NWS Forecaster Discussion
984 fxus63 kabr 082049 afdabr Area forecast discussion National Weather Service Aberdeen South Dakota 349 PM CDT Friday Aug 8 2008 Short term...tonight through Sunday night Currently the upper level longwave pattern shows meridional flow with upper level ridging over much of the central to western US and a longwave trough over the eastern US. At the surface a high is parked over the Mississippi River valley...putting US on the unstable side of it. A very slow moving warm frontal boundary is situated over central to northern South Dakota. Additionally...an upper level shortwave trough is riding up over the ridge and is located in western North Dakota. The forecast challenges in the short term include precipitation chances with the passage of this and other minor shortwave troughs through the longwave pattern. Both the GFS and the NAM are in good agreement that our northeastern County Warning Area corner should see some precipitation as the shortwave clips on through this afternoon into the evening. Kept probability of precipitation in for eastern County Warning Area as these ridge runner troughs have the tendency sometimes to take a more southward dive than anticipated. However...significantly reduced probability of precipitation overnight as trough should be well into Minnesota by midnight. Both 12z and 18z NAM pick up on a surface convergence zone late Saturday afternoon into the evening and another upper level shortwave trough passing through the flow pattern. Slight chance to chance probability of precipitation in the grids reflect anticipated precipitation. 12z GFS not picking up on this...but NAM has been more consistent run to run. Finally...timing precipitation again Sunday night into Monday with the approach of the next surface low poses the final challenge in the short term. GFS and NAM both handle the overall surface trough fairly consistently with GFS more aggressive on closing the surface low. Long term...12z Monday through Friday biggest challenge facing the long term deals with precipitation chances through the period along with model selection. The long range models agree for the most part in the early part of the extended. Closed upper low in western Canada drops down to the internation border. At the surface...ec/GFS/dgex agree on a closed surface feature scooting east along the ND/South Dakota border Monday into Tuesday. The GFS shows an increase in 7h and 850 mb frontogenesis along with increasing 7h Theta-E forcing. Models are advertising an increasing amount of precipitable waters ahead of the surface feature...with GFS showing an area of 1.50 plus inches 00z Tuesday through 12z Tuesday. Have pretty much left inherited weather grids intact for the 12z Monday through 00z Wednesday time period. Did break the grids up into 6 hourly pieces to better time the surface trough/low passage. Models then begin to diverge greatly in the solutions heading into the weekend. The GFS continues to drop the aforementioned 500 mb closed low into the northern Continental U.S....although the 12z solution has backed off a bit on southern extent versus the 06z solution. The 12z ec on the other hand has dropped the 500 mb closed low into northwest Minnesota by 12z Friday...reaching NE South Dakota by 00z Saturday. Run to run consistency for any model right now seems to be a bit lagging...so am just going to leave inherited dry weather grids as is until things shake out a bit more. Temperature wise...inherited temperature grids also seemed reasonable. If the upper low does indeed drop further south into region heading into next weekend...then temperatures may need to be dropped a bit as 850 mb temperatures approach +10 with the ec showing 7h temperatures around +2 by 00z Saturday. && Aviation... extreme northeast South Dakota and western Minnesota could see short periods of MVFR/IFR associated with an area of showers and thunderstorms late this afternoon into this evening. Otherwise expect good VFR conditions for visibilities and ceilings throughout the period. && Abr watches/warnings/advisories... South Dakota...none. Minnesota...none. && $$ Short term...gionta long term...Hintz aviation...gionta Weather.Gov/Aberdeen
