.DISCUSSION...
Issued at 1200 AM CDT Sun Oct 18 2026
1034mb surface ridge sits just to the northeast of the area.
Dewpoints are in the upper 30s to low 40s with clear skies and
calm winds. We appear on track for a very strong radiational
cooling event through the next few hours which should lead to
the first widespread frost of the season.
Another strong upper ridge builds in over the central Plains
through the next few days and keeps our pattern blocked up
through the end of the week. We still look on track for dry and
pleasant conditions with seasonable highs in the 70s and lows in
the 40s. Guidance consensus is strong in keeping that pattern in
place at least into next weekend.
