KEY MESSAGES

- Continued frost and freeze risk tonight/Sunday morning, with additional chances mid to late next week.

- Rain potential returns Monday night.

SHORT TERM
Issued 300 AM CDT Sat Apr 20 2024

Today through Sunday:

Temperatures this morning have fallen into the low to mid 30s in many locations, with the coldest readings along and west of I-90. Clouds have mostly cleared for the time, but are expected to build back into the area today as cyclonic flow persist.
Forecast soundings indicate that cloud depth may be just enough to squeeze out a few sprinkles this afternoon. Highs will be in the mid to upper 40s.

Temperatures tonight will again fall to around freezing, with clearing skies and lower winds compared to the current overnight period. Another freeze warning is likely to be issued later today, likely with some areal expansion eastward compared to the current warning.

Less cloud cover is expected for Sunday, along with neutral to warm temperature advection, despite continued northwest winds.
This will help boost highs into the upper 50s and low 60s.

LONG TERM
Issued 300 AM CDT Sat Apr 20 2024

Sunday night through Friday:

Warm advection is expected Monday, ahead of a compact upper low diving southeastward from the Canadian Prairies into the Dakotas, with highs reaching the 60s. Rain chances will increase into the 60-80 percent range ahead of this feature Monday evening and night. After a brief break on Tuesday, additional precipitation is expected Tuesday night and early Wednesday (70 percent chance), as an associated cold front sweeps through the area.

High pressure will then build into the area, which will set the stage for a cold night Wednesday night into Thursday morning, when temperatures could drop into the 20s in some areas.

Temperatures will warm again for the end of the week and into next weekend, along with renewed chances for showers and thunderstorms.
