Area Forecast Discussion National Weather Service Quad Cities IA IL 645 AM CDT Wed Jun 1 2022 ...HYDROLOGY UPDATE... .SYNOPSIS... Issued at 312 AM CDT Wed Jun 1 2022 Cold front extends along a Freeport IL to Macomb IL line as of 2 AM. Regional radar imagery shows widespread showers and storms over portions of MO into central IL which has been expanding/developing northward into our southern counties, as an mid level wave approaches southwest of Kirksville MO. Post-frontal, cooler and drier air was being ushered into the area on NW winds, with temps lowering through the 60s and dew points dropping into the 50s. Pattern aloft is WSW and features additional energy into the Rockies, which is aiding widespread precipitation over Colorado. This system looks to shift east- northeast and bring showers back to the region by tonight. && .SHORT TERM...(Today and Tonight) ISSUED AT 312 AM CDT Wed Jun 1 2022 Showers and storms should diminish across the southern counties by mid morning, as the mid level wave departs. Otherwise, pleasant conditions are in store today with northerly winds continuing to usher in cooler and drier air on northerly winds. Highs look to be mainly in the 70s with primarily filtered sunshine the best many areas will see today between high cloudiness and then arrival of mid clouds later this afternoon into early evening ahead of approaching Rockies wave. By late afternoon and especially tonight, transitory bout of lift will overspread the area attendant to a passing shortwave and upper jet entrance region. This will aid top down saturation, The drier air in the low levels (at or below 6kft agl) will lead to challenges with light measurable rain potential and thus the reason for capping PoPs into chance category also in line with GEFS probs of 0.01 inch or more of precip. This should end from west to east by mid to late evening into the early overnight, and followed up by decreasing clouds. This will allow cooler lows in the upper 40s to lower 50s into western portions of the service area, with mid 50s east where clouds last to decrease. .LONG TERM...(Thursday through Tuesday) ISSUED AT 312 AM CDT Wed Jun 1 2022 Key Messages 1) Turning dry and more seasonable for the end of the work week 2) Active weather returns for the weekend with renewed zonal flow aloft Discussion Thursday through Friday Night... High pressure will build into the Midwest early on. This high will slowly move through the mid-Mississippi River Valley, and will exit the area by Friday night. A resurgence of northwest flow will usher in more comfortable (dewpoints in the 40s/50s) conditions and a late spring-like air mass across the area with highs Thursday and Friday in the mid to upper 70s (overnight lows in the 40s/50s). Skies should feature plentiful sunshine during the days and mainly clear skies at night. Saturday through Next Week... Zonal flow will return just in time for the weekend with several embedded shortwaves aloft in tow. Nearer to the surface, a warm front is forecast to surge back north into the Midwest with a return of warmth and humidity to the area. With this will come a chance for rain and storms, which look to persist from this weekend into the start of the work week. There are chances each day, but nothing definite at this point as deterministic guidance is not in good agreement on timing and precip location. && .AVIATION...(For the 12Z TAFS through 12Z Thursday Morning) ISSUED AT 535 AM CDT Wed Jun 1 2022 VFR conditions expected through the period. A shower is possible at BRL over the next couple of hours before a system to our south begins to pull away. Tonight, a fast moving disturbance will bring a chance of showers to the terminals ending from west to east late evening into the overnight. Dry air at or below 6kft agl should preclude impacts and keep any measurable amounts light. Winds will be light predominantly from a northerly direction today, then variable tonight. && .HYDROLOGY... Issued at 636 AM CDT Wed Jun 1 2022 Have upgraded the La Moine River at Colmar to moderate flooding. Initially runoff from areal basin average rainfall of 2-3+ inches last night pushed it into minor flood category, but now the routed flow has kicked in resulting in another rise with the forecast calling for it to reach moderate flood stage before beginning to fall this afternoon. It's possible the river could crest a few tenths of a foot above 22 feet and possibly near 22.5 feet, which is when water affect lower roads around Birmingham. Another update is expected later this morning with additional crest changes possible as more rainfall reports come in. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE. IL...NONE.
