Issued at 327 AM CDT Wed Jun 19 2024 An upper level ridge of high pressure is located across the eastern U.S as an upper level trough is located over the eastern U.S. early this morning. The upper ridge will start to move back to the east late today into the end of the week. Convection has developed ahead of the trough across central KS early this morning. This activity will not make a lot of eastern movement today as the upper level trough and better lift remains west of the area today. Therefore, coverage in this activity will decrease as it moves east. Some weak upper level energy will move north across the area this afternoon/evening west of the upper level high. Instability will be on the weaker side today and a drier air mass will be in place in the mid to upper levels of the atmosphere. Some isolated showers and a few storms will be possible this afternoon and evening, but with the drier air and the amount of instability in place, coverage will be limited, and many locations will not be affected. Deep layer shear will also be on the weaker side today, so no severe storms are expected across the area today. Highs will warm into the upper 80s to around 90 this afternoon with heat index values in the lower to middle 90s. Lows tonight into Thursday morning will be in the middle 60s to around the 70 degree mark. The upper level ridge will build back to the west into the area on Thursday. Drier air and weak instability will be in place with mainly dry conditions expected Thursday. Highs will again warm into the upper 80s to around 90 with heat index values in the lower to middle 90s.

Issued at 327 AM CDT Wed Jun 19 2024 The upper level ridge will be over the region Friday into the weekend. Highs will warm into the lower to middle 90s, with heat index values in the upper 90s to around 100. An upper level trough will flatten the ridge Saturday night into Sunday and could bring some scattered showers and storms to the area (10 to 30% chances). There are are still questions on how far south this activity can make it Saturday night into Sunday as the better upper level support remains north of the area. Not all locations will be affected by this activity, with chances decreasing from north to south. An upper level ridge of high pressure will build over the Plains early next week. This could level the area in an upper level northwest flow pattern and could allow some scattered shower and storm chances at times early next week. A warm air mass will also remain in place with highs in 90s and heat index values around 100 degrees early next week. Lows will only cool into the low to mid 70s this weekend into early next week.

Some isolated showers and thunderstorms will be possible from the late morning into the early evening hours on Wednesday. Coverage will be limited and not all locations will be affected. Left any mentioned of convection out of the TAFs do to low confidence in activity forming and affected the TAF sites due to limited expected coverage. Otherwise VFR conditions are expected through the TAF period. && .CLIMATE...
