Area Forecast Discussion National Weather Service Quad Cities IA IL 251 AM CDT Fri Jun 17 2022 .SYNOPSIS... Issued at 250 AM CDT Fri Jun 17 2022 Quiet weather was in place over much of eastern Iowa and northwest Illinois early this morning, with surface analysis indicating showing expansive high pressure and ridging extending over the Midwest and Upper Mississippi River Valley from the Dakotas. To the south, showers and strong storms were ongoing along the cold front in northeast Missouri and far southeast Iowa. Storms were producing torrential rain, frequent lightning and hail. As of 2 AM, temperatures ranged from 61 in Independence to 75 in Keokuk. && .SHORT TERM...(Today and Tonight) ISSUED AT 250 AM CDT Fri Jun 17 2022 [Key Messages] 1) Strong to severe storms in southeast Iowa and northeast Missouri early this morning. 2) Very warm and dry with lower humidity expected to close out the work week [Discussion] Storms in far southeast Iowa and northeast Missouri will slowly come to an end this morning as the cold front continues to slowly sag to the south. Storms could be strong to severe as they exit, with mainly large hail and winds the primary threat. The Storm Prediction Center maintains a Level 2 (slight) risk of severe storms over mainly northeast Missouri. Storms will produce torrential rainfall as well with plentiful convergence along the boundary, high amounts of moisture availible, and storm motion parallel to the boundary promoting training. Once storms exit, high pressure will build into the area, allowing for dry and less humid conditions to close the weekend. Temperatures will remain very warm given our sun angle and prolonged days, with highs climbing into the low to mid 80s, and lows tonight dropping into the 50s and 60s tonight. Dewpoints will be in the 50s/60s. .LONG TERM...(Saturday through Thursday) ISSUED AT 250 AM CDT Fri Jun 17 2022 Key messages: 1. Pleasant weekend with dry conditions and comfortable humidity. 2. Heat and humidity return next week, with the warmest days Monday and Tuesday. Above normal temperatures and mostly dry weather is expected through much of the extended. Saturday-Sunday...Anamolously strong ridge will build into the Midwest bringing dry weather to the region. Low level flow off Lake Michigan will bring cooler temps (upper 70s Sat, mid 80s Sun) and drier dewpoints (40s/50s) to northwest and north central IL. Elsewhere, temperatures and dewpoints will be slightly higher each day. Regardless, it will be a nice weekend to do anything outside. Early Next Week...large ridge will be overhead with return flow developing over our western CWA early Monday. Taking a look at GEFS/EPS ensemble 850mb 10th/90th percentiles, values over 20C are likely on Monday and Tuesday; some 850mb temps over 25C are depicted in the 90th percentiles. These two days will be the warmest with highs well into the 90s. Dewpoints will also be rising into the mid to upper 60s, which will translate into heat indices over 100 degrees for several hours in the afternoon. Heat headlines may be needed, especially on Tuesday south of I-80. Breezy southwest winds are expected Monday that may bring some relief to the increasing humidity. Tuesday Night-Thursday...latest 00z models disagree on when the upper ridge breaks down, but sometime in this period we will see increasing chances for showers and thunderstorms. A cold front will be the focus for storms and depending on when this comes through will determine storm strength and subsequent rain amounts. The NBM 24-hr QPF probabilities are starting to show a signal for accumulating rain and with a warm and humid airmass in place some decent rain amounts will be possible. Stay tuned. Taking a look at temperatures, the NBM MaxT mean values have highs in the 90s through the end of the work week and even into Week 2. It looks like summer warmth is here to stay for the rest of June. && .AVIATION...(For the 06Z TAFS through 06Z Friday Night) ISSUED AT 1200 AM CDT Fri Jun 17 2022 VFR conditions are expected for this TAF period for all terminals. Light and variable winds to start will increase out of the northwest to around 10 knots by late morning, before veering and becoming light out of the north this evening. && .DVN WATCHES/WARNINGS/ADVISORIES...
