NWS Forecaster Discussion




Area forecast discussion for western South Dakota and northeastern Wyoming 
National Weather Service Rapid City South Dakota 
1122 PM MDT Thursday Mar 26 2015 


Short term...this evening through Friday night 
issued at 235 PM MDT Thursday Mar 26 2015 


20z surface analysis had nearly stationary frontal boundary from 
central Montana into central NE. Leftover showers mainly confined to the 
terrain of the Black Hills and downstream convergence area near the 
Pine Ridge. This is in wake of shortwave trough shifting southeast 
into the Midwest. Additional shortwave energy noted over central 
BC/sk...which will swiftly move into the northern plains tonight 
bringing another period of -shrasn to the County Warning Area overnight into Friday 
morning. Best chances will be over the northern Black Hills where 
some upslope enhancement possible between 06z-15z Friday and then 
over northwest South Dakota where best forcing occur along frontal boundary. 
Temperatures will be near guidance tonight. 


Friday...leftover morning showers will end as the front shifts east 
as a warm front with much warmer temperatures expected. Gusty 
northwest winds expected at times by afternoon as boundary layer 
mixes out. Temperatures will be near guidance...except perhaps 
slightly lower in the far east nearest precipitation that fell 
today. Quiet weather expected Friday night. 


Long term...Saturday through Thursday 
issued at 235 PM MDT Thursday Mar 26 2015 


A very warm start to the weekend as a shortwave ridge passes over 
the northern plains. Highs on Saturday will be in the 70s to 
around 80 degrees across the plains. There is potential for fire 
weather issues across parts of northeast Wyoming into southwest South Dakota if 
winds increase enough in the afternoon. A cold front will pass 
through the area late in the afternoon and evening...which will 
bring some showers and thunderstorms to the area. Models are still 
resolving timing issues with the wave crossing the northern plains. 


Medium range models in decent agreement for the rest of the extended 
period. Slightly cooler air can be expected for Sunday into early 
next week...but still well above average. Another upper level 
disturbance and cold front will likely push through the region late 
Tuesday into Wednesday. 


&& 


Aviation...for the 06z tafs through 06z Friday night 
issued at 1120 PM MDT Thursday Mar 26 2015 


IFR conditions will continue over the northern Black Hills area 
where light rain continues along with snow across higher 
elevations. Another weak disturbance will move through the area 
tonight...with areas of light rain/snow and MVFR conditions. Gusty 
northwest winds will return Friday morning.

Unr watches/warnings/advisories...
