802 FXUS63 KDDC 060838 AFDDDC Area Forecast Discussion National Weather Service Dodge City KS 338 AM CDT Mon May 6 2024 .KEY MESSAGES... - Severe thunderstorms are expected from mid-day into the afternoon along and east of a line Scott City to Garden City. But these storms are expected to increase in severity farther east during early to mid afternoon, with very large hail and tornadoes expected. - The western limit of severe weather Monday depends on how early in the day storms develop. - Critical Fire Weather conditions are forecast This Afternoon and Tuesday afternoon in the west. - A mainly dry weather pattern will develop Monday evening and persist for several days. - There are small chances for rain next weekend. && .SHORT TERM /THROUGH TUESDAY/... Issued at 334 AM CDT Mon May 6 2024 Stratus was widespread this morning as moist south southeast winds provided moisture transport in the boundary layer. The clouds aided a steady temperature curve overnight as the entire area still remained in the low 60s as of 2 AM. A broad baroclinic leaf of cirrus cloud formed across from New Mexico across western Kansas and Nebraska while the upper synoptic trough approached the central rockies. A pacific cold front is poised to overtake the dryline by about 18-19z/1-2pm. Convective allowing models area favor initial convection developing on the northern periphery of this front, i.e. southern NE and northern into west central Kansas by around 17 or 18z (noon or 1 pm). This may lead to a few late morning hail and wind threatening severe storms while the southern reaches of the forecast area east of 283 remains in the warm sector, pooling moisture and heating up to drive surface based CAPE higher into the 2000-3000 J/kg area by the mid afternoon - meaning greater severe and tornado probability. In the area covering roughly , southern Stafford county, to Greensburg, Pratt and the southern reaches of the 183 corridor eastward, mean STP (significant tornado parameter) ramps up to values higher than 1, statistically correlated with supercells that tend to be tornadic. The slowest convective allowing model with exiting storms from the area ends the event for the DDC area by 6 pm. On Tuesday the area will be behind the frontal system with breezy westerly winds full insolation leading to widespread warm temperatures in the 80s. The opportunity to outperform is present with the 75th percentile of the NBM members showing high approaching 90 degrees in the southern counties so a 90 degree high temps would not be a surprise around Elkhart or Liberal. Despite the warm afternoon, the diurnal swing is large to the tune of 40 degrees as temperatures are forecast in the 40s over much of the area Tuesday night as a weak dry cold front moves through the area establishing breezy north wind. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Issued at 334 AM CDT Mon May 6 2024 The remainder of the week is a dry forecast, under light and generally northerly surface winds. The aforementioned front and the nature of the weak wind flow looks to cap highs in the pleasant 70s for each day Wednesday though Saturday. Slight chances for showers and thunderstorms return by Saturday as well, however it does not look like a widespread dynamic severe weather setup at this time. EC and GFS ensemble means both target the period from Monday/Tuesday through the week for light precipitation on the 24 hour ensemble Multi-runs. Plenty of consistency in the last 10 runs or so. The trend looks a little warmer as well with daily highs trending in the 80s. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1228 AM CDT Mon May 6 2024 Southeasterly moist upslope surface winds This Morning will maintain a stratus deck firmly in the IFR category as far east as Garden City, and perhaps Liberal. Most guidance does indicate visibility is leaning to remain above the LIFR category, but if visibility were to drop to one half mile or less the favored area would be the DDC terminal between 10 and 13z, as the HRRR model has a 40-60 percent chances of low visibility less than one half mile over south central Kansas. The ceilings will give way to a dryline in the mid morning hours, which could become the focus for scattered thunderstorm development between 15 and 18z anywhere form GCK to HYS . && .FIRE WEATHER... Issued at 334 AM CDT Mon May 6 2024 Widespread red flag meteorological conditions are expected each of the next 2 days across the western half of the area. The area hasnt been cleared of dry fuels for the season, however there may be some variability in the greenness withing the highlighted region. The red flag warning was expanded for all areas along the highway 23 corridor This Afternoon, with a areal matching Fire Weather Watch for Tuesday. Areas along the highway 283 corridor and eastward are considered too green to continue warnings for the time being. && .DDC WATCHES/WARNINGS/ADVISORIES... Red Flag Warning from 1 PM CDT /noon MDT/ this afternoon to 9 PM CDT /8 PM MDT/ this evening for KSZ043-044-061>063-074>077- 084>087. Fire Weather Watch from Tuesday afternoon through Tuesday evening for KSZ043-044-061>063-074>077-084>087. && $$ SHORT TERM...99 LONG TERM...99 AVIATION...99 FIRE WEATHER...99
