Area forecast discussion, Jun 29, 11:08 AM MST, 2 hours 48 minutes before
Area Forecast Discussion For Western SD and Northeastern WY National Weather Service Rapid City SD 1208 PM MDT WED JUN 29 2016 .UPDATE... Issued at 940 AM MDT Wed Jun 29 2016 Current surface analysis shows low pressure over north central WY, with frontal boundary extending south-southeast along the lee of the Rockies and into southwest KS. Upper level analysis shows ridge remaining over the Rockies region, with northwest flow across the Northern Plains. A few showers have been noted across northeast WY and northwest SD this morning, with partly cloudy to mostly sunny skies across the cwa. Temps at mid morning are in the upper 60s and 70s. Winds are mostly light and variable. Have updated the forecast to remove early morning fog and to adjust sky cover some for the rest of the morning. Also raised highs a couple of degrees in most areas. No changes to forecast for later today with regard to thunderstorm chances and threat for severe wx. Best chances will be from the Black Hills area and southward, similar to yesterday. UPDATE Issued at 623 AM MDT Wed Jun 29 2016 A line of fog/low clouds has developed along the northeastern foothills and towards Philip, so added mention to grids for early this morning. Some weak storms continue to track southeastward across northwestern SD, and showers are beginning to move into northeastern WY. && .SHORT TERM...(Today Through Thursday Night) Issued at 146 AM MDT Wed Jun 29 2016 With high pressure over the Four Corners, upper ridge covers the western states, putting the northern plains in continued northwest flow. Next upper wave to affect the region is over northern MT. There are a few clouds across northeastern WY...and some weak storms over northwestern SD. Winds are light and variable, and temps are in the 50s and 60s. Weak upper wave will move over the northern Rockies today. At the surface, easterly flow will continue to advect in moist air with upper 50s to lower 60s dewpoints. MLCAPE of 1000-2000 J/kg will develop across the area this afternoon, as well as 0-6 km shear around 50 kts. Conditions look similar to yesterday, except for slightly less instability and shear. Also similar to yesterday, hi-res convective models differ in timing/location/mode...agreeing only that there will be storms somewhere. Nonetheless, conditions are favorable for large hail and damaging winds again today. Highs will be in the 80s. Tonight, a Canadian low pressure system will drag a cold front through the region, and high pressure will begin to settle into the northern plains. Return flow will develop over the southwestern CWA, resulting in some weak instability there. Decent shear will aid in thunderstorm development along and south of the front, while dry conditions are expected across much of the western SD plains. Highs Thursday will be cooler, around 80. .LONG TERM...(Friday Through Tuesday) Issued at 146 AM MDT Wed Jun 29 2016 West to northwest upper flow will continue through the extended period with the upper ridge to the west flattening and the flow becoming more zonal for the beginning of next week. Relatively moist southeasterly flow will prevail at the surface. A series of upper level disturbances will combine with the persistent flow of low and mid level moisture to aid in the development of diurnal convection over various parts of the forecast area each day. On most days the coverage will be limited, with only isolated to scattered thunderstorms. Deep layer shear will support the threat of severe storms, however the general lack of strong upper level forcing will keep the coverage of severe storms limited. Slightly cooler than average temperatures will occur on Friday, then temperatures will warm through the weekend, becoming around 10 degrees warmer than average for the beginning of next week. && .AVIATION...For the 18Z TAFS Through 18Z Thursday Issued At 1202 PM MDT Wed Jun 29 2016 Shwrs and tstms wl dvlp ovr nern WY and the Blk Hls this aftn, some possibly severe w/ lg hail and strong straight line wnds and localized MVFR cigs in vcnty of storms.
