User blog:SPCBlackfordCounty995Main/When should Severe Thunderstorm Watch 178 be issued?

the SPC is saying in MD 598 (which just expired) that a downstream watch to 174 would be possible...just look at the MD itself. Mesoscale Discussion 598 NWS Storm Prediction Center Norman OK   0630 PM CDT Sat Apr 29 2017 Areas affected...Portions of southeastern MO and southern/central IL/IN Concerning...Severe Thunderstorm Watch 174... Valid 292330Z - 300030Z The severe weather threat for Severe Thunderstorm Watch 174 continues. SUMMARY...Mainly a damaging wind threat continues across Severe Thunderstorm Watch 174. Downstream watch issuance into Indiana is   possible. DISCUSSION...A line of thunderstorms is moving eastward along a   stationary boundary in east-central IL as of 2330Z. This line has produced multiple reports of strong/damaging winds over the past several hours. The airmass downstream of this convection and along/south of the boundary in central IN remains weakly to   moderately unstable, with MLCAPE ranging generally from 500-1500 J/kg, and veering low to mid-level flow should remain favorable for continued maintenance with this line for at least the next several hours as it moves into western/central IN. A downstream watch into IN may be needed in the next hour or so depending on convective trends. Farther south into southern IL and southeastern MO, the line of thunderstorms has become roughly parallel to mid-level southwesterly flow, and has made very slow southeastward progress. While strong to locally damaging winds and marginally severe hail remain possible across this region, they overall severe threat should remain rather isolated with southward extent. Notice the typo too, but does this mean that 178 could include my hometown?
