NWS Forecaster Discussion




Area forecast discussion for western South Dakota and northeastern Wyoming 
National Weather Service Rapid City South Dakota 
1132 PM MDT Thursday Jul 2 2015 


Short term...this evening through Friday night 
issued at 210 PM MDT Thursday Jul 2 2015 


Current surface map shows a weak area of high pressure sliding 
into our County Warning Area from southeastern Montana. Clear skies from this 
morning have allowed the surface to heat up and erode the small 
cap that was in place...and scattered showers and thunderstorms 
have already developed across western South Dakota. Not 
anticipating any severe weather this afternoon...though there 
could be an isolated strong storm in southwestern South Dakota 
where the strongest shear and instability align. After the sun 
sets this evening...expect showers and thunderstorms to die down. 


The region will continue to be influenced by high pressure during 
the day on Friday...and with the exception of the Black Hills during 
the afternoon...most areas should remain dry. By Friday 
evening...any thunderstorm and shower activity should taper down. 


Long term...Saturday through Thursday 
issued at 210 PM MDT Thursday Jul 2 2015 


Under northwest flow aloft...very warm and mostly dry weather is 
expected on Independence day...with isolated to widely scattered 
showers/storms possible in the afternoon...especially over the 
Black Hills area. Shear and instability look sufficient for strong 
to severe storms if they develop. Southerly low level jet over the 
Central Plains Saturday night could fuel more thunderstorm 
development...especially toward south central South Dakota. Stronger 
shortwave energy is prognosticated to rotate around a Canadian low 
pressure system on Sunday...along with a cold front...bringing 
more widespread and better chances for showers and storms Sunday 
into Sunday night. Severe storms certainly look possible across a 
good portion of the forecast area...depending on the timing of the 
system. 


Flow aloft early next week will become more zonal...which would 
bring weak disturbances across the area Monday and Tuesday. Will 
keep low chance probability of precipitation across much of the area...especially southern 
and western portions of the County Warning Area. A better chance for showers and 
storms will likely develop around midweek. Temperatures look to be 
slightly below average for much of next week.

Aviation...(for the 06z tafs through 06z Friday night) 
issued at 1131 PM MDT Thursday Jul 2 2015 


VFR conditions generally expected through the period. Smoke from 
Canadian wildfires will continue across the area...with visible 
restrictions down to around 6 miles at times. Otherwise...sct- 
isolated rain showers/ts are possible once again over the Black Hills Friday 
afternoon.

Unr watches/warnings/advisories...
