NWS Forecaster Discussion




Area forecast discussion for western South Dakota and northeastern Wyoming 
National Weather Service Rapid City South Dakota 
539 PM MDT Sat Apr 19 2014 


Short term...this evening through Sunday night 
issued at 210 PM MDT Sat Apr 19 2014 


Upper level analysis has cut off lows across Manitoba and Arizona 
with near zonal flow across the northwest Continental U.S.. next upper trough just now 
making its way into the Pacific northwest. Skies are sunny with 
some middle level clouds crossing south central South Dakota. At the 
surface...high pressure is located across the northern and Central 
Plains. Temperatures are in the 50s and 60s with variable and 
breezy winds in spots. 


Warm weather will persist through Sunday as high pressure at the 
surface and aloft remain over the area. Warmer air will return 
tonight and Sunday as winds shift to the south-southeast. Sunday 
will see temperatures in the 70s to near 80 degrees. The next cool 
front will push into the area in the afternoon and 
evening...bringing brisk northwest winds behind it. There will be 
a slight chance of showers and thunderstorms across portions of 
southwest and south central South Dakota for later in the afternoon and 
evening as the front crosses. Short range models are in pretty 
good agreement on this possibility...with low level moisture and 
instability likely sufficient for isolated activity in these 
areas...though the forcing looks to be relatively weak. Dry 
weather returns for Sunday night.

Long term...Monday through Saturday 
issued at 210 PM MDT Sat Apr 19 2014 


An upper level ridge will bring warmer than average temperatures 
to the northern plains on Monday and Tuesday. Forecast models 
continue to show an upper level trough affecting the area from 
Tuesday night through Thursday. Latest runs show the European model (ecmwf) is 
favoring slightly faster movement to the system and is also 
farther north with the upper low compared to the latest GFS 
solution. In general the result will be increasing chances for 
precipitation Tuesday night into Thursday as well as increasing 
gradient/wind for Wednesday/Thursday as surface low develops over 
the Dakotas and wraps up over the upper Midwest. General chance 
probability of precipitation still warranted with temperatures cold enough at night for a 
bit of snow in the higher elevations Wednesday night/Thursday 
morning and then on the plains Thursday night. Model solutions 
diverge for Friday and Saturday due to the differences in speed 
and timing of the eastward progress of the upper trough on 
Friday and the timing of the next trough approaching from the west 
on Saturday.

Aviation...for the 00z tafs through 00z Sunday evening 
issued at 538 PM MDT Sat Apr 19 2014 


Southerly winds tonight will shift to the northwest 
Sunday as a cold front passes through the area. VFR conditions will 
continue through Sunday afternoon. There is a slight chance of 
thunderstorms over parts of southwestern and south central South 
Dakota on Sunday afternoon.
