Area Forecast Discussion...UPDATED
National Weather Service Aberdeen SD
627 AM CDT Wed Jul 17 2019

.SHORT TERM...(Today through Thursday Afternoon)
Issued at 436 AM CDT Wed Jul 17 2019

Several shortwaves continue to generate convection across the region
this morning. The best forcing this morning is associated with a sfc
low nosing into south central SD. As this low pushes farther north
and east today, thunderstorms will regenerate across eastern SD and
west central MN. LLM is abundant ahead of the low. Coupled with a
jet streak, there will be ample instability even with convective
debris left over from the morning activity.

Weaker shortwave energy will be present along the SD/ND border
Thursday morning that may kick off some additional showers and
thunderstorms in far northern SD. Another sfc low in southwest SD
will help pump warmer air back into the region on Thursday. Highs
will soar back into the 90s across central SD.

.LONG TERM...(Thursday Evening through Tuesday)
Issued at 436 AM CDT Wed Jul 17 2019

Friday will be the quietest day this week. Showers and thunderstorms
move back in Friday night and Saturday as a sfc low moves into the
central Plains. Canadian high pressure will build in for the
remainder of the weekend and early next week bringing cooler
temperatures and drier conditions. By mid week, a highly amplified
ridge over the intermountain west will start to push heights higher
and temps will be on the rise again.


.AVIATION...(For the 12Z TAFS through 12Z Thursday Morning)
Issued at 626 AM CDT Wed Jul 17 2019

VFR conditions will prevail through the period except in the
vicinity of thunderstorms. Thunderstorms are expected to redevelop
late this afternoon near KATY.
