656 FXUS63 KDVN 200551 AFDDVN Area Forecast Discussion National Weather Service Quad Cities IA IL 1251 AM CDT Sat Jul 20 2024 .KEY MESSAGES... - Pleasant summer weather is forecast through this weekend with only slight chances for isolated showers and storms on Sunday. - Increasing humidity next Monday - Wednesday will lead to occasional chances for scattered showers and storms. - Moderate to major river flooding continues on the Mississippi River. The Rock River will crest in the Moderate category at Joslin and Moline this weekend. && .SHORT TERM /THROUGH SUNDAY/... Issued at 240 PM CDT Fri Jul 19 2024 Scattered to broken high-based cumulus clouds will quickly dissipate by sunset, leaving a clear night with calm winds. Lows will bottom out mainly in the upper 50s. On Saturday, weak low pressure, surface and aloft, will drift from SD to nw IA. Increasing mid/high clouds can be expected but the forecast soundings indicate very dry low levels. Therefore, not expecting any rain reaching the ground (Sprinkles perhaps?). Highs will be in the upper 70s at most locations, along with tolerable humidity levels (dewpoints in the lower 60s). && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... Issued at 240 PM CDT Fri Jul 19 2024 Split flow with a cut-off low will slowly meander across the Corn Belt. Shear will be weak and lack of Gulf moisture should keep severe weather and heavy rainfall in check. There looks to be a daily chance for scattered showers and a few thunderstorms, mainly in the afternoon and evening hours. Pops from Sunday through Wednesday are only in the 20-40 percent range each day. Significant rainfall is not expected. Daily highs should be in the lower 80s with lows in the lower to mid 60s, which is near normal for mid July. && .AVIATION /06Z TAFS THROUGH 06Z SUNDAY/... Issued at 1241 AM CDT Sat Jul 20 2024 VFR and light winds will continue with high pressure in control. A few sprinkles are possible tonight through Saturday morning, mainly at CID and BRL. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...None. IL...None. MO...None. && $$ SHORT TERM...Haase LONG TERM...Haase AVIATION...Uttech
