Monday.
