000 FXUS63 KDVN 242336 AFDDVN Area Forecast Discussion National Weather Service Quad Cities IA IL 636 PM CDT Tue Sep 24 2024 .KEY MESSAGES... - At or slightly above normal temperatures the rest of the week that become at or slightly below normal over the weekend. - Dry conditions to prevail Wednesday into Friday. - Potentially active weather late week and into early next week but there is high uncertainty regarding the rain and any impacts. && .SHORT TERM /THROUGH TONIGHT/... Issued at 258 PM CDT Tue Sep 24 2024 This Afternoon and Tonight, an upper low will continue to drop SSE across the western and southern CWA. Bumped up POPs for this afternoon in the SW CWA. This activity is expected to diminish towards sunset with clearing skies forecast for the remainder of the night. Winds will become nearly calm, so there is the possibility for some fog late tonight and early Wednesday. Have some aviation fog mentioned for BRL, but opted to keep mention out of grids as confidence is low. Lows will be in the upper 40s to lower 50s. && .LONG TERM /WEDNESDAY THROUGH TUESDAY/... Issued at 258 PM CDT Tue Sep 24 2024 Wednesday through most of Friday, dry conditions will prevail as high pressure builds into the area. The upper low will continue to drop south into SE MO. There still remains some uncertainty on whether the upper low to the south may bring some rains back into the south and southeast part of the CWA. Through collaboration, believe the drier NE flow will keep rain at bay initially and opted to cut POPs Friday. There is still some slight or chance POPS south of I-80 Friday, but believe the downward trend will continue and it may be a predominantly dry day for all. Saturday through Monday, there remains a good deal of uncertainty with whether any tropical remnants get ushered NW into the area as the upper low to our south interacts with the system. How far south and southeast the upper low gets will hinder the chances of tropical moisture getting this far NNW. At this time, the current blend seems reasonable given the uncertainties. The current best chances (30 to 50 percent) for rain for Friday night and Saturday, with 20 to 40 POPS focused across the SE half of the CWA through Monday. Highs through much of the long term are slated for the mid 70s to near 80. Cooler readings would be possible for the weekend if rain chances increase. There is still some time to work out details as we get future model runs. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 631 PM CDT Tue Sep 24 2024 VFR conds for much of this taf period. The exception will be at KBRL/KMLI 06-14z/25 for the potential for MVFR BR due to calm winds and moist ground from recent rain. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...None. IL...None. MO...None. && $$ SHORT TERM...14 LONG TERM...14 AVIATION...Haase
