Area Forecast Discussion National Weather Service Des Moines IA 1130 PM CDT Mon Oct 31 2022 ...Updated for the 06z Aviation Discussion... .DISCUSSION.../Tonight through Monday/ Issued at 257 PM CDT Mon Oct 31 2022 Key Messages: -Mild, windy first half of the week with near record-breaking temperatures -Rain/storms begin late Thursday and last well into the weekend Uneventful, dry weather continued to be the main weather story today as weak northwesterly flow advected in more dry air behind the departing surface low. Winds will continue to become more westerly as the day goes on with continued weak flow. The lack of moisture can be credited to the high pressure that is stalled in the Deep South. Until it moves eastward Wednesday, the Gulf moisture will continued to be cut off from progressing northward. Meanwhile, lee side troughing is taking place in eastern Colorado, which will work to increase the pressure gradient across the region and increase winds beginning tomorrow. Have boosted wind and wind gust values on Wednesday and Thursday due to favorable mixing and enhanced wind field. Highs will be unseasonably mild for the next few days with highs reaching the low to mid 70s. Ridging along with the continuous southwesterly winds will push temperatures to approach record- breaking levels for highs Wednesday in a few places. Near max minimum temperatures are also probable Thursday. Meanwhile this week, a trough will deepen over the western CONUS and form a closed low that will migrate to the southwest region by the end of the week. Combined with a wave to the north, rain and thunderstorms from moisture advection will be possible beginning Thursday evening. The initial onset of rain will also have the best chance for thunderstorms. The CSU ML Random Forest Machine (based off of GEFS) highlights the western half of Iowa and is likely latching onto the pre-sunset EML present in soundings. While shear parameters appear high, instability parameters look too weak for severe weather at this time. While the progression and intensity of the low remains in question, this system will produce a healthy amount of rainfall for Iowa regardless. PWATs will exceed 1 inch. The EC EFI pings portions of Iowa for anomalously high QPF Saturday through Monday. The operational NBM has 2.5 inches of total QPF for Des Moines through the entirety of the rain event. The rain will be beneficial for the drought conditions and yields no flooding concerns at this time due to rain accumulating over a longer time span. Temperatures will return to and slightly below average with the arrival and passage of this system. && .AVIATION.../For the 06Z TAFS through 06Z Tuesday night/ Issued at 1130 PM CDT Mon Oct 31 2022 VFR conditions will prevail through the TAF period. && .DMX WATCHES/WARNINGS/ADVISORIES...
