608 FXUS63 KSGF 010705 AFDSGF Area Forecast Discussion National Weather Service Springfield MO 205 AM CDT Mon Jul 1 2024 .KEY MESSAGES... - Heat and humidity return on Tuesday through Thursday. - Thunderstorm chances increase Wednesday through Friday. - Slightly cooler temperatures over the weekend. && .SHORT TERM /THROUGH TUESDAY/... Issued at 205 AM CDT Mon Jul 1 2024 Synoptic overview and current conditions: Water vapor imagery and upper level analysis show a large upper level high pressure system over the southern plains and lower Mississippi valley with a ridge axis extending north into the central and northern plains. An upper level trough was shifting east out of the Pacific northwest into the northern Rockies. Shortwave energy was pushing over the top of the ridge and instigating some convection over the plains. A moisture axis extended from the lower Mississippi valley into the central plains with some low level warm advection taking place over central KS. This was aiding in some shower development over central into eastern KS early this morning. Temperatures across the areas were in the upper 60s to mid 70s with dewpoints from the mid 50s in parts of the eastern Ozarks to the upper 60s across the south. Rest of tonight into Monday: A few of those showers may make it into west central Missouri towards sunrise, but the bulk of any convection should remain north of the area during the rest of tonight into this morning. Most of the area should remain dry today. The upper level ridge axis will shift east over the area with the main upper energy remaining well to the northwest of the area. The surface high will continue to shift more eastward and our winds towards the end of the day will start to become more southeasterly. Moisture advection from the Gulf will start to increase over our western CWA. Highs today should reach the low 90s in the far west, but only the upper 70s to low 80s in the east. Heat index values in the west will be in the 100 to 103 degree range, but remain in the low 80s out east. Tonight and Tuesday: The upper level ridge axis will shift east of the area as the upper trough pushes east into the northern plains and upper Mississippi valley. A frontal boundary will start to approach from the northwest, but should remain northwest of the area through 00z with little or no precipitation expected. Temperatures and humidity will increase over the area, with highs returning to the low 90s in the east and the mid and upper 90s in the west. Heat index values over teh western half of the area will be in the 105 to 108 degree range and will likely eventually need a heat advisory, while in the east remain in the mid 90s to around 101. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Issued at 205 AM CDT Mon Jul 1 2024 On Tuesday night, the upper level flow will become more westerly as the upper ridge flattens out from the southern plains into the southeast U.S. The frontal boundary will push into the area and become more west-east oriented over the area while upper energy pushes across the region. High moisture content is expected over the area with PW values over 2" across the area. Thunderstorm chances will increase over the area through Thursday night(50-70%) with the potential for heavy rain with highest totals at this time expected to be over the northern half of the CWA. Temperatures will be highly dependent on how much can clear out during the daytime on Wed/Thu but we are going with low 90s in the north to the upper 90s in the south with heat index values from the upper 90s in the north to 105-110 in the south both days. The front pushes further to the south over the weekend with slightly cooler air moving into the area and pushing the better rain chances to the south as well. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1201 AM CDT Mon Jul 1 2024 For the 06z TAFS, keeping an eye out west in KS at some convection starting to develop in central KS in an area of warm air advection with some minor MU CAPE. CAMS generally take this convection north of the TAF sites and for now have kept out of the 06z TAFS. Will continue to see VFR ceilings through the night and into Monday with winds continuing to gradually veer from the east to the east-southeast. && .CLIMATE...
