.DISCUSSION...
Issued at 130 PM CDT Mon Oct 6 2025
There are still a few residual sprinkles/light showers west of the
James Valley this afternoon, associated with shortwave energy in the
upper trough. Some of this isolated activity on radar may be no more
than virga as sfc high pressure has settled over SD. Mid levels dry
out more by 21z cutting off the shower moisture.
The upper trough and sfc high are keeping temperatures seasonable.
Confidence is low in overnight lows, though, as NBM has a high bias.
As the sfc high slides farther southeast tonight, westerly winds may
be just high enough to prevent strong radiational cooling. It looks
like high clouds will persist into the evening, as well, sliding
south with the shortwave. Can`t rule out some patchy frost in north
central SD, but even 25th percentile guidance isn`t leaning that
low. Lowered temps a couple of degrees below guidance for now.
Drier mid level air moves in Tuesday night, but so does some waa as
an upper ridge begins to transition into the Plains. Southerly winds
increase ahead of a Rocky Mountains low on Wednesday. The low/trough
moves into the Dakotas on Thursday as a dry front. Temperatures
climb above normal again starting on Wednesday and continuing
through the weekend. Next chance for any showers appears to hold off
until Sunday, though there are some timing differences in the
models.
