Area forecast discussion, Aug 31, 3:30 AM CDT, 3 hours 13 minutes before
Area Forecast Discussion National Weather Service Aberdeen SD 330 AM CDT WED AUG 31 2016 .SHORT TERM...(Today through Friday) Issued at 325 AM CDT WED AUG 31 2016 Precipitation chances today, and fire weather on Thursday will be the forecast concerns. As of 8Z, a narrow line of convection has developed on the nose of a weak LLJ and mid level moisture advection. These storms should continue drifting southward through the morning hours and mainly impact locations between the James River and Highway 83. As the LLJ weakens later the morning, convection should dissipate as well. The rest of the short term portion of the forecast will be dry. On Thursday the region will be sandwiched between a high pressure to the east and a low pressure to the west. This region will see a fairly tight pressure gradient with strong southerly winds expected. With the winds and a dry airmass over the region, fire weather will be a concern along and west of the Missouri River on Thursday. Stronger winds are expected across most of the CWA on Friday with sustained winds of 30 mph possible. ESRL's Extreme Percentile indicates winds on Friday will range between the 90-95th percentile. While the winds will be strong, increasing LLM should limit fire weather concerns on Friday. .LONG TERM...(Saturday through Tuesday) Issued at 325 AM CDT WED AUG 31 2016 Southwest flow aloft with transient shortwave activity will dominate the extended as a broad upper trough shifts east from the Pac NW to the Rockies. Coupled with persistent sfc low pressure, this pattern will bring cooling temperatures and showers and thunderstorms through the extended period. Temperatures will fall well below average by Tuesday, with highs in the upper 60s to around 70. && .AVIATION...(For the 06Z TAFS through 06Z Wednesday Night) Issued at 1228 AM CDT WED AUG 31 2016 Expect VFR for all terminals with an east/southeast wind over the next 24 hours. && .ABR Watches/Warnings/Advisories...
