Area forecast discussion, Apr 28, 2:40 PM CST, 2 hours 35 minutes before
AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 340 PM CDT Sun Apr 28 2019 .Discussion... Issued at 337 PM CDT SUN APR 28 2019 Primary forecast focus is spread across the next several days. Currently, through 1 PM CDT, isolated showers/thunder have cropped up across portions of east central Kansas. This activity appears to be isentropically driven, supported by a stout low level jet. south easterly surface/boundary layer flow continues to transport moisture laden air northward. Updrafts are being supported by decent shear profiles. Overall, instability is not overly impressive, expect this early activity to be more a nuisance, with isolated showers/thunder moving east and northeast through the region late this afternoon and into the evening, preceding new storm development later tonight. Later this evening, after this afternoon round, more organized convection will develop across central Kansas, moving eastward through the evening, influenced by the push of a surface trough off the western high plains. Not to re-hash the SPC Day 1 outlook, but ongoing convection will merge, more or less, into a loose complex as they move into western Missouri between 10 PM and Midnight. With the surface trough moving nearer after midnight, expect an increase in potential for strong to severe storms between 1 and 4 AM in far eastern Kansas and western Missouri. With modest southeast flow at the surface, shear profiles will be supportive of decent updrafts. Primary concern is hail and wind, but a brief tornado cannot be ruled out given low level shear profiles. Do not let overnight storms catch you off guard. Be sure you have a reliable warning source, NOAA weather radio, Phone Apps, etc. Do not rely on outdoor warning sirens while you sleep. Storms will linger through sunrise, exiting to the east and southeast through the day. We'll have a brief reprieve from rain, Monday afternoon/evening, before the next, more prolonged and heavier, round moves in early Tuesday Morning. After collaborating with our neighboring office, it was decided to not issue a Flood Watch at this time, but periods of prolonged moderate to heavy rain are likely Tuesday through Wednesday Morning. Additionally, strong to severe storms are possible into the afternoon. The 500mb short wave will lift east northeast through midday, with a ribbon of instability and decent deep layer shear across western Missouri and eastern Kansas. This, pared with a strong low level jet, it's looking more likely a period of strong to severe storms, with hail and wind the primary concerns. As for rainfall, between tonight (4/28) through this coming Wednesday, anywhere from 2 to 3 inches can be expected across most of the region, with isolated areas of 4 to 6 inches possible. Flooding of creeks, streams, low lying areas, the usual suspects is going to happen. Do not drive through flooded roads. A Flood Watch will more than likely be issued either tonight or tomorrow. && .Aviation...(For the 18Z TAFS through 18Z Monday Afternoon) Issued at 337 PM CDT SUN APR 28 2019 Isolated showers and thunderstorms will continue to impact area airfields through through 29/00z. Shower and thunderstorm chances will increase later tonight and continue through early Monday morning. This will pair with IFR ceilings, which will linger through sunrise. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...Kurtz Aviation...Kurtz
