Issued at 318 PM CDT Wed Jun 12 2024 Today and tonight... An upper level ridge is centered over Arizona and New Mexico with northwest flow over south central and central Nebraska and north central Kansas. A strengthening surface trough to the northwest has resulted in gusty southwest winds across most of the area. Temperatures are also heating up with highs expected to reach the mid 90s to around 100 degrees. The winds will weaken this evening into tonight with the surface trough still across the area. Low temperatures tonight will range from the mid 60s to lower 70s. Thursday and Thursday night... A cold front associated with an upper trough moving over southern Canada and the Upper Midwest will move into Nebraska and Kansas on Thursday. Gusty, northerly winds are expected behind the front with a surface trough along and ahead of the front. Temperatures will be cooler than the previous day for much of Nebraska on Thursday due to the passage of the front. However, temperatures across far southern portions of Nebraska and north central Kansas will be similar or slightly warmer than the previous day. High temperatures on Thursday are expected to range from the mid 80s to around 100 degrees. Heat index values will generally range from near 100 to near 105 degrees for areas along and ahead of the front. Showers and thunderstorms may impact (15% to near 25% chance) areas generally south of the Tri- Cities Thursday afternoon into Thursday night. The highest chances for storms will be in north central Kansas. High CAPE and mid-level lapse rates are expected Thursday afternoon into Thursday evening according to the NAM12 along and ahead of the cold front. Modest wind shear is also expected along with increased lift across the area. These conditions will allow for some of the storms to become strong to severe. Large hail and damaging winds will be the main threats. Winds will weaken across the area Thursday night with lows in the upper 50s to upper 60s. Friday and Friday night... The upper ridge moves more over the southern and central Plains on Friday. Winds will become breezy out of the southeast across south central and central Nebraska and north central Kansas. Upper shortwaves will be moving over the area on Friday providing enhanced lift. CAPE and wind shear will be fairly modest across most of the area on Friday according to the NAM12. Shower and thunderstorm chances will be 15% to around 40% on Friday and will increase up to near 85% Friday evening/night. Most of the forecast area is outlooked in a slight risk for severe weather Friday into Friday night according to the Storm Prediction Center. High temperatures on Friday will generally be in the 80s with some lower 90s. Low temperatures Friday night will mostly be in the 60s with some lower 70s with southeast winds. Saturday through Tuesday night... A shortwave/upper trough will be moving over the central Plains on Saturday. This will allow for chances up to around 40% of showers and thunderstorms for Saturday and Saturday night. High temperatures will range from the mid 80s to mid 90s with southerly winds. Low temperatures Saturday night will range from the low 60s to low 70s. Temperatures will increase even more on Sunday with highs generally in the upper 80s to upper 90s with mostly sunny skies. Low temperatures Sunday night will be in the upper 60s to mid 70s. An upper trough approaching from the west will be over most of the western half of the country on Monday. High temperatures on Monday will be similar to those from the previous day. The upper trough will begin to lift northeastward Monday night with a cold front approaching the area. The cold front may already be moving through the area by Tuesday morning. Low temperatures Monday night will depend on the timing of the front but expect them to generally be in the low 60s to mid 70s. The cold front will finish moving through the area on Tuesday with high temperatures expected to range from the mid 70s to lower 90s.
