AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 234 PM CDT Thu Sep 19 2013 .SHORT TERM...(This Evening through Tonight) Issued at 234 PM CDT THU SEP 19 2013 This afternoon, a line of thunderstorms has developed along a cold front from southwestern Iowa through southeastern Nebraska into north central Kansas. This cold front will continue to dive southeastward toward the area this afternoon with thunderstorms entering northwestern Missouri by 3PM. These storms will have the potential to be severe with the initial concerns being damaging wind and marginal hail. Instability this afternoon is more than sufficient with MUCAPE values between 1500-2000J/KG. Moisture is plentiful with dewpoints in the mid 60s to near 70. Mid level lapse rate are moderate which would support small to marginally severe hail possible this afternoon into the early evening. The low level lapse rates will be strong, and couple this with good vertical shear and, damaging winds will most likely be the main threat with little bowing segments possible. Another possible concern with these storms will be heavy rainfall as PWAT values are in the 1.50"-2.00" range and training may be a concern as winds parallel the boundary with this slow moving front. Although widespread flooding is not a concern with the recent dry conditions across the area, localized flooding will be possible if heavy rains train across the same area especially ones that are flood prone. Otherwise, these storms will continue to drop southeast with the front during the overnight hours with many areas picking up 1"-2" of precipitation and some local area picking up even more. This front will clear the area by Friday morning with just a few remaining showers across the extreme southern CWA around sunrise. .LONG TERM...(Friday through Thursday) Issued at 234 PM CDT THU SEP 19 2013 Friday-Sunday: A spectacular weekend is in store for the region as high pressure takes control on Friday. Lingering showers will quickly clear Friday morning, with skies clearing through the day. With fairly strong cold advection moving across the area, temperatures will only climb into the middle 70s in most areas. Little to no change in the forecast for the weekend as temperatures in the 70s are expected under a sunny sky. In response to mid-level troughing crossing the Rockies on Sunday, winds will turn to the south and usher in slightly warmer readings. Monday-Wednesday: The aforementioned mid-level trough will quickly sweep through the region on Monday, pulling limited moisture eastward through the Plains. A few scattered showers or thunderstorms will be possible as this wave moves through, however the highest rain chances will focus themselves over the Northern Plains on Monday. Dry conditions and warmer temperatures will return for the middle to end of next week as a large trough forms over the western third of the CONUS. Deep southwesterly flow will push high temperatures back above normal towards the upper 80s. Have bumped up temperatures a few degrees over populated guidance. && .AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon) Issued at 1236 PM CDT THU SEP 19 2013 Outflow boundary heading toward STJ appears to be washing out and morning showers and thunderstorms that were approaching the terminal have diminished. The main concern for aviators for the remainder of today will be a cold front which is currently extending from near Omaha to Great Bend. This front will continue to progress southeastward through the afternoon. Thunderstorms are expected to redevelop on this frontal boundary this afternoon and move into the terminals between 22Z-01Z. These storms are expected to form into a slow moving line of thunderstorms with periods heavy rainfall between 01Z-05Z at MCI. Stronger storms may be capable of strong winds of 30-50kts however difficulty in forecasting timing of these winds preclude a TAF mention. Otherwise in heavier storms there will be periods of temporarily reduced vsbys to 1-3SM as well as occasional MVFR cigs. Thunderstorms will continue through 06Z-09Z with no cig/vis restrictions and showers will end by 07Z-09Z. Winds will be out of the south-southwest out ahead of the cold front around 15kts with gusts around 25kts. FROPA will occur at the terminals between 01Z-03Z with wind veer to the northwest behind the front between 7-12kts. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE.
