NWS Kansas City, MO wrote its last area forecast discussion before the first event at Apr 15, 5:36 PM CST, 49 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 636 PM CDT Sat Apr 15 2017 .Discussion... Issued at 301 PM CDT SAT APR 15 2017 Sufficient mixing has permitted increased 850 hPa winds out of the southwest to translate to the surface, with observed wind gusts up to 35 to 40 mph across the area. While gusts will taper off after sunset, increased surface winds will persist ahead of a cold front expected to push through northwest Missouri this evening. Within the ongoing southwesterly low level flow, dew point values have increased into the low 60s as of Saturday afternoon. While ascent has been lacking across the area due to a capped environment, this is expected to erode with frontogenetical support this evening along the cold front. The upper-level forcing of this boundary is centered over the Northern Plains with an attendant surface low positioned near the Great Lakes Region. This will create parallel surface flow along the cold front locally, thus decreasing overall surface convergence into the boundary. This in turn will act to decrease the overall tornadic potential along the front, though small hail and strong winds will remain possible along the boundary, particularly as storms merge near central Missouri. With that said, the overall severe threat is relatively low, given the displaced upper dynamics, which will remain well north of the area. Considering the linear nature and relatively progressive nature of the storms, rainfall totals should mostly be limited to 0.5" to perhaps 0.75" tonight into Sunday morning. With the displaced upper-level pattern becoming zonal by Sunday, the frontal boundary will stall across central Missouri, well south of the I-70 corridor. The boundary will act as forcing for additional storms to develop Sunday afternoon along and south of the stalled front. While severe weather is not anticipated with activity on Sunday, river levels and streams in this area will need to be monitored as this boundary slowly lifts back to the north as a warm front Sunday night through Monday morning. The active pattern will continue through the early work week as a mid- level shortwave advances north of the CWA Tuesday morning. Latest guidance depicts this feature further north compared to previous runs, thus lessening the overall forcing, and particularly the hydrologic concerns during this time. What this will equate to, however, is additional chances of storms through early Tuesday before a subsequent cold front pushes through the local area Tuesday night. While severe weather is possible during this time period, ongoing precipitation throughout the day will likely limit this potential, not to mention the fact that upper-level dynamics will once again be displaced. Storm chances will continue off and on throughout the week, with seven day rainfall totals expected to reach near three to four inches by the time all is said and done. && .Aviation...(For the 00Z TAFS through 00Z Sunday Evening) Issued at 636 PM CDT SAT APR 15 2017 Note: The TAF for KSTJ will be NIL through the weekend due to missing observations at the terminal. Observations are not anticipated to return until Monday. VFR conditions will give way to thunderstorm activity later this evening as a cold front sweeps southeast across the region. Many question still exist as to CIGs and VIS as the storms move threw; so anticipate updates to the TAFs as the storms approach the terminals. Expect the gusty winds to persist ahead of the front, but to quickly veer to the northwest and north behind the front tonight and into tomorrow. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE.
