Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
1054 AM CDT Fri Mar 24 2017

Issued at 1053 AM CDT Fri Mar 24 2017

No major changes anticipated this morning as the forecast looks on


.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 12Z TAFS through 12Z Saturday Morning)
Issued at 622 AM CDT Fri Mar 24 2017

IFR cigs across the east and more widespread mvfr vsby will
improve by afternoon. KATY may see fog redevelop Saturday morning.
