KEY MESSAGES

- Gradual warming and dry over the next several days.

- Breezy to gusty winds at times, in particular Wednesday.

- Low precipitation chances Wednesday night. Greater chances towards next Friday night/Saturday.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 126 PM CST Sat Nov 14 2026

Large Canadian high pressure is stretched across much of the Mississippi River Valley this morning and well north into Ontario. Cool/cold and very dry conditions are in place under this system with few to no clouds and PWAT values near 0.25". Little to no wind is also common across Iowa this afternoon. The high pressure system will move very slowly east the next several days and will keep any Gulf moisture confined to the far Gulf Coast areas. For Iowa, expect gradual warm advection with the slow shift east of the system and perhaps a few passing high level clouds especially with a weak short wave passage on Monday. High temperatures will increase a few degrees on Sunday and again Monday with highs in the 50s on Monday. River valley fog is possible again tonight with low temperatures in the 20s overtopping the warmer open water.

LONG TERM /TUESDAY THROUGH FRIDAY/

Issued at 126 PM CST Sat Nov 14 2026

Upper level ridging will arrive over Iowa on Tuesday as a large trough develops over the Western CONUS. The ridge will transition to southwest flow Tuesday night into Wednesday. A short wave will lift through the southwest flow and will bring low precipitation chances to the state. Precipitation chances will hinge on return moisture and the potential for any saturation given the antecedent very dry mass. The surface high will have moved east enough for a Gulf moisture link to occur but this moisture may not be enough for widespread precipitation. A more significant upper low will enter the southwest CONUS late in the week and will begin to translate eastward towards next weekend. That system appears to present a greater chance for more widespread precipitation. Temperatures will warm from the 50s to the 50s and 60s by Wednesday through Friday. The wind will be breezy to gusty at times at times. Wind gusts of 30 to 40 mph look possible Wednesday.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1132 AM CST Sat Nov 14 2026

VFR conditions are expected to persist through the period.The only potential disruption to this is river valley fog again tonight but that will remain most confined to the immediate river locations. Otherwise light and variable to light south wind with a few passing cirrus at times.
