Area Forecast Discussion
National Weather Service Aberdeen SD
247 AM CDT Fri Mar 24 2017

.SHORT TERM...(Today through Sunday Afternoon)
Issued at 246 AM CDT Fri Mar 24 2017

Not much going on aside from the fog as precipitation associated
with an upper low remains to the south. Fog appears to be worst over
our favored areas in the northeast thanks to light northeast flow,
while the rest of the CWA is more hit and miss. 850mb dry air
advection should help with that today as an induced high pressure
bends around the north side of the low to the south. Continued
mention of fog into Saturday morning with an upslope component and
fair radiational conditions, though there will still be a gradient
across the forecast area.

Another upper wave in split flow moves across the intermountain west
late in the period, with energy ejecting out ahead of this feature
impacting mainly western counties before dissipating, similar in
progression compared to the current systems evolution on Thursday.
Thus, will maintain the model blend POPs with thermal profiles that
support all rain.

.LONG TERM...(Sunday Evening through Thursday)
Issued at 246 AM CDT Fri Mar 24 2017

The upper level pattern in the extended remains active. However,
most of the energy will stay to the south with the exception of some
shortwaves that will generate showers. The bulk of the next work
week looks dry, but best chances for precip will occur Tuesday
through Wed morning and then again on Friday. Upper heights remain
almost steady with no cold air intrusions to speak of, so expect
high temps in the 50s to lower 60s through the period.


.AVIATION...(For the 06Z TAFS through 06Z Friday Night)
Issued at 1229 AM CDT Fri Mar 24 2017

IFR/MVFR cigs will remain over the eastern half of the CWA overnight
and into the morning hours on Friday. VFR cigs are expected across
the west. Areas of fog are also possible across the east overnight
and Friday morning, possibly resulting in MVFR vsbys at times. By
midday or so, VFR conditions will prevail across the entire CWA.
