.DISCUSSION...
Issued at 311 AM CDT Mon Aug 12 2024

...Synopsis...
500mb ridging slowly builds into the Northern Plains over the
next few days, keeping the weather quiet. As the ridge pushes
eastward by mid-week, the next batch of shortwaves will begin to
affect the FA Wednesday into Thursday. Thereafter, it appears
ridging will return, with no strong signal for precipitation
for the rest of the forecast period.

...This week...
The NBM and other ensembles are showing a pretty consistent
signal for at least normal temperatures during this 7 day
forecast period. If anything, as the 500mb ridging takes place
today into Tuesday, temperatures should be slightly above
normal. With the Wednesday/Thursday precipitation chances, more
clouds and any rain could keep temperatures from getting above
normal.

SPC has a marginal risk (level 1 of 5) for severe weather
Wednesday across far western Benson County. Do expect good
moisture return, with good 850mb southerly flow during the day
Wednesday, allowing precipitable water values to climb above 1.5
inches across most of the FA. Questions remain on the degree of
instability, with models showing quite a bit of remnant cloud
cover from nocturnal convection drifting through this FA. This
results in the best instability Wednesday developing over the
western Dakotas, closer to the main 700mb wave/surface low. At
this point, not seeing much of a low level jet forming Wednesday
night, so not seeing much of a reason for any stronger activity
that may develop over western North Dakota remaining strong as
it moves east into this FA. However, will continue to monitor
new data over the next few days.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 548 AM CDT Mon Aug 12 2024

There is some patchy fog around the FA early this morning, so
will have to see if any of it briefly moves into any of the TAF
sites. If it did, it would not last too long. Otherwise, winds
will remain light with only FEW-SCT cloud cover.

.FGF WATCHES/WARNINGS/ADVISORIES...
