Regional radar imagery shows a broad swath of precipitation ranging from Nebraska up through Minnesota and down through portions of Iowa and Missouri. There is a break within the cloud cover and precipitation over western Iowa, and this area of clearing is the location to watch for development which could scrape southern Minnesota later this afternoon and evening. RAP soundings and analysis shows the potential for a bit of instability to build within this area of clearing, resulting in little CIN and MUCAPE of 500-1000 J/KG. This couples with a broad area of wind shear associated with a pair of frontal boundaries stretching across the area, with a warm front draped over central to north-central Iowa and a cold front southwest through eastern Nebraska. The warm front will be the key feature to watch as it would provide the wind shear needed for a few storms to maintain strength, should they form within the area of clearing in western Iowa. Right now, the expectation is for a couple storms to move through the periphery of the MPX CWA, with most of the stronger storms remaining southeast of the area along the area more favorable within the warm region south of the warm front and east of the cold front, giving us a marginal severe weather threat for the I-90 corridor which includes a small hail, wind, and tornado chance. Rain showers will continue to churn across the area north of the warm front which is where most of the CWA ends up, with a healthy amount of rain already having fallen and another half to full inch expected before it exits later on Wednesday. Rumbles of thunder are likely to continue through the duration of the system even after the severe weather threat ends later this evening. Aside from the rain, the strong surface pressure gradient resulting in strong sustained winds will continue through this evening with winds at 20-30mph primarily out of the east, with gusts from 40-50mph remaining possible. A few stronger gusts up to 55mph could mix down from any of the stronger showers which develop due to the momentum enhancement from precipitation, however this will be on an isolated basis. Winds will begin to shift northwesterly by tomorrow morning as the surface low slides eastwards, with speeds briefly weakening overnight before increasing to 15-20mph gusting to 30-35mph tomorrow.

As the upper level system occludes and begins to weaken as it heads towards the Great Lakes, the surface low will follow with weakened frontal boundaries, resulting in a downwards trend in rainfall intensity with little in the way of storms overnight and through much of tomorrow, with dry conditions by tomorrow evening. This system will quickly push eastwards, followed by another shot of light rain moving northeast across the plains which could give southern Minnesota and perhaps portions of western Wisconsin another shot of light rain on Thursday. This second, weaker system will be followed by synoptic scale ridging aloft which should keep conditions fairly mild but also a little cooler for the upcoming weekend, with clear skies allowing temperatures to drop and a chance for a hard frost/freeze both Saturday and Sunday mornings. This ridging moves eastwards by Monday, with a hint of another system by the middle of next week.

Ceilings have remained VFR/MVFR through early this afternoon, but expecting them to come down through the period. A broad area of showers with embedded thunderstorms will continue across the region with IFR/LIFR cigs/vis expected with stronger showers and storms. Winds are also quite strong out of the east with gusts of 30-40kts and higher gusts possible with any of those stronger showers and storms. Additionally, LLWS could prove to be an issue, particularly across eastern Minnesota/western Wisconsin as a strong LLJ ramps up this evening. Winds will eventually become north/northwesterly by tomorrow morning for all except KEAU.

KMSP...A brief break in the heavier rain and thunderstorms is expected to last for the next two hours or so before another round pushes northward out of Iowa. By this evening, we'll likely see another break before another round of thunderstorms moves through early Wednesday with IFR/MVFR cigs/vis continuing with northwest winds 20g30kt.

/OUTLOOK FOR KMSP/ THU...VFR. Wind W 15-20G30 kts.
FRI...VFR. Wind WNW 20G30 kts.
SAT...VFR. Wind NW 10-15g25 kts.
