706 FXUS63 KDVN 300549 AFDDVN Area Forecast Discussion National Weather Service Quad Cities IA IL 1249 AM CDT Thu May 30 2024 .KEY MESSAGES... - Quiet weather is forecast through Thursday with high temperatures in the lower to mid 70s. - There are several chances for showers and storms Friday night through early next week. && .SHORT TERM /THROUGH FRIDAY/... Issued at 159 PM CDT Wed May 29 2024 Broad high pressure stretching from the upper Great Lakes into the mid-Mississippi River Valley was providing a beautiful, quiet afternoon to all of eastern Iowa, northwest Illinois and northeast Missouri. Other than some diurnal CU, skies features plenty of sun with temperatures in the upper 60s to low 70s. This high will slowly move east over the next 24-36 hours, and will continue to influence our weather during the short term period. Expect clear to partly cloudy skies, with lows tonight in the 40s/50s and highs Thursday in the mid to upper 70s. Winds will be light & variable tonight, and will increase out of the southeast Thursday to around 10-15 MPH. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Issued at 159 PM CDT Wed May 29 2024 Thursday Night through Friday night... High pressure will be nearly out of the area Thursday night, but we should remain dry with increasing clouds ahead of an approaching shortwave. Temperatures will vary depending on cloud cover, with cooler values near 50 in far northwest Illinois and values near 60 in east central Iowa and northeast Missouri. For Friday, much of the day will be dry before chances of showers and thunderstorms increase with the approaching positively tilted shortwave to the west. The threat is most favored during the late afternoon and evening areawide, with the NBM continuing to show chances around 50-60%. There is still some disagreement amongst deterministic guidance on placement, so look for additional refinements to this forecast. The threat of severe weather is low with higher instabilities remaining to our west. Saturday on... A shortwave filled zonal flow will be in place across the area this weekend into early next week, which favors shower and storms chances each day. However, there will be plenty of dry time between each system so not expecting a total washout. Confidence in a severe weather threat is low at this time, though I think we`ll need to keep an eye on early next week as instability increases with warming temperatures and moisture. Speaking of which, temperatures will gradually warm with highs back near 80 Saturday. The warming trend will continue into early next week, with highs in the mid to upper 80s by Tuesday. && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
