.DISCUSSION...
Issued at 303 PM CDT Mon Jun 1 2026

Through Tuesday: Latest satellite imagery/RAP analysis showed a mid
level ridge axis to our west that was resulting in a northwest flow
across the CWA. This northwest flow was supporting an MCS moving
south across northern Alabama. The western portions of this MCS was
spreading into our northeast most zones. Severe storms capable of
damaging wind gusts and some hail will be possible with this
activity this afternoon. Elsewhere across the CWA microburst pulse
severe storms are possible as local microburst checklist showed
microbursts will be likely this afternoon considering the
anticipated atmospheric parameters. In addition latest guidance
still showed additional development across the northern portions of
our CWA this evening along the boundary leftover by the current MCS.
The main threat for severe through this evening will remain damaging
wind gusts although hail and locally heavy downpours.  A Severe
Thunderstorm Watch has been issued for our northeast this afternoon
but an additional Watch or an expansion of the current Watch is
possible this evening due to the potential of more organized
convection dropping through our CWA. In addition, with the heat and
humidity across the CWA away from convection, peak heat index values
will be around 105F in may areas this afternoon. This area is
outside of our northeast due to the ongoing convection.

It's possible the convection tonight will last past midnight across
the southern portions of our CWA. Tuesday a >1028mb high will drop
out of Canada and become centered over the Great Lakes region. This
will bring cooler and drier air into the northern portions of our
CWA. This will result in the highest heat indices and greatest rain
chances across our southern zones Tuesday afternoon. /22/

Tuesday Night through Sunday:

Once the trough shifts south, the frontal boundary will push through
the region Tuesday afternoon. Drier air will provide relief from the
heat over the last few days as high/low temps feel closer to early
June (near seasonal average). High pressure will settle over the
Great Lakes, traversing southward over the week and provide a
ridging pattern for our region. Heading into the weekend, the high
will shift towards the east, winds will shift to the
south/southeast, increasing humidity across the area. With
increasing humidity, 40-75% rain chances return over the weekend
with the greatest chances in the south/southwestern portion of the
ArkLaMiss region. /SW/
