UPDATE

Issued at 806 PM CST Tue Nov 3 2026

Taking a look across the area, dreary and wet conditions persists this evening as pockets of drizzle and light showers rotate through the area. Overall, not expecting any significant changes heading into Wednesday. Depending on if we can keep mid-level saturation overnight, could see more of a widespread transition to drizzle than light showers at times given the lower LCLs. Unfortunately, the wet conditions will then carry over for most of the day on Wednesday as the mid-level low wobbles throughout IA/MN. Continued precipitation chances, will keep temperatures on the cooler side with highs in the low to upper 40s for most areas. Lastly, more breezy conditions are ahead as northwesterly surface winds produce gusts between 25-35 mph for most of the day.

DISCUSSION

Issued at 110 PM CST Tue Nov 3 2026

Low pressure deepens over IA today, then lifts north into MN and restrengthens on Wednesday. This keeps the local area under persistent wrap around warm advection. With plenty of moisture, occasional rain is expected. The better chance for rain will be east of highway 81 this afternoon, then east of the James River on Wednesday as lighter rainfall spreads westward as the low deepens over MN. Low pressure finally begins to drift east Wednesday afternoon into Wednesday night which will bring an end to the rainfall. Additional rainfall amounts will likely be a half an inch to an inch over the next two days. Areas west of the James will see the least amount of rain.

Thursday should see marginally breezy northwest flow help dry out and scour out most of the cloud cover. However the low level thermal field is still on the cool side, so highs will generally be from 45 to 52 degrees.

A nose of surface high pressure builds into the area Friday morning bringing temperatures down into the upper 20s to lower 30s in most locations. Will need to keep an eye on the potential for fog given the very moist soil conditions. If fog can develop with sub-freezing temperatures, roads could end up slippery in the morning.

Sunday through Tuesday will see a stronger northern stream jet bring some milder temperatures with very low chances for rainfall. Lows will likely be from the mid 30s to lower 40s with highs in the mid 50s to lower 60s.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1040 PM CST Tue Nov 3 2026

Mainly IFR and lower will continue this TAF period. Looking at satellite imagery, a mainly IFR to LIFR stratus deck continues to lower this evening with pockets of showers and drizzle. While these conditions will likely continue into Wednesday, should start to see some improvements by Wednesday evening/night as this system pushes eastwards. Otherwise, kept prevailing showers across most TAF sites with breezy northwesterly winds in place through the end of the TAF period.
