NWS Quad Cities, IA wrote its last area forecast discussion before the first event at Jul 8, 4:30 AM CST, 7 hours earlier.
Area Forecast Discussion National Weather Service Quad Cities IA IL 530 AM CDT Fri Jul 8 2022 ...AVIATION UPDATE... .SYNOPSIS... Issued at 325 AM CDT Fri Jul 8 2022 Nearly stationary frontal boundary extended roughly along Interstate 70 in Missouri, and then into KY. So far, the stronger thunderstorms have occurred just north of the front, barely clipping our far southern counties. Elsewhere in the dvn cwa scattered mainly light rain was falling along Hwy 20 and into nw IL. Early morning temperatures were in the lower to mid 70s. && .SHORT TERM...(Today and Tonight) ISSUED AT 325 AM CDT Fri Jul 8 2022 Headline: Flood Watch for possible flash flooding to continue in our southern counties through 10 am. However, if the bulk of the storms move out sooner the watch may be cancelled earlier. Today: Upper level trough and associated forcing will continue to produce scattered showers and a few thunderstorms through the afternoon. However, the activity should wane later in the day as the system pushes eastward. With weak shear and minimal instability, severe storms are not expected, but locally heavy rainfall is possible. Highs will be in the upper 70s to lower 80s. Tonight: Any lingering showers in our se cwa should end early this evening otherwise clear to partly cloudy skies will be the rule. High pressure will begin to build into the area from the Great Lakes. Lows should bottom out in the lower to mid 60s. .LONG TERM...(Saturday through Thursday) ISSUED AT 325 AM CDT Fri Jul 8 2022 Key messages: 1) For the most part this is a dry extended. 2) There is a chance of thunderstorms on Monday. 3) Seasonal temperatures with the warmest day on Monday. Details: Synoptic overview: Heights rise across the Midwest this weekend while a cold front pushes across the cwa on Monday. This will be followed by a pattern change to a northwest flow for much of next week. With high pressure anchored in the Great Lakes region and into the mid MS Valley, much of next week will be uneventful. Temperatures: For much of the extended forecast, temperatures will be rather seasonable as we head toward the middle of July. This means daily highs in the 80s and daily lows in the 60s. The one exception is on Monday ahead of a cold front with highs in the upper 80s to lower 90s. Precipitation: The only chance for thunderstorms appears to be on Monday into Monday night with the cold front. Otherwise, much of the extended looks dry. With sufficient shear and instability can't rule out strong to severe storms on Monday but low confidence this far out. && .AVIATION...(For the 12Z TAFS through 12Z Saturday Morning) ISSUED AT 525 AM CDT Fri Jul 8 2022 Moist conditions will continue through late afternoon Friday, before VFR weather returns for Friday night. Rain will somewhat increase in coverage, especially in far southeast Iowa and northern Missouri and west central Illinois through the morning. Farther north, low clouds and some passing light rain is possible through early morning. During the day Friday, especially before 21Z, scattered heavy showers or thunderstorms are possible, but these are too scattered to place into the TAFs for now. However, the moist conditions, and rain activity should lead to MVFR to possible IFR cigs developing overnight, lasting into the morning Friday. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE.
