More solid area of rain showers is moving north-northwest into
the RRV as expected. So the high pops continue. Other showers
with pockets of heavier rain into the Devils Lake basin and in
north central MN. So idea of highest chc of rain this morning is
indeed working out.

...Synopsis...
Forecast is progressing as anticipated early this morning. Upper
low is in northwest SD with a 500 mb vort in western Missouri.
Feed of deeper moisture extends from eastern Missouri northwest
across Iowa into Minnesota and there is a 40 kt 700 mb jet
involved as well. This feed of deeper moisture and mid level jet
will aid in an increase in shower coverage thru the morning
before diminishing this aftn. This is what was shown 24 hours
ago with an increase in coverage of showers arriving late Thu
night and lasting thru early Friday afternoon. Thus will
maintain the categorical pops for most areas thru 18z then went
close to model blend pops which shows chances of rain
diminishing mid to late afternoon into this evening. Additional
rain amounts 12z Fri to 12z Sat look to be in the 0.25 to 0.75
inch range. Isolated thunderstorms possible as well, but with
main upper low forecast to drop more southeast thru today and
tonight feel conditions less favorable for any funnels. Sfc low
however is present in east central SD near Huron and this will
be near the ND/SD/MN border by late today.
500 mb low and trough remains over Minnesota and eastern ND
Saturday but mositure feed is much less into the system. But
enough for continued scattered showers. Sunday will see upper
wave shift a bit more east with showers limited to east of the
Red River in MN then Monday will see clearing progress east thru
the entire area.
A much needed prolongued dry period is in store from Monday thru
Saturday across the area, as next in our series of upper lows
this time develops over the central or southern Plains with flat
upper ridge, 500 mb high heights, building north of upper low
across the area and south central Canada.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 643 AM CDT Fri Sep 19 2025
Variable conditions today, though for most areas it should be
IFR/low end MVFR in terms of vsby and cloud bases. Exceptions
have remained in the immediate Red River valley where cloud
bases have been higher. I would think there is a good chance of
them lowering this morning. Mainly ENE wind 10 kts or less thru
tonight.
