Area forecast discussion, Mar 31, 12:50 AM CDT, 2 hours 21 minutes before
Area Forecast Discussion National Weather Service Quad Cities IA IL 1250 AM CDT Fri Mar 31 2023 ...AVIATION UPDATE... .SYNOPSIS... Issued at 200 PM CDT Thu Mar 30 2023 The calm before the storm, as high pressure slides east. A beautiful day was seen throughout, with a mix of clouds/sun and temperatures in the 50s to mid 60s. Storm system emerges off of the Rockies this evening, which will be the focus of the forecast. While the pressure gradient is weak currently, mixing has allowed winds to increase and gust upwards to 25 mph, as warm advection aloft is increasing. This is the time to get all of your ducks in a row, as confidence in severe weather is increasing for tomorrow. Thus, have a plan together and have MULTIPLE ways to receive watches and warnings, in case the forecast continues as is! && .SHORT TERM...(This evening through Friday) Issued at 200 PM CDT Thu Mar 30 2023 Tomorrow, the severe weather day that we have been messaging arrives. Bottom line up front: Confidence continues to increase on severe weather mid-afternoon through the evening on Friday. General timing will be between 2-8pm, with storms moving into our west around 2pm. Currently, the SPC has essentially highlighted our whole area with a Moderate Risk (level 4/5) for Severe Weather, which indicates numerous strong to severe storms are expected. Along with the risk of severe winds, we can expect strong winds through the day as well, as strong gradient winds develop and mixing may also translate strong winds aloft to the surface. Potent wave is currently ejecting off of the central Rockies, which is generating a strong surface low, which continues to deepen, that is set to track through the midwest. Guidance is starting to hone in on a track of the system, which would track the surface low from west-central IA and track it through northeast IA. With that, a strong warm front traversed through the area today, leaving our area in the warm sector of the approaching storm and our eyes are on the cold front and possible occlusion that works its way into the area. Tonight and into Friday morning, we will be dealing with warm advection-induced convection. Some of these storms may be strong, with a low chance to see some severe storms, mainly focusing on hail. Frequent lightning can also be expected from these storms. As this clears out tomorrow morning, we will warm up quite a bit, with temperatures forecast to increase into the upper 60s to mid 70s, especially in our south. Some guidance hints at near 80 degrees in our south! So, well above normal temperatures are forecast ahead of the cold front. Also, collocated with the warm temperatures, impressive warm advection will also pull in anomalous moisture. Thus, dewpoints are currently forecast to be within the mid 50s to low 60s. While the triple point will be the area to focus on, especially for tornado potential, we must also look in the warm sector, especially along/ahead of the cold front. Initially, we may see some more discrete convection form, but given strong forcing and shear parallel to the boundary, we are expecting upscale growth. Although, latest guidance is indicating more of a disconnected line of supercells, also supported by model soundings. Damaging winds and tornadoes will be the main threat, with areas of large hail as well. The SPC has our area hatched on all hazards, indicating that we can see significant winds/hail, along with strong tornadoes. This is a very dynamic system with above normal temperatures and moisture, which will help increase instability quite a bit tomorrow. Guidance has been hinting at CAPE values ranging between 1500-2500 J/kg, which is a bit higher than previous forecast packages, hence the increasing potential for some significant severe. Wind shear is also concerning, ranging between 40-60 KTs in the deep layer, with LLVL shear ranging between 25-40 KTs. This shear in the low levels is very concerning. Just looking at these parameters and features in place, this paints a picture for a pretty strong event. With a dive into the shear profile, hodographs also indicate effective SRH values ranging between 200-300+. Thus, when putting everything together, this is why we are expecting a line of supercell thunderstorms favoring all hazards. Strong winds above the surface will favor damaging winds, as thunderstorm downdrafts that tap into the LLJ will help to translate these winds to the surface. While we can still see some changes in the forecast, it has been rather consistent through the last week with confidence increasing daily. Thus, have plans established in the case of severe weather, especially because tornadoes that develop along the line of convection may develop rapidly and hold the potential to be strong. So, in light of Severe Weather Awareness Week, please have your Weather Radio READY, just in case we see severe weather! Strong to damaging winds will also be a big threat with these storms, so secure objects and furniture outside. .LONG TERM...(Friday night through Thursday) Issued at 200 PM CDT Thu Mar 30 2023 Saturday and Sunday...Potentially wind advisory northwest sfc winds gusting up to 45 MPH thru late Sat morning. This while wrap around cold conveyor induced light snow or snow showers get wind-whipped acrs the landscape. Light snow accumulations of a dusting to a few tenths possible especially along and north of I-80, but lingering mild ground and the wind will make for very difficult true measurements of what will fall. Wind blown falling snow may reduce visibility at times Sat morning and may have to be addressed in any wind headlines. Some afternoon clear out, but it still will be brisk with highs only in the 40s to near 50 in the south. Dry, breezy and milder on Sunday in pre-frontal warming sector with a return to the 60s for much of the fcst area. Monday and Tuesday...A front is projected to continue to slide southward through the area on Monday, making it acrs the southern CWA by evening. Where it stalls being impacted by incoming upstream wave will be a big determinator where overrunning and post frontal showers and a few storms may develop later in the day and into the evening Monday, and will have to at least chc POPs if not likely by evening. Tuesday...an ominous signal indicated by the latest suite of medium range ensembles of another strong neg tilted cyclone ejecting out somewhere acrs the mid CONUS -plains/upper midwest. This system may sprawl out another round of strong to severe storms and strong gradient winds in or near the local area Tue into early Wed with current timing. Another warm sector day as well where currently fcst highs may be a bit too cool. Wednesday and next Thursday...Depending on the midweek cyclone timing, Wed could be a windy cooler dry slot day until wrap around showers possibly skirt acrs the north.
